Method, apparatus, and system for evaluating video quality |
摘要 |
Embodiments of the present invention provide a method, an apparatus, and a system for evaluating video quality. 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. |

1. A method for evaluating video quality, comprising:
estimating a location of each slice of multiple slices in a video frame, by dividing a total number of packets of the video frame to the multiple slices, and determining a location of ending packet in each of the multiple slices according to a number of packets of every slice, wherein the number of packets of every slice is equal; determining a lost packet in the video frame and a slice to which the lost packet belongs; determining a location of a most important lost packet in the slice to which the lost packet belongs, wherein the most important lost packet is a lost packet having the largest influence on a video quality of a current slice; and determining a video quality of the video frame according to the location of the most important lost packet in every slice. |
