Abstract

PURPOSE:To ensure the assured selection and reception only for the desired one especially among a number of information in case the information which are different from each other are transmitted with every field and frame to be then received. CONSTITUTION:The video signal is amplified through amplifier 3, and the vertical synchronous signal is isolated from composite video signal 3' through vertical synchronous signal isolating circuit 4. Then rectangular wave signal 5' synchronizing with the front edge of the first equalization signal following the vertical synchronous signal is formed by FF5. Based on signal 5', the cue signal is formed. And for this purpose, time axis generator circuit 6, code formation circuit 7 and coding circuit 8 are provided each. The cue signal is piled on the composite video signal from amplifier 3 at mixer 9, thus signal 9' being obtained. The switch control is given to signal 9' via gate circuit 11, and the output 11' receives the FM modulation via modulator 12 to be then memorized in magentic medium 15 after more amplification.
