Abstract: This paper introduces a MPEG-4 based video card. This 4-channel PCI card compresses the input analogue image signals using MPEG-4 technology, and communicates with CPU console board under PCI2.2 specification. The CPU console board can access the internal registers of the encoding chip through a bridge circuit,and get the compressed video and audio streams from it.The card also has a notable feature of image preview. It adopts the newest MPEG-4 technology, and provides the hardware foundation of remote real time monitoring and network transmitting systems,so it has a comprehensive market prospect.ADF4113BRUZ

在过去相当长的一段时间内,传统的模拟闭路电视监控系统是场所监控的市场主流产品。ADF4113BRUZ但随着信息技术的发展和用户需求的提高,模拟闭路电视监控系统暴露出一些缺陷。主要表现在:传输距离不可能很远、无法远程监视、布线工程量大,特别不适应信息时代的数字化发展趋势。而数字化监控系统的优点恰好克服了模拟闭路电视的局限性,如网络传输视频流、传输距离远、布线不重复、抗干扰能力强、远程监控、查询方便等。
