A video data transmission method and device

Abstract

The embodiment of the present invention provides a video data transmission method and device. The method is applied to the Internet of Vision, including: the Internet of Vision terminal searches for the target plan information according to the plan identification input by the user, including: the terminal identification of the target Internet of View terminal, The server identification of the target video network server, the split screen information of the target video network terminal, and the media receiving port number corresponding to the split screen information; the video network terminal sends the plan information to the target video network server according to the server identification; the target video network server sends the plan The information is forwarded to the streaming media platform; the streaming media platform determines the target video network terminal, and sends the corresponding video stream to the target video network terminal according to the media receiving port number. In the embodiment of the present invention, by sending the plan information, the split-screen information and receiving port number in the current video playback are confirmed, which avoids the playback delay caused by the need to confirm the video source, parameter information, etc. one by one for multiple channels of video in the split-screen playback question.

Description

technical field [0001] The invention relates to the technical field of video networking, in particular to a video data transmission method and device. Background technique [0002] The Internet of View is a real-time network that can realize real-time transmission of high-definition video across the network, and promote video services to high-definition video. At present, when video data is transmitted in the Internet of Vision, each channel of video involved needs to undergo multiple signaling interactions to confirm the path of video playback. [0003] Therefore, when multiple channels of video are displayed on a split screen in the terminal, when requesting video streams, the client and the server will perform signaling interaction through the Session Initiation Protocol when requesting each video stream to confirm the transmission of each video stream, The parameters required for playback, after which the server will establish a connection with the client to split the v...

[0003] Therefore, when multiple channels of video are displayed on a split screen in the terminal, when requesting video streams, the client and the server will perform signaling interaction through the Session Initiation Protocol when requesting each video stream to confirm the transmission of each video stream, The parameters required for playback, after which the server will establish a connection with the client to split the video stream. Since multiple videos need to be confirmed separately, the video of the front channel should be confirmed and displayed first, and the video of the rear channel should be confirmed first. After confirming and displaying later, when multi-channel video is played in split screen, the display time difference of each channel is large and the delay is problematic. Even if it is a multi-core and multi-threaded design framework, multiple threads process different video requests at the same time. Each thread The video request load undertaken is still high, resulting in delays in video display
