Problems solved by technology

[0008] In the existing technical solutions for video quality assessment, the subjective quality assessment method requires an experimental environment, and invests a lot of manpower and material resources as a comparison reference. Usually, it can only be evaluated for a specific video and test environment. Today, when video services are popular, Virtually impossible to assess video quality for all environmental locations and endpoints
The full-reference quality assessment method requires professional testing equipment and more video transmission network bandwidth to provide information about the original reference video, which is usually only applied in professional testing

Abstract

The invention discloses a video quality evaluating method and device. The method includes acquiring wireless channel measurement data and application layer transmission performance statistics data during a video data transmission process; determining the difference between the wireless channel measurement data and a first evaluation reference and the difference between the application layer transmission performance statistics data and a second evaluation reference; evaluating video quality of the video data according to the determined difference. The invention can provide a technical solution, which is simple in algorithm and easy to implement, for objective video quality evaluation.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a video quality evaluation method and device. Background technique [0002] With the maturity of LTE (Long Term Evolution, Long Term Evolution) network technology, network multimedia applications related to video have developed rapidly. Video suffers from data loss during compression, transmission and storage, introducing various distortion effects. In order to obtain a better subjective video effect, it is necessary to evaluate the quality of the distorted video, and adjust the relevant parameters of the encoder and transmission channel according to the evaluation results. [0003] In most current network multimedia systems, video quality assessment has become an indispensable and important part, which is mainly divided into Subjective Quality Assessment (SQA) and Objective Quality Assessment (OQA). According to the degree of dependence on the original video, qu...
