Certain aspects of the present disclosure are directed to a video processing module, including: a video capture module configured to capture a screen display; a compression module configured to compress the screen display to construct compressed data representing the screen display; and a memory module configured to store the compressed data. Certain aspects are directed to a computer-implementable method, including: reading compressed video data having a plurality of data units and representing a screen display out of a data storage, the data units including a line tag, an encoding tag, and a pixel value data unit; detecting a line tag from the compressed video data and extracting a line number from the line tag; receiving an expected line number from a counter; comparing the line number with the expected line number and determining a comparison result; and determining whether a fault exists based on the result. |
