Abstract

The invention discloses a video stream quality monitoring method and device. The method includes: obtaining video stream information of a network side; according to the video stream information, calculating a quality score of a reference frame and a coding quality score of a current video frame; according to the quality score of the reference frame, the coding quality score of the current video frame and the coding type of the current video frame, calculating a source coding quality score; according to the video stream information, calculating a network damage score, the network damage being video stream quality damage caused by packet loss and delay jitter; and according to the source coding quality score and the network damage score, determining a quality monitoring score of a video stream. Through video stream quality monitoring method in the invention, the problems in related technology that a network side video stream quality monitoring method is not high in monitoring precision and implementation is relatively complicated are solved, dynamic changes of video quality is accurately reflected, accuracy of video stream quality monitoring is improved, complexity is not high, and the video stream quality monitoring method can be conveniently applied to network side video quality real-time monitoring environment.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a video stream quality monitoring method and device. Background technique [0002] In recent years, with the increase of network bandwidth, real-time video services such as streaming media services, video telephony services, and video conference services have developed very rapidly. Accurate evaluation of the quality of these video services can not only let users understand the service level of video services, but also provide service providers with a yardstick for service level improvement, which plays an important role in the good operation of services. Especially in the actual operation of the business, the online monitoring of the business can dynamically grasp the quality status of the business operation, and timely discover the quality problems in the process of business operation, which has strong practical value. [0003] The online monitoring of video streaming servi...
