A media stream transmission apparatus for transmitting a plurality of media streams comprises a packet assembler for coupling a plurality of information units for transmitting the respective media streams into a single packet, and a multicast packet transmitter for multicasting the packet. A media stream reception apparatus is connected to the media stream transmission apparatus through a network having a multicast-capable router, and comprises a multicast packet receiver for receiving a multicast packet, an information element extractor for extracting one or plural information elements to be reproduced from the received packet, and a reproduction unit for reproducing the extracted information element or elements.
