Claim 1

A variable-speed reproducing method for DVCR comprising the steps of: (1) converting a transported signal into a transport stream signal; (2) storing said converted transport stream signal as normal play data; (3) decoding said transport stream signal; (4) converting said transport stream signal into a video stream; (5) separating head information from said converted video stream; (6) detecting and storing only trick play data by using a start code separated from said head information; (7) recording the un-converted normal play data obtained in step 2 and the trick play data obtained in step 6 on tape; (8) selectively skipping the normal play data or the normal and trick play data depending on the rate of trick upon reception of a trick play signal after step 7; (9) detecting trick play data written on a trick region and converting said detected trick play data to said transport stream signal; and (10) transmitting the converted transport stream signal for playing the trick play data, wherein in eight-fold speed playback, 570 tracks where said normal play data and trick play data are recorded are skipped and 30 tracks where said trick play data is recorded are read and reproduced.
