Embodiment 1

[0053] Please refer to figure 1 , figure 1 It is a flowchart of a video reconstruction quality testing method in an embodiment of the present invention, the method includes the following steps:

[0054] S101. Use a network simulator connected to a video sending end and a video receiving end to simulate a target network loss.

[0055]In this embodiment, a network simulator may be pre-connected between the video sending end and the video receiving end. The video sending end and the video receiving end are relative to the transmission direction of a certain video, and the video sending end of A video can also be the video receiving end of B video at the same time. The video sending end and the video receiving end in this embodiment can be regarded as regular terminals participating in the video conference, wherein the division of the video sending end and the video receiving end is mainly to determine which terminal's video data is used as a reference when evaluating the video ...

Abstract

The invention discloses a video reconstruction quality test method, device and equipment, and a readable storage medium. The method comprises the following steps: simulating target network loss by using a network simulator connected with a video sending end and a video receiving end; obtaining and counting data packets received by the video receiving end, and obtaining time delay data; obtaining avideo coding code stream of the video sending end and a video decoding code stream of the video receiving end; performing quality evaluation on the reconstructed video by using the time delay data, the video coding code stream and the video decoding code stream to obtain video reconstruction quality data; and establishing a corresponding relation graph of the target network loss and the video reconstruction quality data so as to optimize the quality of the reconstructed video by utilizing the corresponding relation graph. According to the method, the specific influence condition of the targetnetwork loss on the video reconstruction quality can be determined, the reconstructed video instruction can be further optimized based on the influence condition, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a video reconstruction quality testing method, device, equipment and readable storage medium. Background technique [0002] At present, a typical video conferencing system is composed of a terminal device, a communication network, a multipoint control unit (MCU), and the like. The audio and video quality presented by the video conference terminal that the video conference user experiences determines the quality of the user experience. [0003] It can be seen that improving the quality of reconstructed audio and video is particularly critical to improving user experience. According to the video quality evaluation system of the existing video conferencing system, the links that affect the audio and video quality of video conferencing can be divided into three categories: quality factors in video source processing such as acquisition and encoding, quality factors in n...
