摘要

A video signal recording and reproduction apparatus comprising a video signal recording block and a video signal reproduction block. The video signal recording block includes a sub information/feature amount detector for detecting sub information and/or a feature amount from a video signal, an identification signal generator for generating identification signals corresponding to respective frames of the video signal in accordance with the sub information and/or feature amount, and a recorder for recording the identification signals together with the video signal in sectors of a program area on a recording medium. The identification signals are recorded in a sub code area in each sector of the program area containing the corresponding frames of the video signal. The video signal reproduction block includes an identification signal detector for detecting the identification signals from the sub code areas and reproduction means for generating a screen comprised of respective frames of the video signal recorded in the sector of the program area corresponding to the detected identification signals.
