Embodiment Construction

[0035] In the following, the video streaming method of the present invention will be described in detail through specific embodiments in conjunction with the accompanying drawings. The following embodiments are only descriptive and not restrictive, and therefore cannot limit the protection scope of the present invention.

[0036] In the present invention, the client and the decoder are both clients in a broad sense, that is, the term "client" includes the client, the decoder and various similar terminal devices. The reason why the background art part of this application distinguishes the client and the decoder is because under the existing heartbeat keep-alive mechanism, the two have different ability to achieve stability at both ends of the video stream, and using the video stream transmission method of the present invention, There is no difference between the two.

[0037] See image 3 , image 3 It is a schematic diagram of a video streaming method according to the present inven...

Abstract

The invention relates to a video stream transmission method and device. The video stream transmission method includes the steps of building a UDP socket, setting whether inner core detection has a mistake which can be immediately known or not, recording the IP address and the port number of an opposite end, then immediately executing the calling procedure, detecting the mistake in the calling procedure, setting a threshold value according to the field network condition to remove the possibility of erroneous judgment on video stream interruption caused by the network environment, and when a value is larger than the preset threshold value, closing the socket of a video stream, enabling the video stream to be not sent or received. According to the video stream transmission method and device, phenomena such as video series flow and video density current can be effectively avoided, the video stream transmission performance is improved, and the network transmission pressure is reduced.

Description

Technical field [0001] The invention relates to intelligent network video monitoring technology, in particular to a video stream transmission method and device. Background technique [0002] The main function of the streaming media server is to transmit the video stream to the client through the streaming protocol (RTP / UDP, etc.) for monitoring by the monitor; or send it to the decoder for the decoder to decode and use. [0003] Since the UDP protocol is an unreliable, connectionless and simple transmission protocol, the existing video streams cannot guarantee that the data can reach the destination accurately and reliably. Any asynchronous errors caused by the connectionless UDP socket in the transmission, The kernel cannot return to the process they are in. [0004] At this stage, in order to maintain the stability at both ends of the video stream, such as figure 1 As shown, the heartbeat keep-alive mechanism of the real-time stream is usually added when there is video stream tran...
