Wide Band Video Signal Recorder Having Level and Linearity Corrector

Extensive works are now being carried out on the development of band compression techniques for the transmission of the high definition TV (HD-TV), which would be practiced in future by utiIizing one of the channels of 12 GHz band satellite broadcastings. In this, the bandwidth of HD-TV signal which occupies the bandwidth several times that of the present system, is compressed to less than 9 MHz. By making use of the above techniques. it is desired to provide a new video signal recorder with the capability of 9 M Hz band recordings.
