Problems solved by technology

While using high-configuration hardware to solve efficient transmission, it also brings defects such as long system development cycle, low software reuse rate, expensive overall system hardware, and high system failure rate.
[0005] To sum up, the existing real-time video monitoring methods can no longer meet the requirements of low hardware complexity, high operating efficiency, and high network bandwidth utilization, and a method is needed to realize efficient transmission of high-definition real-time video under lower hardware configuration conditions.

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation.

[0025] This embodiment includes the following steps:

[0026] Collect the video data of all cameras, decompose the video data of each camera into continuous single-frame images, and store each frame of images in the first-level cache allocated separately for each camera; then store the image data in each first-level cache Move to the second-level cache as the image data warehouse of all first-level caches; after receiving the request to extract the video content of the corresponding camera and being accepted to start execution, create a corresponding third-level cache and request the corresponding second-level cache The image data in the third-level cache is moved to the third-level cache, and the image data in the third-level cache is continuously sent until the end of the request, and finally the third-level cache is ended to rel...

Abstract

The invention discloses a high-definition real-time monitoring video efficient transmission method. The method is realized on the basis of an ARM video transmission board by adopting a multi-input multi-output system of technologies of multi-thread processing, multi-level data caching, high-concurrent mutual exclusion access and the like. The hardware mainly comprises the ARM video transmission board, a USB high-definition camera and a power supply module; and the software treating process mainly comprises a multi-camera input part, an image data warehouse and a multi-request output part. The method occupies a few resources, is efficient in operation, can guarantee the quality and the instantaneity of high-definition real-time video, and is applicable in the field of real-time video monitoring, particularly in the fields having high efficiency requirement, limited hardware resources and efficient software method requirement.

Description

technical field [0001] The invention relates to the field of real-time video monitoring, in particular to an efficient transmission method of high-definition real-time monitoring video. Background technique [0002] As an important part of industrial monitoring and safety monitoring, real-time video monitoring system is widely used in factories, banks, roads and residential areas with its rich forms of intuitive traversal. Real-time video monitoring system is usually composed of video acquisition, transmission, display and other parts . [0003] In some occasions where cost reduction is serious and efficiency requirements are strict, such as mountains, deserts, etc., on the one hand, due to the large area, there are many requirements for monitoring nodes, and the configuration of the device used is too high, which will easily lead to rapid consumption of internal energy in the device and increase the overall cost. . Therefore, the cost of a single monitoring node is requir...
