Abstract
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.
