Abstract
A serial digital video data analyzer combines a co-processor capable of handling the serial digital video data stream bit rate with a microprocessor operating at a slower bit rate. The co-processor includes a video feature detection/decision module that identifies specified errors or features from the serial digital video data stream and freezes the portion of the serial digital video data stream around such feature/error in a video data store. The co-processor may also insert a cursor into the serial digital video data stream prior to display on a monitor to indicate the position of indicated errors. The acquired serial digital video data is transferred to the microprocessor for an initial determination as to whether further processing is required. If further processing is required, the results are displayed as a report and the microprocessor interacts with the co-processor to acquire additional data needed for processing or to indicate that the processing is completed and the co-processor should continue its feature detection/decision process. In this way any desired analysis of the serial digital video data stream may be performed.
