IP Camera 參考設計平台


IP Camera 參考設計平台 提供一個完整、靈活的硬體和軟體平臺。參考設計支援Nexperia PNX1502 多媒體處理器,以提供優質的video和audio的編碼。


硬體的基本的方塊圖,提供libraries和應用範例准許容易的建立一個working video/audio streaming device 。同時, 因為提供的媒體處理器成分遵守被證明的NDK/TSSA Nexperia 程式標準,參考設計平台提工製造商客戶化解決能力、 集合各式各樣的影像處理函數到定製的韌體,如此解除網路並且/或者中央伺服器資源藉由"on-site" intelligence提供(像一些定製的圖像增強演算法、事件觸發等)。
