Abstract

Apparatus for remultiplexing multi-program audio-video streams transmitted within a switched digital video broadcasting service. The apparatus comprises syntactical analysis and reception means for receiving plural streams, separating data packets in each stream that can be transported directly to means for generating output streams, from service packets that are transmitted to a control unit for processing, in particular for updating service information to reflect the composition of said output streams; means for temporary storage of data packets, separately for each input stream; and output stream generation means for generating and sending service users single program output streams or multi-program streams at a lower band than input streams obtained starting from the packets stored in the temporary storage means and from the service packets processed and entered into virtual ATM channels.
