Contemporary Research 3 QMOD-SDI
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-SDI 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-SDI accepts SDI, Component, or S-Video/Composite NTSC, 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-SDI opens the door to cost-effective distribution of HD-SDI broadcast sources and live video, digital
signage, HD subscriber sources, and EAS emergency AV, 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-SDI setup, with options for 2-way integration with custom control systems.
