Problems solved by technology

[0004] In general security control management software, the video recording equipment in the front section has been recording in real time, and the video is stored in the hard disk of the recording host. The central client will pop up a warning of the alarm point through the alarm network system to remind the relevant operation and maintenance personnel to pay attention. If the operation and maintenance personnel want to view the video of the alarm just now, they need to remotely download the video stored in the hard disk of the front-end network video host, and also need to find The footage from the time of the accident, making the process of finding and downloading cumbersome and inefficient

Embodiment Construction

[0017] A real-time transmission method of video recording buffer, comprising the steps of:

[0018] 1. The front-end data acquisition equipment collects and saves audio and video data in real time; at the same time, it transmits to the streaming media server through the network. The front-end data acquisition equipment includes various types of digital hard disk recorders (DVR), network video recorders (NVR) and network video surveillance systems (IPVS); when the streaming media server starts, it will automatically connect to the specified video channel according to user configuration, and obtain Audio and video data; the streaming media server has opened up enough buffer space for each video channel to ensure that the server can cache streaming media data for a certain period of time; streaming media data transmission adopts TCP / IP protocol.

[0019] 2. When an alarm occurs, the front-end alarm equipment (which can be an alarm host, a hard disk video recorder, various detecto...

Abstract

The invention discloses a real-time transmission method for video record buffering, which adopts a buffering storage technology to cache the data of each video channel, and when an alarming signal is input, a stream media server intercepts the video image before a certain period of the alarming triggering time point from the cache automatically to be spliced with the video image after the alarming triggering time point. The invention has the advantages that the on-site situation when alarming can be actually restored in time; a client display assembly provided by a monitoring management platform can help the user to handle various emergencies conveniently so as to effectively increase the working efficiency of the user; and the speed and the efficiency for playing back the on-site video records by the operation and maintenance personnel are greatly increased so as to react to the accidents in time.

Description

technical field [0001] The invention relates to the field of transmission and processing of video images in the monitoring field, in particular to a real-time transmission method of video recording buffer. Background technique [0002] Bank security systems have been built for many years. With the continuous advancement of science and technology, various security products and security control management software are also emerging, presenting the status quo of "a hundred flowers bloom and a hundred schools of thought contend". [0003] In the past, bank video recordings were stored in district and county-level monitoring centers to achieve unified recording and storage of monitoring images, and the superior monitoring center can remotely query and call video information. At this stage, the video system management software is installed on the management host of the municipal monitoring center. Through the connected PC monitor, analog monitor or matrix TV wall, not only can the...
