Cassette managing data is read or written with a cassette accommodated in its bin. Cassettes 2a, 2b, 2c, and so on are attached at particular positions thereof to IC cards 1a, 1b, 1c, and so on respectively. Cassette bins 4a, 4b, 4c, and so on have read/write devices 3a, 3b, 3c and so on respectively at positions communicable with the IC cards. Control information of each cassette is read with the cassette accommodated in its bin from the read/write device and the read control information is controlled by a control server 5 via a LAN 9a. A robotics unit 8 is controlled by the control server 5 via a LAN 9c to move cassettes to the bins 4a, 4b, 4c, and so on or an image and/or sound information input/output block 7.

Data transmission system capable of routing and transmitting digital

A system for distributing broadcasting material a source station transmits a material signal representing a series of broadcasting material segments, together with a segment data signal containing segment data, such as the absolute start frame number of each segment and the number of frames in each segment. Each of a number of branch stations receives the transmitted material segments and the segment data signal, records the broadcasting material segments, and then files away the broadcasting material segments, for example in a cart machine, in accordance with the received segment data. The transmission may be by way of an artificial satellite, and it is unnecessary for the transmission from the satellite to the branch stations to be synchronised with the transmission from the source station to the satellite.
