Abstract
Channel information is displayed for a user in improved fashion by adjusting the amount of information according to the rate with which the user previews channels. For example, at a first rate of preview, the channel number, channel logo, program name and video could be displayed for each previewed channel, while at a faster rate, the channel number and logo could be displayed, and at a still faster rate the channel number alone could be displayed for each previewed channel. The rate of preview can be dictated by remote control signals, such as those produced by a remote control jog dial. The user can rotate the jog dial to preview channels at various rates and receive corresponding amounts of information for each previewed channel dependent upon the rate that the channels are previewed.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This application relates to varying the amount of information provided for previewed channels according to the rate with which channels are previewed.




2. Description of the Related Art




Home entertainment continues to change at a rapid pace, with ever increasing content becoming seemingly available. For example, cable or satellite broadcasting system viewers may now expect to select programming from among hundreds of available channels. Also, the convergence of computer network architectures and traditional broadcast entertainment promises to further increase the availability of information.




Typically, a user may preview available channels in sequential fashion, or may manually jump to a given channel, with each previewed channel occupying the entirety of the display. Various electronic program guides (EPGs), such as those provided in a cable television system or satellite system, have also become available to preview channels. Specifically, EPGs typically provide textual programming information about available channels. Many EPGs display a grid detailing certain programming information for the channels available for viewing. The columns in the grid may represent various programming times, while the rows in the grid may represent various available channels. The intersection of rows representing the available channels with the column for a given time provides the programming information for that time.




While conventional EPGs have been helpful in compiling programming information, they may be inadequate interfaces for users navigating numerous channels, and do not provide the amount of information that a user may wish to receive.




SUMMARY OF THE INVENTION




In accordance with the present invention, methods and apparatus vary the amount of information corresponding to previewed channels dependent upon the rate that the user previews the channels. Generally, when the user previews available channels at a relatively slow rate, more information is displayed for each previewed channel, but at relatively faster channel preview rates, progressively less information is displayed. This allows that user to rapidly scan available channels, and to slow the preview rate for more information where interesting programming appears to be present.




In one embodiment, a jog dial on a remote control provides the control signals that determine the rate for previewing channels. The determined channel preview rate dictates the amount of information provided for each previewed channel. Rotating the jog dial can increase the preview rate, with various rates and corresponding amounts of information corresponding to various jog dial positions. The information provided for each previewed channel ranges from a relatively high amount (e.g., channel number, logo, program name, video and audio) for the slowest channel preview rate, to a relatively low amount (e.g., channel number only) for the fastest channel preview rate. Using the jog dial allows the user to focus on the display, and to alter the channel previewing rate and corresponding programming information without having to focus on the remote control buttons.

DETAILED DESCRIPTION OF THE INVENTION




Certain embodiments of the present invention described herein may be used with a direct broadcast satellite system. However, the ordinarily skilled artisan will recognize that other broadcast systems and formats, including without limitation cable and terrestrial systems, digital televisions, computer systems, and combinations of all such systems may utilize the method and apparatus of the present invention. Furthermore, in the following description, for purposes of explanation, numerous details are set forth, such as flowcharts and system configurations, in order to provide an understanding of an embodiment of the present invention. However, it will be apparent to one skilled in the art that these specific details are not required in order to practice the present invention.





FIG. 1

is a schematic diagram illustrating a Direct Satellite System (DSS), which is an example of a system that may be used in conjunction with the present invention. The system has an antenna


3


, an IRD (Integrated Receiver/Decoder)


2


, a remote control


5


, and a display device


4


. Signals are transmitted by a satellite transponder and received by the antenna


3


. The IRD


2


also includes circuitry for decoding the signals received by the antenna


3


, and for appropriately tuning or filtering signals so as to provide a display output according to user's selections and desires. Typically, the satellite transponder transmits packetized data in a time shared manner at a predetermined frequency. The IRD


2


receives the packetized data through the antenna


3


, and then demodulates and decodes the data to produce signals appropriate for producing display


4




a.






The IRD


2


may also be referred to as a set top box. Also, the functionality of the IRD


2


may be provided within the television housing. The IRD


2


may also be an open configuration that allows receipt from various programming sources (e.g., cable, satellite, to conventional television, HDTV, etc.).




The block diagram of

FIG. 2

illustrates an embodiment of an IRD


2


in further detail. As described above, the antenna


3


receives an encoded data signal sent from a satellite. The antenna


3


has a low noise block down converter


3




a


(LNB), which converts a frequency of a signal sent from the satellite to another frequency. This signal is decoded by the IRD


2


. For IRD


2


embodiments receiving programming from other sources, other appropriate front end circuitry would be provided, such as a network interface for Internet sources, or an NTSC decoder for conventional television.




The IRD


2


includes a front end


20


having a tuner


21


, quadrature phase shift keying (QPSK) demodulation circuit


22


, and an error correcting circuit


23


. A radio frequency (RF) signal output from the LNB


3




a


is supplied to the tuner


21


, the tuner


21


output is supplied to the QPSK demodulation circuit


22


for demodulation, and the QPSK demodulation circuit


22


output is suppled to the error correcting circuit


23


for error correction.




The received data is an encoded packetized data stream that is passed to an AV processing module


40


that includes a demultiplexer


42


, video decoder


43


, audio decoder


45


, graphics processing module


44


and D/A converter


46


. The AV processing module


40


is in communication with AV memory


31


and EPG/Graphics memory


32


, as well as the CPU


30


. The demultiplexer


42


receives the packets of data from the error correcting circuit


23


and directs portions of the data stream as appropriate for processing, buffering data in the AV memory


31


or EPG/Graphics memory


32


as needed. Typically, the multiplexer


42


uses header information provided in the data stream to identify different types of data. For example, the header distinguishes which packets comprise video, audio and EPG data. Data that is identified as video data is provided to the video decoder


43


, audio data to the audio decoder


45


, and EPG data to the EPG/Graphics memory


32


. The data format can be that specified by the Motion Pictures Expert Group (MPEG), including MPEG2 and MPEG4. Various conventional MPEG data parsing circuitry or software can be used for the demultiplexer


42


, and conventional decoding techniques can be used for the decoders


43


,


45


.




The video decoder


43


decodes the video signal received from the demultiplexer


42


. Also, as indicated, AV memory


31


may buffer video data during processing by the video decoder


43


. The decoded signal is provided to the graphics processing module


44


, which converts the signal to the format required for the display


4


. For example, the graphics processing module may include a National Television System Committee (NTSC) encoder for conversion to luminance (Y) and chroma (C) signals which can be output through buffer amplifiers (not shown) as an S video signal. The graphics processing module


44


also provides graphics overlays, such as those provided when displaying an EPG over a video image, and also may provide a cursor layer for facilitating the receipt of cursor based input. For example, the graphics processing module


44


may access EPG data in the EPG/graphics memory


32


and display such data over a video image for a currently tuned channel, or may display such data over another graphical layer. Additionally, the graphics processing module


44


may grab still frames for currently tuned channels, store them in the EPG/Graphics memory


32


, and later display the still frames along with the video for a subsequently previewed channel as provided in certain embodiments of the present invention, described further below. Conventional pixel mixing circuitry or software may be used for displaying the various image and graphics layers.




The audio decoder


45


decodes the digital audio signal, and the AV memory


31


may buffer data for processing by the audio decoder


45


. The decoded digital audio signal is converted into an analog audio signal by D/A converter


46


, and output through one or more amplifiers (not shown).




The various components of the AV processing module


40


are preferably provided as software executed by the CPU


30


. However, the AV processing module


40


may be software, hardware, firmware, or any combination thereof. Also, in lieu of sole CPU


30


instruction execution, the AV processing module


40


(or any module in the IRD


2


) may be a separate integrated circuit, and may have separate processing capabilities, such as those provided by an embedded RISC processor.




The CPU


30


executes instructions and uses data to provide functionality including the channel preview functionality of the present invention. Instructions to be executed by the CPU


30


are stored in ROM


37


and memory


36


; however, such code may alternatively be stored in other types of memory. The CPU


30


also accesses data such as that stored in memory


36


and electrically erasable programmable read-only memory (EEPROM)


38


, and processes user input received via the front panel


63


and the photodetector circuit


64


. For example, the CPU


30


accesses user settings and preferences for processing information and configuring the system. The user settings may be stored in non-volatile memory, such as EEPROM


38


, so that they are retained when power to the system is interrupted. The EEPROM


38


may also be updated to provide new IRD


2


control programs. A hard disk (not shown) may also be used to store data and code as needed.




Preferably, the CPU


30


maintains a list of pointers stored in memory


36


for the programming information stored in the EPG/Graphics memory


32


(although various memories


31


,


32


,


36


are shown to be separate, they can reside in a single memory if desired). Thus, when the user requests the display of an EPG on the screen or a switch between a broadcast and an EPG, the CPU


30


as instructed by the graphics processing module


44


accesses the pointers stored in the memory


36


, the corresponding EPG data stored in the EPG/Graphics memory


32


, and formats the EPG data to appropriately update the display. Some EPG data, such as that used to provide the look of the EPG, may originate in IRD


2


while other EPG data, such as the content portion may originate from the data transmitted to the IRD


2


as described above. Alternatively, all of the EPG data may originate in the data transmitted to the IRD


2


, or may originate from any source.





FIG. 3

shows an example of a remote control


300


which allows the user to transmit control signals to the IRD


2


. The remote control


300


may also be referred to as a remote controller, or a REMOTE COMMANDER. The remote control


300


has an infrared transmitting device


305


, and various control buttons


310


-


324


for providing corresponding signals to be transmitted to the IRD


2


. Specifically, the remote control


300


includes power buttons


310


to turn on devices for cable


310




a


, terrestrial broadcast television (TV)


310




b


, and satellite


310




c


programming. Alternatively, as described previously a single IRD


2


or set top box could service the various origins of programming, in which case a remote control


300


would likely not include separate power buttons.




Function buttons


312


allow the remote control


300


to alternately control the receivers for cable


312




a


, TV


312




b


or satellite


312




c


. Additionally, the numeric buttons


314


allow manual entry of channel numbers, the channel button


324


allows the user to sequentially navigate among channels, and the volume button


322


allows the user to adjust the audio volume. The guide button


316


allows the user to enter a programming guide mode, while the exit button


318


may be used to exit the programming guide for a return to the viewing mode. A favorite button


326


allows the user to enter a mode wherein a selected subset of available channels may be previewed or otherwise manipulated by the user. These channels may be selected using conventional menus and corresponding commands, using the illustrated control buttons, or other conventional menu and related control buttons (not shown).




The jog dial


320


is a rotating control button that allows the user to provide various control signals. The jog dial


320


rotates both clockwise and counterclockwise, and has a position indicator


320




a


which resides on the rotating dial and indicates the current position of the dial along with stationary markings (O, B


1


-B


3


, A


1


-A


3


). The default or rest position is typically that shown in

FIG. 3

, where the indicator


320




a


points to position “O”. The user may also rotate the jog dial


320


counter-clockwise such that the indicator


320




a


points to position A


1


, then A


2


, then A


3


, or clockwise such that the indicator


320




a


points to position B


1


, then B


2


, then B


3


. When used in connection with this embodiment of the present invention, these different jog dial positions


320




a


can provide control signals-which dictate the direction and rate for previewing channels, as well as the amount of information provided for previewed channels, as is described further below.




Although a jog dial


320


is described as the control mechanism for variously controlling the channel preview rate and corresponding amount of provided information, the artisan will recognize that alternative input devices may be used. For example, a channel button


324


may have various input levels such that degrees of depression of the “+” or “−” portion of the channel button


324


may provide various control signals similar to the jog dial


320


levels, with the “+” side emulating positions A


1


-A


3


and the “−” side emulating B


1


-B


3


. Alternatively, various discrete buttons (not shown) may be used to provide similar controls. Alternatively, the time interval between receipt of a signal requesting the current and next previewed channel may be used to determine the preview rate (i.e., in lieu of direct determination by control signal, time is used to calculate the channel preview rate).





FIG. 4

is a schematic diagram illustrating EPG data, which is an example of some of the channel information that can be displayed in accordance with the present invention. The shown EPG data includes guide data, channel identification data, and program data. The guide data is general information, such as the current date and time. Additional information, such as transponder identification information, channel list, and segment information may also be included in the guide data. The channel identification data includes data relating to channels, such as the channel number, channel name (i.e., the call sign of a broadcast station), logo ID (i.e., an identification of the channel logo), data ID, which is an identification of a channel number of MPEG video data or MPEG audio data, number of programs, which identifies the number of programs to be transmitted on a channel during a predetermined time frame, and first program offset which identifies the offset from the header to the first channel data in a segment.




The program data includes the program title, start time of the program, time length of the program, program category such as movies, news, sports, etc., program subcategory such as drama, horror, children's for the movies category, or baseball, basketball, football for the sports category, the program rating and a program description that provides a detailed description of the program. The various program entries for each channel (e.g.,


1


-


1


through


1


-


8


) may be provided in the sequence with which they are to be shown, or in any desired fashion.




Referring now to the block diagram of

FIG. 5

, an embodiment of a channel preview module


500


is shown to reside within the memory


36


of the IRD


2


, and to include a preview rate module


502


, channel information module


504


, channel index module


506


, and preview display module


508


. The channel preview module


500


receives control signals originated from the remote control, and in response to such control signals causes the display to be updated with programming information such as the EPG data, or other channel information such as video and audio for previewed channels, channel logos, and the like. Generally, the preview rate module


502


receives control signals and determines the current rate for previewing channels, and provides the channel preview rate for the channel information module


504


, which determines the level of detail for previewed channels dependent upon that rate. The channel index module


506


maintains the list of channels being previewed, which may comprise all available channels, or a subset of the available channels such as favorite channels or predetermined subsets (e.g., preset categories), and the preview display module


508


provides the display configuration for previewing channels.




Preferably, the channel preview module


500


, and its modules


502


-


508


are provided as software, although they may alternatively be provided as hardware, firmware, or any combination of software, hardware and firmware. The CPU


30


executes the instructions provided in the channel preview module


500


to provide the variable channel information functionality in accordance with the present invention.




Referring now to the flow chart of

FIG. 6

along with the block diagram of

FIG. 5

, an embodiment of a method


600


for displaying channel information in accordance with the present invention is now further described. In step


602


, a preview signal is received by the channel preview module


500


. The preview signal may result from various controls, such as when the user hits the guide button (


316


, FIG.


3


), or simply when the user manipulates the jog dial out of the O position. When the preview signal is received, channel information for numerous channels is displayed for the user. Preferably, channel information is provided using a sequential arrangement of channel locations such as shown in

FIGS. 8A-8C

, which will be described further below. Of course, embodiments of the present invention can use alternative displays such as a grid having cells with to channel preview rate dependent amounts of information, or various other configurations as desired.




In step


604


, the channel preview rate is determined by the preview rate module


502


. Preferably, the channel preview rate can be discretely provided in the form of control signals provided to the IRD


2


dependent upon the various positions of the remote control jog dial (


320


, FIG.


3


). Thus, first, second and third channel preview rates (which may be referred to as slow, medium and fast) for previewing channels can be directly signaled by the user through appropriate rotation of the jog dial. Alternatively, as described above, the channel preview rate can be provided in the form of control signals produced responsive to buttons, or the degree of depression or pressure that the user applies to the “+” or “−” of the channel switch, or can be calculated from the time interval between the user's selection of the current and next previewed channel.




The artisan will recognize the various alternatives for signaling and determining the channel preview rate. For example, the number of different channel preview rates may vary (e.g. two or four forward and reverse channel preview rates, in lieu of three). Additionally, the actual rate with which a previewed channel is updated from the current to the next previewed channel can vary dependent upon the ability to update the display, which in turn depends upon how much programming information will be included at the current channel preview rate. The actual rate may vary dependent upon the configuration of the system, which can be predetermined or reconfigured by the user as desired. Thus, the step


604


of determining the channel preview rate can rely on calculation or the like, receipt of signals which directly indicate the various rates, or various other alternatives.




Once the channel preview rate is determined, channel information for the currently previewed channel is displayed (step


608


). The amount of provided channel information depends upon the determined channel preview rate. Generally, the level of detail is inversely proportional to the channel preview rate. That is, the most channel information is provided at the slowest channel preview rate, whereas the least programming information (e.g., only the channel number) is provided at the fastest channel preview rate. This optimizes the amount of information delivered to the user dependent upon the speed with which the user previews channels. An example of the programming information delivered to the user for fast, medium and slow channel preview rates is described in connection with

FIGS. 7 and 8

, below.




The channel information module


504


maintains a correlation between the channel preview rate and the channel information to be accessed and displayed. The correlation may be stored in the form of a table having fields for the channel preview rate, and related pointers or identifiers for the desired channel information. For example, for a first (e.g., slow) channel preview rate, the channel information module


504


may indicate that the channel number, channel logo, and program name fields should be accessed for each previewed channel. This information would then be used to access the information wherever it may be available, such as in the EPG data stored in the EPG/Graphics memory


32


. Where additional information is sought, the module


504


may store flags indicative as to whether the information should be displayed. For example, such flags may indicate that audio and or video should be associated with each currently previewed channel. There, the video would be tuned in conventional fashion, and could be displayed in a portion of the screen using conventional techniques. Additional custom information could also be provided, such as a user's notes about the channel, which may be stored in a separate location, or with the EPG data, or any desirable location.




The preview display module


508


is in communication with the channel information module


504


, and includes routines which determine how the previewed channels will be displayed. To carry out its functionality, the channel information module


504


may implement conventional graphical and display driving functionality of the graphics processing module


44


, such as providing still images and corresponding graphical and textual information for previewed channels on graphical layers that can be simultaneously displayed using conventional pixel mixing techniques. The front end


20


and AV processing module


40


can also be used by the preview display module


508


to provide video and audio for a currently previewed channel in a particular display location.




The channel preview module


500


can include a user interface for allowing the user to update the settings in the channel information module


504


, for customizing the information to be provided for the various channel preview rates, or for customizing the criteria for determining channel preview rates.




Still referring to

FIG. 6

, the channel information for the currently previewed channel remains until the user exits previewing (step


610


) or signals for the next previewed channel (step


612


). The user can exit previewing by pressing a remote control button or exit can automatically result if the next previewed channel is not requested for a predetermined time period. In the example of a jog dial, progression to the next previewed channel occurs provided that the user keeps the jog dial in a position that indicates forward or reverse previewing, with a rate dependent upon the jog dial position. The currently previewed channel index is updated for the new current channel in step


614


, and steps


604


and


606


are then repeated to update the display to include the new programming information. The channel index module (


506


,

FIG. 5

) maintains the list of channels, as described above.




The flow diagrams of

FIGS. 7A-C

illustrate an example of varying the level of channel information in accordance with the present invention. Specifically,

FIG. 7A

illustrates a situation where the jog dial


320


is rotated clockwise from the default position, such that the indicator


320




a


points to position B


1


. The control signal corresponding to this position is transmitted to the IRD


2


, and indicates a first (slow) channel preview rate. The IRD


2


updates the display


4


to provide the appropriate channel information for previewed channels as dictated by the channel preview rate.





FIGS. 8A-8C

illustrate one embodiment of displaying previewed channels and varying the amount of provided information according to preview rate. Referring first to

FIG. 8A

, at the slowest available channel preview rate, the user receives the maximum amount of information. Available channels are arranged with the currently previewed channel residing at a main channel location


802


and with other channels at remaining channel locations


804


. Preferably, the channels are arranged sequentially, such as in an arc with the main channel location


802


residing at the apex. As a channel is previewed, it resides in the main channel location


802


. When previewing in this type of arrangement, the user previews the sequence of channels, causing them to rotate along the sequence of remaining channel locations


804


and successively reside in the main channel location


802


for preview. This type of previewing may be referred to more specifically as scrolling through available channels. Preferably, particularly with the arc based arrangement, the rotation of channels to be previewed along the arc corresponds with the direction that the jog dial


320


is rotated, which provides for intuitive preview operation. Specifically, rotating the jog dial


320


clockwise into the “B” positions causes previewed channels to rotate clockwise along the arc. Where this causes a series of higher numbered channels to reside in the main channel location, this can be referred to as forward scrolling, and where it causes a series of lower numbered channels to reside in the main location it can be referred to as reverse scrolling.




In the example illustrated in

FIG. 8A

, the channel number (3) and channel logo (“ABC”) are shown for each channel previewed at the first rate. Additionally, the audio and video, as well as the title of the program on the currently previewed channel (denoted “Main Program Title” in

FIG. 8A

) residing in the main channel location


802


. For the remaining channel locations


804


, the channel number and logo continue to be shown. Additionally, still images can be shown for channels residing in the remaining channel locations


804


.




If the user continues to preview channels by maintaining the jog dial


320


in the B


1


position, the display will update after a predetermined period. Specifically, the channels will rotate clockwise along the channel information positions


802


,


804


. More specifically, the channel in remaining channel location


804




c


(2, “TNT”) will rotate into the main channel location


802


as the (next) currently previewed channel, and will have video and audio along with the other channel information. Additionally, the channel previously in the main channel location


802


(3, ABC) would rotate into remaining channel location


804




d


, the channel residing in location


804




b


would move to location


804




c


, and so on. Where necessary, certain channels would no longer be displayed (the one in location


804




f


), and previously absent channels would enter the display (e.g., to is location


804




a


).




When a channel ceases to be the currently previewed channel, the video and audio for that channel are no longer provided. However, a recent still image may be retained for display. This can be accomplished by grabbing frames of video data while the channel is the currently previewed channel, and accessing the most recent still frame for the channel after its preview period is complete. Alternatively, any previously stored still image can be displayed for those channels residing in remaining locations


804


, or even the main channel location


802


.




As the rate of previewing is increased, the amount of provided information is decreased.

FIG. 7B

illustrates the jog dial


320


with the cursor


320




a


in the B


2


position, which corresponds to a channel preview rate that is faster than that for the B


1


position. This channel preview rate can be referred to as a medium (or second) channel preview rate. As shown in the display


4


B of

FIG. 8B

, for the medium channel preview rate the information for each previewed channel is the channel number and channel logo. As with the slow previewing the channels rotate clockwise into the main channel location


802


as they are previewed. As channel preview rate increases, the amount of information provided to the user decreases. Here, for example, only the channel number and logo are provided for each previewed channel, and audio and video are not provided for the currently previewed channel. However, a still image, preferably one that is previously stored in EPG/Graphics memory


32


, may be provided for the currently previewed channel residing in the main channel location


802


.





FIGS. 7C and 8C

illustrate a still faster channel preview rate, as dictated by causing the jog dial to reside at position B


3


. For this, the fastest channel preview rate described in this embodiment, the least amount of programming information is provided. In this example, only the channel number for the currently previewed channel residing in the main channel location


802


is provided, as illustrated in the display


4

.




Channels can also be scanned in the opposite direction by causing the jog dial


320


indicator to be in the A


1


, A


2


and A


3


positions. In an arc based embodiment, maintaining the jog dial


320


in the “A” positions causes counter-clockwise rotation of channels to be previewed. The A side operation is analogous to that on the B side. Specifically, position A


1


provides a relatively slow (counter-clockwise) preview having the same amount of information as described about for the B


1


position. Similarly, A


2


position produces the same information as described for the B


2


position, and A


3


the same information as B


3


, the only difference being-previewing direction.




Thus, methods and apparatuses for providing channel information that varies dependent upon a channel preview rate controlled by user input is provided in accordance with the present invention. Although the present invention has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. For example, although certain specific information (e.g., channel number, logo, program name, audio, video) is described in connection with various channel preview rates, and certain channel preview rate breakdowns (e.g., slow, medium, fast) and criteria (e.g., jog dial position) are described, myriad alternatives may be provided without departing from the scope of the present invention (e.g., different information categories, different available rates, different controls). Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein.
