Abstract

A digital audio/video recorder which combines the digital audio processor (which conforms to the requirements of the EIAJ Technical File) with the VHS-format color video cassette recorder (VCR) has been developed on a commercial basis. The analog processor in the recorder contains IC-fashioned 14-bit analog-to-digital (A/D) and digital-to-analog (D/A) converters and a sample & hold (S/H) circuit, through which a distortion of less than 0.01% and dynamic range of better than 84 dB have been achieved. The digital processor in the recorder contains five newly developed CMOS LSI's of which signal processing system complies with the NTSC and PAL/SECAM television standards. Those LSI's are functionally equivalent to approximately 500 general purpose TTL integrated circuits, and provide increased data protection quality.
