RECORDING AND REPRODUCING DEVICE OF COLOR VIDEO SIGNAL

摘要

PURPOSE:To decrease greatly the number of component parts and at the same time to omit the control of a color video signal processing circuit, by using the A/D and D/A converters to digitize the color video signal processing circuit. CONSTITUTION:The color video signal supplied from an input terminal 1 is converted by an A/D converter 31 and then separated into the luminance and carrier chrominance signals by an LPF32 and a BPF33. The high band of the output of the LPF32 is emphasized by a pre-emphasis circuit 34. Then the output of the LPF32 is supplied to an adder 37 via an FM modulator 35 and an HPF36. While the output of the BPF33 is converted by a frequency converter 38 and then applied to the adder 37 via an LPF40. The output of the adder 37 is converted by a D/A converter 41 and recorded by a recording head 13. Thus the number of component parts can be greatly reduced since those filters, pre- emphasis circuit, frequency converter, etc. can be integrated. Furthermore this integration can omit the control of a color video processing circuit.
