ABSTRACT:
The method allows performing the multiplexing of audio-visual streams, coded according to standard MPEG1, to be sent to remote equipment where demultiplexing and decoding occur. The method takes into account the trend of the occupancy of the input buffers of the remote decoders in order to avoid possible underflow or overflow conditions. For this purpose a multiplexed stream is constructed, composed of packets of variable sizes, by choosing the streams on the basis of the urgency to receive data that the demultiplexing buffers BDi have in order not to become empty.
