| 企業網路視訊廣播系統(Live
H.264 SD encoder) |
|
|
 |
產品特色：
-
能完成720x480(Full
D1)的影像和立體音訊的擷取，採用ISO/IEC國際認證標準MPEG-4
Advanced
Simple Profile/H.264
Part 10(with
B frames)與AAC的壓縮方法，能即時將影像和聲音同步編碼，並透過網路系統廣播出去，可提供數百到數千人同時觀看，是一個完整的企業視訊廣播系統解決方案。
-
採用前置端影像處理，可加強影像/聲音輸出效果，並具有影像濾波功能，完整支援PAL和NTSC視訊格式。
-
採用H.264壓縮系統。在今天是能使影像和聲音頻寬減小的最好的標準，能使在數位網路上需要大頻寬的影音，例如：網路電視、視訊會議、遠距訓練和監視系統都能像離線觀看時一樣擁有即時和高品質的影音。
-
也可以應用在安全與監控系統上,做即時的影像監控。
-
此套件擁有許多所需要的功能，可以輕易的研發高階具有高附加價值的產品。
