Contemporary Research 2 QMOD-SDI1.5
Overview
Employing a totally new HD encoding technology, the QMOD-SDI1.5 continues the QMODTM track record for
quality and innovation, setting a new benchmark for features and performance. In addition to standard SDI
resolutions, the QMOD-SDI can accept 3G SDI and 60/30 Hz feeds from prosumer SDI sources. Users can
upgrade operation for full scaling and dual-channel operation by entering optional upgrade key codes.
Sources
One HD-SDI input, 3G 1080p and 1080i/720p 59.94/60 Hz HD-SDI, and
SD-SDI 480i widescreen/4:3 video; also accepts embedded 608/708 captioning and Dolby AC-3 and AES audio
One Component input, 1080i, 720p, 480p, 480i video
One Composite video input for encoding, captioning, or EAS use
Stereo, optical and coax audio inputs
Encoding
Output
Operation
Creates a high-definition 720p/1080i MPEG-2 stream for broadcast
Accepts pass-through AC-3 audio, converts stereo and PCM to stereo AC-3, can create dual-language audio for
each program
Includes captioning from Line 21 data on composite video inputs
Flex encoding downscales 1080p to 1080i, allows use of 720p/1080p 60Hz sources, and compensates for 60/30 Hz
sources such as consumer HD cameras
QSDI-Scale upgrade key allows full video up- and down-conversion
QSDI-Dual 2-channel upgrade key allows selection of inputs to create 2 HD channels
Delivers a fully agile QAM 64/256 digital cable channel 2-135
Up to 270 HD Programs/Channels per system
Streams IPTV from GigE Ethernet port
Distributes channel 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.
Onboard Web page for setup and monitoring, also accessible from front-panel USB port
Control with IP Telnet commands
Saves power and rack space using efficient design
Includes compact switching power supply
Mounts in optional 1RU single (RK1) or dual (RK2EZ) 19” rack kits
Meets RoHS safety and California energy standards

There are 3 ways you can change the settings:
Front Panel. Press the SETUP button use the Up/Down buttons to move through menus, Left/Right to
change settings, then press SELECT to store the changes at each step.
o Select a menu group (Quick, A, B, QMOD), then SELECT to view that group’s menus
o Press SETUP to move back to other menu groups
Ethernet. Access the onboard Web pages. Helpful for remote access when system is fully integrated
with site Ethernet.
USB-Web. Access Web pages from front-panel USB port, simplest solution for full setup, requires no IP
setup or connection, connect from the front of the equipment rack
Front Panel Menus
There are four groups of menus you can choose from:
Quick Setup supplies just the few steps needed to output the source as a channel.
Program A goes deeper in to all the options for the first source
Program B does the same for the second source, if that option is enabled
Common menus set the core values for the entire channel, such as IP address, level, cable plan, and
other options
Quick Setup Menus
This series is designed for a quick setup for testing and integration.
At this point, you should be able to view the QMOD channels on a test TV.
A QMOD Channel, or any QAM Channel. can include two video streams, called Programs. It’s really one stream
that contains both videos. The TV figures out which to play using the channel ID, typically something like
channel IDs 2.1 and 2.2, 3.1 and 3.2 and so on. For marketing purposes we use the popular term “2-Channel”
the general public understands, for integrators we use the more correct term “2 Programs”.
