Wireless transmission video monitoring system and method

Abstract

The invention discloses a wireless transmission video monitoring system and a wireless transmission video monitoring method. The system comprises a video acquisition module, a video digital signal coding module, a network sending adaptive module, a control transmission module, a video receiving decoding module and a monitoring terminal, wherein the video acquisition module is used for acquiring video data through a video acquisition terminal; the video digital signal coding module is used for acquiring the video data acquired by the video acquisition module and compressing and coding the video data by using an image group bit distribution method and a foreground-background decomposing and coding method; the network sending adaptive module is used for adaptively selecting a network environment aiming at different network environments of gateway routing equipment to perform communication; the control transmission module is used for managing network state reports generated by each independent network monitoring; the video receiving decoding module is used for receiving real-time video data from a network, identifying the source of each path of video data in multi-path transmission and analyzing and decoding the received video data; and the monitoring terminal is used for acquiring the decoded real-time video data and playing the decoded real-time video data through a player. The scheme of the invention can perform good wireless transmission under a narrowband network environment.

Description

Technical field [0001] The present invention relates to the field of video technology, in particular to a wireless transmission video monitoring system and method in a narrowband wireless network environment. Background technique [0002] With the rapid development of science and technology, home safety of various science and technology products is related to the safety of people's family and property. It has always been a major concern of people. Video surveillance systems have become a necessary device for home safety considerations. [0003] The digital video signal has the following characteristics: [0004] (1) Large amount of data [0005] Mobile video phones generally use QCIF (quarter common immediate format, quarter common immediate format) resolution images, which have 176X144=25344 pixels. If each pixel is represented by 24 bits, the data volume of one frame of image still reaches 594kbit. Taking into account the frame rate required for real-time video image transmission ...

Problems solved by technology

[0006] (2) High real-time requirements

[0008] Due to the limited wireless channel resources in the wireless network environment, if it is necessary to realize the transmission of video signals with a large amount of data, especially in wireless visual applications for the public, the wireless channel resources may be insufficient. In addition, in mobile communications, users The mobile QoS guarantee of wireless video is very complicated

[0009] Therefore, it can be found that in the prior art, there is a sharp contradiction between the need for video signal transmission and the characteristics of the wireless environment, and the existing wireless transmission video monitoring method needs to be improved.
