Abstract

The embodiment of the invention provides a video data transmission method and a corresponding video data transmission device. The method and the device can be applied to the articulated naturality web. The articulated naturality web comprises an articulated naturality web server and an articulated naturality web terminal, the XMCU server is controlled by extending multiple points; The articulatednaturality web server is in communication connection with the articulated naturality web terminal and the XMCU server. The articulated naturality web terminal splits each collected video frame into aplurality of video data packets with packet serial numbers, receives reply confirmation information returned by the XMCU server for the video data packet when each video data packet is sent, if the reply confirmation information comprises the packet serial number of the video data packet, continues to send the next video data packet, and If the reply confirmation information does not comprise thepacket serial number of the video data packet, sends the video data packet to the XMCU server again, so it can be ensured that all video data are sent to the XMCU server, and video data packet loss isavoided.

Description

technical field [0001] The present application relates to the technical field of video networking, in particular to a method and device for video data transmission. Background technique [0002] With the development of the Internet of Vision technology, each terminal transmits audio and video in the Internet of Vision more and more frequently. In this way, with the increase of terminals, the network traffic between the core servers of the Internet of Vision will continue to increase. Due to the impact of network bandwidth, jitter, and processing pressure on each server, the core server of the Internet of View will produce out-of-order or packet loss when translating audio and video streams, resulting in low-quality video images and poor user experience. Contents of the invention [0003] In view of the above problems, the embodiments of the present application are proposed to provide a video data transmission method and a corresponding video data transmission device that o...
