Abstract
A real-time disk system (10) stores and plays back D1 digital 10-bit 4:2:2 component video and audio signals from magnetic storage disks (12). The system (10) has a main channel subsystem (14) with an associated smooth motion option (16) and a second or key channel option subsystem (18) with an associated smooth motion option (20). Serial and parallel D1 digital video inputs (30) and (32) and outputs (34) and (36) are connected to each of the channels (14) and (18) and to control subsystem (22). In the main channel (14), the serial and parallel D1 input (30) is connected through an input board (60) to a video processing board (62). The video board (62) is connected by a bidirectional, 11.times.2 wide bus (64) to disk arrays (66) and (68). Digital video signal information is stored and retrieved in parallel to and from the disk arrays (66) and (68) without requiring any serial to parallel or parallel to serial conversion. Smooth motion option (20) processes a group of video fields by creating a plurality of additional fields between two original fields in the group of video fields by a combination of motion adaptive interpolation and frame repetition.
