ABSTRACT:
A video signal compression-encoding apparatus for receiving a plurality of successive video signals and subjecting the video signals to intra-frame encoding, forward predictive inter-frame encoding, and bidirectional predictive inter-frame encoding, thereby generating I-pictures, P-pictures, and B-pictures, respectively, is provided. The apparatus includes: an assigned data generator allowing a user to assign a picture to be subjected to the intra-picture encoding among the input pictures and generating assigned data representing the picture assigned by the user; and a group structure generator generating a group structure in such a manner that, in a case where the encoding is performed using a first group structure satisfying N=N1 and M=M1 (N1 and M1: natural numbers), when the picture assigned by the user is not identical with a second I-picture, a picture group having a second group structure different from the first group structure is positioned before the picture assigned by the user, wherein N is a period of each of the I-pictures, M is a period of each of the P-pictures, and the picture group includes a first I-picture among the I-pictures to a picture immediately before a second I-picture, which is the I-picture next to the first I-picture. A recording medium recorded by the apparatus and a video signal reproducing apparatus for reproducing the recording medium are also provided.
