Abstract

When a viewer initiates channel surfing, a surfing guide is presented to the viewer. The surfing guide provides multiple channel regions, where each channel region is associated with a different channel that is available to the viewer. Each channel region will include a channel window in which an image or video content from the corresponding channel is displayed. When the surfing guide is being displayed to the viewer, the channel window in at least one of the channel regions will include video content, which is derived from a low bandwidth video stream for the associated channel. Each channel region may also have a channel information area in which textual information about the corresponding channel is provided to the viewer.

6. The customer premise equipment of claim 1 wherein initial generation and display of the surfing guide is provided in response to receiving a surfing input from the user, and the first low bandwidth video stream is being received prior to receiving the surfing input.

7. The customer premise equipment of claim 1 wherein the control system is further adapted to determine to generate the surfing guide in response to receiving a surfing input from the user and request the first low bandwidth video stream after receiving the surfing input from the user, wherein the first low bandwidth video stream is not provided until being requested by the control system.

8. The customer premise equipment of claim 1 wherein the control system is further adapted to:

receive a surfing input after effecting display of a first instance of the surfing guide wherein the plurality of channel regions in the surfing guide for the first instance are allocated to a first group of channels;

update the surfing guide for a second instance based on the surfing input;

effect display of the second instance of the surfing guide wherein the plurality of channel regions in the surfing guide for the second instance are allocated to a second group of channels, which is different from the first group of channels.

9. The customer premise equipment of claim 8 wherein the first group of channels and the second group of channels include at least one common channel.

10. The customer premise equipment of claim 9 wherein a difference in channels between the first group of channels and the second group of channels represents scrolling through at least a portion of a list of channels to be surfed.

11. The customer premise equipment of claim 10 wherein the list of channels to be surfed is a numerical list of available channels.

12. The customer premise equipment of claim 10 wherein the list of channels to be surfed is a list of favorite channels.

13. The customer premise equipment of claim 1 wherein the control system is further adapted to, prior to effecting display of the surfing guide:

receive a second high bandwidth video stream comprising second video content for a second channel via the communication interface; and

effect display of the second video content for the second channel from the second high bandwidth video stream; and

receive a surfing input from the user wherein generation and effecting display of the surfing guide is provided in response to the surfing input.

14. The customer premise equipment of claim 13 wherein the surfing guide is displayed with the second video content for the second channel from the second high bandwidth video stream provided in a second channel window of the plurality of channel windows for a second channel region of the plurality of channel regions

15. The customer premise equipment of claim 13 wherein the control system is further adapted to receive a second low bandwidth video stream comprising the second video content for the second channel via the communication interface, wherein the surfing guide is displayed with the second video content for the second channel from the second low bandwidth video stream provided in a second channel window of the plurality of channel windows for a second channel region of the plurality of channel regions.

16. The customer premise equipment of claim 1 wherein the control system is further adapted to:

receive a surfing input from the user when the first channel is deemed active; and

update the surfing guide to indicate that a channel other than the first channel is active in response to the surfing input.

17. The customer premise equipment of claim 1 wherein a plurality of low bandwidth streams for at least a majority of available channels are received all of the time.

18.
