Abstract
Method and apparatus for detecting and correcting error in an uncompressed digital video image data stream. The method and apparatus identify error or partial picture scenarios. Each of the possible error or partial picture scenarios is identified in a Partial Picture Repair Unit, which causes error processing of the uncompressed video input stream, resulting in the creation of a repaired data stream on the repaired pixel bus. The repair begins upon detection of an erroneous picture, field, or line. Processing for that picture, field or line is stopped upon detection of an error in the synchronization signals, and processing is resumed when the end of line, end of field, or end of picture indicator is detected.
