Abstract

The invention relates to a video monitoring and transmission device based on the TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) network, belonging to the technical field of video information transmission equipment. The video monitoring and transmission device comprises a video data acquisition unit, a video monitoring center and a user handheld device, wherein the video data acquisition unit comprises a core board circuit and a TD HSUPA (Time Division High Speed Uplink Packet Access) module, the core board circuit is connected with a camera, a pan/tilt decoder and the TD HSUPA module, and the acquisition and the compression of video signals and the packaging of streaming media data can be realized; the video monitoring center provides service for the transmission, the storage and the forwarding of video data in the network, transmits the video data to the user handheld device and realizes real-time monitoring; and the user handheld device realizes field real-time monitoring and remote pan/tilt control through system play software installed on the user handheld device. The video monitoring and transmission device has quick video information transmission, high quality, low cost, good application prospect and environmental protection.

Description

Technical field: [0001] The invention belongs to the technical field of video and electronic information transmission equipment, and relates to a digital video monitoring system in the field of mobile communication, in particular to a video monitoring transmission device based on a TD-SCDMA network. Background technique: [0002] The development of video monitoring and transmission system can be divided into three stages. Before the early 1990s, the closed-circuit television monitoring system based on analog equipment was called the first generation of analog monitoring system; in the mid-1990s, with With the improvement of computer processing ability and the development of video technology, the high-speed data processing ability of computer is used to collect and process video, and the high resolution of display is used to realize multi-screen display of images, which improves the image quality. This PC-based multimedia The main console system is called the second generatio...
