ABSTRACT:
A video signal processing apparatus, typically for use as a video tape recorder/reproducer for recording and reproducing high-definition television signals, includes an encoder for converting a chrominance signal into a line sequential signal, time-compressing the line sequential signal and multiplexing the time-compressed line sequential signal with a luminance signal according to time-division multiplexing, thereby producing a time-division-multiplexed signal. A vertical emphasis circuit is connected to an input terminal of the encoder, for performing vertical nonlinear emphasis on the chrominance signal. The video signal processing apparatus also includes a vertical low-pass filter for preventing aliasing distortions from the chrominance signal due to the conversion of the chrominance signal into the line sequential signal. The vertical nonlinear emphasis is performed on the chrominance signal after the chrominance signal has been processed by the vertical low-pass filter.
