ABSTRACT:
A recording apparatus for recording a compressed video signal on a disc has an adder for adding the sequence header at the beginning of the corresponding sequence, and also adding a copy of the sequence header at a beginning of the final GOP in the corresponding sequence. The reproducing apparatus for reproducing the compressed video signal from a disc has a control for controlling the pick-up device such that under the fast reverse play mode, the pick-up device jumps backward over a copied sequence header when the pick-up device enters a new sequence from a rear end thereof, and reads the copied sequence header. Thus, the compressed video signal in the sequence can be reproduced without reading the sequence header provided at the beginning of the sequence.
