Abstract
In a system for transmitting multimedia data including video data, audio data, graphic data, text data and the like via a network, sets of media data are stored in a plurality of servers in a distributed state. When requested multimedia data is assigned from a transmitter, necessary sets of data from among media data stored in the servers in a distributed state are acquired by corresponding receivers in accordance with the assignment. A synchronization control unit and a multiplexer multiplex the acquired media data based on time stamps of the data, and transmit multimedia data after the multiplexing to a client which has assigned the multimedia data. According to such a configuration, distributed multimedia servers can be constructed without taking into consideration of influence by the effective rates of transmission channels from the respective servers.
