An material information registration systemcompresses the musical numbers of the CDs for holding on a proprietary server and a proprietary serverof a multi-channel sending-out system. A large number of materials are held on the proprietary serverand read out from it. The read-out materials are converted in its format to a transmission format by a sending-out serverso as to be multiplexed by a multiplexer. The multiplexed data is QPSK-modulated by a modulatorand sent out via a selector. From the proprietary serverare read out data which is sent out via dedicated networkto a live PC where it is reproduced. This data is furnished again via dedicated networkand encoded by an MPEG encoderso as to be sent out at the sending-out server
