Abstract

A system for providing interactive collaboration between a plurality of users. The system includes a profile respository for storing a priority level for each of said plurality of users and providing addresses for accessing each of said plurality of users. A media content server indexes audio and video data within the system. A data server stores the audio and video data at locations identified by indexing data located at the media content server. An acquisition processor provides audio and video data streams to requesting ones of the plurality of users. Audio and video data streams are located based on indexing data within the media content server and accessed according to a priority level for each requesting user. A communication processor controls bidirectional communication between requesting users according to the priority level for each requesting user.

Claims

1. A system for providing interactive collaboration between a plurality of users, said system comprising:

a profile respository for

16. The system of claim 10, wherein said annotations are superimposed in at least one of within a frame of video data, external to a frame of video data, a hotspot, and a selected area of interest on a video picture.

17. The system of claim 1, further comprising an interface processor for providing an interface for

combining and displaying said audio and video data streams acquired by said acquisition processor and said bidirectional communication controlled by said communication processor.

18. The system of claim 17, further comprising an annotation processor accessible by each requesting user for annotating said audio and video data streams provided by said acquisition processor.

19. The system of claim 18, wherein said interface processor combines and displays annotations made by said annotation processor with each of said acquired audio and video data and said bidirectional communication.
