Abstract

A method for managing distribution of video includes receiving a plurality of video data streams from a plurality of video data source devices associated with a group. Each video data stream includes a plurality of video frames and a plurality of metadata fields. The video data streams is parsed to extract the video frames and information comprising the plurality of metadata fields. A common group metadata stream is generated which includes metadata information from the plurality of metadata fields. The common group metadata stream is communicated to user equipment devices (UEDs) operated by users who may have an interest in video streams. Upon receipt of a demand for a first user video stream based on information contained in the common group metadata stream, a first user video stream is generated and communicates to a UED.

Claims

1. A method for managing distribution of video media in a group setting, comprising:

receiving at a group server a plurality of video data streams respectively generated in a plurality of video data source devices associated with a group, each said video data stream including a plurality of video frames and a plurality of metadata fields;

operating a computer processor at said group server to parse said video data streams for extracting said video frames and information comprising said plurality of metadata fields;

generating a common group metadata stream which selectively includes metadata information from each of said plurality of metadata fields;

communicating said common group metadata stream to a plurality of user equipment devices (UEDs) comprising said group;

receiving from at least one of said UEDs, a demand for a first user video stream based on said common group metadata stream;

in response to said demand, generating a first user video stream comprising said plurality of video frames included in one of said video data streams, and communicating said first user video stream to said UED from which said demand was received.

2. The method according to claim 1, further comprising generating said demand at one or more of said plurality of UEDs based on an evaluation at said UED of said group metadata stream to determine if video frames associated with one or more of said video data sources is of interest to a user.

3. The method according to claim 2, wherein said evaluating includes generating secondary metadata comprising information not directly specified by said metadata contained in said video data streams.

4. The method according to claim 2, further comprising determining based on said group metadata stream whether it is desirable to supplement said first user video stream with at least a second user video stream.

5. The method according to claim 4, further comprising identifying based on said group metadata stream, one or more second user video streams relevant to said first user video stream.

6. The method according to claim 5, wherein metadata associated with said second user video stream is not included in said group metadata stream.

7. The method according to claim 6, further comprising generating a second group metadata stream including metadata associated with said second user video stream, and communicating said second group metadata to selected ones of said UEDs in said first group.

8. The method according to claim 1, further comprising using said computer processor at said server to evaluate said plurality of metadata fields contained in each of said plurality of video data streams to determine if said plurality of video frames associated with at least one of said video data sources should be automatically communicated to one of said UEDs.

9. The method according to claim 1, further comprising generating secondary metadata comprising information not directly specified by said metadata generated at said plurality of video data source devices.

10. The method according to claim 9, further comprising communicating said secondary metadata to said UEDs in said common group metadata stream.

11. A method for managing distribution of video media in a group setting, comprising:

receiving at a group server a plurality of video data streams respectively generated in a plurality of video data source devices associated with a group, each said video data stream including a plurality of video frames and a plurality of metadata fields;

operating a computer processor at said group server to parse said video data streams for extracting said video frames and information comprising said plurality of metadata fields;

generating a common group metadata stream which selectively includes metadata information from each of said plurality of metadata fields;

communicating said common group metadata stream to a plurality of user equipment devices (UEDs) comprising said group;

receiving from at least one of said UEDs, a conditional demand for a first user video stream based on said common group metadata stream;

in response to said demand, generating a first user video stream comprising said plurality of video frames included in one of said video data streams, and communicating said first user video stream to said UED from which said demand was received.

12. The method according to claim 11, wherein said conditional demand specifies at least one processing action to be performed by said computer processor prior to said communicating said first user video stream to said UED

13. The method according to claim 12, wherein said at least one processing action comprises an analysis of a video content of at least a portion of a scene represented by at least one of said video data streams.

14. The method according to claim 13, wherein said analysis comprises identifying an occurrence of movement in said portion of said scene.

15. The method according to claim 13, wherein said portion is specified in said conditional demand.

16. The method according to claim 12, wherein said at least one processing action comprises an enhancement or modification of a video content of said first user video stream.

17. The method according to claim 11, further comprising generating said demand at one or more of said plurality of UEDs based on an evaluation at said UED of said group metadata stream to determine if video frames associated with one or more of said video data sources is of interest to a user.

18. The method according to claim 17, wherein said evaluating includes generating secondary metadata comprising information not directly specified by said metadata contained in said video data streams.

19. The method according to claim 17, further comprising determining based on said group metadata stream whether it is desirable to supplement said first user video stream with at least a second user video stream.

20. A system for managing distribution of video media in a group setting, comprising:

a group server configured to receive a plurality of video data streams respectively generated in a plurality of video data source devices associated with a group, each said video data stream including a plurality of video frames and a plurality of metadata fields;

at least one computer processor at said group server configured to;

parse said video data streams and extract said video frames and information comprising said plurality of metadata fields;

generate a common group metadata stream which selectively includes metadata information from each of said plurality of metadata fields;

communicate said common group metadata stream to a plurality of user equipment devices (UEDs) comprising said group;

receive from at least one of said UEDs, a demand for a first user video stream based on said common group metadata stream; and

in response to said demand, generate a first user video stream comprising said plurality of video frames included in one of said video data streams, and communicating said first user video stream to said UED from which said demand was received.
