DMB-8820E Series Multi-Channel HD RTMP/HTTP/RTSP/HLS/SRT Encoder
DMB-8820E Series Multi-Channel H.264 /H.265 HD Encoder features high performance, ultra-low latency and low bit rates for DTV systems, and adopts state-of-the-art compression technology (H.264/AVC-H.265/HEVC) to achieve compression efficiency of the former MPEG-2 standard by over two times, as well as excellent resolution. Also audio encoding supports MPEG-1 Layer2.
The device provides input interfaces of 4/8/12/16/20/24 HDMI, and ASI output and 512*SPTS/8*MPTS TSoIP(UDP/IP) and supports RTMP/HTTP/RTSP/HLS/SRT protocol output after loss-less compression processing. The unique empty packets filtering capability enables the spectrum source to be saved for IPTV systems.
DMB-8820E has an external 2*ASI input, which can be multiplexed with local multi-programs to eliminate the needs of multiplexers, and also simplify the network architecture for high reliability solutions. DMB-8820E Encoder is the preferred device for content source encoding of DTV broadcasting system to address the ever-increasing demand for more premium viewing experiences.
