Definitions

  • This disclosure relates generally to presentation of information on a display device, and in particular but not exclusively, relates to an interactive television "ticker” having user controllable display features, such as personal video recorder (PVR)-like capabilities including fast forward, rewind, pause, slow motion, skip, and speed control.
  • PVR personal video recorder
  • tickers that are present on sports channels typically scroll game scores or game schedules. Tickers that are present on news channels scroll the latest headlines, weather reports, or brief news updates.
  • Tickers are generally encoded in the same analog or digital signal as the television signal. For instance, with Motion Pictures Experts Group (MPEG) digital encoding, the ticker information is included along with the MPEG stream. A graphics generator or other mechanism generates the ticker information at a production studio (or other location) and then combines the ticker information with the television signal. The television signal is then broadcast to viewers. Obviously, with this current implementation, viewers have no control over the content, format, layout, or other presentation aspect of the ticker on their television (including whether or not to even display the ticker), since the production studio maintains such control and since the ticker information is integrated with the received television signal.
  • MPEG Motion Pictures Experts Group
  • tickers Because of this lack of control, viewers share common frustrations with tickers. For example, most tickers scroll from left to right at the bottom of the television screen at a certain speed set by the production studio. Many times, a stock price or sports score of interest to the viewer has scrolled by during a moment that the viewer was not looking at the television screen or was otherwise distracted, thereby causing the viewer to miss the ticker item. As a result, the viewer has to wait until the ticker item scrolls by again. This can be an annoying wait for the viewer if there are a large number of ticker items to scroll through before the item of interest reappears.
  • tickers may move too slowly or too fast. If they move too fast, then the viewer may miss items of interests. If they move too slowly, then the viewer is forced to wait and view all items in the ticker until an item of interest is displayed — this can be very inconvenient if the viewer is in a rush and cannot afford the spend time to watch a ticker.
  • Some tickers "freeze" a displayed item momentarily before moving on to display the next item, so as to give the viewer a somewhat extended opportunity to read the item before it is taken off the screen.
  • some viewers may find this feature to be "too fast" in that the item of interest is taken off the screen before the viewer may have the chance to write down the information, point out the item to another viewer, etc.
  • this ticker implementation may be "too slow” since the ticker has to pause on the screen for each and every item.
  • Interactive television is increasing in use and popularity. With interactive television, viewers can now access the Internet through their television sets, as well as being able to receive interactive programming and content.
  • interactive television tickers interactive service providers can deliver national news, sports, entertainment, weather, and business feeds to interactive television subscribers. Although such interactive television tickers provide some user/viewer control, such as being able to select subjects of interest, the ticker itself behaves in much the same way as a broadcast television ticker — the viewer has little control over the presentation of information in the ticker (e.g., if the viewer misses an item, the viewer usually has to wait until that item scrolls by again).
  • FIG. 1 is a block diagram of an example interactive video casting system that can implement tickers in accordance with an embodiment of the invention.
  • Figure 2 is a block diagram illustrating example components that can be included in the system of Figure 1 to provide tickers in accordance with an embodiment of the invention.
  • FIG 3 is a block diagram of an embodiment of a client terminal that can be used in the system of Figure 1 to present tickers.

  • FIG. 7 is a block diagram of components involved in implementation of user control of ticker display features in accordance with an embodiment of the invention.
  • Figure 8 is a flowchart illustrating operation of a ticker having user controllable display features in accordance with an embodiment of the invention.
  • Embodiments of a ticker having user controllable display features such as PVR-like capabilities that affect or otherwise change movement of the ticker (including speed control, fast forward, rewind, pause, lock, skip, slow motion and the like) are described herein.
  • PVR-like capabilities that affect or otherwise change movement of the ticker (including speed control, fast forward, rewind, pause, lock, skip, slow motion and the like) are described herein.
  • numerous specific details are given to provide a thorough understanding of embodiments of the invention.
  • the invention can be practiced without one or more of the specific details, or with other methods, components, materials, etc.
  • well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.
  • ticker as used herein is intended to generally describe a presentation of information on a display screen, such as a display screen for a television, and is not intended to be limited solely to implementations where the information is presented in a manner to exactly mimic a stock market ticker.
  • the ticker can comprise text and graphics that are scrolled or otherwise presented in a region of the display screen, along with a television image (such as an image from a live broadcast or from a recorded program).
  • a television image such as an image from a live broadcast or from a recorded program.
  • ticker is merely illustrative of a technique to present dynamic ticker information, and that this term, in some embodiments, can encompass implementations where the ticker information is presented via screen segments of information, text segments, one- sentence-at-a-time, one-line-at-a-time, one-word-at-a-time, and the like, rather than the traditional format of one-character-at-a-time typically associated with stock market tickers.
  • the term “scrolling” is used generically herein to refer not only to vertical movement from bottom to top, but also movement from right to left (often referred to as "crawl") or movement in other directions.
  • an embodiment of the invention provides a ticker that can be implemented in a television system, such as an interactive television system.
  • the ticker has user controllable display features, such as PVR-like capabilities of fast forward, rewind, skip, slow motion, or pause.
  • PVR-like capabilities of fast forward, rewind, skip, slow motion, or pause.
  • fast forward or skip operations give the user the ability to quickly cycle through items in the ticker that are of less interest.
  • Slow motion or pause operations give the user additional time, if needed, to view an item before it completes its scrolling.
  • Various speed controls are available to allow adjustment of the scroll speed of the ticker.
  • the various user controllable features are implemented in a dynamic manner by the user as the user views the ticker, as compared to static settings made through a configuration screen.
  • FIG. 1 shows an example of an interactive video casting system 100 for distributing ticker content, Internet content, and television content according to an embodiment of the invention.
  • the system 100 can be integrated with a cable television distribution system to provide interactive television tickers. It is to be appreciated that in another embodiment, tickers having user controllable features may be implemented in systems that are not necessarily interactive in nature.
  • the system 100 includes an Internet 102, a plurality of content sources 104, a plurality of distribution centers (depicted as the head-ends or H/Es 106), and a plurality of client terminals 108 (depicted as set top boxes).
  • a content source 104 is depicted as receiving data from data feeds 112, advertisement servers 114, image sources 116, and streaming video sources 118.
  • the content source 104 may also receive content from a broadcast video source. For the sake of clarity and to avoid clutter, not all of these sources are shown in Figure 1 for each content source 104.
  • the plurality of content sources 104 is coupled to the Internet 102.
  • a content source 104 may comprise a web site portal such as Go2Net.comTM, or a news web site such as CNN.comTM, or other types of sources.
  • Each content source 104 may have various data feeds 112, servers 114, and sources 116/118 coupled to it.
  • news or stock quote feeds 112 may be fed into the content source 104.
  • Servers 114 may provide advertisements for insertion into multimedia content delivered by the content source 104.
  • Sources 116 and 118 may provide images 116, streaming video 118, and other content to the content source 104.
  • Various other feeds, servers, and sources may also be coupled to the content source 104 of Figure 1.
  • An example configuration of components that can be integrated with the system 100 to provide ticker information to client terminals 108 is shown in Figure 2.
  • the Internet 102 comprises a network of networks and is well known in the art. Communications over the Internet 102 can be accomplished using standard protocols such as transmission control protocol/internet protocol (TCP/IP), hypertext transfer protocol (HTTP), file transfer protocol (FTP), or other protocols.
  • TCP/IP transmission control protocol/internet protocol
  • HTTP hypertext transfer protocol

  • the Internet 102 is coupled to the plurality of distribution centers 106, and each distribution center 106 is in turn coupled to a plurality of client terminals 108, which may comprise a set top box, a PC, an interactive television set, or another type of communication device or display device.
  • communications channels or networks 120 (which can include satellite delivery sources/networks) apart from the Internet 102 may couple one or more content sources 104 to one or more distribution centers 106.
  • One example of such an alternate path for communications is illustrated by a first dashed line 120 in Figure 1.
  • peering connections may exist between distribution centers 106.
  • One example of such peering is illustrated by a second dashed line 122 in Figure 1.
  • Other communications configurations are also possible and are included within the scope of the present invention.
  • Caches 110 may be provided at (or otherwise coupled to) the distribution centers 106. Such caches 110 may be used to increase the performance in the delivery of multimedia content (including ticker data) to the client terminals 108. For example, larger files for video and other high bandwidth content may be stored in such caches 110, which may be closer-in-time to the client terminals 108 than to the content sources 104. In addition, reliability and guaranteed bandwidth may be provided because the Internet 102 is not in-between such caches 110 and the client terminals 108. In one embodiment, the caches 110 or other storage media in the system 100 can store ticker information, rather than or in addition to having such information buffered, cached, or otherwise stored at the client side.
  • servers may be present in the distribution centers 106, with such servers including or being coupled to the caches 110 or other storage media. Alternatively or in addition, these servers may be located remotely from but still communicatively coupled to the distribution centers 106, via the Internet 102 or other communications channels or networks. Examples of such servers that can be used in connection with providing ticker information to client terminals 108 are shown in Figure 2.
  • different or multiple portals may be used to access the information provided through the interactive video casting systems of Figure 1 , based on the type of client terminal being used by the end user. That is, for example, a television portal may be provided for an end user that uses a television set coupled to the client terminal 108 to access the information.

  • the adapter converts the television signals, the Internet or web page content, or other information provided from the interactive video casting system into a digitized format or other format that is compatible with the operational features of the particular client terminal 108.
  • a cable service provider can deliver signals having different formats to the various client terminals 108, with the client terminals not necessarily having special adapters. Therefore, as an example, the cable service provider or other party can generate/deliver information (e.g., television programming, web page content, ticker information, and the like) having a format that is compatible for end users that receive the information via a television set. The cable service provider or other party can also generate/deliver the same information (e.g., simultaneously with the television portal on the same communication link, separately on a different communication link, on-demand independent of the television portal, and the like) using a format that is compatible with end users that receive the information via PCs, PDAs, cellular telephones, and the like.

  • the sources that can provide this data can include entities such as ReutersTM, The Sporting NewsTM (TSN), Associated PressTM (AP)TM, and others.
  • the ticker data from the data feeds 200 comprises "raw" unformatted data (e.g., data with minimal or no formatting or graphics).
  • the raw ticker data is provided to a feed server 202.
  • the feed server 202 operates as a content aggregator that pulls or otherwise receives the raw ticker data from the data feeds 200.
  • the feed server 202 also performs data manipulation on the received ticker data to manipulate the data into a database format so that the data can be indexed and stored.
  • a feed engine 204 which can be embodied in software or other machine-readable instructions stored on one or more machine-readable media according to an embodiment, can reside and run in the feed server 202 to perform at least some of this data manipulation.

  • California weather information can be segregated from Oregon weather information in the database 208 in a manner that client terminals 108 of California users do not receive Oregon weather information, unless specifically requested. This feature improves transmission efficiency and transmission time, since the bandwidth of communication paths to certain client terminals 108 are not clogged by non- relevant ticker data.
  • the production server 206 can also perform data manipulation, such as before the data is stored in the database 208, while it is stored in the database 208, or after the data is retrieved from the database 208 for transmission to client terminals 108.

  • This implementation may be present, for example, where a particular client terminal 108 may have limited software, storage, and processing capacity to perform the appropriate user controllable operations — therefore, the operations are performed remotely at a server rather than locally at that client terminal 108, and then a ticker presentation reflecting the user controlled operation (e.g., a paused ticker item) is sent from the server to the client terminal 108 for display.

It also should be noted that the client terminal 108 is only one embodiment of the invention and that some or all of the components described as embodied in the client terminal 108 can be incorporated into a client television rather than in a separate device. A bus 301 is shown symbolically to depict coupling between the various components.
  • the client terminal 108 receives ticker data from the distribution server 218, and then performs the appropriate processing of the data to allow the data to be displayed in a ticker on a display screen of a television set.
  • the client terminal 108 can be passive in that it receives the ticker data (as well as updates) when the data is sent by the distribution server 218, independently of whether the client terminal 108 requested the ticker data (e.g., the distribution server 218 "pushes" the ticker data to client terminals 108).
  • the client terminal 108 can poll or otherwise explicitly request the ticker data from the distribution server 218, including polling the distribution server 218 for updated data (e.g., the client terminal 108 "pulls" the ticker data from the distribution server 218). In some embodiments, both push and pull mechanisms may be involved. Once it receives the ticker data from the distribution server 218, the data can be buffered or cached (if appropriate), and processed for presentation on the display screen of the television set. In an embodiment, software in the client terminal 108 can use a ticker template to display the ticker data in the appropriate scrolling layout, format, locations, time intervals, and so forth.
  • This software in the client terminal 108 can also provide the user controllable PVR-like display features (such as fast forward, rewind, pause, skip, and the like), as well as process the corresponding operations that are performed by the user.
  • this software can comprise browser-based software or other software capable to cooperate with a web browser.

  • ticker data may be broadcast in one or more channel frequencies specifically dedicated for transmission of ticker data to client terminals 108.
  • the first tuner 300 can tune to a channel showing a television program, while the input interface 315 is tuned to receive ticker data (in the form of packets, for example) from a ticker channel to allow a ticker to be simultaneously shown on the same television screen as the television program.
  • the input interface 315 is an interface to receive outputs of recording devices such as a PVR or a digital video recorder (DVR) that may have ticker data stored therein, which may be received via download.

  • An embodiment of the client terminal 108 may include a processor 320 to control operation of the various components shown in Figure 3.
  • the processor 320 may work in conjunction with ticker software or other machine- readable instructions stored on at least one machine-readable storage medium 322.
  • ticker software may cooperate with the processor 320 to present ticker data in a ticker template or other screen interface or user interface, configure the format and layout of the ticker displayed on the display screen of the television, control the scroll speed of the ticker, process received user commands, perform the PVR- like operations of the ticker, obtain ticker data (and updates) from the distribution server 218, and other operations.
  • the ticker software can be pre-installed in the client terminal 108.
  • the ticker software may be installed by way of download from the system 100.
  • An audio and video output subsection 308 of the client terminal 108 receives decoded video and/or other applications (including ticker templates and the ticker data presented therein), and provides the decoded information to a television set.
  • a wireless interface 318 operates to receive commands from a user input device (such as a wireless remote control). Such commands can include the PVR-like commands to fast forward, slow motion, rewind or back up, pause, etc. the ticker. The wireless interface 318 provides these commands to the processor 320 so that the processor 320 can cooperate with the ticker software to perform the corresponding operation.
  • the storage medium 322 can also store user data 324 comprising user settings related to operation of the ticker.
  • the user data 324 can include explicitly saved settings for ticker speed, "learning mode" data collected from the user related to ticker speed and other playback features, which ticker categories to skip and which to pause, and so forth. This data can also be stored in other suitable locations in the system 100. In any of these storage locations, multiple sets of user data 324 may be stored, such as in implementations where multiple users in a household log into a same client terminal 108 and where each user may have different preferences as to how they wish to view a ticker.
  • the storage medium 322 can include cache(s), buffer(s), or other types of storage locations where ticker data may be stored. For example, received sports scores can be stored in the storage medium and retrieved during the appropriate times during the course of the scrolling of the ticker.
  • the ticker data stored in the storage medium 322 can be replaced as updates are received from the distribution server 218.
  • less time-dependent ticker information e.g., information that need not necessarily be updated several times per day
  • graphics for weather displays, game schedules, and the like can be downloaded to the storage medium 322 during non-peak television viewing periods (such as late at night), and then retrieved from the storage medium 322 when that piece of information is appropriate for presentation in the ticker.
  • ticker data can be retrieved from the storage medium 322 when the PVR-like operations are performed. For instance, when performing a rewind or back-up of the ticker, the previously displayed ticker information can be retrieved from a cache or buffer in the storage medium 322, and then re-displayed. When pausing the ticker, upcoming ticker data can be buffered in the storage medium 322 until the pause is released by the user. Because an embodiment of the ticker scrolls through a complete cycle before repeating, the ticker data can be stored in sequential locations in the storage medium 322 for subsequent playback, and these locations can be selectively accessed to obtain the data therein when performing a fast forward, skip ahead, or speed adjustment.
  • Figures 4-6 are television screen shots illustrating ticker operation according to various embodiments of the invention. For simplicity of explanation, not all of the possible PVR-like operations are depicted, as such other possible operations can be ascertained by examination of the operations specifically shown in Figures 4-6. Moreover, it is to be appreciated that the format, layout, direction, content, and other characteristics of the ticker shown in Figures 4-6 are merely illustrative and that variations are possible.
  • a television set 400 is coupled to the client terminal 108 in a manner that allows a display screen 402 of the television set to show a television program 404.
  • the television program 404 in this example is a video image of a basketball game.
  • a ticker 406 is shown scrolling across the bottom of the display screen 402.
  • the ticker 406 can be an overlay over the television program 404, or the television program 404 may be scaled appropriately on the display screen 402 to avoid the need for an overlay.
  • the ticker 406 is scrolling from right to left (as symbolically depicted by an arrow 408). It is to be appreciated that in other embodiments, the ticker 406 may be scrolling in different directions and may also be positioned differently on the display screen 402.
  • the ticker 406 is shown as being in a cycle when it is presenting sports scores (e.g., "Rams 3, Patriots 14" is the current ticker item that is being displayed under a "Sports" category tab 405) or other moving text items. There may be any suitable number of categories and subcategories through which the user can navigate via tabs 407.
  • the ticker 406 can be presented via use of ticker software that places received ticker data into a ticker template or other user interface.
  • a user input device such as a wireless remote control 410, is in communication with the client terminal 108 (via the wireless interface 318) to perform conventional television-viewing operations and also to control operation of the ticker 406 according to an embodiment of the invention.
  • the remote control 410 includes a numeric keypad 412 that the viewer can use to select television channels from a plurality of available television channels.
  • the remote control 410 can include a ticker button 414, which if pressed, causes a command to be sent to the client terminal 108 to instruct the ticker software to render the ticker 406 on the display screen 402. If the ticker button 414 is pressed again, the ticker 406 is taken off the display screen 402.
  • ticker 406 could be invoked and dismissed via a number of ways-such as by voice command(s), by gesture(s), by touching the ticker screen interface (e.g., touch- screen functionality), or by presence-detect (e.g., sensing a remote control being picked-up), among others. It is to be appreciated that the scope of the invention is not limited by the particular type of technique to invoke and dismiss the ticker 406.
  • the remote control includes arrow keys 416. Pressing these arrow keys 416 allows the user to change channels or volumes, navigate through categories and menus of the ticker 406, and perform other operations.
  • ticker speed control can be performed by holding down an appropriate one of the arrow keys 416.
  • the arrow keys 416 can operate analogously to a "gas pedal" for the ticker 406 ⁇ the scroll speed of the ticker 406 accelerates if the user holds down the "forward" arrow key. Once that key is released, the ticker 406 can return instantaneously to an initial speed or it can decelerate more gradually.
  • wireless commands sent from the remote control 410 to the client terminal 108 can be processed by the ticker software to detect that an arrow key is being held down and being released, thereby allowing the ticker software to perform the responsive ticker speed adjustment.
  • An embodiment of the remote control 410 can also include a plurality of buttons 418 similar in appearance to the fast forward, rewind, pause, slow motion, skip ahead, etc. buttons to control a PVR or other recording device. If the ticker 406 is active and if one of these buttons 418 is pressed, the corresponding command is sent to the client terminal 108. The ticker software in the client terminal 108 can interpret the command and then perform the appropriate PVR- like operation on the ticker 406.
  • buttons 420 for the PVR-like operations can be displayed on the display screen 402.
  • the user can navigate through these on-screen buttons 420 using the arrow keys 416.
  • Figure 5 illustrates a rewind or back-up operation. For instance, if a ticker item has scrolled too quickly or if the user wishes to view a previously displayed item again, the user can press one of the buttons 418 on the remote control 410.
  • the ticker 406 is rewound (shown symbolically by the arrow 408 being pointed in a different direction than as shown in Figure 4) so as to display a previously scrolled score 500 ("Bills 7, 49ers 10") that had scrolled out of view on the display screen 402, while an adjacent ticker item 502 ("Rams 3, Patriots 14" from Figure 4) is also "backed up" to the point that the score may not entirely appear on the display screen 402.
  • the user can rewind the ticker 406 back to any point, while a subsequent action (such as a button press to fast forward or "play”) stops the rewind and allows to the ticker 406 to scroll in the opposite direction.
  • Figure 6 illustrates a pause operation (depicted by the absence of the directional arrow 408 that symbolically shows movement of the ticker 406), in a manner that the user can choose to pause ticker items for extended viewing. For instance, the user can pause the ticker 406 so as to freeze the "Rams 3, Patriots 14" ticker item 502, while subsequent ticker items 600 are also paused or grayed out. While a ticker item is paused, the succeeding ticker items can be buffered and updated as needed prior to being displayed, such that when the ticker 406 resumes scrolling, the most recently updated ticker items will be scrolled.
  • ticker 406 will cycle through (and repeat presentation of) only that locked category, subcategory, or item, and will not cycle through non-locked categories, subcategories, or items. While cycling through locked components, the ticker 406 will scroll updated information, if available. Examples of techniques to perform locking are disclosed in U.S. Application Serial No. 10/091 ,364, entitled NAVIGATION IN AN INTERACTIVE TELEVISION TICKER, filed March 4, 2002, assigned to the same assignee as the present application, and incorporated herein by reference in its entirety.

  • a buffer 700 or other storage unit which can be located in the storage medium 322, receives ticker data from the distribution server 218. As described above, this ticker data can be tuned to via the first tuner 300, the second tuner 310, the input interface 315, or other component of the client terminal 108.
  • the buffer 700 can hold not only constantly changing (e.g., time-sensitive) ticker data, but also more static information such as graphics.

  • the buffer 710 is accessible by the user interface 704 via a link 712 to receive ticker items that have already been displayed, so that such data may be provided to the buffer 700 to be re-displayed in the next scrolling cycle of the ticker 406.
  • the link 712 is two-way in that if a rewind operation is performed, the software controller 706 can instruct the API 708 to retrieve the previously presented data from the buffer 710 and provide that data to the ticker template 704.
  • the buffers 700 and 710 comprise the same buffer, or a single data structure from which ticker data may be retrieved and replayed.

  • the command processing block 714 comprises part of the user interface 704, such that the viewer can view ticker data and enter commands related to that ticker data through the same interface. Once the particular command 716 is identified, that command is sent to the software controller 706 in one embodiment. In another embodiment, the command is sent from the user interface 704 to the API 708.
  • the software controller 706 can send the appropriate commands to the API 708 to increase the scroll speed of the ticker 406 and also ensure that data is fed from the buffer 700 to the ticker template 704 at the correct rate.
  • the software controller 706 can de-couple the buffer 700 from the ticker template 704, cause the buffer 710 to output its data (corresponding to the buffer locations when the receive command was received) to the user interface 704, and instruct the API 708 to reverse the direction of the ticker 406.

At least some of the elements of the flowchart 800 can be embodied in software or other machine-readable instruction stored in a machine-readable medium, such as at the client terminal 108 or remotely at a server. Moreover, it is appreciated that the various operations shown in the flowchart 800 need not necessarily occur in the exact order shown. Beginning at a block 802 ticker software, including upgrades or new components, are installed in the client terminal 108, for instance. In one embodiment, the ticker software can include some of the components shown in Figure 7, and may be factory installed or installed via download.

  • the download at the block 804 can occur during low-bandwidth-utilization hours (such as late at night), during commercial breaks, while the television set 400 is turned off, or other convenient times.
  • Ticker data is received at a block 806 via the techniques and communication paths described with reference to Figure 3.
  • ticker data is received, such as updated sports scores or weather reports.
  • the software controller 706 polls the distribution server 218 for new data, does a comparison to see if the new data should replace the existing data, and if so, passes the data to the API 708 so that the API 708 can instruct the user interface 704 to render the new data. If no new ticker data is received or if there is no new data, the previously received ticker data is scrolled at a block 808. New ticker data is rendered at a block 810, such as via the user interface 704. In an embodiment, the rendering at the block 810 is performed according to default settings for speed, direction, sequence, and the like. If user settings have been saved, the rendering at the block 810 is based on the applicable user settings.
  • ticker software (such as the user interface 704) identifies the specific action requested, and then provides the corresponding command to the software controller 706 or to the API 708 of Figure 7.

  • speed adjustments, user reaction times to perform a PVR-like action on scrolling ticker items, viewing habits or click history of the user, and the like can be saved or learned at the block 816.
  • the ticker software monitors whether the user wishes to resume to an original ticker presentation operation. For instance, after fast forwarding the ticker 406, the user can press one of the buttons 418 on the remote control 410 to return to the original ticker scrolling speed. Alternatively or in addition, the user can "let up on the gas pedal" by releasing one of the arrow buttons 416 being held down to speed up or slow down the ticker speed.
  • the flowchart 800 returns to the block 806 to determine if new ticker data has been received (which may be performed by the software controller 706 in one embodiment), so that the new data can be presented in the ticker 406 that resumes back to its original operation.

  • Programming for a DBS system may be distributed, for example, by multiple high- power satellites in geosynchronous orbit, each with multiple transponders. Compression (e.g., MPEG) is used to increase the amount of programming that can be transmitted in the available bandwidth.
  • a digital broadcast center e.g. , analogous to the head-end 106) may be used to gather programming content, ensure its digital quality, and transmit the signal up to the satellites.
  • Satellite-delivered programming is typically immediately digitized, encrypted and uplinked to the orbiting satellites. The satellites retransmit the signal back down to every earth-station-or, in other words, every compatible DBS system receiver dish at customers' homes and businesses.
  • Some programs may be recorded on digital videotape in the broadcast center to be broadcast later. Before any recorded programs are viewed by customers, technicians may use post-production equipment to view and analyze each tape to ensure audio and video quality. Tapes may then be loaded into a robotic tape handling system, and playback may be triggered by a computerized signal sent from a broadcast automation system. Back-up videotape playback equipment may ensure uninterrupted transmission when appropriate.

Abstract

Une bande (406) destinée à afficher des informations est utilisée (Fig. 5) dans un système de télévision interactive (100). Cette bande (406) a des fonctions d'affichage contrôlées par l'utilisateur, notamment avance rapide, rembobinage, contrôle de vitesse, saut, ralenti ou pause. Si le défilement d'un article d'intérêt a été trop rapide, l'utilisateur peut initier une opération de rembobinage pour visualiser l'article précédemment affiché au lieu d'attendre que la bande (406) ne réaffiche cet article lors du prochain cycle. Les opérations d'avance rapide ou de saut permettent à l'utilisateur d'accélérer dans la bande (406) les articles de moindre intérêt. Les opérations de ralenti ou de pause donnent à l'utilisateur suffisamment de temps pour visualiser un article dans toute sa longueur. Le contrôle de vitesse permet d'ajuster la vitesse de défilement de la bande (406). Les fonctions contrôlables par l'utilisateur sont exécutées de manière dynamique par l'utilisateur lors de la visualisation de la bande (406) et peuvent être facilement changées, comparé aux réglages statiques faits par un écran de configuration.
