OVERVIEW

DMB-8900 MPEG-2/H.264 HD Universal Encoder features high performance, low latency and extremely low bit rates for DTV system, and adopts state-of-the-art compression technology for MPEG-2 and H.264 changing seamlessly. The DMB-8900 is equipped with diversified input interface, including HDMI, CVBS, YPbPr, HD-SDI, digital AES, unique Quad-Audio(balanced XLR and unbalanced L/R,as well as Audio embedded SDI) and Digital Dolby AC-3(2.0/5.1). Additional, it is simplify the Network architecture in carrying out high reliability solutions. Moreover, it has 1+1*ASI backup and 1*IP(UDP) output interfaces. The empty packets filtering capable of IP out not only enable to provide more services in the limited bandwidth, but also largely enhance the utilization of spectrum source of IPTV system.
