ABSTRACT:
A video signal editing apparatus has a simplified configuration and still can edit a number of video signals in an efficient way. The video signal editing apparatus performs an editing operation by using video signal combined to display a plurality of moving scenes on a single screen of a video display. The apparatus includes a first signal path 40 transmitting all video signals, a signal extracting device for extracting a desired video signal out of the transmitted video signals for a scene selected from the displayed moving scenes, a second path having a pair of image memories for storing the extracted video signal, a storage device for storing editing data concerning the timing, the mode and the duration of time of switching moving scenes, a CUE signal and other editing data in synchronism with the time base of the video signals and a data controller for reproducing and transferring editing data. The data representing the extracted video signal stored in the image memory is read out at the same time when a video signal which is to be displayed after the extracted video signal in the same field in which the extracted video signal is displayed, is read out of the image memory.
