    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 for separating the luminance signal Y from the chrominance signal C and a decoder for decoding the color signal into color difference signals C.sub.B, C.sub.R. One of the color difference signals C.sub.B, C.sub.R is combined with the resolution compensation signal, and a digital video signal recorder digitally records the combined resolution signal and the color difference signal. In this manner, the resolution compensation signal is accurately recorded.

    摘要： A digital VTR is provided with a block segmenting circuit for converting an input digital picture signal into data segmented into blocks of picture elements, an encoding circuit for compressing and encoding the output data of the block segmenting circuit block-by-block, a channel encoding circuit for channel encoding the encoded output data from the encoding circuit, an audio signal encoding circuit for encoding an input digital audio signal, and an additional code generating circuit for generating an additional control code which includes subdata. The encoded picture data from the channel encoding circuit, the encoded audio data output from the audio signal encoding circuit, the additional control code and pilot signal data for tracking are recorded in skewed tracks traced on a magnetic tape by a magnetic head or heads mounted on a rotary drum, with each skewed track having pilot signal data recorded at least adjacent the end portion of the track at which the magnetic head enters into contract with such track, subdata recorded at the other end portion at which the magnetic head leaves the track, and the picture data and the audio data recorded at an intermediate portion of the track, so that both picture data and audio data can be reproduced with high quality while the subdata can be played back with relatively high accuracy.

    摘要： Recording and reproducing a television signal with a DC shifter prevents compression distortion of a PAL plus television signal. The PAL plus television signal includes a vertical resolution signal for enhancing vertical resolution which vertical resolution signal is included in the same compression blocks as some of the component video signals. Such compression blocks are shifted to a DC set up value so that the signals within those compression blocks do not have varying DC offsets which otherwise could result in compression distortion. Similarly, upon reproduction, the DC set up value is removed after decompression and the original television signal is restored with complete vertical resolution.
