H.264-based embedded wireless video monitoring system

Abstract

The invention discloses an H.264-based embedded wireless video monitoring system which is composed of a wireless terminal user or wired Internet monitoring user, a center server and an embedded monitoring terminal, wherein the wireless terminal user or wired Internet monitoring user is used for sending a user request command to the center server, the user request command firstly accesses the Internet by virtue of a CDMA (code division multiple access) gateway and then reaches the center server; the center server is used for carrying out command analysis after receiving the user request command, then sending a control command to the monitoring terminal through a wireless network; and the monitoring terminal is used for shooting field images by virtue of an image acquisition module after receiving a monitoring task sent by the center server, then sending image data subjected to H.264-based compression coding back to the center server by a CDMA module according to an RTP (real time protocol) communication protocol. By implementing the embodiment of the invention, the video signal acquisition, compression and transmission functions are achieved, and the compression coding efficiency is greatly improved.

Description

Technical field

[0001] The invention relates to an implementation method of an embedded wireless video monitoring system, in particular to a wireless video monitoring system based on a new generation of video compression standard H.264, which is oriented to wireless networks and the Internet. Background technique

[0002] For image monitoring systems, users often put forward some special requirements for the use environment. They hope to monitor objects that are far away. These objects may be power grids in deep mountains, oil wells in wastelands, or other important equipment that is unattended or inaccessible to people. Where; On the other hand, they hope to obtain clearer images, and at the same time, they have higher requirements for real-time image transmission. Obviously, it is difficult to meet this demand with the traditional PC and image capture card. Summary of the invention

[0003] Based on the shortcomings of the existing technology, the purpose of the present inventio...

Examples

Embodiment Construction

[0016] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] The structural diagram of the embedded wireless video monitoring system based on H.264 in the embodiment of the present invention is as attached figure 1 As shown, the system is composed of wireless or wired Internet monitoring users, a central server, and an embedded monitoring terminal. Wireless terminal users or wired Internet users send user request commands to the central server, first access the Internet through a code division multiple access gateway, and then reach the central server. After receiving the user's command, the central server analyzes the command, and then sends the control command to the monitoring terminal through the wireless network. After the monitoring terminal receives the monitoring task from the center, it w...
