Abstract
A variable-speed reproducing method for DVCR comprising the steps of: (1) converting a transported signal into a transport stream (TS) signal; (2) storing the converted TS signal as normal play data; (3) detecting trick play data from the converted TS signal; (4) separately recording the trick play data and normal play data formed in the steps 2 and 3; and (5 and 6) if a trick play signal is input, reading and reproducing only the recorded trick play data at a corresponding speed, thereby facilitating trick play by DVCR.
