Abstract: In a preferred embodiment, when full-motion video data is to be captured on a hard disk, a full-motion video memory on a video controller card has its addresses segmented into four groups, where each group can store one scaled-down frame (or field) of video data. The video memory is arranged to effectively act as a four-frame, first-in first-out (FIFO) buffer. The holding time of a single frame of data (i.e., four times the conventional holding time) in the video memory is sufficient to allow for the unpredictable variations in the hard drive timing so that frames are not arbitrarily dropped by worst case timing/accessing times of the hard drive. Hence, the average bandwidth and timing of the hard drive, rather than the instantaneous worst case bandwidth and timing of the hard drive, is used when designing the system.
