In the process of digitalization, the standardization of digital signals is one of the most important links. From the point of view related to the interests of consumers, the more intuitive parameter is clarity. SMPTE (Motion Picture and Television Engineering Association of America) divides the scanning lines of digital high-definition signals into 1080P, 1080I and 720P(i stands for interlaced, and P stands for line by line, line by line).
