Method for distributing digital TV signal and selection of content |
摘要 |
The present invention is a process in which broadcasters can supplement existing multimedia streams such as video and audio with additional multimedia streams in a coordinated and integrated way, allowing users, after reception of the broadcast stream, to select which sub-stream to use, without requiring an upstream channel to communicate this user preference back to the server or any additional bandwidth to broadcast these additional streams.
