Abstract

Disclosed are a method and device for monitoring the quality of a video stream. The method comprises: acquiring video stream information of a network side; determining a quality score of a reference frame and a coding quality score of a current video frame on the basis of the video stream information; determining a source coding quality score on the basis of the quality score of the reference frame, of the coding quality score of the current video frame, and of the coding type of the current video frame; determining a network loss score on the basis of the video stream information, where a network loss is a video stream quality loss caused by packet loss and delay jitter; and, determining a quality monitoring score of the video stream on the basis of the source coding quality score and of the network loss score. The present invention solves the problem in the relevant art of monitoring imprecision and complex implementation of a network side video stream quality monitoring method, accurately reflects dynamic changes in video quality, increases the accuracy in video stream quality monitoring, is of low complexity, and allows for convenient application in a 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...
