RECORDING DEVICE/METHOD FOR SPEED CHANGE REPRODUCTION OF VIDEO CASSETTE RECORDER FOR DIGITAL HDTV

摘要

PROBLEM TO BE SOLVED: To provide device/method for extracting speed change data from a digital HDTV signal and recording it in the specified region of a tape in digital VCR recording/reproducing the digital HDTV signal compressed with MPEGII as a reference. ;SOLUTION: The digital HDTV signal is separated into normal reproduction data and speed change reproduction data. Separated speed change reproduction data are stored in plural frame buffers 154A and 154B. Speed change reproduction data of a multi-frame is superimposed and recorded along a track so that tracking is started at an arbitrary position at the time of speed change reproduction and picture quality can be improved at low double speed. Speed change reproduction data is recorded in a safe track region so that speed reproduction data is safely detected even if a head non-linearly executes tracking.;COPYRIGHT: (C)1996,JPO
