Method and system for new layout experience in video communication

1. A method for composing a continuous presence videoconferencing layout for a videoconferencing session, the method comprising:

receiving a first video stream;

receiving a plurality of video streams;

selecting a subset of the plurality of video streams;

placing video from the first video stream into a main segment of the continuous presence videoconferencing layout;

placing video from each of the subset of the plurality of video streams into a respective strip video segment of a plurality of strip video segments of the continuous presence videoconferencing layout;

composing the plurality of strip video segments as a user-scrollable strip along an edge of the main segment; and

transferring the main segment and the plurality of strip video segments toward a display unit of a video device,

wherein each of the strip video segments plays one of subset of the plurality of video streams,

wherein a first portion of a strip video segment of the plurality of strip video segments is visible on the display unit of the video device, and

wherein a second portion of the strip video segment is invisible on the display unit of the video device.

2. The method of claim 1 ,

wherein the video device is a videoconferencing endpoint; and

wherein the first video stream is received from a first video conferencing endpoint of a videoconferencing session, and

wherein the plurality of video streams are received from a plurality of videoconferencing endpoints of the videoconferencing session.

3. The method of claim 2 , wherein receiving a first video stream comprises:

receiving the first video stream from a videoconferencing endpoint corresponding to a current speaker in a videoconferencing session.

4. The method of claim 1 , wherein the strip has a dimension greater than a corresponding dimension of the display unit.

5. The method of claim 1 , further comprising:

receiving a user command;

moving the first video stream from the main segment to a strip video segment of the plurality of strip video segments responsive to the user command; and

moving a second video stream from the strip video segment to the main segment, responsive to the user command.

6. The method of claim 5 , wherein the user command comprises:

pointing to the strip video segment; and

pulling the second video stream toward the main segment.

7. The method of claim 1 , further comprising:

receiving a user command; and

scrolling the plurality of strip video segments in the strip without affecting the main segment.

8. The method of claim 7 , wherein the user command comprises dragging a strip video segment in a direction.

9. The method of claim 8 ,

wherein the strip has a horizontal orientation, and

wherein the direction is left or right.

10. The method of claim 8 ,

wherein the strip has a vertical orientation, and

wherein the direction is up or down.

11. The method of claim 1 , further comprising:

generating a padding segment, having a dimension sized according to a corresponding dimension of the main segment and a corresponding dimension of the strip; and

forming a rectangular layout of segments from the main segment, the padding segment, and the strip.

12. The method of claim 1 , further comprising:

scaling the subset of the plurality of video streams according to a frame size of the plurality of strip video segments, and

scaling the first video stream according to a frame size of the main segment.

13. The method of claim 1 ,

wherein the strip video segments have a frame rate less than a frame rate of the main segment.

14. The method of claim 1 , varying the continuous presence videoconferencing layout dynamically responsive to changes in a videoconferencing session.

15. An apparatus, comprising:

a compressed video data interface; and

a plurality of video output modules, each associated with a display unit of a receiving video device and configured to:

obtain a first video stream;

obtain a plurality of video streams;

select a subset of the plurality of video streams;

place video from the first video stream into a main segment of a continuous presence videoconferencing layout;

place video from each of the subset of the plurality of video streams into a respective strip video segment of a plurality of strip video segments of the continuous presence videoconferencing layout;

compose the plurality of strip video segments as a user-scrollable strip along an edge of the main segment; and

transfer the main segment and the plurality of strip video segments toward the display unit via the compressed video data interface,

wherein each of the strip video segments plays one of the subset of the plurality of video streams, and

wherein only a portion of a strip video segment of the plurality of strip video segments is visible on the display unit.

16. The apparatus of claim 15 , wherein the first video stream corresponds to a current speaker in a videoconferencing session.

17. The apparatus of claim 15 , wherein each of the plurality of video output modules is further configured to:

swap video streams between the main segment and a strip video segment of the plurality of strip video segments responsive to a user command.

18. The apparatus of claim 15 , wherein each of the plurality of video output modules is further configured to:

scroll the plurality of video strip segments in the strip without affecting the main segment, responsive to receipt of a user scrolling command.

19. The apparatus of claim 15 , wherein the main segment has a frame rate greater than a frame rate of the strip video segments.

20. A method for composing a striped composed video image, wherein the striped composed video image has a main segment and a user-scrollable strip of a plurality of strip segments, the method comprising:

obtaining a decoded video image from a first video stream;

selecting two or more video streams of a plurality of video streams;

obtaining a plurality of decoded video images from the selected two or more video streams; and

composing a stream of striped composed video images by:

placing the decoded video image of the first video stream in the main segment; and

placing each of the plurality of decoded video images in a strip segment of the plurality of strip segments; and

transferring the stream of striped composed video images toward a display unit of a video terminal,

wherein composing the stream of striped composed video images is implemented according to a strip command originated by a user activity at the video terminal, while flowing video images in each of the plurality of strip segments,

wherein the user-scrollable strip is positioned along an edge of the main segment, and

wherein only a portion of a strip video segment of the plurality of strip segments is visible on the display unit.

21. The method of claim 20 , wherein the video terminal participates in a videoconferencing session.
