CR QMOD™ technology is opening the door to new HDTV applications. The QMOD-HD HDTV Modulator enables cost-effective distribution of HD digital signage and HD subscriber sources using existing broadband coax cabling in sports, retail and entertainment facilities, corporate offices, colleges, schools and worship centers.

• Create your own on-site HDTV broadband distribution system using a variety HD, SD, and AV sources
• Distribute digital signage, satellite, cable, and media as HD digital cable channels over existing broadband wiring
• View HD sources at any destination using HDTV displays or tuners

• Accepts 720p/1080i/480p/480i VGA, Component, or S-Video/Composite video, auto-syncs to input resolution
• Employs pro-grade HD encoding by NTT that minimizes artifacts for motion video and signage “tickers”
• Merges audio with video from analog stereo, digital optical and coax inputs
• Creates a high-definition 720p/1080i MPEG-2 stream for broadcast
• Delivers a fully agile QAM 64/256 digital cable channel 2-135
• Amplifies for distribution over an on-site broadband cable system with adjustable output level to 29 dBmV, compatible with all cable format broadband systems
• Sets up with front-panel buttons and easy to use menus, including inputs, encoding, channel, and RF options.
• New! Create single-part virtual channels, such as 116, 645 to match Guide channels
• Integrates with RS-232 control and feedback with simple ASCII commands
• Saves power and rack space using efficient design, fan-free cooling, and compact enclosure
• Powers up in less than 4 seconds, no OS overhead
• Meets RoHS safety and California energy standards.
