Abstract
Abstract A receiver for receiving a still picture broadcasting signal consisting of a composite signal comprising a video signal representing a plurality of still pictures, an audio signal in the form of a pulse code modulated and time division multiplexed signal representing a plurality of sounds, a control signal including information for processing said video and audio signals at a receiver end and a synchronizing signal necessary for reproducing said video, audio and control signals at the receiver end, said signals being arranged in a predetermined sequence at a period of a predetermined time interval, said receiver extracting said control signal and desired still pictures and sounds being accurately extracted and displayed with the aid of the extracted control signal. Said control signal comprises a program material identification signal consisting of a video identification number for identifying a video signal of each still picture and of an audio channel number identifying an audio signal inserted in each audio channel, a first control signal for selecting a particular combination from a number of combinations of said still pictures and sounds and controlling progress of reproduction in accordance with a predetermined rule and a second control signal for denoting a combination of a still picture and a sound inserted in a channel, which combination constitutes a set of program material.
