Thor » RF QAM Modulators, CH Insertors » HD-SDI Video over Coax Modulator
The H-HDSDI-QAM HD-SDI or SD-SDI to QAM agile modulator is used for the insertion of a standard HD-SDI or SD-SDI signal onto a QAM channel for distribution of video over coax. Our units feature modulation standards for any country in the world, including ATSC (8VSB), DVB-T/H, ISDB-T/H, and DVB-C. The unit fuctions as a QAM inserter. The modulator can be programed for any digital cable channel (2-135) and can be easily viewed by any digital cable ready HDTV or tuner. The H-HDSID-QAM unit offers adjustable amplification of up to 29 dBmV for distribution over an on site broadband cable system. Featuring MPEG-2 true HD encoding at resolutions up to 1080i, the H-HDSDI-QAM modulator is perfect for digital signal distribution at sports and entertainment facilities, retail and corporate offices, colleges, schools, and worship centers. The H-HDSDI-QAM modulator is ideal for any HDTV broadband signal distribution system.
