Abstract

An approach is provided for synchronizing video frames. Video proxies corresponding to a video master are generated. Each of the video proxies is frame-accurate with respect to the video master. The video proxies are distributed to multiple applications and/or devices that are configured to collaboratively use the video proxies. The approach also allows the user to move a session from one device to another device, while preserving frame accuracy.

First claim

What is claimed is:

1. A computer-implemented method performed by one or more processors following coded instructions, the one or more processors causing:
receiving a token that designates a controller of a collaborative session, wherein the collaborative session utilizes a plurality of video proxies corresponding to a video master; and
transmitting, to a frame synchronizer, frame information associated with the video proxy corresponding to the controller,
wherein the frame synchronizer is configured to update the other video proxies based on the received frame information.

2. The method according to claim 1 , wherein each of the video proxies is generated according to a format that is compatible with respective applications configured to display the video proxies.

3. The method according to claim 2 , wherein the applications reside respectively on a plurality of communication devices that include a mobile phone, a laptop computer, a desktop computer, a personal digital assistant (PDA), or a combination thereof.

4. The method according to claim 1 , further comprising:
retrieving the video proxy from a central repository.

5. The method according to claim 1 , wherein the video master is output from a live feed.

6. The method according to claim 1 , further comprising:
displaying a graphical user interface (GUI), wherein the GUI includes,
a section for the video proxy associated with the controller,
an instant communication box for conducting an instant communication session with one or more users of the other video proxies,
a metadata section for specifying metadata about the video proxy associated with the controller,
a first text box for displaying text of the controller, and
a second text box for displaying text of one or more users of the other video proxies.

7. An apparatus comprising:
memory;
at least one processor for receiving a token that designates a controller of a collaborative session, wherein the collaborative session utilizes a plurality of video proxies corresponding to a video master; and
a communication interface configured to transmit, to a frame synchronizer, frame information associated with the video proxy corresponding to the controller,
wherein the frame synchronizer updates the other video proxies based on the received frame information.

8. The apparatus according to claim 7 , wherein each of the video proxies is generated according to a format that is compatible with respective applications for displaying the video proxies.

9. The apparatus according to claim 8 , wherein the applications reside respectively on a plurality of communication devices that include a mobile phone, a laptop computer, a desktop computer, a personal digital assistant (PDA), or a combination thereof.

10. The apparatus according to claim 7 , wherein the at least one processor causes a retrieval of the video proxy from a central repository.

11. The apparatus according to claim 7 , wherein the video master is output from a live feed.

12. The apparatus according to claim 7 , further comprising:
a display for displaying a graphical user interface (GUI), wherein the GUI includes,
a section for the video proxy associated with the controller,
an instant communication box for conducting an instant communication session with one or more users of the other video proxies,
a metadata section for specifying metadata about the video proxy associated with the controller,
a first text box for displaying text of the controller, and
a second text box for displaying text of one or more users of the other video proxies.
