The H-YPbPr-QAM is a QAM agile modulator used for the insertion of a standard HD Composite or VGA signal onto a QAM channel for distribution of video over coax. 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-YPbPr-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-YPbPr-QAM modulator is perfect for digital signal distribution at sports and entertainment facilities, retail and corporate offices, colleges, schools, and worship centers. The H-YPbPr-QAM modulator is ideal for any HDTV broadband signal distribution system.
