IP視頻節點、視頻服務和視頻矩陣用于很相似的需求。它們可以在像LAN、企業內部互聯網或互聯網這樣的 IP網絡中處理多視角輸入、數字化、壓縮和流數字媒體內容，并將模擬視頻系統轉換成網絡視頻系統。用戶可以通過網絡瀏覽器或應用軟件在網絡中的任何一個本地或遠程計算機上觀看實況圖像。使用者還可以遠程配置和控制。它允許授權的用戶在不同的地方同時存取從同一個模擬攝像機以及安裝在系統中的網絡攝像機上所獲得的圖像。這些設備還可以選擇的存取視頻,并作為獨立的單元進行工作。

數字視頻傳輸正快速適應安全和監控系統的標準要求。TI公司的DSPs使開發人員可以靈活的設計各種數字監控產品。借助DSP的可編程性、處理性能、視頻專用外設及支持所有主流多媒體的編譯碼器，開發人員可以設計出具有定制特性的不同產品以滿足不斷變化的市場的需求。

下面對元器件的性能和方框圖進行描述：

TI&rsquos video surveillance solutions are primarily based on the high-performance DM64x&trade DSP-based digital media processors. The DM64x DSP-based digital media processors have on-chip video ports for easy connection to video devices and are capable of handling both video and audio encode and decode for IP-based video surveillance applications. The single, programmable digital media processor is a cost-effective solution because the need for external PCI or EMAC is eliminated.
