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 

 

Amplifies for distribution over an on-site broadband cable system with adjustable output level,  
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 

 

Saves power and rack space using efficient design, fan-free cooling, and compact enclosure 

 

Includes compact switching power supply 

 

Mounts in optional 1RU single (RK1) or dual (RK2) 19” rack kits 

 

Meets RoHS safety and California energy standards 

 

New 

– Inputs 1280x800 video PC, 480i via Component
