Product Description


DMB-9581 H.264 HD Encoding Modulator (all-in-one) is a high-density and flexible device, integrating Encoding, Multiplexing, Encapsulation and Modulation with its excellent performance of HD encoding and modulation. It supports various of modulation modules, such as DVB-T module, DVB-C module, ATSC-T module, DTMB module and ISDB-T module, etc.. The device is designed in standard 1U chassis, with a max. capability of swapping two modules(Encoding module or WIFI module or Tuner in module by option). Meanwhile, it delivers unrivaled and reliable video quality with advanced video compression(H.264) technology, to meet the ever-increasing need of high quality video experiences. Moreover, with its multiplexing module, local programs can be re-multiplexed with external Transport Stream. Additional, DMB-9581 can be applied to IPTV system with TS over IP output. The device also supports program sources from video and surveillance control camera or HD STB, HD camera or playout server, PC and other diversified video source.
