VMC-5400™提供高品質即時H.264/AVC/MPEG-4 Part 10壓縮編碼功能，採PCI設計，低CPU使用率，適用於Windows
2000/XP的作業環境
VMC-5400™採用多重DSP(數位信號處理器)架構，提供無比的靈活性，可升級能力及高量化能力的即時影像壓縮演算法
主要設計符合高標準要求的影音傳播應用環境，例如TELCO IP/TV解決方案
VMC-5400™提供下列影音輸入
-數位輸入：Video (SDI)和 Audio (embedded
SDI及Separate
AES / EBU)
-類比輸入：Video (YUV，RGB，S-Video，Composite)和Audio (balanced
and unbalanced stereo)
VMC-5400™支援MP＠L3影像解析度由QCIF至FD1(720X480X30fps或7207x576x25
fps)
，MPEG串流位元率可調整由64Kbit/s至10Mbit/s
VMC-5400™提供超強功能包括：
--CABAC (Powerful option
which achieves higher compression ratio)
--Pause/Resume
--Split mode (consecutive
frame accurate files generation of a defined length)
--Preview video on the host
screen
--Audiometer overlay
--Capture still image while
encoding
--Streaming option
VMC-5400™包含易學且能快速整合功能強大的SDK (Software
Development Kit) SDK依據Livewire架構設計。能完全配合您的應用需求
