Method and device for determining video transmission quality

Abstract

The invention discloses a method and device for determining video transmission quality. The method is applied to a video transmission network, and the video transmission network comprises a video server, network equipment and user equipment. The method comprises: collecting the data volume of a video stream by the network equipment in a predetermined period; acquiring a transmission duration formed by transmitting the data message to the user equipment in the predetermined period by the video server, and obtaining effective transmission duration obtained by removing the duration that the datatraffic is zero in a predetermined period, determining an average transmission rate according to the data volume of the transmission duration, determining an effective transmission rate according tothe effective transmission duration and the data volume, and determining the transmission quality of the video stream according to the average transmission rate and the effective transmission rate. According to the technical scheme provided by the invention, the transmission quality of the video stream can be determined without analyzing the data message content of the video stream, so that the transmission quality of the video encrypted and transmitted by protocols such as HTTPS and UDP can be evaluated, and the practicability is high.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for determining video transmission quality. Background technique [0002] With the development of Internet technology, video services are becoming an important part of Internet traffic. Online film and television works, online variety show content, user-made video content, and webcasting are accepted and loved by more and more people. With the improvement of transmission capability and the continuous improvement of video processing capabilities of video playback devices including mobile phones, tablet computers, and personal computers (personal computers, PCs), the quality of video content provided by video service providers to users is also continuously improved. [0003] Since the video streams transmitted in the network have the characteristics of large data traffic, strong continuity of data traffic, and sensitivity to network qualit...

Problems solved by technology

However, in order to improve the security of data transmission, more and more service providers are turning to use hypertext transfer protocol secure (HTTPS) or user datagram protocol (user datagram protocol, UDP) to transmit video streams. Both the HTTPS protocol and the UDP protocol transmit data in an encrypted manner, which makes it impossible to parse the content of the message header and obtain the bit rate of the video from the message header. Therefore, the above method cannot be applied to the video transmitted by the above encryption protocol, and has poor practicability
