Abstract

The invention discloses a video display quality calculating method and an equipment, belongs to the multimedia technology field and can solve a problem that a video quality calculating method in the prior art can not accurately present the video display quality. The method comprises steps that screen display quality of a video, a frame rate of the video and a code rate of the video are acquired, the video display quality is calculated through a first preset algorithm according to the screen display quality, the frame rate and the code rate, and the video display quality is used for indicating the highest display quality value of the video on a display screen. The method is used for calculating the video display quality.

Description

technical field [0001] The invention relates to the field of multimedia technologies, in particular to a method and device for calculating video display quality. Background technique [0002] With the rapid development of multimedia technology, video data has become the main data of network transmission, and video display quality has also become a key indicator to measure network service quality. Therefore, how to conveniently and effectively determine the video display quality has become an urgent problem to be solved. [0003] In the prior art, in one implementation mode, the video quality is obtained by calculating according to the video frame type, video frame size, frame rate and code rate; in another implementation mode, the peak signal-to-noise ratio (PSNR) of the video data is calculated. : Peak Signal to Noise Ratio, referred to as: PSNR), to determine the video quality. [0004] In the process of realizing the above calculation of video quality, the inventor foun...
