    • 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.
    • 一种视频信号记录和再现装置,包括视频信号记录块和视频信号再现块。 视频信号记录块包括用于从视频信号检测子信息和/或特征量的子信息/特征量检测器,用于根据子信息产生对应于视频信号的各个帧的识别信号的识别信号发生器 和/或特征量,以及记录器,用于将记录信号与视频信号一起记录在记录介质上的程序区域的扇区中。 识别信号被记录在包含视频信号的相应帧的节目区域的每个扇区中的子码区域中。 视频信号再现块包括用于检测来自子代码区域的识别信号的识别信号检测器和用于产生由对应于检测到的识别信号的程序区域的扇区中记录的视频信号的各个帧组成的屏幕的再现装置。
