A further understanding of the nature and advantages of various embodiments may be realized by reference to the following figures. In the appended figures, similar components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. If only the first reference label is used in the specification, the description is applicable to any one of the similar components having the same first reference label irrespective of the second reference label.
A television receiver may be configured to record multiple television channels over a period of time. Further, such a television receiver may be configured to record one or more television channels for a period of time during which multiple television programs are broadcast. For example, a television receiver may be configured to record a television channel on a daily basis from 6-10 PM. Such recording may be performed on multiple channels simultaneously. For example, each major television network, such as NBC, CBS, ABC, and FOX, may be recorded nightly during primetime (e.g., 7-10 PM). Such recording may result in a large amount of programming being stored by the television receiver such that the television programming is available for a user to playback via a display device, such as a television or monitor, when desired. However, conventional arrangements for allowing the user to interact with the stored recordings of television programs may be inconvenient, inefficient, and/or undesirable.
In some embodiments, a single file is recorded for a television channel for a given consecutive time period. During this time period, multiple television programs are recorded. As such, the channel-specific file can contain multiple television programs. When a playback status element is displayed, playback progress through the entire file and the particular television program may be displayed. Further, visual indicators, referred to as showcards, may be displayed; each showcard represents a television program within the channel-specific file. As such, if a channel-specific file is devoted to a day's primetime broadcasts on a television channel, a showcard may be displayed for each television program broadcast on the television channel during primetime. In some embodiments, playback status elements may be displayed for multiple television channels simultaneously. For example, if two television channels were recorded over the same period of time, a playback status element may be displayed for each of these television channels simultaneously.
Television service provider system 110 and satellite transmitter equipment 120 may be operated by a television service provider. A television service provider may distribute television channels, on-demand programming, programming information, and/or other services to users. Television service provider system 110 may receive feeds of one or more television channels from various sources. Such television channels may include multiple television channels that contain the same content (but may be in different formats, such as high-definition and standard-definition). To distribute such television channels to users, feeds of the television channels may be relayed to user equipment via one or more satellites via transponder streams. Satellite transmitter equipment 120 may be used to transmit a feed of one or more television channels from television service provider system 110 to one or more satellites 130. While a single television service provider system 110 and satellite transmitter equipment 120 are illustrated as part of satellite television distribution system 100, it should be understood that multiple instances of transmitter equipment may be used, possibly scattered geographically to communicate with satellites 130. Such multiple instances of satellite transmitting equipment may communicate with the same or with different satellites. Different television channels may be transmitted to satellites 130 from different instances of transmitting equipment. For instance, a different satellite dish of satellite transmitter equipment 120 may be used for communication with satellites in different orbital slots.
Satellites 130 may be configured to receive signals, such as streams of television channels, from one or more satellite uplinks such as satellite transmitter equipment 120. Satellites 130 may relay received signals from satellite transmitter equipment 120 (and/or other satellite transmitter equipment) to multiple instances of user equipment via transponder streams. Different frequencies may be used for uplink signals 170 from transponder stream 180. Satellites 130 may be in geosynchronous orbit. Each satellite 130 may be in a different orbital slot, such that the signal paths between each satellite, transmitter equipment, and user equipment vary. Multiple satellites 130 may be used to relay television channels from television service provider system 110 to satellite dish 140. Different television channels may be carried using different satellites. Different television channels may also be carried using different transponders of the same satellite; thus, such television channels may be transmitted at different frequencies and/or different frequency ranges. As an example, a first and second television channel may be carried on a first transponder of satellite 130-1. A third, fourth, and fifth television channel may be carried using a different satellite or a different transponder of the same satellite relaying the transponder stream at a different frequency. A transponder stream transmitted by a particular transponder of a particular satellite may include a finite number of television channels, such as seven. Accordingly, if many television channels are to be made available for viewing and recording, multiple transponder streams may be necessary to transmit all of the television channels to the instances of user equipment.
Satellite dish 140 may be a piece of user equipment that is used to receive transponder streams from one or more satellites, such as satellites 130. Satellite dish 140 may be provided to a user for use on a subscription basis to receive television channels provided by the television service provider system 110, satellite transmitter equipment 120, and/or satellites 130. Satellite dish 140 may be configured to receive transponder streams from multiple satellites and/or multiple transponders of the same satellite. Satellite dish 140 may be configured to receive television channels via transponder streams on multiple frequencies. Based on the characteristics of television receiver 150 and/or satellite dish 140, it may only be possible to capture transponder streams from a limited number of transponders concurrently. For example, a tuner of television receiver 150 may only be able to tune to a single transponder stream from a transponder of a single satellite at a time.
In communication with satellite dish 140 may be one or more sets of receiving equipment. Receiving equipment may be configured to decode signals received from satellites 130 via satellite dish 140 for display on a display device, such as display device 160. Receiving equipment may be incorporated as part of a television or may be part of a separate device, commonly referred to as a set-top box (STB). Receiving equipment may include a satellite tuner configured to receive television channels via a satellite. In
Display device 160, which may be a television, monitor, or some other display device, may be used to present video and/or audio decoded by television receiver 150. Television receiver 150 may also output a display of one or more interfaces to display device 160, such as an electronic programming guide (EPG).
Uplink signal 170-1 represents a signal between satellite transmitter equipment 120 and satellite 130-1. Uplink signal 170-2 represents a signal between satellite transmitter equipment 120 and satellite 130-2. Each of uplink signals 170 may contain streams of one or more different television channels. For example, uplink signal 170-1 may contain a certain group of television channels, while uplink signal 170-2 contains a different grouping of television channels. Each of these television channels may be scrambled such that unauthorized persons are prevented from accessing the television channels.
Transponder stream 180-1 represents a signal between satellite 130-1 and satellite dish 140. Transponder stream 180-2 represents a signal path between satellite 130-2 and satellite dish 140. Each of transponder streams 180 may contain one or more different television channels in the form of transponder streams, which may be at least partially scrambled. For example, transponder stream 180-1 may include a first transponder stream containing a first group of television channels, while transponder stream 180-2 may include a second transponder stream containing a different group of television channels. A satellite may transmit multiple transponder streams to user equipment. For example, a typical satellite may relay thirty-two transponder streams via corresponding transponders to user equipment. Further, spot beams are possible. For example, a satellite may be able to transmit a transponder stream to a particular geographic region (e.g., to distribute local television channels to the relevant market). Different television channels may be transmitted using the same frequency of the transponder stream to a different geographic region.
Network 190 may serve as a secondary communication channel between television service provider system 110 and television receiver 150. Via such a secondary communication channel, bidirectional exchange of data may occur. As such, data may be transmitted to television service provider system 110 via network 190. Data may also be transmitted from television service provider system 110 to television receiver 150 via network 190. Network 190 may be the Internet. While audio and video services may be provided to television receiver 150 via satellites 130, feedback from television receiver 150 to television service provider system 110 may be transmitted via network 190.
Processors 210 may include one or more specialized and/or general-purpose processors configured to perform processes such as tuning to a particular channel, accessing and displaying EPG information from EPG database 230, and/or receiving and processing input from a user. For example, processors 210 may include one or more processors dedicated to decoding video signals from a particular format, such as MPEG, for output and display on a television and for performing decryption. It should be understood that the functions performed by various modules of
Control processor 210-1 may communicate with tuning management processor 210-2. Control processor 210-1 may control the recording of television channels based on timers stored in DVR database 245. Control processor 210-1 may initiate recording of a television channel by sending a record command along with an indication of the television channel to be recorded to tuning management processor 210-2. Control processor 210-1 may not send a second record command (if additional recording is to begin at the same time) until an acknowledgement that recording of the first television channel has successfully been received and initiated by tuning management processor 210-2. Control processor 210-1 may also provide commands to tuning management processor 210-2 when recording of a television channel is to cease. In addition to providing commands relating to the recording of television channels, control processor 210-1 may provide commands to tuning management processor 210-2 that indicate television channels to be output to audio/video decoder 233 for output to a presentation device, such as a television.
Control processor 210-1 may also communicate with network interface 220 and user interface 250. Control processor 210-1 may handle incoming data from network interface 220 and user interface 250. Additionally, control processor 210-1 may be configured to output data via network interface 220.
Tuners 215 may include one or more tuners used to tune to television channels, such as television channels transmitted via satellite or cable. In the illustrated embodiment of television receiver 200, three tuners are present (tuner 215-1, tuner 215-2, and tuner 215-3). Each tuner contained in tuners 215 may be capable of receiving and processing a transport stream of data from a satellite transponder (or a cable RF channel) at a given time. This transport stream may contain audio and video data for multiple television channels in addition to other data. As such, a single tuner may tune to a single transponder (or, for a cable network, a single cable RF channel). If tuners 215 include multiple tuners, one tuner may be used to tune to a television channel on a first transponder stream for display using a television, while another tuner may be used to tune to a television channel on a second transponder for recording and viewing at some other time. If multiple television channels transmitted on the same transponder stream are desired, a single tuner of tuners 215 may be used to receive the signal containing the multiple television channels for presentation and/or recording. Tuners 215 may receive commands from tuning management processor 210-2. Such commands may instruct tuners 215 which frequencies are to be used for tuning.
Network interface 220 may be used to communicate via an alternate communication channel with a television service provider. For example, the primary communication channel may be via satellite (which may be unidirectional to the STB) and the alternate communication channel (which may be bidirectional) may be via a network, such as the Internet. Referring back to
Storage medium 225 may represent a non-transitory computer-readable storage medium. Storage medium 225 may include memory and/or a hard drive. Storage medium 225 may be used to store information received from one or more satellites and/or information received via network interface 220. Storage medium 225 may store information related to EPG database 230, and/or DVR database 245. In some embodiments, storage medium 225 may also be used to store various tables, such as NIT 240, PMT 257, and/or PAT. Recorded television programs may be stored using storage medium 225. Storage medium 225 may be partitioned or otherwise divided such that predefined amounts of storage medium 225 are devoted to storage of omnibus channel files and user-selected television programs.
EPG database 230 may store information related to television channels and the timing of programs appearing on such television channels. EPG database 230 may be stored using storage medium 225, which may be a hard drive. Information from EPG database 230 may be used to inform users of what television channels or programs are popular and/or provide recommendations to the user. Information from EPG database 230 may provide the user with a visual interface displayed by a television that allows a user to browse and select television channels and/or television programs for viewing and/or recording. Information used to populate EPG database 230 may be received via network interface 220 and/or via satellites, such as satellites 130 of
In addition to being used to provide users with information about scheduled programming, information from EPG database 230 may be used to determine when television programs begin and end for the purposes of recording. For instance, if a channel-specific file is recorded that contains multiple television programs, the start and end of time of specific television programs within the channel-specific file may be based on the start and end times indicated in the EPG. Other data may be stored for the EPG that may be useful in managing channel-specific files, such as series identifiers and episode identifiers (which may be used by a television service provider to identify particular television programs).
Audio/video decoder 233 may serve to convert encoded video and audio into a format suitable for output to a display device. For instance, audio/video decoder 233 may receive MPEG video and audio from storage medium 225 or descrambling engine 265 to be output to a television. MPEG video and audio from storage medium 224 may have been recorded to DVR database 245 as part of a previously-recorded television program. Audio/video decoder 233 may convert the MPEG video and audio into a format appropriate to be displayed by a television or other form of display device and audio into a format appropriate to be output from speakers, respectively.
Television interface 235 may serve to output a signal to a television (or another form of display device) in a proper format for display of video and playback of audio. As such, television interface 235 may output one or more television channels, and stored television programming from storage medium 225 (e.g., television programs from DVR database 245 and/or information from EPG database 230) to a television for presentation.
The Network Information Table (NIT) 240 may store information used by television receiver 200 to access various television channels. NIT 240 may be stored locally by a processor, such as by tuning management processor 210-2. Information used to populate NIT 240 may be received via satellite (or cable) through tuners 215 and/or may be received via network interface 220 from the television service provider. As such, information present in NIT 240 may be periodically updated. In some embodiments, NIT 240 may be locally-stored by television receiver 200 using storage medium 225. Generally, NIT 240 may store information about a service provider network, such as a satellite-based service provider network. Information that may be present in NIT 240 may include: television channel numbers, satellite identifiers, frequency identifiers and/or transponder identifiers for various television channels. In some embodiments, NIT 240 may contain additional data or additional tables may be stored by the television receiver. For example, specific audio PIDs and video PIDs may not be present in NIT 240; a channel identifier may be present within NIT 240 which may be used to look up the audio PIDs and video PIDs in another table, such as a program map table (PMT). In some embodiments, a PID associated with the data for the PMT is indicated in a separate table, program association table (PAT), which is not illustrated in
Table 1 provides a simplified example of NIT 240 for several television channels. It should be understood that in other embodiments, many more television channels may be represented in NIT 240. NIT 240 may be periodically updated by a television service provider. As such, television channels may be reassigned to different satellites and/or transponders, and television receiver 200 may be able to handle this reassignment as long as NIT 240 is updated.
Based on information in the NIT, it may be possible to determine the proper satellite and transponder to which to tune for a particular television channel. In some embodiments, the NIT may list a particular frequency to which to tune for a particular television channel. Once tuned to the proper satellite/transponder/frequency, a known PMT PID may be used to retrieve a program map table that indicates the PIDs for audio and video streams of television channels transmitted by that transponder.
It should be understood that the values provided in Table 1 are for example purposes only. Actual values, including how satellites and transponders are identified, may vary. Additional information may also be stored in NIT 240. Additional information on how NIT 240, as indicated in Table 1, may be used is provided in reference to
A Digital Video Recorder (DVR) may permit a television channel to be recorded for a period of time. DVR functionality of television receiver 200 may be managed by control processor 210-1. Control processor 210-1 may coordinate the television channel, start time, and stop time of when recording of a television channel is to occur. DVR database 245 may store information related to the recording of television stations. DVR database 245 may store timers that are used by control processor 210-1 to determine when a television channel should be tuned to and its programs recorded to DVR database 245 of storage medium 225. In some embodiments, a limited amount of storage medium 225 may be devoted to DVR database 245. Timers may be set by the television service provider and/or one or more users of television receiver 200.
The DVR functionality of control processor 210-1 may have multiple modes. First, the DVR functionality of control processor 210-1 may be configured to record individual television programs selected by a user to DVR database 245. Using EPG database 230, a user may select a particular television program. Based on the date, time period, and television channel indicated by EPG database 230, Control processor 210-1 may record the associated television program to DVR database 245. Second, DVR database 245 may be used to store recordings of predefined periods of time on one or more television channels. These predefined periods of time may include one or more television programs. For example, primetime on a particular television network may be recorded each weekday night. Further, multiple television channels may be recorded for such predefined periods of time. Such recording of television channels for predefined periods of time may be defined by the television service provider.
As an example of this second mode of DVR functionality, a television service provider may configure television receiver 200 to record television programming on multiple, predefined television channels for a predefined period of time, on predefined dates. For instance, a television service provider may configure television receiver 200 such that television programming may be recorded from 7 to 10 PM on NBC, ABC, CBS, and FOX on each weeknight. If a television program is selected for recording by a user and is also specified for recording by the television service provider, the user selection may serve as an indication to save the television program for an extended time (beyond the time which the predefined recording would otherwise be saved).
User interface 250 may include a remote control (physically separate from television receiver 200) and/or one or more buttons on television receiver 200 that allow a user to interact with television receiver 200. User interface 250 may be used to select a television channel for viewing, view information from EPG database 230, and/or program a timer stored to DVR database 245, wherein the timer is used to control the DVR functionality of control processor 210-1.
Referring back to tuners 215, television channels received via satellite (or cable) may contain at least some scrambled data. Packets of audio and video may be scrambled to prevent unauthorized users (e.g., nonsubscribers) from receiving television programming without paying the television service provider. When a tuner of tuners 215 is receiving data from a particular transponder of a satellite, the transponder stream may be a series of data packets corresponding to multiple television channels. Each data packet may contain a packet identifier (PID), which, in combination with NIT 240 and/or PMT 257, can be determined to be associated with a particular television channel. Particular data packets, referred to as entitlement control messages (ECMs) may be periodically transmitted. ECMs may be associated with another PID and may be encrypted; television receiver 200 may use smart card 260 to decrypt ECMs. Decryption of an ECM may only be possible if the user has authorization to access the particular television channel associated with the ECM. When an ECM is determined to correspond to a television channel being stored and/or displayed, the ECM may be provided to smart card 260 for decryption.
When smart card 260 receives an encrypted ECM, smart card 260 may decrypt the ECM to obtain some number of control words. In some embodiments, from each ECM received by smart card 260, two control words are obtained. In some embodiments, when smart card 260 receives an ECM, it compares the ECM to the previously received ECM. If the two ECMs match, the second ECM is not decrypted because the same control words would be obtained. In other embodiments, each ECM received by smart card 260 is decrypted; however, if a second ECM matches a first ECM, the outputted control words will match; thus, effectively, the second ECM does not affect the control words output by smart card 260. Smart card 260 may be permanently part of television receiver 200 or may be configured to be inserted and removed from television receiver 200.
Tuning management processor 210-2 may be in communication with tuners 215 and control processor 210-1. Tuning management processor 210-2 may be configured to receive commands from control processor 210-1. Such commands may indicate when to start/stop recording a television channel and/or when to start/stop causing a television channel to be output to a television. Tuning management processor 210-2 may control tuners 215. Tuning management processor 210-2 may provide commands to tuners 215 that instruct the tuners which satellite, transponder, and/or frequency to tune to. From tuners 215, tuning management processor 210-2 may receive transponder streams of packetized data. As previously detailed, some or all of these packets may include a PID that identifies the content of the packet.
Tuning management processor 210-2 may be configured to create one or more PID filters 255 that sort packets received from tuners 215 based on the PIDs. When a tuner is initially tuned to a particular frequency (e.g., to a particular transponder of a satellite), a PID filter may be created based on a PID of PMT data. The PID of PMT data packets may be known because it is stored as part of NIT 240 or another table, such as a PAT. From the PMT data packets, PMT may be constructed by tuning management processor 210-2. Table 2 provides an exemplary extract of a PMT. PMT 257 may be specific to a particular transponder. As such, if tuning to a different transponder occurs, a new PMT may be created for the different transponder.
Accordingly, based on the information present in PMT 257, the audio and video PIDs for specific television channels may be identified. A television channel may have multiple audio PIDs due to a second audio program (SAP), which may be in a different language.
It should be understood that the values provided in Table 2 are for example purposes only. Actual values may vary. Additional information or less information may also be stored in PMT 257.
PID filters 255 may be configured to filter data packets based on PIDs. In some embodiments, PID filters 255 are created and executed by tuning management processor 210-2. In other embodiments, separate hardware may be used to create and execute such PID filters. Depending on a television channel selected for recording/viewing, a PID filter may be created to filter the video and audio packets associated with the television channel (based on the PID assignments present in PMT 257). For example, if a transponder data stream includes multiple television channels, data packets, corresponding to a television channel that is not desired to be stored or displayed by the user, may be ignored by PID filters 255. As such, only data packets corresponding to the one or more television channels desired to be stored and/or displayed may be filtered and passed to either descrambling engine 265 or smart card 260; other data packets may be ignored. For each television channel, a stream of video packets, a stream of audio packets (one or both of the audio programs) and/or a stream of ECM packets may be present, each stream identified by a PID. In some embodiments, a common ECM stream may be used for multiple television channels. Additional data packets corresponding to other information, such as updates to NIT 240, may be appropriately routed by PID filters 255. At a given time, one or multiple PID filters may be executed by tuning management processor 210-2.
Descrambling engine 265 may use the control words output by smart card 260 in order to descramble video and/or audio corresponding to television channels for storage and/or presentation. Video and/or audio data contained in the transponder data stream received by tuners 215 may be scrambled. Video and/or audio data may be descrambled by descrambling engine 265 using a particular control word. Which control word output by smart card 260 to be used for successful descrambling may be indicated by a scramble control identifier present within the data packet containing the scrambled video or audio. Descrambled video and/or audio may be output by descrambling engine 265 to storage medium 225 for storage (in DVR database 245) and/or to audio/video decoder 233 for output to a television or other presentation equipment via television interface 235.
Television receiver 200 may be configured to record channel-specific files that contain multiple television programs. For example, processors 210 may be configured to cause multiple television channels to be recorded to channel-specific files, in which each file contains multiple television programs. These channel-specific files may be stored by DVR database 245. A user may be permitted to select a channel-specific file or a specific television program from within a channel-specific file for playback.
Control interface module 232 may contain data used to create various user interfaces that allow a user to interact with stored channel-specific files. For example, embodiments of such interfaces are described in relation to
For simplicity, television receiver 200 of
In illustrated embodiment 300, playback status element 320 includes a progress bar, which indicates a start point 311 and an end point 312 for the channel-specific file. Start point 311 may correspond to the time at which recording of the television channel commenced. End point 312 may correspond to the time at which recording of the television channel ended. In some embodiments, additionally or alternatively to indicating the time at which recording commenced and ended, a recording timer may be indicated that has the start time at time “0” and the end point being the amount of time of recording. For example, in illustrated embodiment 300, the end point may be three hours. Also within playback status element 320, start points and end points for particular television programs are indicated, such as program start point 313 and program end point 314 for the television program “So Happy.” Program end point 314 may also serve as the start point for a television program broadcast after “So Happy.”
Channel status 330 indicates the television channel, date, and time period for which the television channel was recorded. The time period may include time periods during which multiple television programs were broadcast on the television channel consecutively. To be clear, “television program” is defined to include content broadcast on a television channel. It may be a one-time production or part of a periodically recurring series. Television programs are typically, at minimum, scheduled for thirty minutes, including commercial breaks. Television programs do not include commercials, which may be broadcast before, after, and during the broadcast of television programs. For example, if a television program is scheduled for thirty minutes, that broadcast period may include several minutes at the beginning and/or end of commercials. Further, during the broadcast of the television program, multiple commercials may be present.
In some embodiments, by selecting channel status 330, a user may be permitted to select a different television channel, date, and/or time period for playback. For example, multiple other television channels may have been recorded during the same time period and/or date as channel “CBC.” Recordings of these television channels may also be available for playback in the form of a channel-specific file that contains multiple television programs. As such, if channel status 330 is selected, a user may be prompted to select a different channel, date, and/or time period.
If one or more other television channels were recorded during the same time period, these other television channels may have been received by the television receiver via a same tuner. A single tuner of a television receiver may be used to receive each of the television channels over a same period of time for recording if the multiple television channels are broadcast as part of a same transponder stream. As such, multiple television channels may be received and recorded while limiting the number of tuners required to receive the television channels to one.
In illustrated embodiment 300, playback status element 320 includes a progress bar on which the times at which various television programs begin are indicated. It should be understood that in other embodiments, playback status element 320 may include a display arrangement other than a progress bar. In illustrated embodiment 300, an indication of a start time of each television program within the channel-specific file is indicated. These start times may be based on the scheduled start time as indicated by EPG data. EPG data may be used to create a bookmark file containing information about each television program present within the channel-specific file (e.g., a start time, a name of the television program, graphical data for a showcard, etc.)
The start time of each television program is indicated in playback status element 320 by a showcard. A showcard may include text and/or a graphic that is indicative of the television program. For simplicity, in embodiment 300, text that indicates the title of the television program is used. In other embodiments, a graphic that is indicative of the television program may be used. For example, when a television program is selected or highlighted based on user input in an EPG display created by a television receiver, “poster art” for the television program may be presented. This poster art may show an image selected to represent the television show, such as the major actors and/or actresses from the television show posing and/or may include the title of the television program. This poster art may be received and stored by the television receiver for use in an EPG display. This poster art may be received by the television receiver via the television service provider's network, such as a satellite-based television distribution network. In addition to using such poster art for display when the television program is selected via an EPG display, the poster art may be used for showcards 350. In some embodiments, a screenshot from the recorded television program may be used for the showcard. This screenshot may be selected by the television service provider, be randomly chosen, or be selected from a preselected point in time within the recording of the television program.
Showcard 350-1 indicates that the television show “Shark Land” begins at 7:00 PM. Showcard 350-2 indicates that the television show “True Friend”, which airs immediately after “Shark Land” was recorded as part of the same channel-specific file, begins at a later time. In some embodiments, a time may be indicated for the start of “True Friend.” For each showcard, some form of indicator may be present on a progress bar, such as a line associated with each showcard 350, which indicates the point on the progress bar at which the television programs associated with the showcard begins. In illustrated embodiment 300, the start of “True Friend,” as indicated by showcard 350-2 signals the end of “Shark Land.” The amount of space along the progress bar between the indicated start points of television programs may be indicative of the length of time of the television program (e.g., twice as much space may be present for a television program that is an hour long compared to a television program that is 30 minutes long).
Playback indicator 340 indicates the current point in playback. As such, while, for simplicity, not illustrated in
Playback status element 320 may only be displayed when a user has provided a “pause” or “stop” command to the television receiver regarding playback of the channel-specific file. In some embodiments, while the channel-specific file is being played back, playback status element 320 may be displayed. Such display may be based on a user providing a “playback status” or similar command. In some embodiments, whenever a new television program begins or ends being played back, playback status element 320 is displayed for a predefined period of time (e.g., 10 seconds).
Playback status element 320 may be presented before the entire channel-specific file has been recorded. For example, a user may be permitted to begin playback of a portion of the channel-specific file before the entire file has been recorded. As an example, a user may be permitted to watch “Shark Land” while recording of the file (e.g., a later portion of “Shark Land” or a later broadcast television program) is occurring. Portions of the channel-specific file that have yet to be recorded may be displayed differently in playback status element 320. For instance, portions of the status bar and/or showcards that correspond to unrecorded portions of the channel-specific file may be grayed out to indicate unavailability. Similar playback during recording may also occur in relation to the other embodiments detailed herein.
The television program names, television channel name, number of television programs, time period, and the specific arrangement of graphical elements of embodiment 300 are for example purposes only. It should be understood that the examples and details provided in relation to embodiment 300 may be applied to various implementations of similar presentation techniques that allows a user to interact with recorded television programs.
In playback status element 410 of
A user may be able to select a showcard by manipulating a user input device, such as a remote control. When a showcard is selected, such as showcard 450-3, it may be presented in a large format. A second user input, such as a “click” or other “OK” selection, may result in the television program associated with the selected showcard being played. In embodiment 400, a user has selected showcard 450-3. Input may be received from the user indicating playback of “So Happy” is to commence, thus resulting in playback indicator 340 jumping to the time associated with the beginning of “So Happy.” Thus playback indicator 340 would become playback indicator 420. This start time may be based on a bookmark file created based on EPG data stored by the television receiver. To a user, the change results in a different television program commencing playback; functionally, the television receiver is changing a playback location within a single channel-specific file. In some embodiments, showcard 450-3 may remain in a large format while the associated television program is being played back. As such, the television program currently being played back and/or a selected showcard may be presented in a large format.
It should be understood that in other embodiments, other arrangements may be used for emphasizing a showcard rather than presenting it in a large format. For instance, showcards may be shown in black and white, unless selected. If selected, the showcards may be shown in color. Other uses of color for highlighting or selecting may be possible. In some embodiments, if a television program is not selected, its associated showcard may be hidden. As such, in an alternate of embodiment 400, showcards 450-1, 450-2, and 450-4 may not be displayed. In some embodiments, such showcards which are not selected may be more transparent than showcard 450-3 (thus allowing a television program being displayed behind playback status element 410 to be viewed.
The television program names, television channel name, number of television programs, time period, and the specific arrangement of graphical elements of embodiment 400 are for example purposes only. It should be understood that the examples and details provided in relation to embodiment 400 may be applied to various implementations of similar presentation techniques that allow a user to interact with recorded television programs.
Playback status element 510 indicates multiple television channels which were recorded during an overlapping time period on a same day. Channel-specific indicator 520-1, channel-specific indicator 520-2, channel-specific indicator 520-3, and channel-specific indicator 520-4 are each associated with a different television channel recorded during a period of time. Each of these television channels may have been recorded over a same time period. Each of these television channels may have been received for recording using a single tuner of a television receiver. Each channel-specific indicator of channel-specific indicators 520 may have text and/or graphics specific to the television channel. As an example, a channel-specific indicator for NBC may be NBC's peacock graphic, while CBS's channel-specific indicator could be the CBS “eye” graphic. In illustrated embodiment 500, the channel associated with channel-specific indicator 520-4 is selected for playback control, as indicated by selection graphic 521 highlighting details of a file associated with channel-specific indicator 520-4. A user may be permitted to select another television channel for playback by selecting a different channel-specific indicator using a user input device. Each channel-specific indicator of channel-specific indicators 520 may be associated with a particular file recorded over a time period for the television channel. A file covering a same time period on a same day may have been recorded by the television receiver for each of the television channels. In some embodiments, a single tuner of the television receiver may have been used to receive each of the four channels over the same period of time. A separate file may be created for each channel. As such, a selection of a channel-specific indicator of channel-specific indicators 520 may result in a different channel-specific file being selected for playback.
Since channel-specific indicator 520-4 is selected, details regarding playback of the associated channel-specific file are displayed via selection graphic 521. Each television program present within this channel-specific file is indicated. For example, television program 540-1 has text indicating the title of a television program within the television channel-specific file. Times 550 indicate start and end times for the associated channel-specific file (time 550-1 and time 550-5) and individual television programs within the channel-specific file. For example, television program 540-1 begins at time 550-3 and ends at time 550-4. Graphic 541 may be associated with television program 540-2. Graphic 541 may be an icon associated with the specific television program, may indicate the type of television program (e.g., sitcom, drama, movie), may indicate a rating of the television program (e.g., G, PG, R), or may have some other meaning Playback indicator 545 indicates the current playback location within the channel-specific file being played back. A time may be presented that is associated with playback indicator 545, the time indicating the time remaining in the playback of the channel-specific file and/or the time remaining in the playback of the specific television program.
In illustrated embodiment 500, only a single showcard is presented at a given time. As such, by selecting a television program 540-1, showcard 530 may be presented, with poster art specific to that television program. A user may select graphical element 535 to cause the television receiver to commence playback of television program 540-1. In illustrated embodiment 500, the user may be permitted to manipulate cursor 512 to provide input via playback status element 510. Showcard 530 and graphical element 535 may be presented as part of pop-up 531, which is specific to television program 540-1. The content of pop-ups for other television programs may vary.
User input, such as a user manipulating an up or down arrow on a user input device, may result in a channel-specific file associated with a different television channel being selected. Each of these other channel-specific files may have been recorded during a same period of time as the television channel associated with channel-specific indicator 520-4. If another television channel is selected, such as the channel associated with channel-specific indicator 520-2, a status bar associated with the channel represented by channel-specific indicator 520-2 may be presented. The television programming, start times, and end times then presented correspond to the television channel represented by channel-specific indicator 520-2. In order to keep the status bar located at the bottom of the screen (which may be to limit how obscuring of the presently-displayed television program), channel-specific indicator 520-2 may be moved to the illustrated location of channel-specific indicator 520-4. In other embodiments, the status bar may be presented directly next to the channel-specific indicator 520-2 at the location illustrated.
The television program names, television channel name, number of television programs, time period, and the specific arrangement of graphical elements of embodiment 500 are for example purposes only. It should be understood that the examples and details provided in relation to embodiment 500 may be applied to various implementations of similar presentation techniques that allow a user to interact with recorded television programs.
In embodiment 600, a user may have selected the television channel associated with channel indicator 520-3. As such, selection graphic 521 now displays details related to the television channel associated with channel indicator 520-3. To do this, the television receiver may have access to the bookmark file for details about the contents of the channel-specific file associated with channel-specific indicator 520-3. The bookmark file may contain details such as start and end times for television programs, the titles for television programs, poster art for the television programs, and/or other EPG which may be presented to the user. In some embodiments, the offset data, which indicates a file position at which the television program begins, may be stored as part of the bookmark file. This offset data may have been identified as the channel-specific file was being recorded. For example, when a particular television program has begun recording (according to a start time indicated in the EPG data), a “check size” command may be processed to determine at what point in the sequential file the television program begins. Further, the location of selection graphic 521 has been moved to correspond to a channel-specific indicator 520-3. The start times, end times, television programs, and showcards may be specific to the television programs stored as part of the channel-specific file linked with channel-specific indicator 520-3. The time period during which this channel-specific file was recorded may overlap or match the time period during which the channel-specific file associated with channel-specific indicator 520-4 was recorded.
In embodiments 500 and 600, selection graphic 521 only displays an indication of a single channel-specific file's content at a given time. In other embodiments, it should be understood that an indication of the content of multiple television channels may be presented simultaneously by a television receiver. For example, a status bar for each channel-specific indicator may be presented simultaneously. In some embodiments, two, three, or four status bars may be presented simultaneously as part of playback status element 610.
In some embodiments, multiple television programs may be played back simultaneously, such as via a picture-in-picture (PIP) arrangement or a split-screen arrangement. For example, a user may indicate a first television program using playback status element 610 for primary playback and the user may indicate a second television program (which was recorded as part of the same channel-specific file or a different channel-specific file) for secondary playback (e.g., in a small portion of the screen). Such an arrangement may be useful if the user is watching sports and wants to watch a less desired game via a PIP arrangement. Therefore, it may be possible for a user to use playback status element 610 to select, for simultaneous playback, multiple television programs which were: broadcast concurrently on different channels, broadcast at different times of the same television channel, and/or broadcast on different television channels at different dates/times.
The television program names, television channel name, number of television programs, time period, and the specific arrangement of graphical elements of embodiment 600 are for example purposes only. It should be understood that the examples and details provided in relation to embodiment 600 may be applied to various implementations of similar presentation techniques that allow a user to interact with recorded television programs.
Referring back to embodiment 300 of
Event status 710 may be a pop-up displayed over video being output by the television receiver when a television program from a channel-specific file has completed being played back. In some embodiments, the next television program recorded as part of the channel-specific file may begin playing in the background on the display device. In other embodiments, playback of the channel-specific file may be paused or stopped until user input is received in the event status 710.
In the illustrated embodiment 700, showcard 720 of poster art for the television program that is completed being played back is displayed as part of event status 710. In some embodiments, a showcard for the next television program recorded as part of the channel-specific file may be presented additionally or instead. Upcoming program indicator 730 may indicate the next television program recorded as part of the channel-specific file.
Event status 710 may present a user with three options. A first option may be to watch the next television program that was recorded as part of the channel-specific file. For example, referring back to embodiment 300, if event status 710 is presented following the conclusion of “Shark Land,” the user may select option 740 in order to begin playback of “True Friend.” A second option may be to return to a DVR menu via select option 750. The DVR menu may allow the user to select a different channel and/or date in order to select other television programming for playback. In some embodiments, a return to the DVR menu may automatically occur if the user has selected a specific television program for playback rather than a channel-specific file for playback. As an example of this, referring to embodiment 300, if the user selected “CBC” Jul. 27, 2012 for playback, event status 710 may be presented upon conclusion of playback of the television program of the channel-specific file being completed. If the user had specifically selected “True Friend” for playback (e.g., via a DVR television program listing), event status 710 may not be presented, but rather the television receiver may return to a DVR menu. A third option may be for the user to provide input causing the television receiver to switch to live television via select option 760. This may result in the television receiver outputting television programming currently being received on a television channel. The television channel that is output for display by the television receiver may be the same television channel as last output live or may be the television channel that previously broadcast the television program which was recorded by the television receiver. For instance, referring to embodiment 300, upon conclusion of “True Friend” being played back, event status 710 being displayed, and a user selecting select option 760, the television channel “CBC” may be output live by the television receiver to a display device.
The television program names, television channel name, number of television programs, time period, and the specific arrangement of graphical elements of embodiment 700 are for example purposes only. It should be understood that the examples and details provided in relation to embodiment 700 may be applied to various implementations of similar presentation techniques that allow a user to interact with recorded television programs.
A television service provider may identify television programs in suggestion region 820 that fans of the television program that has completed playback may enjoy. Suggestion region 820 may use showcards for the suggested television programs. In some embodiments, rather than showing suggested television programs, television programs that were recorded over the same time period on other television channels may be indicated in suggestion region 820. For example, if the television program that completed playback was broadcast on Apr. 27, 2012 from 8-8:30 PM, television programs recorded from a broadcast of another television channel on Apr. 27, 2012 from 8-8:30 PM may be suggested to the user via suggestion region 820.
Using the previously-described television distribution systems and television receivers, various methods may be performed to manage playback of stored television programs.
At step 905, EPG data for a television channel may be received and stored by a television receiver. The EPG data may be transmitted to the television receiver via a television service provider's network. For instance, if satellite-based, television distribution system 100 of
At step 910, the television channel may be recorded for a period of time. This may result in a channel-specific file being created for the television channel. This channel-specific file may contain multiple television programs. For example, a television channel may be recorded over a period of time such as multiple hours. During this period of time, two or more television programs may be broadcast on the television channel. Further, multiple television channels may be recorded over the same period of time by the television receiver. These multiple television channels may be received using a single tuner of the television receiver. Further, these multiple television channels may be transmitted to the television receiver via a single transponder stream by a television service provider, thus allowing a single tuner to be used to receive the multiple television channels. The recording of the television channel at step 910 may be managed by the television service provider. The television service provider may configure the television receiver to record a particular television channel over a particular time period. As an example of this, a television service provider may configure television receivers of its subscribers to record television programming on each of the four major television networks (ABC, CBS, NBC, and FOX) from 7-10 PM nightly (using a single tuner of the subscriber's television receiver).
At step 915, a bookmark file may be created for the channel-specific file recorded at step 910. Creation of the bookmark file may occur as recording of the television channel at step 910 is performed. The bookmark file created at step 915 may contain some or all of the EPG data related to television programs recorded as part of the channel-specific file. Additional information may also be included in the bookmark file, such as an indication of where individual television programs are located within the channel-specific file. In some embodiments, a file offset may be used. For example, as a television channel-specific file is being recorded at step 910, when EPG data indicates that a next television program is scheduled to begin being broadcast, the file size of the channel-specific file may be determined. This measured file size may serve as an offset to indicate the point within the file at which the next television program is scheduled to begin. The offset may be stored to the bookmark file for each television program recorded within the channel-specific file.
At step 920, user input may be received requesting playback of the recording of the television channel. For instance, the user may specify a television channel and a date for which playback is requested. In some embodiments, the user may select a particular television program which was recorded as part of the channel-specific file for playback. As an example, referring to embodiment 300 of
At step 930, a playback status element may be presented for the television channel-specific file recorded at step 910. Data used for displaying the playback status element at step 930 may at least be partially based on the bookmark file created at step 915. Embodiments 300, 400, 500, and 600 of
At step 1005, EPG data for multiple television channels may be received and stored by a television receiver. The EPG data may be transmitted to the television receiver via a television service provider's network. For instance, if satellite-based, television distribution system 100 of
At step 1010, the multiple television channels may be recorded concurrently for a period of time. These television channels may be received using a single tuner of the television receiver. This may result in a channel-specific file being created for each of the television channels. The channel-specific files may each contain multiple television programs. For example, one of the television channels may be recorded over a period of time such as multiple hours. During this period of time, two or more television programs may be broadcast on the television channel. The multiple television channels may be transmitted to the television receiver via a single transponder stream by a television service provider, thus allowing the single tuner to be used to receive the multiple television channels. The recording of the television channel at step 1010 may be managed by the television service provider. The television service provider may configure the television receiver to record a particular television channel over a particular time period. As an example of this, a television service provider may configure television receivers of its subscribers to record television programming on each of the four major television networks (ABC, CBS, NBC, and FOX) from 7-10 PM nightly (using a single tuner of the subscriber's television receiver).
At step 1015, a bookmark file may be created for each channel-specific file recorded at step 1010. Creation of each bookmark file may occur as recording of the television channel at step 1010 is performed. The bookmark files created at step 1015 may contain some or all of the EPG data related to television programs recorded as part of the channel-specific files. Additional information may also be included in the bookmark files, such as an indication of where individual television programs are located within the channel-specific files. In some embodiments, a file offset may be used for such location identification. For example, as a television channel-specific file is being recorded at step 1010, when EPG data indicates that a time has been reached when the next television program is scheduled to begin being broadcast, the file size of the channel-specific file may be determined. This measured file size may serve as an offset to indicate the point within the file at which the next television program is scheduled to begin. The offset may be stored to the bookmark file for each television program recorded within the channel-specific file.
At step 1020, user input may be received requesting playback of one of the recordings of the television channels. For instance, the user may specify one of the television channels and a time/date for which playback is requested. In some embodiments, the user may select a particular television program which was recorded as part of the channel-specific file for playback. As an example, referring to embodiment 300 of
At step 1030, a playback status element may be presented for one or more of the television channel-specific files recorded at step 1010. In some embodiments the playback status element may only indicate the television channel currently selected for playback (such as embodiment 300 of
At step 1040, playback of the selected television channel and/or selected television program may be played back from one of the television channel-specific files recorded at step 1010. When a television program that is part of the channel-specific file being played back has completed according to the corresponding bookmark file created at step 1015, method 1000 may proceed to step 1050 or step 1060, depending on the embodiment. At step 1050, when the television program has completed playback, the next television program within the same channel-specific file may commence playback. The playback status element may be displayed for a predefined period of time when such playback begins. The next television program may correspond to the television program that was broadcast (and thus recorded) immediately following the television program that was played back at step 1040. Embodiments of method 1000 may proceed to step 1050 when a channel-specific file is selected for playback rather than a specific television program from within the channel-specific file being selected for playback.
In some embodiments, method 1000 may proceed to step 1060 from step 1040. At step 1060, when playback of the first television program played back at step 1040 is complete, an event status may be presented to the user. For example, an event status such as in embodiments 700 and 800 of
At step 1070, user input indicating the selected option may be received. Such input may be received from a remote control or some other form of input device by the television receiver. At step 1075, the user input is analyzed to determine if, for example, the user has indicated that the next television program recorded as part of the channel-specific file is to be played back. If the first television program played back at step 1040 was the last recorded television program within the channel-specific file, the option of continued playback may not be available to the user (or the option may switch to a channel-specific file for the same channel from a different date or a channel-specific file for a different channel). If the user selects continued playback of the channel-specific file, at step 1080 the second television program may be played back. This second television program may have been recorded as part of the channel-specific file at step 1010 on the same television channel as the first channel when the first television program was completed being broadcast.
At step 1075, if a user indicates that playback of the next recorded television program within the channel-specific file is not to occur, method 1000 may proceed to step 1090. At step 1090, some other action may be performed, such as returning to a DVR menu.

In some cases, the storage medium might be incorporated within a computer system, such as computer system 1100. In other embodiments, the storage medium might be separate from a computer system (e.g., a removable medium, such as a compact disc), and/or provided in an installation package, such that the storage medium can be used to program, configure, and/or adapt a general purpose computer with the instructions/code stored thereon. These instructions might take the form of executable code, which is executable by the computer system 1100 and/or might take the form of source and/or installable code, which, upon compilation and/or installation on the computer system 1100 (e.g., using any of a variety of generally available compilers, installation programs, compression/decompression utilities, etc.), then takes the form of executable code.
It will be apparent to those skilled in the art that substantial variations may be made in accordance with specific requirements. For example, customized hardware might also be used, and/or particular elements might be implemented in hardware, software (including portable software, such as applets, etc.), or both. Further, connection to other computing devices such as network input/output devices may be employed.
As mentioned above, in one aspect, some embodiments may employ a computer system (such as the computer system 1100) to perform methods in accordance with various embodiments of the invention. According to a set of embodiments, some or all of the procedures of such methods are performed by the computer system 1100 in response to processor 1110 executing one or more sequences of one or more instructions (which might be incorporated into the operating system 1140 and/or other code, such as an application program 1145) contained in the working memory 1135. Such instructions may be read into the working memory 1135 from another computer-readable medium, such as one or more of the non-transitory storage device(s) 1125. Merely by way of example, execution of the sequences of instructions contained in the working memory 1135 might cause the processor(s) 1110 to perform one or more procedures of the methods described herein.
The terms “machine-readable medium” and “computer-readable medium,” as used herein, refer to any medium that participates in providing data that causes a machine to operate in a specific fashion. In an embodiment implemented using the computer system 1100, various computer-readable media might be involved in providing instructions/code to processor(s) 1110 for execution and/or might be used to store and/or carry such instructions/code. In many implementations, a computer-readable medium is a physical and/or tangible storage medium. Such a medium may take the form of a non-volatile media or volatile media. Non-volatile media include, for example, optical and/or magnetic disks, such as the non-transitory storage device(s) 1125. Volatile media include, without limitation, dynamic memory, such as the working memory 1135.
Common forms of physical and/or tangible computer-readable media include, for example, a floppy disk, a flexible disk, hard disk, magnetic tape, or any other magnetic medium, a CD-ROM, any other optical medium, any other physical medium with patterns of marks, a RAM, a PROM, EPROM, a FLASH-EPROM, any other memory chip or cartridge, or any other medium from which a computer can read instructions and/or code.
Various forms of computer-readable media may be involved in carrying one or more sequences of one or more instructions to the processor(s) 1110 for execution. Merely by way of example, the instructions may initially be carried on a magnetic disk and/or optical disc of a remote computer. A remote computer might load the instructions into its dynamic memory and send the instructions as signals over a transmission medium to be received and/or executed by the computer system 1100.
The communications subsystem 1130 (and/or components thereof) generally will receive signals, and the bus 1105 then might carry the signals (and/or the data, instructions, etc. carried by the signals) to the working memory 1135, from which the processor(s) 1110 retrieves and executes the instructions. The instructions received by the working memory 1135 may optionally be stored on a non-transitory storage device 1125 either before or after execution by the processor(s) 1110.
It should further be understood that the components of computer system 1100 can be distributed across a network. For example, some processing may be performed in one location using a first processor while other processing may be performed by another processor remote from the first processor. Other components of computer system 1100 may be similarly distributed.
The methods, systems, and devices discussed above are examples. Various configurations may omit, substitute, or add various procedures or components as appropriate. For instance, in alternative configurations, the methods may be performed in an order different from that described, and/or various stages may be added, omitted, and/or combined. Also, features described with respect to certain configurations may be combined in various other configurations. Different aspects and elements of the configurations may be combined in a similar manner. Also, technology evolves and, thus, many of the elements are examples and do not limit the scope of the disclosure or claims.
Specific details are given in the description to provide a thorough understanding of example configurations (including implementations). However, configurations may be practiced without these specific details. For example, well-known circuits, processes, algorithms, structures, and techniques have been shown without unnecessary detail in order to avoid obscuring the configurations. This description provides example configurations only, and does not limit the scope, applicability, or configurations of the claims. Rather, the preceding description of the configurations will provide those skilled in the art with an enabling description for implementing described techniques. Various changes may be made in the function and arrangement of elements without departing from the spirit or scope of the disclosure.
Also, configurations may be described as a process which is depicted as a flow diagram or block diagram. Although each may describe the operations as a sequential process, many of the operations can be performed in parallel or concurrently. In addition, the order of the operations may be rearranged. A process may have additional steps not included in the figure. Furthermore, examples of the methods may be implemented by hardware, software, firmware, middleware, microcode, hardware description languages, or any combination thereof. When implemented in software, firmware, middleware, or microcode, the program code or code segments to perform the necessary tasks may be stored in a non-transitory computer-readable medium such as a storage medium. Processors may perform the described tasks.
Having described several example configurations, various modifications, alternative constructions, and equivalents may be used without departing from the spirit of the disclosure. For example, the above elements may be components of a larger system, wherein other rules may take precedence over or otherwise modify the application of the invention. Also, a number of steps may be undertaken before, during, or after the above elements are considered. Accordingly, the above description does not bind the scope of the claims.
This application is a continuation of U.S. patent application Ser. No. 13/795,914, filed Mar. 12, 2013, entitled “Multi-Program Playback Status Display,” , which claims priority to U.S. provisional application 61/611,483, filed Mar. 15, 2012, entitled “Reception, Recording, Storage, and Manipulation of Multiple Television Channels,” the entire disclosure of which is hereby incorporated by reference for all purposes.
