摘要

Embodiments of the present invention provide a method, an apparatus, and a system for evaluating video quality. The method for evaluating video quality includes determining a lost packet in a video frame and a slice to which the lost packet belongs; determining, in the slice to which the lost packet belongs, a location of a most important lost packet in a current slice, where the most important lost packet is the lost packet having the largest influence on the video quality of the current slice; and determining the quality of the video frame according to the location of the most important lost packet in every slice. In the embodiments of the present invention, a method in the prior art that the video quality is determined only according to the number of lost packets and a packet loss rate is modified, and the location of the most important lost packet is determined by analyzing the influence of the lost packet on other packets, and a damage degree or degree of intactness of the video frame is determined according to the most important lost packets, so as to determine the quality of the video frame. The method greatly improves the precision for evaluating the video quality.
