Embodiment Construction

[0035] 1. System structure:

[0036] The system modules of the present invention adopt a loosely coupled hierarchical design, and the communication mechanism between the system modules completely adopts a hierarchical structure, so new functions can be added conveniently, and existing ones can also be easily upgraded. The function of the system, the frame diagram of the system is as follows figure 1 shown. The user can request the IPTV terminal to enable the home video monitoring function through the Internet through various devices with browsers, such as smart phones, desktops or laptops. The architecture diagram of the present invention is as follows figure 2 shown. After the user logs in to the browser, the user information is authenticated first. When the input data matches the user information stored in the IPTV terminal, the Thttpd server responds to the user's request and calls the V4L2 driver to collect video data; use Da Vinci The DSP core of the platform perform...

Abstract

The invention aims to provide a video monitoring system based on DaVinci technology and an implementation method thereof. The invention can enable users to remotely monitor family information conveniently and visually in a webpage mode through network interactive television terminals, and solves the problems of high power consumption, instability, difficult installation and maintenance and the like of the traditional video monitoring system. In the invention, a video driver of an operating system is used for acquiring and outputting videos; a digital signal processor core is used for carrying out image hardware encoding in the format of dynamic joint photographic expert group (JPEG) on video data; a real-time transport protocol (RTP) library with open sources and a congestion control method are used for realizing stable and reliable data transmission; the interaction between a user and a network interactive television terminal is realized by transferring a quick and stable webpage server; and controls embedded in user browsers are used for realizing dynamic display of images. Meanwhile, the system also has the advantages of strong expansibility, high reliability and stability, low power consumption, small investment, wide market application prospects and the like.

Description

technical field [0001] The present invention is a home video monitoring system based on Da Vinci technology and its implementation method. Home users can conveniently realize remote video monitoring functions through IPTV (Interactive Personality TV) terminals using Da Vinci technology After passing the identity authentication of the embedded Web (webpage) server, the IPTV terminal can return to the interface of the monitoring system for the user to remotely monitor the situation at home. It belongs to the application field of video surveillance. Background technique [0002] The video surveillance system is an integral part of the security system and a comprehensive system with strong prevention capabilities. It is widely used in many occasions because of its intuition, convenience and rich information content. But the video surveillance system we mentioned now generally refers to industry surveillance, such as banks and public security departments, and the number of fami...
