<p>A multichannel video compression system comprises a plurality of video encoders for encoding video signals along to a video coding rate, said video encoders receiving video signals from a channel, complexity determination means to determine the complexity of the encoded video signals, a multiplexer for multiplexing encoded video signals into a multiplexed encoded video signal, a controller to adapt the video coding rate of said video encoders with respect to an available bandwidth at the output of the multiplexer and the complexity of the encoded video signals of said video encoder. It further comprises associated forward error correction (FEC) coders for applying to said encoded video signals a forward error correction code at a channel coding rate, the controller having at least one additional input to receive a network transmission quality feedback of a video distribution network linked to the multichannel video compression system and additional outputs for controlling the channel coding rate of said forward error correction coders, the outputs of said forward error correction coders being provided to corresponding inputs of said multiplexer.</p> |
