[0002] 1. Field of the Invention

[0003] The present invention relates generally to the presentation of Internet and DSS data, and more specifically to displaying a graphic user interface that facilitates a user's ability to access DSS programing, Internet information, or a combination thereof.

[0004] 2. Related Art

[0005] Over the last few years there has been a growing demand for entertainment systems that facilitate a user's ability to access multiple broadcast, information, and entertainment mediums. One type of broadcast medium is a broadcast satellite system such as a digital satellite system (DSS). DSS typically includes an antenna, an integrated receiver decoder (IRD), a television receiver (TV), and a remote controller. DSS may additionally include an analog video cassette recorder (VCR) that receives analog data for recording purposes.

[0006] In operation, the antenna receives digital bit streams from a satellite and routes the bit streams to the IRD. Typically, the digital bit streams include informational content data (e.g., video and/or audio) and programming data for one or more shows. The IRD receives the bit streams from the antenna and decodes the bit streams into data that can be presented to a user via the TV. The user selects which portion of the decoded data is transmitted from the IRD to the TV through actuation of the remote controller.

[0007] One type of information and entertainment medium is the Internet. The Internet may be accessed by a user through an Internet terminal system such as a WebTV Plus system. The WebTV Plus system typically includes a TV, an Internet terminal interconnecting the TV to the user's phone line and the user's cable line, and a remote controller that can be actuated by the user to control what information is presented on the TV by the Internet terminal. In addition, the WebTV Plus system may also include a wireless keyboard and a printer.

[0008] In operation, the Internet terminal receives cable-based broadcasts from the user's cable service provider via the user's cable line and receives Internet data from the user's Internet service provider via the user's phone line. The user selects how the received information is displayed on the TV through actuation of the remote controller.

[0009] Currently there exists a need for an integrated DSS/Internet system that permits a user to simultaneously view on a display screen a video program of a tunned channel, a decimated video of the program of the tuned channel, and a guides logo in which there is a miniature video of the current tuned channel.

[0010] To address the shortcomings of the available art, the present invention includes an integrated DSS/WebTV receiver that is communicatively connected to an Internet service provider, a DSS service provider, and (optionally) a local broadcast station to provide a display of DSS programs, Internet web sites, and local broadcast channels in a seamless fashion. The DSS/WebTV receiver generates a graphical user interface (GUI), displayed on a television screen, for facilitating a user's navigation through the DSS, Internet, and local broadcast data.

[0011] The integrated DSS/WebTV receiver of the present invention includes DSS processing circuitry (e.g., a DSS processing element such as a Texas Instruments model AV 1700 chip or an equivalent circuit) that receives wireless television communication signals, the wireless television communication signals including informational content data, i.e. audio and visual entertainment information, and programing data, e.g., scheduling data, related to the informational content data, Internet processing circuitry (e.g., a central processing unit (CPU), manufactured by Quantum Effect Design, Inc. (“QED”) or equivalent circuit, operably connected to an application specific integrated circuit (ASIC) such as a Solo model ASIC manufactured by WebTV Networks Inc.) that receives computer network communication signals and processes the received wireless television communication signals and the received computer network communication signals such that the received wireless television communication signals and the received computer network communication signals can be displayed on the television, and buffer logic for buffering signals between the DSS processing circuitry and the Internet processing circuitry. A particular feature of the present invention is that the DSS processing circuitry includes means for presenting on the television a decimated video region for simultaneously displaying, in reduced form, programs that are currently being broadcast as well as a program guides logo in which there is displayed a miniature video of the current tuned channel.

[0035] In the method and apparatus of the present invention the satellite broadcast system is described as a direct broadcast satellite system (DSS) and the Internet terminal system is described as WebTV. However, it is readily apparent to one skilled in the art that other integrated systems that can receive and display satellite and Internet data 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 menus, flowcharts and system configurations, in order to provide a thorough understanding 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 invention. In other instances, well known electrical structures and circuits are shown in block diagram form in order not to unnecessarily obscure the present invention.

[0036] Referring now to FIG. 1, an exemplary embodiment of an entertainment system 10 utilizing the present invention is shown. Entertainment system 10 includes an integrated DSS/WebTV receiver 12, a remote controller 14, and a display monitor such as a television receiver (TV) 16. Integrated receiver 12 includes an input port 18 that receives broadcast signals from a DSS antenna 20, an I/O port 22 that receives Internet data over a telephone line 23 from an Internet service provider 24, an input port 26 that receives broadcast signals from a local programming station 28 (e.g., a local cable station), and an infrared receiver 13 for receiving infrared signals from the remote controller 14. Integrated receiver 12 also includes peripheral I/O ports 30 that communicate with a plurality of peripheral devices 32. Peripheral devices 32 include, but are not limited to, a scanner 34, a printer 36, a keyboard 38, a microphone 40, and a recording device 42 such as video cassette recorder (VCR).

[0037] In operation, integrated receiver 12 receives a broadcast signal (e.g., a digital bit stream from DSS antenna 20 or analog data from local programming station 28) and performs operations (e.g., demodulating and/or decoding routines) on the broadcast signal to produce video and audio information to be displayed to the user via TV 16. Integrated receiver 12 also receives Internet signals from Internet service provider 24 and performs operations (e.g., decompressing and/or decoding routines) on the Internet signals to produce video and audio information to be displayed to the user via TV 16. The user controls the display of the Internet-derived and broadcast-derived audio and video information using remote controller 14, as discussed in further detail below.

[0038] Referring now to FIGS. 2A-2D, simplified block diagrams of the DSS/WebTV receiver's circuitry are illustrated. Turning now to FIG. 2A, DSS/WebTV receiver 12 includes a DSS processing element 200 (e.g., an AV7100 chip manufactured by Texas Instruments, Inc.), an Internet processing element 202 (e.g., a QED central processing unit (CPU), manufactured by Quantum Effect Design, Inc., operably connected to an application specific integrated circuit (ASIC) such as a Solo ASIC manufactured by WebTV Networks Inc.), and buffer logic 204 (e.g., a GOM logic ASIC manufactured by Sony Corp./Sony Electronics Inc.) interconnecting DSS processing element 200 and Internet processing element 202. DSS processing element 200 converts signals received from the DSS service provider into digital signals that are transmitted to Internet processing element 202 via Buffer logic 204. Internet processing element 202 converts digital signals received from Internet service provider 24 and Buffer logic 204 into data that can be displayed on TV 16 (FIG. 1), as discussed in further detail below. Buffer logic 204 acts as a buffer that shields the processor and internal bus of DSS processing element 200 from the processor and internal bus of Internet processing element 202. Buffer logic 204 also receives signals from local programing stations 28 (e.g., local cable or broadcast stations) and transmits the signals, in original or decimated form, to Internet processing element 202, as discussed below.

[0039] DSS processing element 200 is connected to DSS antenna 20 via a low noise block down converter 206 (LNB) and a front end unit 208 (FE). LNB 206 converts a Ku-Band signal received from a satellite to an L-Band signal. The L-Band signal is then transmitted to FE 208. FE 208 is a tuning device that amplifies, demodulates, and converts the signal received from LNB 206. The converted signal emerges as a data bit stream that is in an encrypted, encoded, and compressed form. FE 208 also performs error correction on the data bit stream. DSS processing element 200 examines and filters the data bit stream received from FE 208 based on user-selected and DSS service authorized criteria. It should be noted that the data bit stream carries video and audio data representing various DSS channels, programing data corresponding to the video and audio data, and Internet data that is transmitted over DSS, as discussed in further detail below.

[0040] An SDRAM 210 and an IEEE 1394 (Standard for High Performance Serial Bus) interface 212 are connected to DSS processing element 200. SDRAM 210 acts as an intermediate buffer for the storage of data as DSS processing element 200 performs various processing steps such as decoding, decryption, and decompression routines. Interface 212 interconnects DSS processing element 200 to peripheral devices 32 (FIG. 1) thereby permitting DSS processing element 200 to interact with peripheral devices 32.

[0041] A smart card 214 is connected to DSS processing element 200 via a card interface (not shown). Smart card 214 includes a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM). Smart card 214 determines whether the user has the authorization to receive certain data (e.g., audio/video data from a pay TV station) using the authorization information stored in its memory. If smart card 214 determines that the user is authorized, smart card 214 provides a decryption key to the DSS processing element 200 which, in turn, decrypts the audio/video data via the decryption key. It should be noted that although a smart card has been shown, other conditional access modules known by those skilled in the art are deemed within the scope of the present invention.

[0042] A ROM 216 is connected to DSS processing element 200 and Buffer logic 204 via a data bus 218 and an address bus 220. ROM 216 stores fundamental operating routines to be executed by DSS processing element 200. The operating routines include, but are not limited to, initializing routines, downloading routines, and upgrading routines.

[0043] Buffer logic 204 receives audio data, video data, Internet/DSS data, and peripheral generated data from DSS processing element 200. Buffer logic 204 processes and/or relays the received data to Internet processing element 202, as discussed in further detail below. Buffer logic 204 also receives input from a user via a remote controller input 242 and/or a remote keyboard input 244. Buffer logic 204 relays the user input to Internet processing element 202 and, if needed, adjusts the LED display on a front panel 246 of the integrated DSS/WEBTV receiver 12. Buffer logic 204 may also receive local broadcast signals via a terrestrial tuner 236 (attached to an antenna or cable line) and analog to digital processing elements 238 and 240. The particular local broadcasting channel received is selected by the user via remote controller 14 and Internet processing element 202. Buffer logic 204 processes and/or relays the digitized local broadcast to Internet processing element 202, as discussed in further detail below.

[0044] Internet processing element 202 includes a QED microprocessor and a Solo chip. The QED microprocessor processes routines stored in internal and external memories (e.g., ROM 224) and the Solo chip provides the QED microprocessor with peripheral functions such as, but not limited to, audio processing, remote control signal processing, memory assignment, graphics processing, and discrete I/O functions. Internet processing element 202 also includes an internal soft modem 222 that communicates with the Internet service provider 24 via a subscriber line interface coder/decoder (SLIC/Codec) interface 222. SLIC/Codec interface 222 acts as a digital to analog converter between Internet processing element 202 and phone line 23. Information processed by soft modem 226 is either stored in a memory (e.g., Hard Disk Dive (HDD) 228) or is further processed by a graphics engine of the Solo chip such that the information from the Internet can be displayed on TV 16 (FIG. 1).

[0045] ROM 224, HDD 228, and Flash memory 230 are connected to Internet processing element 202 via a data bus 233. ROM 224 stores the fundamental operating routines of Internet processing element 202. The fundamental operating routines include, but are not limited to, initializing routines, downloading routines, upgrading routines, and the like. Flash memory 230 stores all semi-volatile applications such as, but not limited to, icon generation, GUI generation, and the like. HDD 228 stores the volatile information that is the most likely to be modified. Such volatile information includes, but is not limited to, Internet data or DSS/Internet data that is to be displayed on TV 16, as discussed in further detail below. A SDRAM 232 is connected to Internet processing element 202 and acts as an intermediate buffer for the storage of data as Internet processing element 202 performs various processing steps such as decoding, decryption, and decompression routines.

[0046] A smart card 234 is connected to Internet processing element 202 via a card interface (not shown). Smart card 234 includes a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM). Smart card 234 determines whether the user has the authorization to access certain web sites (e.g., web sites displaying or discussing mature subject matters) using the authorization information stored in its memory. If smart card 234 determines that the user is authorized, smart card 234 provides a decryption key to the Internet processing element 202 which, in turn, decrypts the received Internet data via the decryption key. It should be noted that although a smart card has been shown, other conditional access modules known by those skilled in the art are deemed within the scope of the present invention.

[0047] Internet processing element 202 receives DSS data and local broadcast data from Buffer logic 204 and blends the received data with data received from the Internet service provider 24. Afterwards, Internet processing element 202 transmits the blended data to DAC (digital to analog converters) for displaying the blended data on TV 16. It should be noted that the video portion of the data may be output in an S-Video, composite, or RF format.

[0048] Internet processing element 202 also receives DSS/Internet data from Buffer logic 204 and stores the DSS/Internet data on HDD 228. The DSS/Internet data represents, e.g., web sites that the user can access via the “Best of Web” feature of the GUI, as discussed in further detail below. Storing DSS/Internet data on HDD 228 enables a user to access predetermined web sites in real time, thereby, removing the access and interconnection delays traditionally encountered when communicating with web sites over a phone line.

[0049] Turning now to FIG. 2B, a simplified block diagram of Buffer logic 204 is shown. In general, Buffer logic 204 carries three types of information between DSS processing element 200 and Internet processing element 202: basic command signals (e.g., tune to channel 100), basic status signals (e.g., tuning complete), and large bandwidth signals (e.g., program guide information, web sites for caching in HDD 228, firmware updates, and the like). It should be noted that the internal routing of video signals from DSS processing element 200 and terrestrial tuner 236 is illustrated in FIG. 2C and discussed below.

[0050] Buffer logic 204 includes two narrowband (e.g., 2 KBytes) FIFO buffers 250 and 252 and one wideband (e.g., 64 KBytes) FIFO buffer 254. FIFO buffers 250-254 are connected to DSS processing element 200 via a multiplexer 256, an address decoder 258, and an interrupt controller 260. FIFO buffers 250-254 are connected to Internet processing element 202 via a multiplexer 262, a DMA controller 264, an address decoder 266, and an interrupt controller 268.

[0051] In operation, DSS processing element 200 periodically downloads large amounts of data (e.g., program guide information, web sites for caching in HDD 228, firmware updates) to FIFO buffer 254 by signaling address decoder 258 and downloading the data to multiplexer 256. Multiplexer 256 receives the address of FIFO buffer 254 from address decoder 258 and relays the data from DSS processing element 200 to FIFO buffer 254. Interrupt controller 268 is, preferably, programmed to transmit an interrupt signal to Internet processing element 202 when the amount of data stored in FIFO buffer 254 reaches a predetermined level (e.g., 30 KBytes). In response to the reception of the interrupt signal, the QED microprocessor (not shown) downloads the data stored in FIFO buffer 254 by signaling address decoder 266 and instructing DMA controller 264 to transport the incoming data to a selected memory location (e.g., HDD 228, flash memory 230, or SDRAM 232). Address decoder 266, in turn, transmits the address of FIFO buffer 254 to multiplexer 262 and DMA controller directs the incoming data from multiplexer 262 to the selected memory.

[0052] In addition to routing large amounts of data from DSS processing element 200 to Internet processing element 202, Buffer logic 204 facilitates the transfer of commands and responses between DSS processing element 200 and Internet processing element 202. For example, when the user requests, via remote controller 14, a new DSS channel, the signal from remote controller 14 is received by Buffer logic 204 and routed to Internet processing element 202. Internet processing element 202, in turn, transmits a high level “tune to new channel” command to FIFO buffer 252 by signaling address decoder 266 and transmitting the command to multiplexer 262. Afterwards, address decoder 266 supplies multiplexer 262 with the address of FIFO buffer 252 and multiplexer 262 routes the “tune to new channel” command to FIFO buffer 252. After the “tune to new channel” command is received, interrupt controller 260 detects the reception of the command by FIFO buffer 252 and transmits an interrupt signal to DSS processing element 200. The interrupt signal notifies DSS processing element 200 that a pending command/request is stored in FIFO buffer 252. Upon receipt of the interrupt signal, DSS processing element signals address decoder 258. Address decoder 258, in turn, transmits the address of FIFO buffer 252 to multiplexer 256 and multiplexer 256 downloads the “tune to new channel” command from FIFO buffer 252 to DSS processing element 200.

[0053] Upon receipt of the “tune to new channel” command, DSS processing element 200 executes a “tune to new channel” routine that is stored on ROM 216. The routine includes a complex sequence of instructions that are required to enable DSS processing element 200 to tune to the new channel. The instructions include, but are not limited to, determining the identity of the new channel, determining which DSS satellite carries the new channel, the bit stream location of information transmitted on the new channel (e.g., every fifth time slot), determining if the user is authorized to view the new channel (via smart card 214), and decryption instructions for decrypting the data carried on the new channel.

[0054] Once DSS processing element 200 completes executing the “tune to new channel” routine, DSS processing element transmits a status message to Internet processing element 202. The status message indicates whether the requested command has been executed. Some exemplary status messages include “channel tuned,” “channel not authorized,” “system inoperative,” and the like. To transmit the status message to Internet processing element 202, DSS processing element 200 transmits the status message to multiplexer 256 and signals address decoder 258. Address decoder 258, in response, transmits the address of FIFO buffer 250 to multiplexer 256 which, in turn, relays the status message to FIFO buffer 250. Afterwards, interrupt controller 268 detects the reception of the status message by FIFO buffer 250 and transmits an interrupt signal to Internet processing element 202. In response to the reception of the interrupt signal, Internet processing element 202 downloads the status message stored in FIFO buffer 250 by signaling address decoder 266 and instructing DMA controller 264 to transport the incoming data to a selected memory location (e.g., internal memory, HDD 228, flash memory 230, or SDRAM 232). Address decoder 266, in turn, transmits the address of FIFO buffer 250 to multiplexer 262 and DMA controller directs the status message from multiplexer 262 to the selected memory. Finally, Internet processing element 202 examines the stored status message and transmits the appropriate response to the user. Some exemplary responses include displaying the new channel on TV 16, displaying an “unauthorized” message, displaying an “error” message, and the like.

[0055] Turning now to FIG. 2C, a simplified block diagram of the internal routing of video signals in integrated DSS/WebTV receiver 12 is illustrated. There are three sources for the video signals input to integrated DSS/WebTV receiver 12: video signals received via DSS antenna 20, video signals received from a peripheral device (e.g., a camcorder or other video recording device) via peripheral bus interface 212, and video signals received from terrestrial tuner 236. The DSS and peripheral device video signals are processed (decoded, decompressed, etc.) by DSS processing element 200 and relayed to Buffer logic 204. The terrestrial video signals are converted to a digital format by digital to analog converter 240 and relayed to Buffer logic 204.

[0056] Upon reception of the video signals, Buffer logic 204 routes the video signals through a 3×2 multiplexer 270. One output of multiplexer 270 is connected to a video processor 272 located within Buffer logic 204 and the other output of multiplexer 270 is connected to a video processor 274 located within Internet processing element 202. Each video processor 272 and 274 either performs a decimation process on the video signals or allows the video signals to pass therethrough. If the video signals undergo the decimation process, the decimated video signals will produce a decimated video frame on TV 16. If the video signals do not undergo the decimation process, the video signals will produce a full-screen video frame on TV 16. The decimation process is discussed in further detail below.

[0057] Video processors 272 and 274 transmit the video signal (decimated or unprocessed) to a blending function 278 of Internet processing element 202. Signals received from the Internet (via the phone line or DSS transmission) are also transmitted to blending function 278 after being processed by a web graphics engine 276. As discussed above, web graphics engine 276 processes the Internet signals into a form that can be displayed on TV 16. Blending function 278 is a software program stored in memory (e.g., internal memory, ROM 224, or flash memory 230) that Internet processing element 202 executes to integrate the received signals into a form that can be displayed on TV 16. After undergoing the blending function, the blended signals are transmitted to video encoders and digital to analog converters 280 which, as discussed above, display the blended signals on TV 16. It should be noted that the blending function and decimating procedure are only executed in response to a request from a user. For example, if a user is merely watching a TV show, the blending function and the decimating procedure are not executed. However, if the user requests a GUI (as discussed below), both the blending function and the decimation process may be executed.

[0058] Referring now to FIG. 2D, an exemplary flowchart 282 illustrative of a user accessing Internet and/or DSS data via the GUI generated by the DSS/WebTV receiver 12 is shown. Initially, at step 284, the GUI is displayed on TV 16 by DSS/WebTV receiver 12. As discussed above, the GUI is stored in flash memory 230 and displayed on TV 16 by Internet processing element 202. Next, at step 286, Internet processing element 202 determines if the user has selected an Internet-related icon in the GUI, as described in further detail below. If the user has selected an Internet-related icon, Internet processing element 202, at step 294, displays the Internet data (e.g., a web site) that corresponds to the selected icon. If the user has not selected an Internet-related icon, Internet processing element 202, at step 288, determines if the user has selected a DSS-related icon. If the user has selected a DSS-related icon, Internet processing element 202 relays the user's request to DSS processing element 200 and displays, at step 296, the DSS data corresponding to the selected icon as provided by DSS processing element 200. If the user has not selected a DSS-related icon, Internet processing element 202, at step 290, determines if the user has selected an exit key (preferably located on remote controller 14). If the user has selected the exit key, Internet processing element 202, at step 292, discontinues the display of the GUI. If the user has not selected the exit key, Internet processing element 202 returns to step 286 and continues to monitor for the selection of Internet-related icons and/or DSS-related icons.

[0059] Referring now to FIG. 3, one embodiment of remote controller 14 is shown. As discussed above, remote controller 14 is utilized by a user to transmit commands and make program selections in accordance with the teachings of the present invention. In operation, the user may actuate a plurality of operation keys of remote controller 14 to control how the integrated receiver 12 displays video and audio information on TV 16. The plurality of operation keys include, but are not limited to, a direction pad 302 having a plurality of direction keys 318-324 and an enter key 326, a “GUIDE” key 304 for prompting integrated receiver 12 to display an electronic program guide on TV 16, a “FAVORITE” key 306 for prompting integrated receiver 12 to display a user-customized favorite channel screen on TV 16, a “HOME” key 308 for prompting integrated receiver 12 to display a Home screen on TV 16, a “CATEGORY” key 310 for prompting integrated receiver 12 to display a category guide on TV 16, an “OPTIONS” key 312 for prompting integrated receiver 12 to display an option palette on TV 16, a “SELECT” key 314 for prompting integrated receiver 12 to display a feature selected by the user on TV 16, and an “EXIT” key 316 for prompting integrated receiver 12 to discontinue displaying a selected menu or feature.

[0060] Referring now to FIG. 4, a simplified a block diagram of the remote controller circuitry is illustrated. Remote controller 14 has an infrared originating device 400, a set of operation keys 402 (corresponding to the operation keys of FIG. 3), a CPU 404, a ROM 406 and a RAM 408. CPU 404 receives a signal sent from an operation key 402 through an input port 410. The signal is processed according to a program stored in ROM 406. RAM 408 is used as a working space for generating a transmitting code. The transmitting code is sent to the infrared originating device 400 through an output port 412 and converted into an infrared signal. The infrared signal is transmitted to infrared receiver 13 of integrated DSS/WebTV receiver 12.

[0061] Referring now to FIG. 5, a block diagram of data 500 stored in a portion of HDD 228 and/or flash memory 230 (FIG. 2A) is illustrated. As discussed above, HDD 228 and/or flash memory 230 store guide data 502, channel data 504, and program data 506. Guide data 502 includes, but is not limited to, date information 508, time information 510, a segment number identifier 512 that identifies the data segment, a transponder list 514 that identifies the transponder transmitting the data segment, and a channel list 516 that identifies a channel number associated with a portion of data.

[0062] Channel data 504 includes a channel number 518, a channel name 520 (e.g., the call sign of a broadcast station), a logo ID 522 (e.g., an identification of the channel logo), a data ID 524 that identifies a channel of MPEG video data or MPEG audio data, a number of programs 526 that identifies the number of programs to be transmitted on a channel during a predetermined time frame, and a first program offset 528 that identifies the offset from the header to the first channel data in a segment.

[0063] Program data 506 includes a program title 530, a program start time 532, a time length 534 indicating the duration of the program, a program category 536 (e.g., movies, news, sports, etc.), a program subcategory 538 (e.g., subcategories of sports such as baseball, basketball, football), a program rating 540 (e.g., “R”, “PG”, “G”) and a program description 542 that provides a detailed description of the program (e.g., story line, actors).

[0064] Referring now to FIG. 6, DSS processing element 200 generates a pointer table 544 in response to the reception of data 500. DSS processing element 200 stores the pointer table 544 in HDD 228 and/or flash memory 230. Pointer table 544 contains the location of channel data 546 and program data 548 in HDD 228 and/or flash memory 230. In operation, when the user selects a program for viewing (via controller 14), Internet processing element 202 transmits a “tune to new channel” request to DSS processing element 200. In response, DSS processing element 200 executes a channel locating routine (stored in ROM 216) and determines the location of the channel data and program data corresponding to the selected program by accessing pointer table 544. After the location determination is completed, DSS processing element 200 tunes to the new channel and transmits a status message to Internet processing element 202 via Buffer logic 204. If the user is authorized to receive the new channel (and no errors have occurred), Internet processing element 202 receives the video and audio signals from DSS processing element 200 and Buffer logic 204, performs any necessary blending and/or decimating techniques, and displays the requested program on TV 16.

[0065] Referring now to FIG. 7, a Home screen 550 of a Graphical User Interface (GUI) of the present invention is shown. The GUI, generated by DSS processing element 200 and Internet processing element 202, is displayed on TV 16 and permits a user to select a channel for viewing and to access the Internet. GUI home screen 550 includes, but is not limited to, a “Guide” icon 552, a “WebTV” icon 554, a “Favorites” icon 556, a “TV Planner” icon 558, a “Mail” icon 560, a “Setting” icon 562, a “How To” icon 564, and a movable highlight box (or pointer) 568. Icons 552-564 represent accessible screens, pull-down menus, and features that a user can display on TV 16, as discussed below. GUI Home screen 550 also includes a scrolling ticker region that displays information about upcoming events (e.g., upcoming pay-per-view movies and sporting events) and a decimated video region 569 that displays, in reduced form, the current DSS channel (including channel name, channel number, and program title) being viewed by the user.

[0066] In operation, the user positions highlight box 568 on icons 552-564 by pressing direction keys 318-324 of remote controller 14 in the appropriate direction. Once the user has positioned the highlight box 568 on a desired icon, the user can display the menu corresponding to the highlighted icon by pressing enter key 326 of controller 14. It should be noted that some menus (e.g., “Guides”, “Favorites”) can be displayed by highlighting a corresponding icon in GUI Home screen 550 or by pressing a corresponding key of remote controller 14. Selection of a particular icon by the user by means of highlight box 568 and enter key 326 is noted by either Internet processing element 202 or DSS processing element 200, depending on the icon. In response to the user's selection of Internet-related icons, Internet processing element 202 displays Internet web page data from storage device HDD 228, or flash memory 230, or carries out functions which correspond to the selected icon from routines stored in ROM 224. It should be noted that some of the data stored in HDD 228 or flash memory 230 is downloaded by DSS processing element 200, as described above, from a DSS service provider. In response to the user's selection of DSS-related icons, DSS processing element 200 displays informational content data (audio and video data) received from the DSS service provider, displays the GUI received from storage device HDD 228 or flash memory 230, or carries out functions which correspond to the selected icon from routines stored in ROM 216.

[0067] Referring now to FIG. 8, an exemplary flowchart 570 illustrative of a user turning on entertainment system 10 and accessing GUI Home screen 550 is shown. Initially, at step 572, the user powers up entertainment system 10 by pressing the power button(s) on remote controller 14. Upon power up, at step 574, the channel that was previously displayed when entertainment system 10 powered down is displayed on TV 16. Afterwards, at step 576, integrated DSS/Web TV receiver 12 monitors signals from remote controller 14 to determine if the user has pressed “HOME” key 308. If “HOME” key 308 has not been pressed, integrated DSS/Web TV receiver 12 continues to display the previously displayed channel and monitor signals from remote controller 14. If “HOME” key 308 has been pressed, integrated DSS/Web TV receiver 12, at step 578, displays GUI Home screen 550 on TV 16.

[0068] As discussed above, GUI Home screen 550 contains a decimated video region 569 that displays the current channel selected by the user. A full-screen video frame is reduced to a decimated video frame by a decimation process. The decimation process is a down-conversion filtering process that reduces the definition or resolution of the full-screen video frame to a frame size convenient for display in the GUI. Decimating the full-screen video frame results in a decimated video frame having pixel dimensions that are a fraction of the dimensions of the full-screen video frame. The decimation process of the present invention uses known filtering and digital signal processing techniques to eliminate a number of pixels from the full-screen video frame. For example, one exemplary decimation technique might drop every other pixel in the vertical and horizontal directions (X,Y) from the full-screen video frame, thereby providing a decimated video frame having pixel dimensions that are one-half of the X,Y pixel dimensions of the full-screen video frame, i.e., a window {fraction (1/16)} of actual size. The number of pixels eliminated from the full-screen video frame is determined by the size of the decimated video frame to be displayed in the GUI. In one embodiment, the decimated video frame has, but is not limited to, pixel height and width that are one-fourth of the pixel dimensions of the full-screen video frame. As discussed above, decimated video is stored in a memory (e.g., HDD 228 and/or flash memory 230) for later display.

[0069] Referring now to FIG. 9, a plurality of features and/or menus that the user can access via GUI Home screen 550 are shown. As discussed above, GUI Home screen 550 includes a decimated video region, a so-called picture-in-picture (PIP) region 569 that displays a reduced frame size video 580 of a currently selected program and a scrolling ticker region 566 that displays information about upcoming events, stocks, sport scores, and the like. The user can access an “Article Summary” icon 567 or a “Web Page” icon 571 associated with the information displayed on ticker region 566 by selecting the ticker region 566 via the highlight box (or pointer) 568 (shown in FIG. 7). “Article Summary” icon 567, if selected, provides the user with additional information about the upcoming event that is not otherwise displayed on ticker region 566. “Web Page” icon 571, if selected, provides the user with an interactive setting for receiving additional information about the upcoming event. For example, ticker region 566 may display a message that states that an upcoming football game will be shown on channel 4 at 2 pm on Nov. 24, 1999. If the user desires to have further information about the game, the user may select “Article Summary” icon 567 to receive information such as the football team's records, conferences, and the like. The user may also select “Web Page” icon 571 to access each team's web page and/or the football portion of the web page of channel 4. As discussed above, these web pages are downloaded from the DSS network, stored on HDD 228, and retrieved from the HDD 228 by the Internet processing element 202 in response to selection of an icon by the user.

[0070] GUI Home screen 550 also includes a plurality of icons that permit the user to access screens, pull-down menus, and/or features that facilitate the user's navigation through DSS channels and the Internet, as discussed below. In general, the user can access a menu or feature by selecting an icon (i.e., positioning highlight box 568 over the icon) and pressing enter key 236. The following descriptions describe the screens, pull-down menus, or features that the user can access by selecting the various icons in GUI Home screen 550. As discussed above, the selection of a particular icon by the user by means of highlight box 568 and enter key 326 is noted by either Internet processing element 202 or DSS processing element 200, depending on the icon. In response to the user's selection of Internet-related icons, Internet processing element 202 displays Internet web page data from storage device HDD 228, or flash memory 230, or carries out functions which correspond to the selected icon from routines stored in ROM 224. It should be noted that some of the data stored in HDD 228 or flash memory 230 is downloaded by DSS processing element 200, as described above, from a DSS service provider. In response to the user's selection of DSS-related icons, DSS processing element 200 displays informational content data (audio and video data) received from the DSS service provider, displays the GUI received from storage device HDD 228 or flash memory 230, or carries out functions which correspond to the selected icon from routines stored in ROM 216.
