摘要
现代社会急速向信息社会发展,而多媒体技术是信息化中主要的技术环节之一,它已渗透到各学科领域和国民经济的各个方面。网路摄像机作为多媒体的主要内容,得到广泛的研究和应用,同时也推动了Internet网络,无线移动网络相关的通信技术的发展。数字信号处理器(DSP芯片),作为快速和实时处理的最重要的载体之一,也得到了广泛的应用。ISO/IEC和ITU推出的音视频编码方面的一系列标准,如H.261、H.263、H.264等,为视频通信提供了前提。论文将网络摄像机硬件系统及其实现技术作为课题的研究内容,介绍了基于TMS320DM642SDSP网络摄像机的硬件实现方案。本硬件系统可广泛应用于数字监控系统、视频会议、可视电话等领域。
Multimedia is the principal technology in informatization, Network camera, as the main content of the multi-media technology, is deeply studied and widely applied, and thus promotes the development of the Internet and wireless mobile communication technologies. DSP, as the carrier of high-speed and real-time processing, also achieves wide-spread application. A series of audio-video coding standards put out by ISO/IEC and ITU, such as H.261, H.263 and H.264, have provided guarantees for video communication. This paper describes the studies on the network- camera hardware system and its implementation scheme of TMS320DM642SDSP-based network camera. This hard-ware system may be widely applicable to digital monitoring system, video conference, videophone and other domains.
