A decoding system (10) receives a composite digital NTSC D2 input signal or a composite analog NTSC RS-170A input signal. The decoding system (10) decodes and sample rate converts to a component digital D1 output and a component analog RGB or Y(R-Y) (B-Y) output. A control panel (20) is connected to the decoding system (10) to provide digital control of the important decoding parameters to provide decoding flexibility. The composite video signal is supplied directly to an adaptive combiner (44), through a line comb filter (48) to the adaptive combiner (44), and through a frame comb filter (52) to the adaptive combiner (44). The composite video signal is also supplied to a frame transition or motion detector (58) and to a line transition or motion detector (60). If no frame transition or motion is detected, the adaptive combiner (44) utilizes frame based three dimensional decoding. When frame transition or motion is detected, the adaptive combiner (44) drops back to two dimensional line combing for the decoding.

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.
