High-definition wireless video transmission system with wireless video transmission module and GPS positioning module

Abstract

The invention discloses a high-definition wireless video transmission system with a wireless video transmission module and a GPS positioning module, and belongs to the technical field of wireless video transmission and monitoring control equipment systems in the field of electronic information. The high-definition wireless video transmission system comprises a digital acquisition circuit and a program control circuit, wherein the digital acquisition circuit consists of a protection circuit, a sampling hold circuit, a high-speed A / D converter and a digital buffer; an AV signal acquired by a camera is input to a video / audio signal digital acquisition circuit, and an analog AV signal can be digitally acquired under the coordination of the program control circuit. According to the system, the code rate can be saved by about 50 percent, the network adaptability is high, the error recovery capacity is improved, and the system can well adapt to the application of an IP and a wireless network.

Description

technical field [0001] The invention relates to the technical field of wireless video transmission and monitoring control equipment system in the field of electronic information, specifically a high-definition wireless video transmission system with a wireless video transmission module and a GPS positioning module. Background technique [0002] With the continuous improvement of the degree of social informatization, the range of remote video surveillance that needs to be implemented in all walks of life in society has greatly increased. From traditional security monitoring to management monitoring and production and operation monitoring, the requirements for remote video monitoring systems are also increasing. Often It needs to be combined with the network system to realize real-time and non-regional transmission of a large amount of video data, so as to achieve resource sharing and provide convenient, fast and effective services for managers and decision makers at all levels...

Problems solved by technology

At present, video surveillance generally has poor image quality, low resolution, frame skipping and mosaics during wireless transmission, and it is impossible to achieve a clear monitoring effect, let alone high-definition monitoring.

As a result, we often see wanted information broadcast on TV in some banking and traffic cases. Neither the police nor the audience in front of the TV can clearly see the specific characteristics of the suspect or the vehicle, which cannot meet the requirements of case detection for image clarity. Requirements, (recognition of image content details) especially post-processing such as local amplification, analysis and identification of surveillance images, to provide specific characteristic materials or scientific analysis materials for surveillance. At present, most surveillance systems in my country cannot do this. Analytical work carried out with very limited support
