Product Overview

The GEOSATpro DSR180QAM IRD integrated receiver decodes high definition and standard definition video. The DSR180QAM is capable of receiving signals from variable program sources including DVBS, S2, DVB-ASI, IPTV (RTP, UDP, RTSP) QPSK and support for 4:2:0 chroma. Output interfaces include CVBS, HDMI, AES/EBU HD/SDI, ASI and QAM64/QAM256. This decoder integrates a QAM HEADEND.

The DSR180QAM has 2 common interface slots capable of decrypting multiple channels. With the LAN control and monitoring function by remote web-based management and front panel controls, this user-friendly decoder is ideal for signal conversion and distribution for SD or HD-based digital video head-end system. 

This receiver is a great solution as a complete Headend unit that can receive 2 Satellite transponders and other ASI or IP streams and distribute them to ATSC QAM television sets simultaneously broadcasting all channels. Simply split the signal and it's one unit solution for Care Centers, Multiple Unit distributions, Condominiums or Apartments. You can also add local terrestrial receivers for local channels to be added to the distribution. Contact us for details.
