To provide an interpolation data program transmitter by which interpolation data program information is acquired in a short time in matching a program of the main broadcast at a receiver side.
As to information data of an interpolation data program, the data are divided from the head by the amount to be superimposed on one video line sequentially and the divided data of the amount equipment to one line are fed to 1st to 4th insert sections A1-A4 of a digital inserter 1212, and the program data are transferred repetitively from the insert section A1 at a succeeding field again till the data are sent out and outputs from the insert sections A1-A4 are composited at a composite section B of a next-stage and the result is sent as one video signal. In a conventional teletext multiplex broadcast system, one program is sequentially superimposed on one line and a packet is transferred for each program, but in the configuration of the transmitter, since the program data are sent simultaneously in parallel, the data are sent at a speed faster by a multiple of a several number than that of the conventional system.
