A method and device for determining video transmission quality

Abstract

A method and device for determining video transmission quality. Wherein, the method is applied to a video transmission network, and the video transmission network includes a video server, network equipment and user equipment. The method includes: the network device collects the data volume of the video stream in a predetermined period, obtains the transmission duration formed by the video server transmitting the data message to the user equipment within the predetermined period, and obtains the time length obtained by removing the time period in which the data flow is zero in the predetermined period The effective transmission time, and determine the average transmission rate according to the data volume of the transmission duration, and determine the effective transmission rate according to the effective transmission time and data volume, and determine the transmission quality of the video stream through the average transmission rate and the effective transmission rate. The technical solution provided by this application can determine the transmission quality of the video stream without analyzing the content of the data message of the video stream, so as to evaluate the transmission quality of the video encrypted and transmitted using protocols such as HTTPS and UDP, and has strong practicability .

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
