ASSOCIATING WEB SITES TO TELEVISION PROGRAMS

Abstract: One type of home entertainment system, known as a PC-TV system, integrates televisions and computers into one system, allowing users to switch between using a video monitor to watch television programs or to support computer activities, like work processing or surfing the world wide web. Although the systems often include electronic program guides which help users sift through thousands of available television programs, these guides lack data about the thousands of on-line computer services, such as websites, that are available. Accordingly, the present invention provides a system and method that not only includes data about websites generally, but also allows users to logically relate this data to specific television programs. In one system embodiment, the system automtically displays a list of relevant websites for a given channel or program and gives the user the option to communicate with a website from the list. Thus, the present invention makes it much easier to manage and access the information available from on-line computer services.

Field of the Invention The present invention pertains to electronic program guides for televisions, particularly to electronic programming guides at include information about websites. Background of the Invention The home electronics industry, in the midst of an on-going convergence of televisions and computers, has produced a new class of products, known as PC-TV systems, or personal-computer-television systems. In their simplest form, these systems allow users to selectively switch between using a video monitor, or display, to watch television or to support computer activities, like word processing, creating spread sheets, playing computer games, or even surfing the world wide web. A seminal example, the Gateway Destination PC-TV system, from Gateway 2000, Inc., not only weds a television to a personal computer, but allows system expansion to receive programming from internal sources such as video-cassette recorders, laser-disc players, and video cameras and from external sources such as direct-broadcast-satellite receivers, etc. With the growth in the number of video channels, particularly cable and satellite television channels, many PC-TV systems now include an electronic program guide — a database listing available television channels and their program schedules. In these systems, the electronic program guide (EPG) operates as a user-prompted menu system, which logically organizes and displays thousands of program options. Typically, the user uses a wireless remote control both to prompt display of the EPG and to select a program for viewing or recording. The user may also update contents of the program guide by downloading data from a remote data source. Conventional EPGs, tailored for television systems, suffer from a common disadvantage which limits their usefulness in PC-TV systems. Specifically, they lack data about on-line computer services, such as websites, which are relevant to specific television or video programming. The failure of current EPGs to provide this data makes it awkward, and simply inconvenient, for users to access websites. For example, television broadcasters such as ABC, CBS, NBC, and FOX maintain websites which provide specific information about their respective television programs. Also, television advertisers commonly show website addresses during commercials, encouraging interested viewers to seek more information about their advertised products. However, typical televisions lack the capacity to link to websites, leaving many interested viewers with the unattractive alternative of getting up to use their computers. And even in PC-TV systems that allow concurrent PC and TV usage, linking to these websites is cumbersome because PC-TV users still have to invoke their Internet browser software and then enter the address of the website to gain access. In one limited solution, television broadcasters include their website address as part of the television signal, specifically within its vertical blanking interval (VBI) . In some PC -TV systems, this allows automatic or selective linking to the website. However, the approach is severely limited, not only because few broadcasters transmit their website addresses within the VBI and special hardware is needed to decode the addresses, but also because users have no control over what website addresses the broadcasters transmit. Accordingly, there is not only a need for a system that provides data about websites generally, but also a need for a system that relates this data to specific television programs. Summary of the Invention To address these and other shortcomings, the present invention provides a system and method that enables users not only to establish a database of websites or other computer services, but to adaptively relate these websites and computer services to specific television programs. Specifically, one system embodiment includes a receiver for receiving a sequence of scheduled programs; a database that relates data about a first website, or more broadly a computer service, to one scheduled program; and a display for displaying both the one scheduled program and the data about the first website. The data about the first website preferably includes a network address or telephone number for communicating with the first website, facilitating an option to communicate with the website while watching the television program. Another embodiment enables a user to enter or change the website data, and even to relate or associate the website data to other scheduled programs. This feature allows the user to continually update or adapt the database to personal preferences. Other embodiments and advantages of the invention will become apparent after considering the accompanying drawings and the following detailed description.

Detailed Description of the Preferred Embodiment The following detailed description, which references and incorporates Figures 1- 5, describes and illustrates specific embodiments of the invention. These embodiments, offered not to limit but only to exemplify and teach the invention, are shown and described in sufficient detail to enable those skilled in the art to practice the invention. Thus, where appropriate to avoid obscuring the invention, the description may omit certain information known to those of skill in the art. Figure 1 shows a PC-TV ( or convergence) system 100 with a novel database which not only includes data about on-line computer services or websites, but also relates this data to specific channels and programs. Specifically, PC-TV system 100, which preferably incorporates all features of the Destination PC-TV system from Gateway 2000, Inc. of North Sioux City, South Dakota, includes a monitor 110, a tuner- receiver 120, and a personal computer 130. Monitor 110, the heart of the system from a user perspective, displays video programming from tuner-receiver 120 or personal computer 130. Monitor 110 also includes built-in audio speakers (not shown) for outputting audible signals. In the preferred embodiment, the monitor provides a super- VGA display format. Tuner-receiver 120 receives audio or video or digital data signals via direct connection or wireless coupling to a multi-channel programming source. Each channel carries a scheduled sequence of programs, or programming events. In the preferred embodiment, tuner-receiver 120 accepts cable television signals, local over-the-air broadcast signals, and direct satellite television signals, which carry video, audio, or digital data. Personal computer 130, operatively coupled to monitor 1 10 and tuner-receiver 120, includes a processor 131, a local memory 132, a mass-data-storage device 133, a modem 134, a clock 135, and a set of user interface devices 136. Interface devices 136 include a keyboard 136A, a mouse or other pointing device 136B, and a microphone 136C, all of which support user interaction with a graphical user interface, preferably a version of Microsoft Windows. Mass-data-storage device 133, which preferably includes a hard drive, stores executable communications software 133 A, such as Netscape Navigator or Microsoft Internet Explorer, to communicate with remote computer systems, via the Internet or other computer network. When executed, this software causes computer 130 to operate a network communications device. Also, storage device 133 stores executable electronic program guide (EPG) software 133B, preferably Smart Guide software from Intel Corporation. This software allows program schedules to be updated through a direct-dial connection to a remote server. However, any functionally equivalent hardware, software, or firmware implementation of an electronic program guide will suffice. Additionally, storage device 133 stores an EPG database 133C and a computer- services database 133D. (Although these databases as shown and described as separate entities, databases 133C and 133D may be merged easily into a single comprehensive database.) EPG database 133C, which preferably contains programming schedules for most, if not all, currently-available cable and satellite television channels, cooperates with EPG software 133B to assist a user in finding and accessing relevant television programs. Figure 2 shows a preferred data structure of EPG database 133C. Computer-services database 133D logically relates information about a set of computer services, preferably networked computer services such as websites, to information about specific television channels or programs. In the preferred embodiment, database 133D includes a number of user-defined records, with each record corresponding to a computer service. Each record includes a computer-service identifier field which identifies the computer service, a communications data field which includes data, such as a URL address or telephone number, for linking to (or establishing communications with) the computer service, and a relational field which contains a set of program or channel identifiers. Figure 3 shows the preferred data structure of computer-services database 133D. Storage device 133 includes a computer-readable storage medium, for example a magnetic storage medium or electronic memory device, that stores executable, computer-service-guide software 133E which cooperates with monitor 110, tuner- receiver 120, computer 130, and computer-services database 133D to present users with options to link to computer services related to specific television channels or programs. Software 133E may operate within a broader software architecture which controls numerous other functions and services of PC-TV system 100. For example, the software may operate within the software architecture disclosed in co-pending patent application "Architecture for Convergence Systems," which has the same assignee and filing date as the present application and which is hereby incorporated by reference. When executed, computer-services-guide software 133E causes system 100 to operate according to the preferred method illustrated in Figure 4. The method begins first with a system initialization at step 200. Initialization entails establishing the content of EPG database 133C and computer-service database 133D, preferably as shown in respective Figures 2 and 3. At step 210, or start-up, a system user sets tuner-receiver 120 to receive a specific channel signal, which preferably carries a scheduled sequence of programs, or programming events, which monitor 110 displays. For example, the user may select channel 5 and receive a channel signal that carries a sequence of NBC television programs. Step 220 entails determining the current channel and the current program received by tuner-receiver 120. In the preferred embodiment, computer 130 determines or identifies the current tuner channel. Then, using the current tuner channel and the current time (including date) from clock 135, computer 130 searches EPG database 133C to determine the current program. For example, if the current channel is channel 5 (NBC), and the time is 8 o'clock on a Thursday (1997), searching EPG database 133C (as illustrated in Figure 2) identifies the program as "Seinfeld," or program identifier XYZ. Step 230 requires searching computer-services database 133D for references to the current program (or channel.) In the preferred embodiment, this entails searching the relational fields of the computer-service records for a program identifier matching the current program. Thus, for example, searching computer-services database 133D (as illustrated in Figure 3) yields three computer-services related to the current program, specifically www.Seinfeld.com, www.NBC.com, and www.comedy.com. At step 240, monitor 110 displays the search results, preferably automatically within a small foreground website window while continuing to display the current program in the background. (Other arrangements such as displaying the website window and television program within non-overlapping windows or as foreground windows on another background are equally feasible.) If the search results indicate the computer-service database includes no related computer-services, the display will provide a message stating this. For the Seinfeld example, monitor 1 10 would display a website window similar to the one in Figure 5. In step 250, the system prompts the system user to select a computer service from the results displayed in the website window. The user selects using one of the interface devices, such as keyboard 136A, pointing device 136B, or microphone 136C. The preferred embodiment provides an option to modify the contents of computer- services database 133D. In step 260, the system responds to the user selection of step 250. If the user has selected a computer service, step 263 attempts to link with the selected computer service via communications software 133 A and modem 134, using the communications data stored within the database record for the selected computer service. If linking is successful, at step 265, the system displays data from the computer service within the website window, allowing the system user to interact with the website or computer service while also watching the television program. If the user has elected to modify the contents of computer-services database 133D, the system, performing step 262, presents options to add a computer service record, to modify the relational datafield portion of an existing computer-service record, or to completely delete a computer-service record. So, if a new channel, program, or computer service becomes available or if an existing one becomes unavailable, the user can modify the database accordingly. In step 264, the system executes the selected modification option. The modification feature is particularly valuable because it allows the user to define and control the relevancy of websites or computer service to television programs. For instance, the user may decide that the website www.kellogs.com is relevant (or related) to the Seinfeld television program and add it to computer-services database 133D, with the appropriate program identifier in its relational field. On the other hand, the user may decide to delete a website or computer service previously related to the Seinfeld show. In step 270, the system waits for the program to change, for the system user to change a channel, (or for the system user to deliberately invoke the website window with a specific command.) In either case, the system returns to start-up step 210 and repeats the method using an updated channel and time. Conclusion The present invention, a system and method of associating websites or other online computer services, to specific programming, such as television programs, overcomes a substantial obstacle to the seamless integration of personal computers and televisions. In particular, the method and system enable users not only to establish a database of websites or other computer services, but to adaptively relate these websites and computer services to specific television programs. Ultimately, the invention gives television viewers easy "push-button" access to websites and computer services that adhere to their preferences, not someone elses. The embodiments described above are intended only to illustrate and teach one or more ways of practicing or implementing the present invention, not to restrict its breadth or scope.
