International ClassG11B 027/02Foreign Application Priority Data1989-04-27 JPAbstractVideo program information is edited from plural prerecorded source media onto an edited record medium. Each source medium includes video program information of a common scene which may be recorded at a location on the medium relative to a beginning location thereof that differs from the location relative to the beginning location on another source medium on which the same common scene is recorded. Each source medium includes address data representing discrete positions thereon and when the program information of the common scene is played back concurrently from the plural source media, the address data associated with the respective media also are played back. The played program information is monitored, and when a scene location in the common scene is played back substantially simultaneously from plural source media, the address data from each source medium representing the actual position at which the scene location is recorded on that source medium is stored as synchronized address data. Edit points on individual ones of the source media are selected; and the selected edit points are referenced to the synchronized address data. Hence, and as an example, although the starting point of a common scene may differ from medium to medium, the respective edit points on each medium relative to the starting point of that scene are in phase with each other. Playback of selected segments of video program information from repective source media for recording onto the edited record medium is controlled in accordance with the referenced edit points.Other References
