Overview
DMB-9580 MPEG-2 24-Channel SD Encoder is a broadcast level encoding platform that adopts advanced compression technology with features of ultra-low bit rate and low latency. It can provide high quality images even at low bit rate. DMB-9580 is integrated with 24 channels. Provided with an external 2*ASI input, it can be multiplexed with the local multi-programs to eliminate the needs of multiplexers, and also cascading with several encoders, to simplify the network architecture for high reliability solutions. The device supports output interfaces of ASI and IP(TSoIP) out, while the TS over IP out provides 1*MPTS or 24*SPTS over IP change by software. DMB-9580 is coupled with user-friendly NMS, to be easily upgraded via software to add new functions or improve features and enhance performance. It is the preferred device for DTV service providers and customers for its unrivaled performance, flexibility, advanced compression and high affordability per channel.
