description PROBLEM TO BE SOLVED: To provide a multiplexer that transfers an MPEG multi-program transfer stream to an ATM virtual channel and multiplexes the virtual channel on a virtual path. SOLUTION: A syntax analysis section AS receives a plurality of streams and separates data packets in each stream from service packets. The data packet is directly transferred to a means to generate an output stream, that is, an output stream generator CF and also sent to a processing/controller MP. The processing/controller MP conducts processing and especially updates service information and returns a synthesized output stream. The output stream generator CF generates a single program output stream or a multi-program stream at a frequency band lower than that of the input stream and sends it to a service user. The output stream is obtained by beginning from the packet stored in a temporal storage means that is a memory device ME and the service packet that is processed and set to the virtual ATM channel.
