摘要： An RM unit for remultiplexing multi-program audio-video streams transmitted within an switched digital video broadcasting service includes: as, FL1 . . . FLn, MS1 . . . MSn syntactical analysis and reception means receiving plural streams, separating data packets in each stream that can be transported directly to CF, AA, MA, TU means for generating output streams, from service packets that must be transmitted to an MP control unit for processing, in particular for updating service information to reflect the composition of output streams; ME means for temporary storage of data packets, separately for each input stream; and CF; AA, MC, TU output stream generation means that generate and send service users single program output streams or multi-program streams at a lower band than input streams obtained starting from the packets stored in such ME temporary storage means and from the service packets processed and entered into virtual ATM channels.
