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

在過去相當長的一段時間內,傳統的模擬閉路電視監控系統是場所監控的市場主流產品。ADF4113BRUZ但隨著信息技術的發展和用戶需求的提高,模擬閉路電視監控系統暴露出一些缺陷。主要表現在:傳輸距離不可能很遠、無法遠程監視、布線工程量大,特別不適應信息時代的數字化發展趨勢。而數字化監控系統的優點恰好克服了模擬閉路電視的局限性,如網絡傳輸視頻流、傳輸距離遠、布線不重復、抗干擾能力強、遠程監控、查詢方便等。
