Abstract

A method and apparatus that automatically scales the channel display area (i.e., thumbnails of the channels) based on the number of channels and displaying characteristics and that provides the user with options to customize the plurality of channels displayed in the multi-channel display is accomplished by determining whether all of the channels in the user'"'"'s customized list can be displayed within the given display area, which may be the full screen or a portion thereof. If all of the channels can be displayed in the given display area, another determination is made to determine the size of each of channel display areas (i.e., thumbnail). Having made this determination, visual representations of each channel in the user'"'"'s customized list is displayed. While the multi-channel display is being presented, the user can select one of them for customized editing.

d) providing visual representations of each of the plurality of channels in accordance with the channel display size such that the visual representations of each of the plurality of channels may be displayed on a single display.

2. The method of claim 1 further comprises, within steps (b) and (c), utilizing at least one of aspect ratio and minimum resolvable image size as the displaying characteristics.

3. The method of claim 2 further comprises determining the minimum resolvable image size to be one of:

a predetermined value, 80×

60 pixels, a user defined value, an automated value, and an interactive size value.

4. The method of claim 2 further comprising, within step (a), retrieving a plurality of television broadcast channels as the plurality of channels, wherein the plurality of television broadcast channels may be received by a tuner as at least one of:

RF broadcast television, cable broadcast television, satellite broadcast television, and a multi-cast mode broadcast.

5. The method of claim 4 further comprises the steps of:

detecting preview selection of one of the plurality of channels; and

providing at least one of live audio and live video of the one of the plurality of channels within a corresponding channel display.

6. The method of claim 5 further comprises providing the at least one of the live audio and the live video for a predetermined duration, a user defined duration, or until a termination signal is received.

7. The method of claim 6 further comprises, when the predetermined duration or the user defined duration ends or the termination signal is received, returning to updating the visual representations of the plurality of channels.

8. The method of claim 6 further comprises, prior to the predetermined duration or the user defined duration ending or receiving the termination signal, selecting the one of the plurality of channels for full display area viewing.

9. The method of claim 1 further comprises:

detecting an editing selection of one of the plurality of channels;

providing a set of optional viewing parameters;

detecting selection of a parameter of the set of optional viewing parameters; and

performing the parameter upon the visual representation of the one of the plurality of channels.

10. The method of claim 9 further comprises selecting one of:

an add/delete from a channel list, delete the one of the plurality of channels from the plurality of channels, add/delete to a lock-out list, or labeling the one of the plurality of channels as the parameter.

11. The method of claim 1 further comprises, within step (a), retrieving a plurality of radio broadcasts, which include graphical identifiers, as the plurality of channels.

12. The method of claim 1 further comprises, within step (b), determining the display area to be one of:

full screen or a window.

13. The method of claim 1 further comprises, within step (a), establishing the plurality of channels by one of:

automatic scanning of receivable channels and receiving channel selections from a user.

14. The method of claim 1 further comprises, when the plurality of channels cannot be displayed within the display area, displaying the visual representations of a subset of the plurality of channels using smallest channel display size that fulfills the displaying characteristics;

and providing a scrolling mechanism to view the visual representations of remaining channels of the plurality of channels.

15. The method of claim 1 further comprises refreshing the visual representations of the plurality of channels with more current data at a periodic rate.

16. A multiple channel display comprising:

a channel tuner;

a decoder operably coupled to receive broadcast signals from the channel tuner and to convert the broadcast signals into decoded representations;

a video graphics processing circuit operably coupled to the decoder, wherein the video graphics processing circuit generates pixel information from the decoder representations;

a digital storage medium that stores programming instructions that, when read by a processor within the video graphics processing circuit, cause the processor to prepare the pixel information for multiple channel display, the digital storage medium includes;

first means for storing programming instructions that, when read by the processor, causes the processor to retrieve identity of a plurality of channels;

second means for storing programming instructions that, when read by the processor, causes the processor to determine whether the plurality of channels can be displayed within a display area based on size of the display area, number of channels in the plurality of channels, and displaying characteristics;

third means for storing programming instructions that, when read by the processor, causes the processor to determine channel display size for each of the plurality of channels based on the displaying characteristics, the size of the display area, and the number of channels, when the plurality of channels can be displayed within the display area; and

fourth means for storing programming instructions that, when read by the processor, causes the processor to provide the pixel information for visual representations of each of the plurality of channels in accordance with the channel display size such that the visual representations of each of the plurality of channels may be displayed on a single display.

17. A digital storage medium that stores programming instructions that, when read by a processor, cause the processor to prepare the pixel information for multiple channel display, the digital storage medium includes:
