Abstract (en)

[origin: WO0074388A1] The disclosure relates to a method for transmitting a video bitstream corresponding to n multiplexed variable bitrate coded video bitstreams, when coded audio bitstreams are associated to said parallel video bitstreams. According to the proposed method, one or several audio parameters are defined from said audio bitstreams, and the bitrate allocations respectively associated to the parallel video bitstreams are each one weighted by a weighting parameter corresponding respectively to each of said audio parameter(s).
