Problems solved by technology

[0006] Aiming at the deficiencies of the existing technology, the present invention aims to provide a method for previewing GB / T28181 standard monitoring video across browsers based on the WebRTC protocol. Under the framework of the GB / T 28181 standard protocol body, the GB / T 28181 standard protocol is compatible with the WebRTC technology protocol. GB / T28181 The adaptation scope of the software application of the T 28181 standard extends to multiple operating system platforms such as windows and andorid and the multi-browser environment such as Chrome and Firefox, which solves the problem that the software application of the GB / T28181 standard cannot meet the real-time requirements of video surveillance on-demand. Effectively adapt to multi-operating system platforms such as windows and andorid and multi-browser environments such as Chrome and Firefox; at the same time, it also solves the incompatibility with GB / T 28181 protocol and the inability to achieve large concurrent audio in standard end-to-end WebRTC video and audio live broadcast scenarios On-demand request media stream problem

Embodiment 1

[0043] This embodiment provides a method for previewing GB / T28181 standard monitoring video across browsers based on the WebRTC protocol, such as figure 1 shown, including the following steps:

[0044] S1. The GB / T 28181 video and audio acquisition equipment registers with the SIP signaling server of the GB / T video surveillance networking platform through the GB / T 28181 standard SIP protocol;

[0045] The SIP proxy conversion server of the WebRTC access proxy service registers with the SIP signaling server of the GB / T video surveillance networking platform through the GB / T 28181 standard SIP protocol;

[0046] The WebRTC terminal device registers or logs in to the WEB service server of the GB / T video surveillance networking platform through the HTTP protocol, and the WEB service server of the GB / T video surveillance networking platform serves as the WebRTC terminal device according to the load of one or more WebRTC access proxy services managed. Dynamically allocate the entra...

Embodiment 2

[0060] This embodiment provides an example of applying the method of Embodiment 1 to the Internet public network environment, relying on the Internet public network network to realize the aggregation of media streams of GB / T 28181 video and audio acquisition equipment and the WebRTC end playback preview.

[0061] In this embodiment, the operating environment parameters of each main software and hardware node are as follows, such as figure 2 Shown:

[0062] (1) Main core servers such as streaming media server, WEB service server and SIP signaling server of GB / T video monitoring networking platform run on general hardware servers from manufacturers such as Huawei, Inspur and Sugon, and the operating system is CentOS6.5 and above , connect to the operator network provided by operators such as China Unicom and China Telecom through a network cable to access the Internet public network, and bind the addressable IP address of the Internet public network provided by the telecom oper...

Embodiment 3

[0082] This embodiment gives an example of applying the method of Embodiment 1 to a non-Internet public network industry video private network environment, relying on the video private network network to realize the convergence of media streams of GB / T 28181 video and audio acquisition equipment and WebRTC end playback preview .

[0083] In this embodiment, the operating environment parameters of each main software and hardware node are as follows, such as image 3 Shown:

[0084] (1) Main core servers such as streaming media server, WEB service server and SIP signaling server of GB / T video monitoring networking platform run on general hardware servers from manufacturers such as Huawei, Inspur and Sugon, and the operating system is CentOS6.5 and above , connected to the video private network switch through 10 Gigabit optical fiber, and bound to the video private network addressable IP address provided by the video private network operator;

[0085] (2) The main core servers ...

Abstract

The invention discloses a method for previewing a GB/T28181 standard monitoring video of a cross-browser based on a WebRTC protocol. According to the method, on the premise of ensuring the real-time requirement of video monitoring on demand, the software application adaptation environment of the GB/T28181 standard can be expanded to the multi-operating system platforms, such as windows, android, etc., and the multi-browser environments, such as Chrome, Firefox, etc., meanwhile, the compatibility with a GB/T 28181 protocol and a large concurrent audio on-demand request media stream function ina standard end-to-end WebRTC video and audio live broadcast scene are also realized. According to the method, the GB/T28181 standard video monitoring on-demand real-time performance can be guaranteed,and meanwhile the software application environment based on the GB/T28181 standard is wider in use environment and higher in environment compatibility.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a method for previewing GB / T28181 standard monitoring video across browsers based on the WebRTC protocol. Background technique [0002] The GB / T28181 standard is the most widely used and most influential national standard for video surveillance networking in the domestic security industry. Due to cross-operating system platforms (including windows, linux, mac, and android, etc.), cross-browser (including Chrome, Firefox, and Internet Explorer) etc.), the software terminal display form of the application system based on this standard is mainly a desktop application on a multi-operating system platform such as windows or an ActiveX plug-in application based on the Internet Explorer browser. [0003] The WebRTC protocol is one of the most mainstream, cross-platform, cross-browser, and real-time protocol standards in the Internet video industry. The application system based on thi...
