Digital signal recording and reproduction

摘要

The television signal recording/reproducing system digitally records and reproduces television signals composed of a luminance signal, a chrominance signal and a resolution compensation signal included in predetermined television scanning lines. The system includes a Y/C separating circuit (108) for separating the luminance signal Y from the chrominance signal C and a decoder (114) for decoding the color signal into color difference signals CB, CR. One of the color difference signals CB, CR is combined (118) with the resolution compensation signal, and a digital video signal recorder (104) digitally records the combined resolution signal and the color difference signal. In this manner, the resolution compensation signal is accurately recorded.
