DIRECTION IDENTIFIER FOR RECORDING OF TRICK PLAY SIGNALS ON A RECORD CARRIER

摘要

A format for the recording of trick play signals in which trick play segments including sync blocks of information of a trick play signal are recorded in the tracks. At least first and second trick play signals are recorded on the record carrier. The first trick play signal is meant for reproduction in a reproduction apparatus at a reproduction speed n1 times the recording speed with which the trick play signals are recorded on the record carrier. The second trick play signal is meant for reproduction in the reproduction apparatus at a reproduction speed -n1 times the recording speed. Both trick play signals are recorded in the tracks such that, upon reproduction at the speed n1 times the recording speed, m1 sync blocks of information of the first trick play signal and, upon reproduction at the speed -n1 times the recording speed, m1 sync blocks of the second trick play signal are read from the record carrier during one revolution of the head drum in the reproduction apparatus. Further, a direction identifier is stored in the trick play sync blocks, indicating whether a trick play sync block is meant for a specific trick play speed in the forward or in the reverse direction.
