VIDEO TRANSMISSION SYSTEM

摘要

A system (10) enables information associated with a video transmission to be selected and retrieved without limiting the bandwidth of the video transmission system. For example, in the course of one video transmission, a user can tag (26) a given portion of the transmission. That tag may be adapted to enable identification of related information that may be transmitted asynchronously on another video transmission channel. The information may be retrieved from a different channel (29) and the user may be notified when the information has been received (45), so that the user can view the information at his or her leisure.
