Title: Compressed video data recording method and recording apparatus providing improved performance during variable-speed playback

Abstract: A recording apparatus processes a stream of compressed video data to produce a recording signal which includes periodically occurring blocks of low-frequency video component data, for use in subsequent variable-speed playback operation. The processing is executed by selecting specific elements of low-frequency video components from the compressed video data, applying time-axis compression to the low-frequency video component elements to obtain successive data blocks, and to the compressed video data to obtain successive data blocks, between which the blocks of low-frequency video component elements are inserted.
