A demultiplexer receives an MPEG1 system stream obtained by multiplexing encoded data of video and audio and separates the stream into elementary streams (ES) of video and audio. A packetizer forms packetized elementary streams (PES) of MPEG2. Finally, a multiplexer divides the stream into transport packets each having a prefixed length of 188 bytes and, after that, converts the stream to an MPEG2 transport stream (TS).

A multimedia communication system which allows a user at a terminal to efficiently place an order for merchandise with a merchandise provider includes terminals and a multimedia server connected thereto via a public network. The multimedia server includes an information storage unit for storing multimedia information on each merchandise item, a communication control unit for controlling information transmission between terminals and the server via the public network, and a bulletin board service unit for transmitting merchandise items from the information storage unit to the communication control unit in response to a merchandise information look-up request from any of terminals. The multimedia server further has an ordering service unit and a main service unit. The ordering service unit enters the quantities and delivery times of merchandise ordered from a terminal into a received order master file, transcribes what is input in the master file onto a slip, and enters the slip into a received order file after adding to the slip the address, name and user code number of the user who placed the order. The mail service unit transmits slips held in the ordering service unit to the terminal of a merchandise delivery center via the communication control unit.
