[0111] Specifically, the test audio and video segments used in this application are synthesized by the audio and video playback terminal 21 according to a specific audio and video synthesis method. The out-of-sync duration of the audio and video clips to be tested transmitted by the audio and video interactive system to be tested. Wherein, the synthesis method of the test audio and video segment of the present application is as follows: Figure 5 As shown, step S401 specifically includes the following steps:

[0112] Step S4011, generate unique corresponding video frame frame numbers for multiple audios with different frequency values ​​stored in advance.

[0113] Wherein, the audios are all monophonic audios, and the frequencies of the monophonic audios are all different and greatly different, so that it is easy to distinguish. For example, the frequency of audio S1 is 100 Hz, the frequency of audio S2 is 200 Hz, and the frequency of audio SN is (N-1)100 Hz. In practice, m...

Abstract

The invention provides an audio and video interaction system audio and video out-of-step test method, device and system, and relates to the field of real-time audio and video communication technology and finance. The method comprises the following steps: configuring network states of a sending terminal and a receiving terminal of a to-be-tested audio and video interaction system according to preset network configuration parameters; sending a test start instruction to an audio and video playing terminal arranged at the sending terminal, so that the audio and video playing terminal synthesizes and plays a test audio and video clip; receiving the out-of-step duration of a test audio and video clip transmitted by the audio and video interaction system to be tested and sent by an audio and video acquisition terminal arranged at the receiving terminal; and generating a sound and picture out-of-step report according to the out-of-step duration and the current network state. By synchronizing the network state of the conference terminal, the special test audio and video clip is synthesized, accurate measurement of audio and video out-of-step of the audio and video interaction system is realized, and a developer is enabled to find defects of the conference system.

Description

technical field [0001] The invention relates to real-time audio and video communication technology and the financial field, in particular to a method, device and system for testing audio and video out of synchronization in an audio and video interactive system. Background technique [0002] With the migration of banking business to online, real-time audio and video communication technology is more and more used in the business processing of bank credit and risk control. Studies have shown that in the process of real-time audio and video communication, when the audio and video are out of sync and the out-of-sync time exceeds 80 milliseconds, the communication participants will feel out of sync. When the out-of-sync time exceeds 120 milliseconds, the communication participants will feel obvious discomfort. Therefore, it is very necessary to test the out-of-synchronization of audio and video in the real-time audio and video interactive system. [0003] At the same time, since...
