TECHNICAL FIELD

The invention relates generally to schedules for programming information and, more specifically, to a system for retrieving and displaying programming information in response to selection of a category of programming information.

BACKGROUND OF THE INVENTION

A national information infrastructure constructed from both wireless and wired communications networks supports the communication of information in homes and businesses throughout the country. Telephones, televisions, radios, computers, and facsimile machines are used each day to receive, store, process, perform, display, and transmit data, text, voice, sound, and graphic images. These devices are typically connected via fiber optic cables, coaxial cables, electronic switches and routers, microwave networks, satellites, and other communications technologies. This national information infrastructure, which may one day be expanded to a global infrastructure, supports the electronic transfer of a wide variety of programming to entertain, instruct, or inform receiving parties. In view of both the variety and the substantial amount of available programming, a user typically uses a programming schedule or guide to select a desired program for reception (or transmission) on a certain date and time.

For example, a subscriber to cable network programming services, such as premium cable television or audio services, typically uses a printed schedule to select a program for viewing or listening to at a certain time period. In addition, certain cable television services supply the viewer with an on-screen programming schedule from the headend processor via the able distribution network. For both printed and on-screen programming schedules, the programming information is typically presented as a function of the date and time for the scheduled programs. Thus, if the subscriber is interested in viewing a sports-related program, it is necessary for the subscriber to review the time periods for that date to determine if a sports-related program is scheduled during the viewing period. This time-based presentation of programming schedule information is satisfactory only when the amount of available programming is relatively limited. Furthermore, unlike the printed programming schedule, the user typically cannot control the order of the programming information supplied by an on-screen programming schedule because this information is supplied from a remote location via a conventional one-way cable distribution network.

In view of the advances in computing and broadband communications systems, it is expected that the present information infrastructure will evolve into an integrated communications network supported by advanced high-speed, interactive, broadband, digital communications equipment. Telephones, televisions, radios, computers, and facsimile machines will be linked by this interactive broadband information intrastructure and will be able to communicate and interact with other communication devices in a digital signal format. This interactive broadband information infrastructure, commonly referred to as the "information superhighway," has great potential to increase access to information and entertainment resources that can be delivered quickly and economically anywhere in the country. For example, it is feasible that hundreds of channels of "television" programming, thousands of audio recordings, and literally millions of "magazines" and "books" can be made available to homes and businesses via this information superhighway. In view of this tremendous expansion of available programming, the use of a programming schedule or guide will be critical for a user to select a desired program. However, as choices of programming increase, the prior time-based format of programming schedules becomes a less manageable technique for choosing a desired program because of the numerous programs available for any one time period. Thus, there is a need for a category-based programming schedule to clarify and to simplify for an audience the process of selecting programs of interest to each audience member.

The present invention supplies a system of retrieving and displaying a schedule for programming based primarily upon the classes of programs, rather than the time period for each program. The programming information displayed by this system is restricted to those programs matching characteristics selected by the viewer. This permits the viewer to narrow the scope of programming information supplied by the system to a more manageable number of choices and enables the viewer to have personal control over the displayed programming information. The present invention also provides a highly intuitive user interface to support the easy and convenient selection of desired programming information.

SUMMARY OF THE INVENTION

The present invention fulfills the above-described needs by providing a system for presenting programming information in an efficient and user-friendly manner based upon the classes of scheduled programs. This allows a user to view programming information by genre groupings rather than by a time-based schedule, thereby affording the user the opportunity to obtain information about a desired program from a substantial listing of available programs. The programming schedule can be presented as a display on a display device, such as a television or a computer monitor. The user can control the displayed programming information by selecting the category for the desired program, thereby updating the displayed programming information to match the viewer's selection. The selection of programming information can be controlled remotely via a remote control unit or directly by another input device, such as a keypad or a touch-sensitive screen.

Generally described, the system for retrieving and displaying programming information, i.e., the programming guide system, presents scheduling information for programs via a schedule display having three display elements, a category display, a subcategory display, and a program display. The category display displays an array of category tiles representing categories of programming information. The subcategory display displays an array of subcategory tiles representing subcategories that are associated with the categories of the category display. The program display displays an array of program tiles representing programs that are associated with the subcategories of the subcategory display.

To allow the user to easily view the tiles of each of the displays, the displays can be located adjacent to each other. A viewing panel can extend along a portion of each of the displays for displaying one each of the category, subcategory, and program tiles. In this manner, the viewer is presented with selected programming information divided into three separate classes, namely broad, mid, and narrow-scope classes of programming information.

A category of programming information can be selected by moving a corresponding category tile within the viewing panel. In response, the subcategory display displays a subcategory tile representing the subcategory associated with the selected category. This narrows the scope of displayed programming information by supplying subcategory information that is relevant to the selected category.

Likewise a subcategory of programming information can be selected by moving the corresponding subcategory tile within the viewing panel. In response, the program display displays one or more program tiles representing programs associated with the selected subcategory. This further narrows the scope of displayed scheduling information to the level of individual programs. The program tiles representing these programs can be ordered chronologically to supply the viewer with a time-based view of programs associated with the selected subcategory and the selected category.

The programming information is stored within one or more databases and is retrievable to support the display of selected programming information by the display system. Specifically, the category tiles, subcategory tiles, and program tiles are stored within a database structure on a memory storage device and can be retrieved as required to support the display of programming information represented by these tiles. Thus, at least one of the subcategory tiles representing a subcategory associated with a selected category is retrieved from the database in response to a selected category tile appearing within the viewing panel. In response to a selected subcategory tile appearing within the viewing panel, at least one program tile representing a program associated with the selected subcategory is retrieved from the database if a program is available that is associated with the selected subcategory.

More particularly described, the user can peruse a selected class of programming information by scrolling the tiles of one of the category, subcategory, or program displays. To control the display of one of the category, subcategory, or program tiles, the user can move a focus frame along the viewing panel to a location proximate to the selected corresponding display. The focus frame operates to highlight information supplied by the tile selected by the user by "framing" the tile, and supplies a visual cue to the user that the display associated with the framed tile can be controlled. For example, to control the category display, the user moves the focus frame along the viewing panel to a position on the category display. Upon positioning the focus frame over the category display, the category tile appearing within the viewing panel also appears within the focus frame. Thus, the focus frame extends along the boundary of the selected category tile. For this position of the focus frame, the viewer can scroll in a selected direction the category tiles, thereby supporting the selection of another category tile for viewing within the viewing panel (and the focus frame). Similar to the representative example of the category display, each of the subcategory and program displays can be controlled by placing the focus frame proximate to the respective display and thereafter scrolling through the tiles representing the selected programming information.

A remote control unit, such as an infrared transmitting device, can be used to transmit commands for controlling the programming information displayed by the category, subcategory, and program displays. Specifically, the position of the focus frame can be changed or the tiles of a selected display can be scrolled by outputting appropriate directional instructions via the remote control unit, thereby allowing the viewer to navigate the sources of programming information. However, other types of input devices also can be used to control the category, subcategory, and program displays, including a direct-wired keypad or a touch-sensitive screen.

Each of the program tiles can include text-based and/or graphical information regarding the represented program, including name, program date and start-time, and program channel. In addition, a program tile can list the network responsible for supplying the program, including the logo or symbol for the responsible network. Another option for program tiles is the use of graphic images, such as information icons, to represent secondary program information, including the items of closed captioning, audience rating, awards, star rating, or rerun status. The use of information icons on a program tile reduces the amount of text displayed on the screen, which, in turn, makes it easier to locate and read program titles or names.

For another aspect of the present invention, the program display can include date tiles representing calendar dates to separate the time-sorted program tiles, thereby eliminating any requirement of supplying date-related information for each program tile. Each date tile can separate program tiles associated with one date from program tiles associated with another date. In this manner, the program tiles in the corresponding programs are grouped by both date and time. The program display also can include a date status indicator that displays the date associated with the presently displayed program tiles.

Accordingly, it is an object of the present invention to provide a system for retrieving and displaying programming information based upon the categories of the programming information.

It is a further object of the present invention to provide a system for retrieving and displaying a schedule for programming in response to program characteristics selected by the user.

It is a further object of the present invention to provide a system for retrieving and displaying programming information that allows the user to narrow the scope of displayed programming information to a more manageable number of program choices.

It is a further object of the present invention to provide a highly intuitive user interface for a programming guide system to support a simple and convenient selection of desired programming information.

The attainment of the foregoing and related objects, advantages, and features of the present invention will be more readily apparent after review of the detailed description to follow and the appended drawings.

DETAILED DESCRIPTION

The present invention is directed to a system for retrieving and displaying programming information, thereby providing a user with a schedule or guide of available programs. Although the preferred embodiment of the present invention will be described with respect to interactive and broadcast television programming, those skilled in the art will recognize that the present invention can be used with other forms of programming information, including radio, broadcast print, audio, games, computer software, and other combinations of audio/video or software information. Accordingly, it will be understood that programming information generally includes information for programs transmitted electronically to entertain, instruct, or inform the recipient.

Turning now to the drawings, in which like numerals indicate like elements throughout the several figures, FIG. 1 illustrates the operating environment for the program schedule system 10. A memory storage device 12, such as a hard disk drive or an optical storage system, stores programming information in a digital format. This programming information can be supplied for the benefit of one or more subscribers to communications services responsible for the origination or distribution of programs associated with this programming information. One or more databases for various classes of programming information are maintained on the memory storage device 12.

For programming information related to television programs, the preferred database structure includes at least four tables, namely (1) a table containing records for each television episode, (2) a table containing records for each television series, (3) a table containing records of program categories, and (4) a table containing records of program subcategories. Each television episode is linked to its parent television series and each television series is associated with categories and subcategories which define the characteristics of the series. These categories and subcategories are respectively represented by the program category table and the program subcategory table, which are linked to records for the television series table by another table, the junction table. The junction table allows a one-to-many relationship, thereby supporting the classification of television programs under more than one category or subcategory.

To support the distribution of the programming information to each of the subscribers, the memory storage device 12 is connected to a headend processor 14 via a server 16. A conductive path 18 supplies a two-way communications link between the memory storage device 12 and the server 16. Likewise, a conductive path 20 supplies a two-way communications link between the headend processor 14 and the server 16. For the preferred embodiment, the server 16, in combination with the conductive paths 18 and 20, form a local area network that enables the headend processor 14 to interact with any other device on this network, including the memory storage device 12. The server 16 can be implemented by a computer running administrative software that controls access to the devices connected to the network.

To support the tasks of updating or revising the program information stored on the memory storage device 12, a computer workstation 24 and a server 22 are connected to the server 16 via a communications link 26. This communications link allows a program distributor or supplier, which typically operates at a location remote from the databases stored within the memory storage device 12, to transmit programming information for storage by the memory storage device 12 and eventual distribution to subscribers via the headend processor 14. The communications link 26 can be implemented by either a wireless or wired communications system. For example, the communications link 26 can be constructed as a microwave link or as a conventional telephone link.

The headend processor 14 operates to control the distribution of programming information stored on the memory storage device 12 and the associated programs to one or more subscribers of associated programming services. The headend processor 14 is connected to each of the subscribers via a cable distribution network 28. The cable distribution network 28 is preferably implemented as an interactive communications network. This supports delivery of programming information and programs via the headend processor 14 to the subscriber and the delivery of requests for programming information and programs by the subscriber to the headend processor 14. The cable distribution network 28 can be implemented by a microwave distribution system, a telephone system, coaxial or optical cables, or any combination of these delivery systems. The headend processor 14 also can support the distribution of programs associated with the programming information to the subscribers and support other services via a separate distribution network 29.

Those persons skilled in the art will appreciate that the programs delivered over the cable distribution network 28 typically comprise both video and audio signals. Programs can be delivered in digital format, analog format, or a combination of both analog and digital formats. However, for the preferred embodiment, the programs are delivered as a stream of digital video and audio signals. Likewise, programming information supplied to subscribers and requests or instructions issued by subscribers are preferably digital format signals.

Each subscriber is connected to the cable distribution network 28 via a cable 30 supplied to a set-top converter 32. The cable 30 is preferably implemented as either a coaxial cable or a fiber optic cable. In this manner, the subscriber "taps" into the cable distribution network 28 to (1) receive programs and programming information distributed by the headend processor 14 and to (2) transmit requests or instructions to the headend processor 14.

The set-top converter 32 accepts the programs and the programming information from the cable 30 and converts these signals to a format compatible for presentation by a receiving device 34, such as a television or a computer system. The set-top converter 32 is connected to the receiving device 34 via a conductive path 36. The receiving device 34 preferably includes a display 38 for displaying both programs and programming information. In particular, the programming information is supplied to the subscriber as a program schedule or guide via the display 38.

Selected operating functions of the set-top converter 32 can be remotely controlled by a remote control unit 40. The subscriber can use the remote control unit 40 to select for viewing certain characteristics of alternative user interfaces supplied by the schedule display, as described in more detail below with respect to FIGS. 2-4 and 6-8. The preferred remote control unit 40 is more fully described with respect to FIG. 5.

Generally, the instructions transmitted by the remote control unit 40 are received by the set-top converter 32 and, in response, one or more of the characteristics of the program schedule can be controlled to display the desired programming information to the subscriber. In particular, the set-top converter 32 receives certain instructions from the remote control unit 40 and, in turn, forwards these instructions to the headend processor 14 via the cable 30 and the cable distribution network 28. The headend processor 14 responds by retrieving selected programming information from the memory storage device 12 and transmitting the selected programming information via the return path provided by the cable distribution network 28 and the cable 30. The set-top converter 32 then supplies this programming information to update the schedule display presented by the display 38.

FIG. 2 is a diagram illustrating the preferred presentation of programming information by a schedule display 50. Referring to FIG. 2, the schedule display 50 includes three display elements, a category display 52, a subcategory display 54, and a program display 56. Each of the displays 52, 54, and 56 display separate classes of programming information. Specifically, the category display 52 displays various categories of programming information, such as "Animated," "Children," "Game Show," and so forth. Likewise, the subcategory display displays subcategories of programming information that are associated with the categories offered by the category display 52. For example, subcategories for the "Animated" category can include "Adventure," "Children," or "Martial Arts." Thus, in comparison to the category display 52, the subcategory display 54 displays a more narrow scope of programming information.

The program display 56 displays program items that are associated with the subcategories offered by the subcategory display 54. Thus, the program display 56 supplies programming information that is narrower in scope than either the subcategories of the subcategory-display 54 or the categories of category display 52. For example, the program display 56 presents program-specific information, such as program title, program start-time, and program channel. Each of these program items represents an actual program that can be viewed by the subscriber at a certain date and time.

As shown in FIG. 2, the displays 52, 54, and 56 are located adjacent to each other and the subcategory display 54 is sandwiched between the category display 52 and the program display 56. A viewing panel 58 spans the width of the schedule display 50 by extending along a portion of each of the displays 52, 54, and 56. For the preferred embodiment, the viewing panel 58 is mounted in a fixed location on the central portion of the schedule display 50. In contrast, a focus frame 60, which moves along a horizontal track of the viewing panel 58, can be positioned proximate to any one of the displays 52, 54, and 56. The viewing panel 58 focuses the subscriber's attention on a selected category, subcategory, and program. In contrast, the focus frame 60 serves to focus the user's attention upon a particular class of selected programming information and operates as an indication that the subscriber can control the programming information supplied by an associated display.

Programming information is presented by each of the displays 52, 54, and 56 via tiles, wherein each tile represents a specific item of programming information. The category display 52 includes category tiles 62 representing categories; the subcategory display 54 includes subcategory tiles 64 representing subcategories; and the program display 56 includes program tiles 66 representing programs. The category tiles 62 and the subcategory tiles 64 are preferably arranged in alphabetical order for the represented categories and subcategories. In contrast, the program tiles 66 are preferably chronologically-ordered based upon both the dates and start times of the represented programs.

The visible portion for each of the displays 52, 54, and 56, i.e., the display panel, may reflect only a subset of the entire list of programming items represented by tiles. Accordingly, tiles which are not immediately visible to the subscriber can be accessed by scrolling the display in a selected vertical direction. By moving the tiles of the selected display in either an up or down direction, previously hidden tiles are revealed in one direction and previously visible tiles are obscured in the other direction. For example, the subcategory tiles 64 of the subcategory display 54 will wrap from beginning to end unless there are less than four items of programming information for the selected subcategory. Thus, each of the displays 52, 54, and 56 can be viewed as a vertically spinning dial of tiles that supply programming information.

To "spin" one of the displays 52, 54, or 56, the focus frame 60 is moved along the viewing panel 58 to one of the displays. When the focus frame 60 is located proximate to the selected display, the subscriber has the option of scrolling up or down to reveal additional tiles. For the schedule display 50 shown in FIG. 2, the focus frame 60 is located proximate to the category display 52, thereby allowing the subscriber to scroll the category tiles 62 representing categories of programming information. FIGS. 3 and 4 respectively show the focus frame 60 located proximate to the subcategory display 54 and the program display 56, thereby allowing the subscriber to control the items presented by these displays. For the preferred schedule display 50, each of the displays 52, 54, and 56 uses three-dimensional shading to indicate that a tile is scrolling off beyond the visible area of its display.

As shown in FIGS. 2-4, arrow tabs 67 can be appended to the sides of the focus frame 60 to supply the subscriber with an indication of (1) the direction(s) that the focus frame 60 can move along the viewing panel 58, and (2) the directions that the subscriber can scroll the tiles of the selected display. For the schedule display 50 illustrated in FIG. 2, an arrow tab 67 is appended to the right hand side of the focus frame 60 to supply the subscriber with an indication that the focus frame 60 can be moved to either the subcategory display 54 or the program display 56. For this position of the focus frame 60, arrow tabs 67 also can be appended to the top and bottom sides of the focus frame 60 to alert the subscriber that the category display 52 can be scrolled in the up direction or the down direction.

For the focus frame 60 located proximate to the subcategory display 54 in FIG. 3, an arrow tab 67 can be appended to each of the four sides of the focus frame 60, thereby advising the subscriber that the focus frame 60 can be moved in a horizontal direction to either the category display 52 or the program display 56, and that the subcategory display 54 can be scrolled in either the up direction or the down direction. Likewise, for the focus frame 60 located proximate to the program display 56 shown in FIG. 4, the focus frame 60 can include an arrow tab 67 located on the left hand side of the frame and arrow tabs 67 located on the top and bottom sides of the frame. The positioning of these arrow tabs 67 indicate that the subscriber can move the focus frame 60 along the viewing panel 58 to either the subcategory display 54 or the category display 52, or scroll the program tiles in a selected vertical direction.

FIG. 5 is an illustration of the face of a remote control unit for controlling selected features of the schedule display. Referring now to FIGS. 1, 2 and 5, the remote control unit 40 can transmit instructions to the set-top converter 32 to allow the subscriber to (1) move the focus frame 60 to one of the displays 52, 54, or 56, and (2) scroll the tiles of the selected display. The face of the remote control unit 40 includes a control button 70 having navigation keys 70a-d for inputting commands to control features of the schedule display 50. This control button 70 is preferably implemented as a rocker-type switch which can operated in four distinct positions represented by the navigation keys 70a-d. Navigation keys 70b and 70d control the position of the focus frame 60 along the viewing panel 58 and navigation keys 70a and 70c control the scrolling operations of the displays 52, 54, and 56. Specifically, by pressing the navigation key 70b, the remote control unit 40 transmits a command to move the focus frame 60 to the right. In similar fashion, user selection of the navigation key 70d initiates a transmission of a command to move the focus frame 60 to the left. Navigation key 70a allows the subscriber to move the tiles of the selected display in an up direction, whereas navigation key 70c moves the tiles of the selected display in a down direction. The navigation keys 70a-d are preferably shaped in the form of an arrow to define the directional control functions associated with these command keys. The remote control unit 40 can include additional keys or buttons for inputting commands to control other operations of the set-top converter 32 or the receiving device 34.

In response to a command input by one of the navigation keys 70a-d, the remote control unit 40 transmits an instruction to the set-top converter 32 via an infrared communications link. In turn, the set-top converter 32 decodes the instruction and responds by controlling the selected feature of the schedule display 50. Specifically, the set-top converter 32, which converts the programs' and programming information delivered by the cable distribution network 28 for presentation via the display 38, can control each of the displays 52, 54, and 56 and the position of the focus frame 60 on the viewing panel 58. In addition, the set-top converter 32 can update the programming information presented by the schedule display 50 by outputting a request to the headend processor 14 via the return path supplied by the cable distribution network 28. This allows the retrieval of desired programming information from the memory storage device 12 containing the database which maintains program guide data.

Returning now to FIGS. 1-4, the subscriber typically selects programming information by first choosing the general category for the desired programming information. By moving the focus frame 60 to the category display 52, the subscriber can select a category of programming information by scrolling the category display 52 until the category tile 62 representing the desired category appears within the viewing panel 58. By scrolling the category tiles 62 in a selected vertical direction, each category tile sequentially appears within the viewing panel 58. A category is selected when its corresponding category tile 62 appears within the frame of the viewing panel 58. In turn, this "resets" the subcategory display 54 to display subcategory tiles 64 representing subcategories associated with the selected category. The program display 56 responds to the appearance of a selected subcategory tile 64 within the viewing panel 58 by displaying one or more program tiles 66 representing programs associated with the selected subcategory if such programs are available for the selected subcategory. Thus, the viewing panel 58 can display tiles representing the selected category, subcategory, and program.

In response to the selection of a new category of programming information, the set-top converter 32 outputs a request to the headend processor 14 for programming information representing subcategories associated with the selected category. The subcategory display 54 is reset by the setup converter 32 in response to receiving the requested subcategory items over the cable distribution network 28. Likewise, in response to the selection of a subcategory item, the set-top converter 32 outputs a request for programming information representing programs associated with the selected subcategory. If a program is available which corresponds to the selected subcategory a
