ABSTRACT:
To raise the integration level of a video recorder, and to provide a uniform circuit concept suitable for all three color-television standard (PAL, NTSC, SECAM) which, in particular, requires only slight modifications for adaptation to the respective standard, signal processing is performed by fast digital circuits whose signals are stored on the recording medium not in digital form, but after digital-to-analog conversion. The composite color signal is converted into digital form by a fast analog-to-digital converter (aw) whose sampling signal (fc) has a fixed frequency (Fc) for all three color-television standards. Digital signal processing in the chroma channel is performed at a fixed subcarrier frequency (zt) for all three color-television standards which is an integral subharmonic of the sampling frequency (Fc).
