Abstract

A program time guide for an interactive viewing system allows a user to control the time and channels for which program information is displayed. The user can navigate through the program time guide to identify and select desired programs. The program time guide displays information for various types and sources of programming by assigning each program source a channel number. Selecting a program on a particular channel causes the system to tune to an associated frequency to receive video signals, launch a computer executed application which generates displayed information, or to perform some other activity associated with that channel or program.

Claims

1. In an interactive viewing system having a head end in two-way communication with a plurality of viewer stations having a video display operatively coupled to a controller, the head end providing to the viewer stations programming comprising a plurality of programs, the head end storing program schedule information identifying for the plurality of programs a time at which the program is available and a channel on which the program is available, the controller of at least one viewer station being capable of storing at least a portion of the program schedule information at the controller, a method of providing a user with program schedule information, the method comprising the steps of:

receiving at a controller a request from a user for program schedule information;

determining whether the requested program schedule information is stored at the controller;

in the case of a negative determination, communicating the request from the controller to the head end; and

retrieving the requested program schedule information from the head end

in the case of a positive determination, retrieving the requested program schedule information at the controller; and

displaying a display of the requested program schedule information on a video display.

2. The method of claim 1 in which the display comprises:

a grid having channels displayed along one axis and time along another axis;

a plurality of program tiles, each program tile corresponding to a program, the program tiles positioned within the grid at the intersection of the channel on which corresponding program is available and the time at which the corresponding program is available; and

a focus frame identifying one of said program tiles.

3. The method of claim 2 in which the focus frame can be moved in response to a user'"'"'s command to selectively identify a selected program tile, the command being input to the controller with an input device.

4. The method of claim 3 in which the user can move the focus frame to select a time and channel for which program schedule information is displayed.

5. The method of claim 4 in which at least one of the program tiles corresponds to a program that is a computer executed application.

6. The method of claim 5 in which time is displayed on a horizontal axis of the grid and channels are displayed along a vertical axis of the grid.

7. The method of claim 5 in which time is displayed along a vertical axis of the grid and channels are displayed along a horizontal axis of the grid.

8. The method of claim 4 in which the size of the program tile corresponds to the length in time of the corresponding program.

9. The method of claim 8 in which a program tile that is too large to be completely displayed within the grid is provided with an indicator to indicate that the program tile is only partially displayed.

10. The method of claim 2 in which program tiles corresponding to currently available programs are displayed in a visually distinct manner from program tiles corresponding to currently unavailable programs.

11. The method of claim 10 in which program tiles corresponding to currently available programs are displayed in a first color and program tiles corresponding to currently unavailable programs are displayed in a second color.

12. The method of claim 2 in which the grid defines vertical columns and horizontal rows, each column being associated with a particular time period and each row being associated with a particular channel, the program tiles capable of spanning more than one column to represent a program with a length greater than the time period, and in which a user can move the focus frame vertically by entering a first command and horizontally by entering a second command, vertical movement of the focus frame being tied to an anchor column, the anchor column being changeable by a user inputting the second command.

13. An interactive system for providing program scheduling information to the user of an interactive program viewing system having a central head end in bidirectional communication with multiple viewer stations that include a video display operably coupled to a controller and an input device for inputting commands to the controller, the head end delivering a plurality of programs at different times over a plurality of channels to the plurality of viewer stations, the system comprising:

a first memory located at the head end for storing program schedule information, the program schedule information identifying for the plurality of programs a time at which the program is available and a channel on which the program is available;

a second memory located at a controller for storing a portion of the program schedule information stored at the head end;

the controller operative, in response to a command input through the input device, to generate a display of a selected first portion of the program schedule information on the video display, the selected first portion including program schedule information for at least two of the plurality of programs, the selected first portion being determined by a user of the system, wherein if the selected first portion is not stored in the second memory the controller retrieves the selected first portion from the first memory for display.

14. The system of claim 13 wherein the display includes a grid having time along a first axis and channels along a second axis.

15. The system of claim 14 in which the plurality of programs included within the selected first portion of program schedule information are each represented by a program tile positioned within the grid at the intersection of the times at which the program is available and the channel on which the program is available.

16. The system of claim 15 further comprising a focus frame which identifies one of the program tiles.

17. The system of claim 16 in which the focus frame can be moved within the grid to selectively identify one of the program tiles.

18. The system of claim 17 in which the focus frame can be moved to select a second selected portion of the program schedule information, the second selected portion being displayed in place of the first selected portion in the display.

19. The system of claim 18 wherein the controller obtains at least part of the second selected portion from the first memory.

20. In an interactive viewing system having a head end in two-way communication with multiple viewer stations having a video display operably coupled to a controller and an input device for inputting commands to the controller, the head end delivering a plurality of programs at different times over a plurality of channels to the multiple viewer stations, the system comprising:

a first memory located at the head end for storing program schedule information said program schedule information identifying for the plurality of programs a time at which the program is available and a channel on which the program is available; and

a second memory located at the controller for storing a portion of the program schedule information stored at the head end,

the controller operative, in response to a user command input through the input device, to generate a display of program schedule information on the video display, the display comprising;

a grid with a plurality of times along a first axis and a plurality of channels along a second axis;

a plurality of program tiles, each associated with a program, positioned within the grid at the junction of the time at which the program is available and the channel on which the program is available; and

a focus frame indicating a selected program tile, the focus frame being movable in response to commands input through the input device to allow user selection of the times and channels for which program schedule information is displayed, wherein the controller obtains the program schedule information for the display from the first memory if it is not stored in the second memory.

21. In a controller for an interactive viewing system having a head end in two-way communication with multiple viewer stations having a video display operably coupled to the controller and an input device for inputting commands to the controller, the head end delivering a plurality of programs at different times over a plurality of channels to the multiple viewer stations, the head end comprising a first memory located at the head end for storing program schedule information said program schedule information identifying for the plurality of programs a time at which the program is available and a channel on which the program is available, the system comprising:

a second memory located at the controller for storing a portion of the program schedule information stored at the head end,
