Problems solved by technology
[0004] The above-mentioned video stream forwarding system sets a video stream forwarding device between the client and the sending source, which can reduce the transmission delay of the video stream, but it still needs to establish an end-to-end connection relationship between the client and the sending source, and the port of the sending source cannot be realized. Multiplexing cannot solve the problem that the three-bit application of the digital converter station penetrates the intranet

Embodiment Construction
[0041] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0042] refer to figure 1 , in some embodiments, a video stream forwarding system for a converter station is provided, including: a video stream gateway server 1, a signaling server 2, an access terminal 3, a NAT firewall 4, and a plurality of push stream servers 5;
[0043] The access terminal 3 is used to establish a communication connection with the video streaming gateway server 1 and the streaming server 5 through the signaling server 2. After the communication connection is established, the video streaming gateway server 1 provides a unique gateway port for the access terminal 3;
[0044] The access terminal 3 is also used to send the video request to the NAT firewall 4, and the NAT firewall 4 is used to convert the video request and send it...

The invention discloses a video stream forwarding system and method for a converter station. The system comprises a video stream gateway server, a signaling server, an access end, an NAT firewall and a plurality of stream pushing servers. The access end is used for establishing communication connection with the video stream gateway server and the stream pushing server through the signaling server, and after the communication connection is established, the video stream gateway server provides a unique gateway port for the access end; the access end is further used for sending a video request to the NAT firewall, the NAT firewall is used for converting the video request and sending the video request to the video stream gateway server through the gateway port, and the video stream gateway server is used for carrying out protocol packaging processing on the video request and sending the video request to the corresponding stream pushing server. After the corresponding stream pushing server receives the video request, the video stream is sent to an access end through a gateway port of a video stream gateway server; according to the invention, single-end multiplexing of the plug-flow server can be realized, and all data flows out through the same port.
Description
technical field [0001] The present invention relates to the technical field of video stream forwarding, in particular to a video stream forwarding system and method for converter stations. Background technique [0002] The 3D application of the digital converter station needs to adopt the method of video streaming. Because it involves multi-channel call requirements, at least 10 or more 3D concurrent streaming needs to be guaranteed. However, in order to ensure the security of the intranet, power grid companies have strict restrictions on the number of open ports, and cannot open more than a dozen gateway ports. This makes the 3D application of the digital converter station unable to penetrate the intranet for use. In addition, when managing multiple ports, each port has a certain performance overhead, so the increase in ports will also lead to a certain degree of decline in server transmission performance. [0003] At present, there are many kinds of video stream forwardin...
