ABSTRACT:
A pair of field store devices which are slaved to a stable sync signal are employed to record, along with such sync signal, video information on a recording medium. During periods of asynchronism in the video input to the field store devices, synchronous noise or a synchronous blank is inserted into the output of the field store devices. Such use of field store devices enables (1) the easy conversion of one recording format to another; (2) the splicing of scenes recorded on different tapes of the same, or different formats to be effected on a tape with any format; and (3) the recording of stillframe scene information.
