Abstract

A method and apparatus for generating an on-screen guide by which a user may select channels to view in a multiple channel broadcasting system are provided. According to one aspect of the invention, a program guide is generated comprising a number of still video pictures that represent current programming on a number of channels. The program guide is generated by the system tuning sequentially to each one of a number of channels. A visually usable video frame is captured from one of the number of channels. The visually usable video frame is then decimated. Each of the steps of tuning, capturing, and decimating are then repeated for each of a selected number of channels. Following generation, the program guide is displayed on a screen or display. A system pointer is displayed on the screen along with the program guide, and the system pointer is manipulated in response to input by the user. A channel is selected for viewing by manipulating the system pointer to an area associated with the still video picture of the corresponding channel.

Claims

1. In a multiple channel broadcasting system in which programs are broadcasted for display on a screen, a method for generating an on-screen guide for a user to select channels to view, comprising the steps of:

generating a program guide comprising a plurality of still video pictures representing current programming on a plurality of channels, wherein the step of generating a program guide comprises the steps of,

tuning sequentially to each one of the plurality of channels,

capturing a visually usable video frame from the one of the plurality of channels,

decimating the visually usable video frame;

displaying the program guide on a screen;

displaying a system pointer that is manipulated in response to input by the user; and

selecting a channel for viewing using the system pointer manipulated to an area associated with the still video picture of the channel.

2. The method of claim 1, wherein the steps of tuning, capturing, and decimating are repeated for each of the plurality of channels.

3. The method of claim 1, wherein the visually usable video frame is the Intra frame (I frame) in a Motion Picture Experts Group-2 (MPEG-2) bit stream.

4. The method of claim 1, wherein the step of decimating the visually usable video frame comprises filtering and decimating the Intra frame (I frame).

5. The method of claim 1, wherein the step of decimating the visually usable video frame provides a video frame that is one-fourth of the pixel dimensions of the visually usable video frame.

6. The method of claim 1, further comprising the step of manipulating the system pointer among areas of the program guide associated with each of the plurality of still video pictures.

7. The method of claim 1, further comprising the steps of:

refreshing the decimated visually usable video frame, the refreshing occurring sequentially for the plurality of channels; and

storing the refreshed video frame in a memory.

8. The method of claim 1, further comprising the step of selecting a plurality of channels for inclusion in the program guide from a plurality of channels broadcasted by the multiple channel broadcasting system.

9. The method of claim 8, wherein the program guide comprises nine still video pictures representing nine channels, the nine channels selected by using an on-screen menu.

10. The method of claim 1, further comprising the step of displaying corresponding channel and program information with each of the plurality of still video pictures.

11. A computer system comprising a processor configured to be coupled to a display device, said processor:

configured to generate a program guide comprising a plurality of still video pictures representing current programming on a plurality of channels, wherein the processor is configured to generate a program guide by being further configured to,

tune sequentially to each one of the plurality of channels,

capture a visually usable video frame from the one of the plurality of channels, the visually usable video frame being the Intra frame (I frame) in a Motion Picture Experts Group-2 (MPEG-2) bit stream,

filter and decimate the visually usable video frame, and

store the decimated visually usable video frame for display;

configured to display the program guide on a screen;

configured to display a system pointer that is manipulated in response to input by the user; and

configured to select a channel for viewing using the system pointer manipulated to an area associated with the still video picture of the channel.

12. The computer system of claim 11, wherein the processor is configured to capture, filter, decimate, and store after tuning sequentially to each of the plurality of channels.

13. The computer system of claim 11, wherein the processor is further configured to manipulate the system pointer among areas of the program guide associated with each of the plurality of still video pictures.

14. The computer system of claim 11, wherein the processor is configured to generate a program guide by being further configured to:

refresh the decimated visually usable video frame, the refreshing occurring sequentially for the plurality of channels; and

store the refreshed video frame in a memory.

15. The computer system of claim 11, wherein the processor is further configured to control the selection of a plurality of channels for inclusion in the program guide.

16. A system for generating an on-screen guide for a user to select channels to view in a multiple channel broadcasting system in which programs are broadcasted for display on a screen, comprising:

a program guide comprising a plurality of still video pictures representing current programming on a plurality of channels, wherein the program guide is generated by,

tuning sequentially to each one of the plurality of channels,

capturing a visually usable video frame from the each one of the plurality of channels, the visually usable video frame being the Intra frame (I frame) in a Motion Picture Experts Group-2 (MPEG-2) bit stream,

decimating the visually usable video frame,

refreshing the decimated visually usable video frame,

storing the decimated visually usable video frame;

a screen for display of the program guide;

a system pointer that is manipulated in response to input by the user; and

a channel selected for viewing using the system pointer manipulated to an area associated with the still video picture of the channel.

17. The system of claim 16, wherein the system pointer is manipulated among areas of the program guide associated with each of the plurality of still video pictures.

18. The system of claim 16, wherein a plurality of channels are selected for inclusion in the program guide from a plurality of channels broadcasted by the multiple channel broadcasting system.

19. A computer readable medium containing executable instructions which, when executed in a processing system, causes the system to perform the steps for generating an on-screen guide for a user to select channels to view in a multiple channel broadcasting system comprising:

generating a program guide comprising a plurality of still video pictures representing current programming on a plurality of channels, wherein the generating a program guide further causes the system to perform the steps of,

tuning sequentially to each one of the plurality of channels,

capturing a visually usable video frame from the each one of the plurality of channels, the visually usable video frame being the Intra frame (I frame) in a Motion Picture Experts Group-2 (MPEG-2) bit stream,

decimating the visually usable video frame;

displaying the program guide;

displaying a system pointer that is manipulated in response to input by the user; and

selecting a channel for viewing using the system pointer manipulated to an area associated with the still video picture of the channel.

20. The computer readable medium of claim 19, further causing the system to perform the step of manipulating the system pointer among areas of the program guide associated with each of the plurality of still video pictures.

21. The computer readable medium of claim 19, further causing the system to perform the steps of:

refreshing the decimated visually usable video frame, the refreshing occurring sequentially for the plurality of channels; and

storing the refreshed video frame in a memory.

22. The computer readable medium of claim 19, further causing the system to control selecting a plurality of channels for inclusion in the program guide.
