Abstract:
An editing system comprising:a video signal reproducing device for reproducing video signals for a first plurality of scenes from a storage medium, comprising a plurality of individual disc media, and outputting said video signals for said first plurality of scenes consecutively through a first output port out of a plurality of output ports, said video signal reproducing device further reproducing video signals for a second plurality of scenes from said storage medium and outputting said video signals for said second plurality of scenes consecutively through a second output port out of said plurality of output ports;a first field/frame memory for storing either a field or a frame represented by the video signals coming from said first output port;a second field/frame memory for storing either a field or a frame represented by the video signals coming from said second output port;a first special effect processor having two input terminals, one of the two input terminals being supplied with the video signals corresponding to a second one of said first plurality of scenes from said first output port, the other input terminal being fed with output video signals corresponding to said first one of said first plurality of scenes from said first field/frame memory, said first special effect processor providing any one of a plurality of special effects outputting at least a portion of said second one of said first plurality of scenes and said first one of said first plurality of scenes simultaneously;a second special effect processor having two input terminals, one of the two input terminals being supplied with the video signals corresponding to a second one of said second plurality of scenes from said second output port, the other input terminal being fed with output video signals corresponding to said first one of said second plurality of scenes from said second field/frame memory, said second special effects processor providing any one of a plurality of special effects outputting at least a portion of said second one of said second plurality of scenes and said first one of said second plurality of scenes;a first controller for controlling the writing and reading operations of data to and from said first field/frame memory as well as the retaining operation of data in said first field/frame memory; anda second controller for controlling the writing and reading operations of data to and from said second field/frame memory as well as the retaining operation of data in said second field/frame memory;wherein said first and said second controllers perform the control operations thereof in such a manner that said first and said second field/frame memories continuously supply said first and said second special effect processors each with the video signals representing either the last field or the last frame of said first one of said first or second plurality of scenes, respectively, for a predetermined period said first and second special effects processors thus each simultaneously providing output video, each including special effects.
