Patent ID: 8726332

Claim:
A broadcast programming delivery apparatus, comprising: a broadcast programming delivery control unit that controls broadcast programming delivery based on a broadcast programming delivery program formed of a plurality of items; and a switcher for video signals, the switcher being controlled by the broadcast programming delivery control unit, a material server having a plurality of output channels for outputting video material being connected to predetermined input lines of the switcher, wherein the items of the broadcast programming delivery program include control data of the switcher having information for specifying a video material of the material server, the broadcast programming delivery control unit receives, from the material server, channel material information indicating respective video material outputted from each of the output channels of the material server, and checks, in conducting control of the switcher according to each of the items of the broadcast programming delivery program, control data of the switcher included in the item against the channel material information to obtain a correspondence of each of a plurality of video materials, and allows an input bus of the switcher necessary to take an input of a video material of the material server to select one of the input lines corresponding to the output channel of the material server from which the corresponding video material is outputted, and the switcher includes key source cross-points formed of switches connected to key source signal select input buses that supply video material inputted to one of the predetermined input lines as a key source signal, key fill cross-points formed of switches connected to key fill signal select input buses that supply video material inputted to another one of the predetermined input lines as a key fill signal, and background cross-points formed of switches connected to background signal select input buses that supply video material inputted to a further one of the predetermined input lines as background signals.
