The Thor HDMI to QAM modulators combine HD hardware encoders with a multiplexer and agile QAM modulator. This platform is ideal for corporations or broadcasters needing to distribute multiple channels of HD programing over coax networks for MATV or CATV systems. QAM modulation is used in many world cable TV systems, including north American and European systems. Thor QAM-IP systems support both DVB-C and north American cable (ITU-T J.83B). The most common application for this system is to add additional channels of HD content to existing MATV or CATV channel lineups or for local generation of full HD cable TV feeds. The output of each modulator can be combined with existing cable or with the outputs from other modulators to populate the entire RF broadband spectrum. Depending on firmware, a QAM-IP or QAM-IPLL chassis will output adjacent QAM carriers with up to 38Mbps of bandwidth each. The additional bandwidth space can be populated with externally generated programing via an ASI input terminal. The ASI input can accept MPTS programing at up to 120Mbps of bandwidth for distribution.
