ABSTRACT:
A recording and reproducing system for a digital VTR for home use, to record video and aural signals onto the same track of tape, by adding stereo aural signals to digital video component signals, and to reproduce digital component signals and stereo aural signals recorded on the same track of the tape by way of separation. The system includes an aural signal adder adding respective stereo aural signals that were converted to digital signals through A/D converters onto data which are transmitted from image encoder under compression, and error correction encoders generating data transmitted from the aural signal encoders by adding error correction bits, and an aural signal separator separating stereo aural data from data generated from error correction decoder, and a D/A converter for converting aural signal separator signals into analog signals. Because the system records both image signal and aural signal onto the same track and processes them by using digital bits, it provides superior playback image quality as well as no deteriorations of either image or aural qualities upon playback.
