Video data recording apparatus for digital video cassette recorder

Abstract

A video data recording apparatus for a digital VCR comprising a frame controller for detecting a vertical synchronous signal from input video data and outputting a frame detect signal and a first switching signal in response to the detected vertical synchronous signal, a switching counter for generating a second switching signal in response to the frame detect signal from the frame controller to control a switching operation of a track distributed switch, a buffer for dividing the input video data distributed by the track distribution switch in the unit of segment and storing the video data of the divided segments, a segment shifting counter for generating a third switching signal in response to the first switching signal from the frame controller, a shifting switching circuit for selectively transferring the video data from the buffer in response to the third switching signal from the segment shifting counter, a signal select switching circuit for selectively transferring the video data from the shifting switching circuit in response to the first switching signal from the frame controller, and a recording circuit for adding a synchronous signal and an identification signal to output video data from the signal select switching circuit and recording the resultant video data on the video tape.
