Embodiment Construction

[0021] Such as figure 1 with 2 Shown, the concrete implementation method of the present invention is as follows:

[0022] (1) Obtain front-end video image data

[0023] Such as image 3 As shown, the front-end camera video is captured by acquisition devices such as video server, hard disk video recorder, and capture card, and each video is decoded by using the software development kit (SDK) provided by different manufacturers to obtain the original image data in YUV format or RGB format .

[0024] (2) Compilation of unique spatial identification number (ID) and unified time tag (TS)

[0025] According to the unique number of the front-end camera, the unique identification number (ID) of the three-dimensional space of the front-end multi-camera video is compiled;

[0026] According to the regional system time provided by the external clock or the time service system, a regional unified time tag (TS) is prepared for each frame of video image data of each camera.

Abstract

The invention relates to an intelligent video information distribution and coding method. The method is implemented by the following steps that: an area three-dimensional space unique ID is complied for a front multipath camera video and an area unified TS is compiled for video frame data according to an area system time reference; coding is carried out on obtained any path of video information frame according to information of the area three-dimensional space unique ID and the area unified TS, so that coding frame data volumes are formed; and intelligent distribution and fusion are carried out on all the coding frame data volumes according to a demand of a client and a network bandwidth situation so as to obtain a synthesized serialized video data volume; and a network transmission protocol is employed to carry out serial flow transmission on the synthesized video data volume.

Description

technical field [0001] The present invention relates to the field of information processing and encoding, in particular to an intelligent video information distribution and encoding method, which is mainly used in multi-channel video monitoring and video transmission technology to realize redistribution and encoding of multi-channel video information in the monitoring area, Flexible transmission of video. Background technique [0002] With the development of economy and technology, people have put forward higher requirements for the safety of living and office environments, resulting in the gradual increase of the capacity of a single individual video surveillance system, requiring large-scale networked video surveillance represented by "Safe City" The system integrates scattered social video surveillance resources to realize the interconnection, intercommunication and mutual control of various systems. Especially for the safe operation and protection of key facilities or a...
