Embodiment Construction
[0028] The basic idea of the present invention is to evaluate the quality of a video sequence by using the variation of the average difference between frames before and after coding the video sequence and the variation relationship of the maximum average bit number of a single frame before and after coding. At the encoding end, the peak signal-to-noise ratio (PSNR) method is used to calculate the inter-frame difference between each frame of the original video and the previous frame, and send the result to the receiving end; the receiving end directly extracts the encoded bits of the inter-frame encoding frame from the video stream Then use the PSNR method to calculate the inter-frame difference between the decoded inter-coded frame and its previous frame, and calculate the average value, and calculate the average value of the original inter-frame difference corresponding to the inter-coded frame. The inter-frame difference PSNR between an inter-coded frame and its previous fr...
