Abstract

A multimedia system may include at least one audio comment input device configured to permit at least one commentator to generate audio comment data based upon viewing video data from a video source. Furthermore, a media processor may cooperate with the at least one audio comment input device and be configured to process video source data and audio comment data and generate therefrom audio trigger markers synchronized with the video source data for predetermined audio triggers in the audio comment data, and combine the video source data, the audio comment data, and the audio trigger markers into a media data stream.

Claims

1. A multimedia system comprising:

at least one audio comment input device configured to permit at least one commentator to generate audio comment data based upon viewing video data from a video source; and

a media processor cooperating with said at least one audio comment input device and configured to

process video source data and audio comment data and generate therefrom audio trigger markers synchronized with the video source data for predetermined audio triggers in the audio comment data, and

combine the video source data, the audio comment data, and the audio trigger markers into a media data stream.

2. The multimedia system of claim 1 wherein the at least one audio comment input device comprises a plurality of audio comment input devices;

and wherein said media processor is further configured to generate the audio trigger markers based upon multiple occurrences of predetermined audio triggers within a set time.

3. The multimedia system of claim 2 wherein said media processor is further configured to generate the audio trigger markers based upon multiple occurrences of respective predetermined audio triggers from different audio comment input devices within the set time.

4. The multimedia system of claim 1 wherein said media server is further configured to store portions of the media data stream associated with occurrences of the audio trigger markers.

5. The multimedia system of claim 1 wherein said media processor combines the video data feed, the audio data feed, and the audio trigger markers by multiplexing to generate the media data stream.

6. The multimedia system of claim 1 wherein said media processor is further configured to generate notifications based upon occurrences of the predetermined audio triggers in the audio comment data.

7. The multimedia system of claim 1 further comprising a plurality of text comment input devices configured to permit a plurality of commentators to generate shared text comment data based upon viewing the video data;

and wherein said media processor is further configured to process the video source data and shared text comment data and generate therefrom a database comprising shared text comment data indexed in time with the video source data so that the database is searchable by text keywords to locate corresponding portions of the video source data.

8. The multimedia system of claim 1 wherein said media processor comprises a media server.

9. The multimedia system of claim 9 wherein said media server comprises a processor and a memory cooperating therewith.

10. A multimedia data processing method comprising:

generating audio comment data using at least one audio comment input device configured to permit at least one commentator to comment upon viewing video data from a video source;

processing video source data and audio comment data and generating therefrom audio trigger markers synchronized with the video source data for predetermined audio triggers in the audio comment data using a media processor; and

combining the video source data, the audio comment data, and the audio trigger markers into a media data stream using the media processor.

11. The method of claim 10 wherein the at least one audio comment input device comprises a plurality of audio comment input devices;

and further comprising generating the audio trigger markers based upon multiple occurrences of predetermined audio triggers within a set time using the media processor.

12. The method of claim 11 wherein generating comprises generating the audio trigger markers based upon multiple occurrences of respective predetermined audio triggers from different audio comment input devices within the set time.

13. The method of claim 10 further comprising storing portions of the media data stream associated with occurrences of the audio trigger markers using the media server.

14. The method of claim 10 wherein combining comprises multiplexing the video data feed, the audio data feed, and the audio trigger markers to generate the media data stream.

15. A physical computer-readable medium having computer-executable instructions for causing a media processor, coupled to at least one audio comment input device configured to permit at least one commentator to generate audio comment data based upon viewing video data from a video source, to perform steps comprising:

processing the video source data and audio comment data and generating therefrom audio trigger markers synchronized with the video source data for predetermined audio triggers in the audio comment data using a media processor; and

combining the video source data, the audio comment data, and the audio trigger markers into a media data stream.

16. The physical computer-readable medium of claim 15 wherein the at least one audio comment input device comprises a plurality of audio comment input devices;

and wherein generating the audio trigger markers comprises generating the audio trigger markers based upon multiple occurrences of predetermined audio triggers within a set time using the media processor.

17. The physical computer-readable medium of claim 16 wherein generating comprises generating the audio trigger markers based upon multiple occurrences of respective predetermined audio triggers from different audio comment input devices within the set time.

18. The physical computer-readable medium of claim 15 further comprising computer-executable instructions for causing the media sever to perform a step of storing portions of the media data stream associated with occurrences of the audio trigger markers using the media server.

19. The physical computer-readable medium of claim 15 wherein combining comprises multiplexing the video data feed, the audio data feed, and the audio trigger markers to generate the media data stream.
