基于DaVinci技术的嵌入式Web视频监控系统的设计
Design of embedded Web video monitoring system based on DaVinci technology
摘要
Abstract
Based on the newly developed DaVinci technology, a designing scheme of embedded Web video monitoring system is proposed. The scheme combines high-speed and dual-core signal processor (TMS320DM6467) with embedded Linux operating system as the platform to complete the H.264 encoding, transmission and storage of video signal. Building the embedded Web server, user can login into the server and monitor at real-time. According to the method of rate-distortion optimization, an improved rate control algorithm is proposed. The algorithm can significantly improve the coding rate of video stream and the coding quality. It is proved that the average bit rate error of the proposed algorithm is 1.2%lower than that of the JVT-G012 algorithm. Besides, the signal to noise ratio is improved by 1.16 dB. This system has advantages of strong real-time, interactive and high video quality so that it can be used for remote video surveillance.关键词
