System for distributing broadcasting material and identifying segment data
First Claim
1. A system for distributing broadcasting material, comprising:
- a source station comprising transmitting means for transmitting a composite signal having a series of broadcasting material segments preceded by a segment data signal, said segment data signal containing segment data representing the position and length of each of said broadcasting material segments in the series; and
a plurality of branch stations, each said branch station comprising receiving means for receiving the transmitted composite signal with the supplied segment data signal, recording means for recording the broadcasting material segments on a recording medium, and filing means for filing each of the broadcasting material segments recorded by the recording means on said recording medium at a location specified by the segment data contained in the segment data signal, said broadcasting material segments to be rebroadcast simultaneously by said plurality of branch stations.

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.

16. A branch station for a broadcasting material distribution system having a central source station and a plurality of branch stations, each said branch station comprising:
-
receiving means for receiving a composite signal having a series of broadcasting material segments preceded by a segment data signal, said segment data signal containing segment data specifying the position of each of said broadcasting material segments in said series and a length of each of said broadcasting material segments in said series; recording means for recording the received broadcasting material segments on a recording medium; and filing means for separately filing each of the broadcasting material segments recorded by the recording means on said recording medium at a location specified by the segment data contained in the segment data signal, said broadcasting material segments to be rebroadcast simultaneously by said plurality of branch stations. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A central source station for use in a broadcasting material distribution system having a plurality of rebroadcasting branch stations, said central source station comprising transmitting means for transmitting a composite signal, having a series of broadcasting material segments and a segment data signal inserted into a vertical blanking period of said broadcasting material segments, to said plurality of rebroadcasting branch stations, said segment data signal containing segment data for identifying each broadcasting material segment in the series and a length of each broadcasting material segment in the series;
wherein said segment data signal also comprises data which identifies locations in a recording medium at said rebroadcasting branch stations, said rebroadcasting branch stations having means for recording said broadcasting material segments at said locations in said recording medium.

29. A branch station for a broadcasting material distribution system having a central source station and a plurality of branch stations, each said branch station comprising:
-
a receiver for receiving a composite signal having a segment data signal and a plurality of broadcasting material segments, said segment data signal specifying a position of each broadcasting material segment and a length of each broadcasting material segment and said broadcasting material segments being comprised of video signals and audio signals; a decoder for receiving said composite signal and for separating said segment data signal from said broadcasting material segments; a controller for receiving said segment data signal from said decoder; and a recorder for recording said broadcasting material segments on a recording medium at locations specified by said controller in accordance with said segment data signal; wherein said branch station rebroadcasts said broadcasting material segments simultaneously with other branch stations.
