Embodiment Construction

[0017] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0018] With the development of WEB technology, video surveillance technology is also advancing with the times. In terms of video playback, HTML5 specifies a standard method to include video through the video element. This element supports the playback of real-time video streams in HTTP protocol OGG format, MPEG4 format, and WebM format. The video is clear and smooth, and the CPU usage is low. In terms of video transmission, the emergence of ONVIF and RTSP protocols has unified the communication specifications between network video clients and video transmission equipment of various manufacturers. This protocol makes it possible for products provided by different manufacturers to communicate through a unified interface. Its advantages are: 1. Synergy, pr...

Abstract

The invention provides a visualization system and method based on a RTSP / ONVIF protocol. The system comprises a real-time video stream acquisition module used for connecting a camera and extracting a real-time video based on the RTSP protocol and in a h.264 format according to a preset RTSP address of the camera and a preset encoding format, and converting the real-time video into real-time video stream based on the HTTP protocol and in an Ogg format; a video playing module used for playing the real-time video stream in the Ogg format in a video playing interface, wherein at least one video player embedded in the video playing interface is arranged in the video playing interface, and a tag and an attribute value of the video player are embedded in the video playing interface; and a tripod head control module used for sending a control instruction based on a ONVIF protocol to a tripod head used for loading the camera.

Description

technical field [0001] The invention belongs to the technical field of electric power system online monitoring, and in particular relates to a visualization system and method based on RTSP / ONVIF protocol. Background technique [0002] The power system is undoubtedly one of the most important parts of modern life, and a stable power system is the guarantee for people to live and work. In the field of power transmission, it is very important to ensure the reliability of transmission lines, and visual monitoring is an intuitive monitoring method that has been widely used in the power field. The existing visualization systems are all built through the private protocol of the video equipment manufacturer and play the video through the ocx plug-in on the browser. The advantage of this system architecture is fast speed, but it also has the following disadvantages: 1. The compatibility of the system is poor due to the different private protocols of various manufacturers; 2. The com...
