CR QMOD™ technology is opening the door to new HDTV applications. The QMOD-HDSC HDTV Scaler Modulator is the first HD modulator specifically designed for digital signage integration. The onboard in-stream scaler ingests signage at PC resolution, converting the output to 1080i or 720p video. In addition the scaler features up and down-scaling, zoom, shrink, and positioning.

• 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

The QMOD-HDSC features super-easy scaling for VGA or Component input up to 1920x 1080 (see resolution list in Specifications), Auto-scales by resolution, format in two simple steps:

• Horizontal - Up/down arrows zoom and shrink, left/right move image on horizontal axis
• Vertical - Left/Right rows move image up and down, Up/Down zooms and shrinks vertically

• Clock Phase adjusts scanning to optimize image
• QMOD-HDSC automatically saves formatting for each resolution and refresh rate
• Converts PAL video to NTSC
• NTSC composite video not presently operational
• 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
• Responds to GPI inputs to switch to EAS composite video and audio
• 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.
• Integrates with RS-232 control and feedback with simple ASCII commands
• Powers up in less than 4 seconds, no OS overhead
• Saves power and rack space using efficient design, fan-free cooling, and compact enclosure
• Meets RoHS safety and California energy standards.
