Title: Color video signal recorder
Inventor: ISHIKAWA TAKASHI
IPC: H04N9/82
Filed: 1986-12-24
Abstract: PURPOSE:To record a color video signal of wide bands with high density by recording a first signal inverted synchronously with the rise of an FM modulated wave and a second signal inverted synchronously with the fall of the FM modu lated wave on the same recording medium. CONSTITUTION:A composite NTSC color television signal is FM-modulated so as to have a modulated frequency twice as long as convensional frequencies by an FM modulator 14 and the signal inverted synchronously with the rise of the FM modulated wave and the signal inverted synchronously with the fall are formed by 1/2 frequency dividers 16a, 16b and these signals go to the video signals of two channels. The sum signal of the L channel and the R channel of a stereophonic audio signal is superimposed on the one channel of the video signals and a difference signal and a time base correcting reference signal in a reproducing system are respectively superimposed on the other. The recording signals of two channels obtained in this manner are simultaneous ly recorded on the recordding medium. Thereby, the color video signal of the wide band can be recorded with high density.
