Abstract
An apparatus for intermittently recording or reproducing a time-varying image includes a buffer interposed between a compression-encoder unit and a recording processor or between a decoder and a reproducing processor, a buffer controller for monitoring the quantity of effective information stored in the buffer, and a system controller for interrupting and restarting the operation of the recording processor or the reproducing processor according to the quantity of the effective information stored in the buffer. During recording, a plurality of consecutive image frames is separated into a plurality of groups, in each of which the image frames are intraframe or interframe compression-coded to digital image information. The total quantity of compression-coded digital image information is limited to a value smaller than a first predetermined value. The digital image information contained in each group is partitioned in units of a second predetermined value smaller than the first predetermined value. The recording or reproduction is carried out for each unit of information at a rate at which the maximum quantity of the digital image information in one group can be processed on real-time basis.
