Problems solved by technology

[0003] At present, in the multi-channel video transmission scenario of the video surveillance business, when the video streams generated by multiple surveillance cameras are transmitted concurrently on the same network, the traffic peaks of the multiple video streams often overlap, that is, intra-frame encoded images Frame (Intra-coded picture, I frame) collision phenomenon, causing network congestion, packet loss, etc., making the planned network bandwidth insufficient, resulting in video freeze and other problems, affecting the operation of video surveillance services

Abstract

The invention provides a video transmission test method, device and system and a terminal, and the method can comprise the steps that a first terminal obtains N paths of video streams, and N is a positive integer greater than 1; the first terminal controls the N paths of video streams to be concurrently transmitted to the second terminal through the first network, the first terminal controls I frames in M paths of video streams in the N paths of video streams to collide when the N paths of video streams are transmitted, and M is larger than or equal to 2 and smaller than or equal to N; the second terminal receives the video frames of the N paths of video streams and determines a first index of each path of video stream in the N paths of videos, and the first index is used for representing the video transmission capability of the first network. Therefore, when a network where multi-channel video transmission is located is tested, I frames in a part of or all video streams can be controlled to collide, so that a scene in which the I frames collide randomly during concurrent transmission of the multi-channel video streams after a monitoring service is online is simulated, various practical application scenes can be covered in a test process, and the test efficiency is improved. And thus, the video transmission capability of the pre-configured network is effectively tested.

Description

technical field [0001] The present application relates to the technical field of network testing, and in particular, to a video transmission testing method, device, system and terminal. Background technique [0002] With the rapid development of mobile communication technology, the 5th generation mobile network (5G network) is gradually applied to people's daily life and work, which promotes the development of digital economy and society and the digital transformation and upgrading of traditional industries, especially It has had a huge impact on the transformation of traditional industries. Among them, the video surveillance service of Internet Protocol Camera (IPC) is one of the representatives of 5G industry applications. [0003] At present, in the multi-channel video transmission scenario of the video surveillance service, when the video streams generated by the multi-channel surveillance cameras are transmitted concurrently in the same network, the phenomenon of super...
