QMOD-HDSC
Overview
CR QMOD™ technology is opening the door to new HDTV applications. Create your own on-site HDTV
broadband distribution system using a variety of HD, SD, and AV sources with the Contemporary Research
QMOD-HD HDTV Modulator. No matrix routers or IP resources required, just tune in with standard displays
or CR HDTV tuners.
Compact and easy to integrate, the QMOD-HDSC features an internal, in-stream HD scaler for digital signage
applications. PC video fed through the RGBHV (or Component) input is automatically scaled to either 1080i
or 720p output settings. In addition, the video can be zoomed in and out and positioned so that signage can
be presented edge-to-edge when tuned by displays. An RGB Out HD-15 connector allows monitoring of
incoming VGA.
The QMOD-HDSC also accepts Component, S-Video, and Composite video and stereo, and coax/optical
digital audio. GPI inputs can trigger EAS broadcasts fed to the Composite input and assigned audio input.
Features
Super-easy scaling for VGA or Component input up to 1920x 1080 (see resolution list in
Specifications), Auto-scales by resolution, format in few simple steps:
Horizontal - Up/down arrows zoom and shrink, left/right move image on horizontal axis
Vertical - Up/Down rows move image up and down, Left/Right zooms and shrinks vertically
Clock Phase – adjust scanning to optimize image
QMOD-HDSC automatically saves formatting for each resolution (different refresh rates are
saved as unique presets)
Provides EDID data to support Apple and Windows 7 high-resolution connections (with upcoming
firmware update)
Employs pro-grade HD encoding that minimizes artifacts for motion video and signage “tickers”
Merges audio with video from analog stereo, digital optical and coax inputs
Creates an HD 720p/1080i or SD 480p/480i MPEG-2 stream with MPEG1 stereo audio for broadcast
Delivers a fully agile QAM 64/256 digital cable channel 2-135
Presently, the composite video input is not operational
