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...

[0002] For image monitoring systems, users often put forward some special requirements for the use environment. They hope to be able to monitor objects at a relatively long distance. These objects may be power grids in deep mountains, oil wells in wasteland, or other important equipment that is unattended or inaccessible. On the other hand, they want to obtain clearer images, and they have higher requirements for real-time image transmission. Obviously, it is difficult to meet such requirements with traditional PCs and image acquisition cards.
