Abstract:
1. A method for assessing the quality of a video signal during encoding or compressing of the video signal, the method comprising the steps of: estimating, by a video quality processor, the quality (Qcod) of the encoded or compressed video signal using one or more parameters; using, by the video quality processor, at least one additional parameter to adjust the estimated video signal quality, wherein the at least one additional parameter includes the key-frame rate (kfr) of the video signal as a Group of Pictures (GOP)-length-related parameter; and outputting, by the video quality processor, the adjusted estimated video signal quality; wherein the adjustment of the estimated video signal quality is in accordance with the following equation: where a1, a2, b, and c are coefficients and br is the bit-rate of the video signal.
