Embodiments of the invention generally relate to digital video recorders (DVRs). Embodiments of the invention relate more specifically to techniques for automatically transmitting a DVR user's contact information to an interested party so that the interested party can contact the DVR user.
The approaches described in this section could be pursued, but are not necessarily approaches that have been previously conceived or pursued. Therefore, unless otherwise indicated herein, the approaches described in this section are not necessarily prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.
As used herein, a “program” is any content, visual and/or audible, that is presented through a television's display and/or speakers. For example, a program might be an episode of a multi-episode series, a movie, a sporting event, or a news presentation, although this is not an exclusive list of “programs.” When a digital video recorder (“DVR”) schedules a program for future recording, the DVR attempts to add the program to a “to do” list that the DVR maintains within the DVR's own storage mechanisms. Whenever a program on the DVR's “to do” list is broadcasted, the DVR automatically records that program.
Often, a person will be watching a program or advertisement on his television, when he will see something about which he is interested in obtaining more information. The person might even see something that he would like to purchase. However, often, the person will not have any notion about how to obtain more information (or purchase) the thing that he saw on his television. The program or advertisement might only mention a product, but might give no indication about where or how to buy that product, for example.
Sometimes, a program or advertisement will display a phone number that the person can call in order to obtain more information or purchase a product. However, some people might be too lazy, or too involved in the program that they are watching, to move to the telephone (which might not be located near to the television) and dial the displayed telephone number. Some people find telephone numbers difficult to remember, and might forget what number they were supposed to dial by the time they have the opportunity to place a telephone call.
As a result, the person often ends up not obtaining the information or product in which he was interested, and the supplier of the information or product potentially loses the person's business, from which the supplier otherwise might have benefited.
The present invention is illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings and in which like reference numerals refer to similar elements and in which:
A method and apparatus for scheduling the recording of upcoming programs, and for extending the duration of the time interval during which those programs will be recorded, is described. In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the present invention.
Embodiments are described herein according to the following outline:
The needs identified in the foregoing Background, and other needs and objects that will become apparent for the following description, are achieved in the present invention, which comprises, in one aspect, a technique whereby a DVR sends a DVR user's contact information (e.g., name, telephone number, street address, e-mail address, etc.) over a network (e.g. the Internet) to a supplier of products, a supplier of services, and/or a supplier of information.
In one embodiment of the invention, the DVR prompts the DVR user (e.g., the DVR's owner) to enter contact information for the DVR user. The contact information may include, among other items of information, the DVR user's name, one or more of the DVR user's telephone numbers, the DVR user's home street address (i.e., the address at which the DVR user lives), the DVR user's shipping address (if different from the DVR user's home street address), and/or other information about the DVR user. In response to the DVR's prompt, the DVR user supplies the requested contact information to the DVR. For example, the user might supply the contact information to the DVR via buttons on a DVR remote control and an on-screen representation of selectable numbers, letters, and other characters which the contact information might comprise. After the DVR user has supplied the requested contact information to the DVR, the DVR stores the contact information on the DVR's hard disk drive or other persistent storage mechanism.
According to one embodiment of the invention, a broadcaster of television programs (e.g., via cable or via satellite signals) or some other party includes, encoded (e.g., in a closed-captioning stream) within a television program or advertisement, a “tag” or other code or signal that the DVR is capable of understanding. The tag is of a kind that indicates to the DVR that an interested party would like to receive the DVR user's contact information. Additional information on tags that may be contained in, or broadcasted in conjunction with, television programs or advertisements, is described in U.S. patent application Ser. No. 09/665,921, titled “CLOSED CAPTION TAGGING SYSTEM,” and in U.S. patent application Ser. No. 11/473,543, titled “IN-BAND DATA RECOGNITION AND SYNCHRONIZATION SYSTEM.” Both U.S. patent application Ser. No. 09/665,921 and U.S. patent application Ser. No. 11/473,543 are incorporated by reference for all purposes as though fully disclosed herein. In one embodiment of the invention, the tag is a specified, DVR-recognized code that is contained in the closed-captioning stream that accompanies the television program or commercial; the tag may be embedded in the vertical blanking interval (VBI) of an analog signal, or in a private data channel in an MPEG2 multiplex. Although in one embodiment of the invention, the tag is expressly inserted into the closed-captioning stream (in addition to other text that is already contained in that stream), in an alternative embodiment of the invention, the tag is derived by inputting portions of the usual contents of the closed-captioning stream into a hash function, which produces hash codes, at least some of which represent tags. In such an alternative embodiment of the invention, there is no need to insert tags into the closed-captioning stream; instead, the tags are derived from text that is already contained in that stream. In yet another embodiment of the invention, tags can be derived from information that is contained in the frames of the video content itself, and/or from the audio that accompanies the video content. Such video and/or audio data can similarly be passed through a hash function to derive hash codes, at least some of which can be mapped to tags with specified characteristics. In one embodiment of the invention, the tag also identifies a universal resource locator (“URL”) and/or e-mail address of a supplier of information, services, and/or products (e.g., the information, services, or products that are featured in the television program or advertisement that contains the tag). In such an embodiment of the invention, upon determining that a television program or advertisement contains such a tag, the DVR displays, to the DVR user, an icon and/or verbal prompt that invites the DVR user to allow the DVR to send the DVR user's contact information to the supplier. For example, the DVR may display such an icon and/or prompt in an overlay in a portion of the television screen in a manner that does not interfere significantly with the television program or advertisement that is currently being displayed; in this manner, the DVR may display the icon and/or prompt without interrupting the DVR user's viewing experience. The DVR's display of the icon and/or prompt may be accompanied by the DVR audibly playing a tone that helps to alert the DVR user as to the current presence of the icon and/or prompt.
According to one embodiment of the invention, in response to the DVR's display of the icon and/or prompt described above, the DVR user is given the opportunity to either (a) permit the DVR to send the DVR user's contact information to the supplier or (b) refuse to permit the DVR to send the DVR user's contact information to the supplier. The DVR may receive input from the DVR user via the DVR remote control, for example. If the DVR user indicates, via the input, a refusal to allow the DVR user's contact information to be sent, then the DVR prevents the DVR user's contact information from being accessed by the supplier (by not sending the DVR user's contact information to the supplier).
Alternatively, if the DVR user indicates, via the input, permission for the DVR to send the DVR user's contact information to the supplier, then, in one embodiment of the invention, the DVR reads the DVR user's contact information from the DVR's hard disk drive or other persistent storage device and sends the DVR user's contact information to the URL and/or e-mail address that is indicated in or otherwise associated with the tag that is encoded in the television program or advertisement. In one embodiment of the invention, the DVR sends such information over the Internet, initially through an Ethernet port or wireless communication interface through which the DVR is communicatively coupled to the Internet.
In one embodiment of the invention, when the DVR sends the DVR user's contact information to the supplier's URL and/or e-mail address, a person or automated mechanism at the supplier's end receives the DVR user's contact information and takes some responsive action. For example, the person or mechanism may initiate a telephone call to one or more of the telephone numbers that are specified in the DVR user's contact information. During such a call, the person or mechanism might provide additional information to the DVR user about a product or service that was featured in the television program or advertisement. Additionally or alternatively, during such a call, the person or mechanism might invite the DVR user to purchase a product or service that was featured in the television program or advertisement. For another example, the person or mechanism might send, over the Internet, an e-mail message to one or more of the DVR user's e-mail addresses that are specified in the DVR user's contact information. For yet another example, the person or mechanism might send, over the Internet, to the DVR, one or more instructions which cause the DVR to display information to the DVR user on the television screen, and/or which cause the DVR to request additional information from the DVR user via a DVR-generated and displayed user interface and the DVR remote control.
As a result of the foregoing techniques, DVR users are able to obtain information about products and services that those DVR users see on television without being troubled with obtaining or remembering specific details about how to obtain that information. In one embodiment of the invention, inviting a supplier to contact the DVR user can be achieved simply through the DVR user's pressing of a button on the DVR remote control. Thus, the DVR user does not need to scramble to write down a telephone number or look up information about a product or service that he saw. The DVR user does not need to interrupt his television viewing experience to find a telephone and dial a number (which many DVR users might be loathe to do). The foregoing techniques potentially benefit suppliers and advertisers of information, products, and services, who otherwise might miss out on business opportunities that are made possible from the DVR's provision of DVR users' contact information to those suppliers and advertisers.
In other aspects, embodiments of the invention encompass a computer apparatus and a computer-readable storage medium configured to carry out the foregoing technique.
Personal computer 208 may be a personal computing device, such as a desktop computer or laptop computer, and is also coupled to network 205 through any communications interface, including wireless. Portable device 210 may be any handheld computing device, cellular phone, portable media player, or any other portable device capable of displaying multimedia content and may be coupled to network 205 through any communications interface, including wireless. DVR 202, personal computer 208, and portable device 210 each communicate with service provider 204 through network 205. In another embodiment, DVR 202, personal computer 208, and portable device 210 each communicate with content provider 210 through network 205.
Network 205 may be implemented by any medium or mechanism that provides for the exchange of data between devices in the communication system. Examples of network 205 include, without limitation, a network such as a Local Area Network (LAN), Wide Area Network (WAN), the Internet, one or more terrestrial, satellite or wireless links, etc. Alternatively or additionally, any number of devices connected to network 205 may also be directly connected to each other through a communications link.
In one embodiment, content provider 206 provides broadcast program content to DVR 202 via cable, satellite, terrestrial communication, or other transmission method. Broadcast program content may include any multimedia content such as: audio, image, or video content. In another embodiment, content provider 206 provides multimedia content, such as any downloadable content, through network 205 to DVR 202, personal computer 208, or portable device 210.
In one embodiment, DVR 202 communicates with service provider 204, which provides program guide data, graphical resources (such as fonts, pictures, etc.), service information, software, advertisements, event identification data, and other forms of data enable DVR 202 to operate independently of service provider 204 to satisfy user interests. In another embodiment, DVR 202, personal computer 208, and portable device 210 can communicate with each other to transfer content, metadata, or any other data through network 205, communication connection, or any local network.
In another embodiment, content provider 206 may provide, to service provider 204, content data or any metadata, including promotional data, icons, web data, and other information. Service provider 204 may then interpret the metadata and provide the content data metadata to DVR 202, personal computer 208, or portable device 210.
Referring to
DVR 202 receives broadcast signals from an antenna, from a cable TV system, satellite receiver, etc., via input 252A. Input 252A may comprise a plurality of tuning modules that allow a plurality of signals to be received and recorded simultaneously. For example, a TV input stream received by input 252A may take the form of a National Television Standards Committee (NTSC) compliant signal or a PAL compliant broadcast signal. For another example, a TV input stream received by input 252A may take a digital form such as a Digital Satellite System (DSS) compliant signal, a Digital Broadcast Services (DBS) compliant signal, or an Advanced Television Standards Committee (ATSC) compliant signal. DBS, DSS, and ATSC are based on standards called Moving Pictures Experts Group 2 (MPEG-2) and MPEG-2 Transport. MPEG-2 Transport is a standard for formatting the digital data stream from the TV source transmitter so that a TV receiver can disassemble the input stream to find programs in the multiplexed signal.
An MPEG-2 transport multiplex supports multiple programs in the same broadcast channel with multiple video and audio feeds and private data. Input 252A tunes to a particular program in a channel, extracts a specified MPEG stream from the channel, and feeds the MPEG stream to the rest of the system. Analog TV signals are encoded into a similar MPEG format using separate video and audio encoders, such that the remainder of the system is unaware of how the signal was obtained. Information may be modulated into the vertical blanking interval (VBI) of the analog TV signal in a number of standard ways; for example, the North American Broadcast Teletext Standard (NABTS) may be used to modulate information onto certain lines of an NTSC signal, which the FCC mandates the use of a certain other line for closed caption (CC) and extended data services (EDS). Such signals are decoded by input 252A and passed to the other modules as if the signals had been delivered via an MPEG-2 private data channel.
Recording Module 260 records the incoming data stream by storing the digital data stream on at least one storage facility, signified by Storage 264A/264B that is designed to retain segments of the digital data stream. Storage 264A/264B may be one or more non-volatile storage devices (e.g., hard disk, solid state drive, USB external hard drive, USB external memory stick, USB external solid state drive, network accessible storage device, etc.) that are internal 264A and/or external 264B. A Signal Converter 254 retrieves segments of the data stream, convert the data stream into an analog signal, and then modulate the signal onto a RF carrier, via Output 252B, through which the signal is delivered to a standard TV set. Output 252B may alternatively deliver a digital signal to a TV set or video monitor. For example, DVR 202 may utilize a Digital Visual Interface port (DVI) for sending digital signals to a TV via a DVI cable.
DVR 202 also includes a Communication Interface 262, through which the DVR 202 communicates with Network 205 via Ethernet, wireless network, modem, or other communications standard. Further, DVR 202 may be integrated into a TV system such that the components described above are housed in a TV set capable of performing the functions of each component of DVR 202.
In another embodiment, DVR 202 generally comprises a plurality of components necessary to receive, record, store, transfer and playback digital data signals from a plurality of sources, such as a PC, a DVR, a service provider, or content server. DVR 202 can transfer digital data signals to another DVR or PC. DVR 202 may encode or decode digital signals via Encoder 256A and Decoder 256B into a plurality of formats for playback, storage or transfer. According to one embodiment of the invention, encoder 256A produces MPEG streams. According to another embodiment of the invention, encoder 256A produces streams that are encoded using a different codec. Decoder 256B decodes the streams encoded by encoder 256A or streams that are stored in the format in which the streams were received using an appropriate decoder. DVR 202 can also encrypt or decrypt digital data signals using Encryptor/Decryptor 258 for storage, transfer or playback of the digital data signals.
In one embodiment, DVR 202 communicates with Service Provider 204, which provides program guide data, graphical resources such as brand icons and pictures, service information, software programs, advertisements, and other forms of data that enable DVR 202 to operate independently of the Service Provider 204 to perform autonomous recording functions. Communication between DVR 202 and Service Provider 204 utilizes a secure distribution architecture to transfer data between the DVR 202 and the Service Provider 204 such that both the service data and the user's privacy are protected.
Referring now to
The DVR may request the contact information initially the first time that the DVR is powered on. Additionally or alternatively, the DVR may request the contact information as part of a process whereby the DVR user subscribes to a DVR service agreement (DVR users are typically required to subscribe to some service so that their DVRs can obtain electronic programming guide information that the DVRs need in order to determine the dates, times, and channels on which programs are going to be broadcasted). In one embodiment of the invention, the DVR user can opt in or opt out of having the DVR use the user's personal information automatically whenever a contact information request is displayed. In one embodiment of the invention, the DVR does not request the contact information until the contact information is needed (e.g., later in the process described below), and then only if the contact information has not yet been stored on the DVR's hard disk drive or other persistent storage device.
In block 104, the DVR receives the DVR user's contact information from the DVR user. For example, the DVR may receive the DVR user's contact information through a DVR-generated and displayed user interface as described above. Alternatively, the DVR may automatically retrieve the DVR user's contact information from a DVR service provider. In one embodiment of the invention, multiple different user profiles are stored on the DVR, and different user contact information is received for and associated with each user profile; the current user can select which of the several user profiles is active at any particular time. In one embodiment of the invention, each user of the DVR has a different remote control, which may be programmed to send, to the DVR, a user identifier that is associated only with that remote control. Each user identifier may be associated with a different user profile and different user contact information. In such an embodiment of the invention, the DVR stores the received user contact information with the user profile whose user identifier is sent from the programmed remote control that is currently being used to enter the user contact information.
In block 106, in response to receiving the DVR user's contact information, the DVR persistently stores the DVR user's contact information on the DVR's hard disk drive or other persistent storage device.
In block 108, the DVR detects that a television signal (or other signal, such as a signal that the DVR is receiving over the Internet, or a signal that is contained in DVR-recorded content that the DVR is playing, or a signal that the DVR is receiving from a cable or a satellite dish) that the DVR is receiving contains (or can have derived from it) a code or tag that is of a certain specified type. In response to detecting this code or tag in the signal, the DVR displays a verbal or textual prompt or icon on the television screen. The contents of the prompt may be based on a value that is specified in the tag; thus, the DVR may determine which prompt of several stored prompts is associated with the detected tag, and then fetch the associated prompt from a storage device for display. The verbal or textual prompt or icon informs the DVR user that there is some supplier or other interested party who would like to receive the DVR user's contact information. Typically, this supplier or interested party will be a person, organization, or other entity that is somehow associated with information, products, or services that are represented within a television program or advertisement that the signal represents or with which the signal is associated. As is mentioned above, in one embodiment of the invention, the DVR causes the television to emit an audible sound that indicates, to the DVR user, that the icon or prompt is currently being displayed on the television screen (so that the DVR user is more likely to notice the icon or prompt). In one embodiment of the invention, the prompt is in the form of a question that identifies the requesting supplier or interested party and asks the DVR user whether the DVR has the DVR user's permission to send the DVR user's contact information to the supplier or interested party. The DVR may present the icon and/or prompt in a manner (e.g., in an overlay that is semi-transparent and occupies only a portion of the television screen) that does not significantly intrude upon or interrupt the DVR user's television viewing experience.
In block 110, the DVR receives, from the DVR user, user input that indicates whether the DVR user has granted the DVR permission to send the DVR user's contact information to the supplier or interested party. In one embodiment of the invention, the DVR user supplies this user input by using the buttons on the DVR remote control to select a “YES” button or “NO” button that is displayed in the DVR-generated and displayed user interface. In one embodiment of the invention, the DVR user supplies this user input by pushing either a “YES” button on the DVR remote control or a “NO” button on the DVR remote control. In one embodiment of the invention, if a specified amount of time passes after the time that the DVR causes the icon or prompt to be displayed, and if the DVR has not yet received the user input from the DVR user, then the DVR treats the lack of user input as though the DVR user had selected “NO,” or some other refusal to grant the DVR permission to send the DVR user's contact information. In one embodiment of the invention, the DVR tracks the number of times that a “YES” is selected, and the number of times that a “NO” is selected. In such an embodiment of the invention, the DVR sends this tracking information to the DVR service provider so that the DVR service provider can inform interested advertisers how many users selected “YES,” and how many users selected “NO.” An example of a real-time DVR usage reporting system is described in U.S. patent application Ser. No. 12/190,519, which is titled “REAL-TIME DVR USAGE AND REPORTING SYSTEM,” and which is incorporated by reference for all purposes as though fully disclosed herein.
In block 112, the DVR determines whether the user input indicates that the DVR user has given the DVR permission to send the DVR user's contact information to the supplier or interested party. If the DVR determines that the user input indicates that the DVR user has agreed to allow the DVR to send the contact information, then control passes to block 116. Otherwise, control passes to block 114.
In block 114, in response to the DVR user's denial of permission (or refusal to grant permission) for the DVR to send the contact information, the DVR prevents the DVR user's contact information from being accessed by the supplier or interested party. In one embodiment of the invention, the DVR accomplishes this prevention by refraining from sending the DVR user's contact information to the supplier or interested party. The DVR may remove the icon or prompt from the television screen or monitor and regular program viewing may continue in the same manner as before the icon or prompt was displayed. Control eventually passes back to block 108 when the DVR next detects another tag or code of the specified kind in the television signal (or other signal, such as a signal that the DVR is receiving over the Internet, or a signal that is contained in DVR-recorded content that the DVR is playing, or a signal that the DVR is receiving from a cable or a satellite dish).
Alternatively, in block 116, in response to the DVR user's grant of permission for the DVR to send the contact information, the DVR reads the DVR user's previously stored contact information from the DVR's one or more storage devices, such as a hard disk drive or other persistent device (if that contact information has been stored by this time) and sends the DVR user's contact information over the Internet to a supplier, the service, or interested party that is associated with the tag or code mentioned above. In one embodiment of the invention, the tag or code contains or otherwise specifies a URL, e-mail address, or instant messaging identity of the supplier or interested party. Under such circumstances, the DVR sends the DVR user's contact information (or at least a specified portion thereof) to the URL, e-mail address, or instant messaging identity that is contained in or otherwise specified by the tag or code. In one embodiment of the invention, the DVR sends the DVR user's contact information over the Internet or some other network (e.g., a LAN, a WAN, etc.). In an embodiment in which different programmed remote controls correspond to different user profiles established on the same DVR, the DVR determines which user identifier was received from the programmed remote control from which the user's grant of permission was received, and sends the contact information that is associated with that user identifier.
In one embodiment of the invention, if the DVR determines that the DVR user's contact information has not yet been stored on the DVR's hard disk drive or other persistent storage device by this time, then the DVR requests the DVR user's contact information from the DVR user at this time (e.g., using the techniques described above with reference to blocks 102-104), and stores that contact information on the DVR's hard disk drive or other persistent storage device for current and later use. Thus, in one embodiment of the invention, the first time that the DVR requests and/or receives the DVR user's contact information is the first time that the DVR user agrees to allow the DVR to send the DVR user's contact information to some supplier or interested party. After the DVR has initially stored the DVR user's contact information, the DVR does not need to request the DVR user's contact information from the DVR user again.
In one embodiment of the invention, the supplier or interested party receives the DVR user's contact information over the Internet. In response to receiving this contact information, a person or mechanism at the supplier or interested party's end may initiate contact with the DVR user using the data that is contained within the contact information. For example, the person or mechanism may initiate a telephone call with the DVR user by entering (or, as it used to be called, “dialing”) the person's telephone number (as indicated in the contact information) into the person or mechanism's telephone. For another example, the person or mechanism may send an e-mail message to an e-mail address that is indicated in the contact information. For another example, the person or mechanism may initiate an instant messaging session (e.g., using Yahoo! Instant Messenger) with the instant messaging identity that is indicated in the contact information. An instant messaging application may execute on the DVR itself, thus allowing instant communication with the DVR user, or on a computer that is also owned and/or used by the DVR user. For another example, the person or mechanism may send a letter, DVD, CD, sample, coupon, catalog, and/or other printed or encoded information to a street address that is indicated in the contact information. In one embodiment of the invention, the person or mechanism initiates a voice-over-IP (“VOIP”) session with the DVR user's DVR using data (e.g., an Internet Protocol (IP) address) that is contained in the contact information that the DVR sent over the Internet. The person or mechanism may then communicate with the DVR user over this VOIP session.
Regardless of the communication approach that the person or mechanism uses to initiate communication with the DVR user, the person or mechanism may send a variety of communications to the DVR user. For example, the person or mechanism may send additional information about a product or service that was featured in the television program or advertisement that the DVR user was watching at the time that the DVR asked the DVR user's permission to send the contact information. For another example, the person or mechanism may invite the DVR user to purchase such a service or product. In one embodiment of the invention, the person or mechanism uses credit card or bank information that is contained in the contact information (though, in alternative embodiments of the invention, the contact information may omit such credit card or bank information) to charge the DVR user for a service or product that the DVR user purchases in the communication with the person or mechanism.
Computer system 300 may be coupled via bus 302 to a display 312, such as a cathode ray tube (“CRT”), for displaying information to a computer user. An input device 314, including alphanumeric and other keys, is coupled to bus 302 for communicating information and command selections to processor 304. Another type of user input device is cursor control 316, such as a mouse, trackball, stylus, or cursor direction keys for communicating direction information and command selections to processor 304 and for controlling cursor movement on display 312. This input device typically has two degrees of freedom in two axes, a first axis (e.g., x) and a second axis (e.g., y), that allows the device to specify positions in a plane.
The invention is related to the use of computer system 300 for selecting a frame of a multi-frame video program for display in accordance with a selected trick play mode of a DVR. According to one embodiment of the invention, selecting a frame of a multi-frame video program for display in accordance with a selected trick play mode of a DVR is provided by computer system 300 in response to processor 304 executing one or more sequences of one or more instructions contained in main memory 306. Such instructions may be read into main memory 306 from another computer-readable medium, such as storage device 310. Execution of the sequences of instructions contained in main memory 306 causes processor 304 to perform the process steps described herein. In alternative embodiments, hard-wired circuitry may be used in place of or in combination with software instructions to implement the invention. Thus, embodiments of the invention are not limited to any specific combination of hardware circuitry and software.
The term “computer-readable medium” as used herein refers to any medium that participates in providing instructions to processor 304 for execution. Such a medium may take many forms, including but not limited to, non-volatile media, volatile media, and transmission media. Non-volatile media includes, for example, optical or magnetic disks, such as storage device 310. Volatile media includes dynamic memory, such as main memory 306. Transmission media includes coaxial cables, copper wire and fiber optics, including the wires that comprise bus 302. Transmission media can also take the form of acoustic or light waves, such as those generated during radio wave and infrared data communications.
Common forms of 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, punchcards, papertape, any other physical medium with patterns of holes, a RAM, a PROM, and EPROM, a FLASH-EPROM, or any other memory chip or cartridge.
Various forms of computer readable media may be involved in carrying one or more sequences of one or more instructions to processor 304 for execution. For example, the instructions may initially be carried on a magnetic disk of a remote computer. The remote computer can load the instructions into its dynamic memory and send the instructions over a telephone line using a modem. A modem local to computer system 300 can receive the data on the telephone line and use an infrared transmitter to convert the data to an infrared signal. An infrared detector can receive the data carried in the infrared signal and appropriate circuitry can place the data on bus 302. Bus 302 carries the data to main memory 306, from which processor 304 retrieves and executes the instructions. The instructions received by main memory 306 may optionally be stored on storage device 310 either before or after execution by processor 304.
Computer system 300 also includes a communication interface 318 coupled to bus 302. Communication interface 318 provides a two-way data communication coupling to a network link 320 that is connected to a local network 322. For example, communication interface 318 may be an integrated services digital network (“ISDN”) card or a modem to provide a data communication connection to a corresponding type of telephone line. As another example, communication interface 318 may be a local area network (“LAN”) card to provide a data communication connection to a compatible LAN. Wireless links may also be implemented. In any such implementation, communication interface 318 sends and receives electrical, electromagnetic or optical signals that carry digital data streams representing various types of information.
Network link 320 typically provides data communication through one or more networks to other data devices. For example, network link 320 may provide a connection through local network 322 to a host computer 324 or to data equipment operated by an Internet Service Provider (“ISP”) 326. ISP 326 in turn provides data communication services through the world wide packet data communication network now commonly referred to as the “Internet” 328. Local network 322 and Internet 328 both use electrical, electromagnetic or optical signals that carry digital data streams. The signals through the various networks and the signals on network link 320 and through communication interface 318, which carry the digital data to and from computer system 300, are exemplary forms of carrier waves transporting the information.
Computer system 300 can send messages and receive data, including program code, through the network(s), network link 320 and communication interface 318. In the Internet example, a server 330 might transmit a requested code for an application program through Internet 328, ISP 326, local network 322 and communication interface 318.
The received code may be executed by processor 304 as it is received, and/or stored in storage device 310, or other non-volatile storage for later execution. In this manner, computer system 300 may obtain application code in the form of a carrier wave.
In the foregoing specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
For example, in one embodiment of the invention, after the DVR has supplied the DVR user's contact information to the interested party (e.g., a supplier), as described above, the interested party uses the interested party's computer to initiate a voice-over-IP (“VOIP”) session with the DVR. After such a session has been initiated, the interested party can speak directly to the DVR user via the DVR user's DVR and television set, through VOIP packets transmitted over the Internet. In such an embodiment of the invention, the contact information that the DVR transmits to the interested party includes the DVR's IP address and/or other identifiers that are unique to the DVR, so that the interested party's computer is able to establish the VOIP connection with the DVR over the Internet.
In one such embodiment of the invention, a microphone is connected or built into the DVR, so that the DVR is capable of receiving speech from the DVR user. In such an embodiment of the invention, the DVR transmits, over the VOIP connection, to the interested party's computer, audible speech that the DVR user emits. Thus, in one embodiment of the invention, the DVR user and the interested party have a voice communication with each other without using the DVR user's telephone—the DVR itself performs the voice communications role that the telephone otherwise would.
In a similar embodiment of the invention, the interested party establishes an over-the-Internet video conference between the interested party's computer and the DVR. The interested party and the DVR user communicate with each other in this video conference. The DVR may optionally be connected to or have a built-in video camera and microphone so that the interested party can both see and hear what the DVR user is doing and saying. In such an embodiment of the invention, the interested party's actions and speech can be presented to the DVR user through the screen and speakers of the television to which the DVR is attached.
In a similar embodiment of the invention, the interested party establishes an instant messaging connection between the interested party's computer and the DVR. The interested party and the DVR user communicate with each other in this video conference.
Although embodiments of the invention have been described above with reference to a DVR, alternative embodiments of the invention may be implemented in, and used relative to, devices other than a DVR. For example, in one embodiment of the invention, a portable memory device is used in placed of the DVR discussed above. An example of such a portable memory device, and such a device's other possible applications for transporting content, is described in U.S. patent application Ser. No. 12/191,261, which is titled “CONTENT DISTRIBUTION SYSTEM USING TRANSPORTABLE MEMORY DEVICES,” and which is incorporated by reference for all purposes as though fully disclosed herein. At least some implementations of such a portable memory device do not require the ability to record television programs (e.g., some such devices might retrieve content from the Internet only).
This application claims priority, as a continuation application, to application Ser. No. 15/974,408, filed May 8, 2018 (currently allowed), which is a continuation of application Ser. No. 14/543,433, filed Nov. 17, 2014 now U.S. Pat. No. 9,986,295, issued May 29, 2018, which is a continuation of application Ser. No. 13/871,289 filed Apr. 26, 2013, now U.S. Pat. No. 8,893,180, issued Nov. 18, 2014, which is a continuation of application Ser. No. 12/420,789 filed Apr. 8, 2009, now U.S. Pat. No. 8,438,596, issued May 7, 2013, the entire contents of which is hereby incorporated by reference as if fully set forth herein, under 35 U.S.C. § 120. The applicant(s) hereby rescind any disclaimer of claim scope in the parent application(s) or the prosecution history thereof and advise the USPTO that the claims in this application may be broader than any claim in the parent application(s).
