MPEG-4-2-1即時壓縮卡/VM系列(SDK)
VM MPEG-4-2-1即時影音壓縮卡
VM系列影音壓縮卡提供低價位.高品質MPEG-4-2-1即時編碼壓縮.符合工業標準及專業應用領域
VM系列產品採用VITEC技術領先全球的VM200晶片設計,並開發完成下一世代的MPEG 壓縮技術Hybrid
Technology.此一技術讓您不用擔心硬體投資的浪費,未來只要透過Soltware的更新,就能持續與世界標準同步,而不落伍或被淘汰
Hybrid技術帶給您的利益
1.隨著時間的演進能增強執行效能及功能
愈快速的pc將能不斷提升至較高的品質及增加新功能,目前市場上没有其它產品有此一功能
2.簡單且經濟的更新
硬體架構永遠不便,可完全靠軟體更新規格,保障硬體投資及低成本的更新至新世代規格產品
3.增加產品使用年限
當每一世代技術來到市場時,不需要花錢及時再開發一次產品
4.一致性的安裝基礎
VAR或SI能提供一致性的安裝環境給客戶容易維護
5.低成本效益
Hybrid技術須要較少的矽晶体相對的耗電量也低,整体成本較低
