Streaming Media Compressor
HVC400 is a MPEG-4 hardware Video compressor of high efficiency,top-quality, stability. Video signal can be encoded into WMV, DIVX,MPEG-1, MPEG-2 etc format files or streams by using this card. It'sperfect applies on video recording and casting. Because of thehardware compression, it saves the PC system resource as much aspossible, quadruple HVC400 cards can be easily and stably run on anormal PC. The NOWSTREAM software with HVC400, supports most of 4cards. Each channel runs independently different video size as wellas bit rate.
It's also an ideal choice for the high-definition requirement, forit can reach the DVD video quality at 2Mbps low bit-rate. It widelyapplies in the IPTV, Video Meeting, Long-Distance Education,etc.

Applications:
1, Video Meeting
2, DVD, VCD creating
3, Network streaming publishing
4, Video file recording
5, Long-Distance education
6, Long-Distance security
