Problems solved by technology

[0004] Currently there is no effective solution for monitoring the quality of streaming media playback based on Transmission Control Protocol (TCP, Transmission Control Protocol). For example, for the most extensive Hypertext Transfer Protocol (HTTP, HyperText Transfer Protocol) streaming media based on TCP protocol, there are It is necessary to propose a QoE measurement method and indicators to measure the user's experience of streaming media quality

Abstract

The invention discloses a stream media transmission assessment method which is a method of obtaining initial play time delay information, calculating a subjective experience change value according to the initial play time delay information, and assessing stream media transmission quality. The method includes the steps of monitoring transmission control protocol (TCP) connection built with user terminals, obtaining the initial play time delay information if the TCP connection built with the user terminals is monitored to be stream media business connection, and calculating the subjective experience change value according to the initial play time delay information. The invention further provides a method, related equipment and a system of obtaining streaming media transmission quality assessment and information.

Description

technical field [0001] The present invention relates to the technical field of media transmission, in particular to a streaming media transmission quality evaluation and information acquisition method and related equipment and system. Background technique [0002] With the development of multimedia communication technology, various multimedia services emerge in an endless stream, so the quality of multimedia services plays a very important role in the fields of multimedia processing and multimedia communication. [0003] In previous performance tests of network equipment, people usually only focused on the forwarding performance of the equipment itself and the quality of service (QoS, Quality of Service) of the protocol (IP, Internet Protocol) interconnected between networks, such as throughput, packet loss rate and Latency and other indicators. In terms of implementation, network devices generally apply different priority policies to traffic of different service types to e...
