Abstract: The picture quality is improved in video recorders through use of a band width compression by the operation-adaptive spectrum folding procedures associated with the recording and playback of colour video signals. The video input (10) leads to a Y/C separator (1) which separates the luminance and chrominance components of the composite signal. An operation-adaptive free filter (3) separates the luminance signal dependent upon the level of movement. A generator (6) produces spectrum folding carrier signals dependent on the output from the filter (3). Other circuits includes a low pass filter (5), a FM modulator (7), an adder (12), to provide output signal to the tape head, a low pass filter (9), and a processor (8) to combine the colour signal and tape modulation signal.

Abstract: Burst signal strength detector is designed to detect signal level and to vary tuning characteristics of IP amplifier by its level. This prohibits color quality deterioration by compensating attenuation in high frequency band and provides a way of minimizing receiving error of letter multiplex broad casting. System is composed of tuner (1), If amplification and detector (2), and burst signal amplitude detector (3) blocks. The tuner block is same as the one in TV set. IF amp. and detector consists of preamp (14), surface audio wave (SAW) filter (15), and VIP amp. and detector circuit (16). The burst signal detector (3) includes high pass band filter (18) filtering composite picture signal and burst signal amplitude detector circuit (17) capable of varying tuning characteristics of IP signal.
