Abstract

A method and structure is capable of scanning through available programs on a display screen and selectively displaying the most recently scanned programs in a spiral formation on the display screen. The spiral formation conveys visual information to the viewer about when the programs were scanned by the arrangement and sizing of a number of positions of the spiral formation. Provided with the visual information of the recently scanned programs in the spiral formation, the viewer can readily determine which programs were recently scanned and when they were scanned.

Claims

1. A method for displaying available programming on a display screen of a video system that provides visual information to a viewer of the video system, the method comprising:

determining channels that the viewer selects for viewing to provide a sequence including

a first channel, a second channel, and a third channel, wherein relative to each other the first channel is the least recently viewed channel and the third channel is the most recently viewed channel;

receiving a signal that invokes a display mode in which depictions of programming content on previously viewed channels are simultaneously presented on the display screen; and

responsive to receipt of the signal that invokes the display mode, simultaneously displaying on the display screen depictions of programming content on a plurality of previously viewed channels including the first, second and third channels, wherein the plurality of previously viewed channels are displayed in a spiral formation, a first location of the spiral formation corresponding to the most recently viewed channel, with more recently viewed channels among the plurality of previously viewed channels appearing closer to the viewer and occupying more display screen surface area relative to less recently viewed channels, such that the depiction of the third channel occupies more display screen surface area than the depiction of the second channel, and the depiction of the second channel occupies more display screen surface area than the depiction of the first channel.

2. The method of claim 1, wherein the depiction of the programming content on the most recently viewed channel includes the current video and audio signals corresponding to the most recently viewed channel.

3. The method of claim 1, wherein a first end of the spiral formation is the first location, and further comprising:

receiving a signal that selects a fourth channel;

updating the display screen in the display mode to depict the fourth channel at the first end of the spiral formation, and rotating the depictions of the first, second, and third channels along the spiral towards a second end of the spiral formation.

4. The method of claim 3, wherein the depiction of the fourth channel comprises current audio and video signals for the fourth channel, and the depictions of the first, second and third channels comprise still images.

5. The method of claim 4, wherein in the display mode additional programming information corresponding to the programming content available on the fourth channel is simultaneously displayed in proximity with the depiction of fourth channel.

6. A storage media containing a computer program for displaying available programming on a display screen of a video system that provides visual information to a viewer of the video system, the computer program including instructions for:

determining channels that the viewer selects for viewing to provide a sequence including a first channel, a second channel, and a third channel, wherein relative to each other the first channel is the least recently viewed channel and the third channel is the most recently viewed channel;

receiving a signal that invokes a display mode in which depictions of programming content on previously viewed channels are simultaneously presented on the display screen; and

responding to receipt of the signal that invokes the display mode by simultaneously displaying on the display screen depictions of programming content on a plurality of previously viewed channels including the first, second and third channels, wherein the plurality of previously viewed channels are displayed in a spiral formation, a first location of the spiral formation corresponding to the most recently viewed channel, with more recently viewed channels among the plurality of previously viewed channels appearing closer to the viewer and occupying more display screen surface area relative topless recently viewed channels, such that the depiction of the third channel occupies more display screen surface area than the depiction of the second channel, and the depiction of the second channel occupies more display screen surface area than the depiction of the first channel.

7. The storage media containing a computer program of claim 6, wherein the depiction of the programming content on the most recently viewed channel includes the current video and audio signals corresponding to the most recently viewed channel.

8. The storage media containing a computer program of claim 6, wherein a first end of the spiral formation is the first location, and the computer program further comprises instructions for:

receiving a signal that selects a fourth channel; and

updating the display screen in the display mode to depict the fourth channel at the first end of the spiral formation, and rotating the depictions of the first, second, and third channels along the spiral towards a second end of the spiral formation.

9. The storage media containing a computer program of claim 8, wherein the depiction of the fourth channel comprises current audio and video signals for the fourth channel, and the depictions of the first, second and third channels comprise still images.

10. The storage media containing a computer program of claim 9, wherein in the display mode additional programming information corresponding to the programming content available on the fourth channel is simultaneously displayed in proximity with the depiction of fourth channel.

11. An apparatus for displaying available programming on a display screen of a video system that provides visual information to a viewer of the video system, the apparatus comprising:

means for determining channels that the viewer selects for viewing to provide a sequence including a first channel, a second channel, and a third channel, wherein relative to each other the first channel is the least recently viewed channel and the third channel is the most recently viewed channel;

means for receiving a signal that invokes a display mode in which depictions of programming content on previously viewed channels are simultaneously presented on the display screen; and

means for responding to receipt of the signal that invokes the display mode by simultaneously displaying on the display screen depictions of programming content on a plurality of previously viewed channels including the first, second and third channels, wherein the plurality of previously viewed channels are displayed in a spiral formation, a first location of the spiral formation corresponding to the most recently viewed channel, with more recently viewed channels among the plurality of previously viewed channels appearing closer to the viewer and occupying more display screen surface area relative to less recently viewed channels, such that the depiction of the third chanrel occupies more display screen surface area than the depiction of the second channel, and the depiction of the second channel occupies more display screen surface area than the depiction of the first channel.

12. The apparatus of claim 11, wherein the depiction of the programming content on the most recently viewed channel includes the current video and audio signals corresponding to the most recently viewed channel.

13. The apparatus of claim 11, wherein a first end of the spiral formation is the first location, further comprising:

means for receiving a signal that selects a fourth channel; and

means for updating the display screen in the display mode to depict the fourth channel at the first end of the spiral formation, and rotating the depictions of the first, second, and third channels along the spiral towards a second end of the spiral formation.

14. The apparatus of claim 13, wherein the depiction of the fourth channel comprises current audio and video signals for the fourth channel, and the depictions of the first, second and third channels comprise still images.

15. The apparatus of claim 14, wherein in the display mode additional programming information corresponding to the programming content available on the fourth channel is simultaneously displayed in proximity with the depiction of fourth channel.
