    • 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.
    • 本公开的某些方面涉及视频处理模块,包括:视频捕捉模块,被配置为捕获屏幕显示; 压缩模块,被配置为压缩所述屏幕显示以构成表示所述屏幕显示的压缩数据; 以及被配置为存储压缩数据的存储器模块。 某些方面涉及一种计算机可实现的方法,包括:读取具有多个数据单元的压缩视频数据,并从数据存储器中显示出屏幕显示,数据单元包括线标签,编码标签和像素值 数据单元 从压缩视频数据中检测线标记并从线标识中提取行号; 从计数器接收预期的行号; 将行数与预期行数进行比较并确定比较结果; 并根据结果确定是否存在故障。
