ABSTRACT:
The present invention has as its object to reduce the time and and effort in the work of finding a portion necessary for editing work from a video signal recorded on a video tape. A VTR apparatus (12) reproduces a video signal and sampling data showing the start and end of the shot from a video tape (120). A VP circuit (22) reduces the size of the video signal. A detection circuit (24) detects the boundaries of scenes or important portions based on the reproduced sampling data. The sampling memory (30) samples and records the video signal reduced by the VP circuit (22) at a timing of detection of the boundaries of the scene or important portions by the detection apparatus (24). A display device (34) displays the video signal stored in the sampling memory (30) in a predetermined array along with a time code etc.
