A system for real-time capture and playback of high resolution compressed and uncompressed digital video data received upon a JPEG video board (10) over an input line (D1). This input is converted into YUV, and may be scaled and adjusted for color, contrast, hue and saturation. A bus interface (16) is in communication with the video input to provide a high resolution digital video data stream. A transient memory (20) communicates with the interface (16) over a first data path (11), and a digital storage medium (31, 35, 36, 40) communicates with the transient memory over a second data path (12), where the first and second data paths are configured to permit real-time storage of the data stream under microprocessor control.
