<p>Disclosed in the present invention are a method, a device and a system for transmitting and processing multi-channel AV (audio-video). The method comprises the following steps: obtaining respectively multi-channel AV code streams; in a merging processing step, merging each channel AV code stream into at least one channel composite code stream, wherein each channel AV code stream merged in the composite code stream is correspondingly provided with a code stream identification used for identifying the AV code stream belonged to; and transmitting the composite code stream to an AV receiving terminal based on a network transport protocol for indicating the AV receiving terminal to divide the composite code stream into each channel AV code stream according to the code stream identification. In the present invention, the multi-channel AV code streams are integrated into at least one channel composite code stream so as to reduce the number of the AV code streams; thus when the code stream is transmitted by the network, the network channel is no need to be occupied independently, and the phenomenon that some channels are busy and some channels are free will not occur, thereby taking fully advantage of network resource and raising transmitting efficiency.</p> |
