Abstract
Provision is made of a video signal editing apparatus wherein even if coded video signals subjected to inter-frame coding are connected and edited, no disturbance occurs in the video signal obtained as a result. Therefore, when connecting coded video signals in each of which one B-frame and I-frame constitute a GOP in that order, if the B-frame comes at the end of a coded video signal, the signal is divided adding to it up to the I-frame of the same or subsequent GOP. Further, if the B-frame comes at the start of a coded video signal, the signal is divided adding to it up to the B-frame or I-frame of the same or previous GOP, then these coded video signals are connected.
