Contemporary Research 3 QMOD-HD
Overview
CR QMOD™ technology is opening the door to new HDTV applications. Create your own on-site HDTV broadband distribution system
using a variety 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-HD accepts HD RGBHV or Component video, or SD S-Video/Composite NTSC, as well as
stereo and digital PCM audio, converts the audio and video to a digital cable channel, and amplifies for distribution through broadband
cable system. Innovative in design and value, the QMOD-HD opens the door to cost-effective distribution of digital signage and HD
subscriber sources using existing broadband coax cabling in sports, retail and entertainment facilities, corporate offices, colleges,
schools and worship centers. Front-panel buttons and text menu display simplify QMOD-HD setup, with options for 2-way integration
with custom control systems. GPI inputs can switch to AV inputs for EAS broadcasts.
Features
 Accepts RGBHV, Component, or S-Video/Composite NTSC, 720p/1080i/480/480i formats
 Presents 480p/480i video as full-screen image
 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
 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
 Allows creation of two-part (XX-XX) and single-part (XXX –emulates Guide channel ID) virtual channels
 Allows use of locking BNC-HD15 or HD15-HD15 cables to connect YPbPr video via the RGB input
 Responds to GPI inputs to switch to EAS composite video and audio
 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 – Auto-sync for input resolution, no need to set output resolution
 New – Free option to drive 2-4 QMOD Modulators from a 12 VDC 4A power supply.
Integration
 Connect one source to VGA, Component, or S-Video/Composite inputs
 Use the QMOD-HDSC for VGA sources – computers do not output video-standard 720p/1080i signals
 Connect audio to digital optical, coax, or stereo audio inputs
 Select inputs, channel, resolution, and RF output parameters from front-panel menus
