Abstract:
The invention relates to a method for transmitting a wireless video based on the multiple reference prediction chain coding, which includes: firstly, it initializes. Then, it source-encodes and channel-codes about multiple reference prediction chain coding according to the current volume of the reference prediction chains and synchronization points. Then, it sends it to the client-terminal through network transmission. Then, the client-terminal broadcasts the received video signals and feedbacks information to server via backing channel. Then, the server calculates the dropout rate and real-time updates the number of the reference prediction chains and synchronization points, after that, it encodes the video data, packs it, and sends it out.
