QuickMedia Transport System

Using a new, proprietary signal routing solution, signals such as composite
video, S-video, RGBHV, audios, and microphone, are all transported using a
single cable solution called QuickMedia (QM).
The QM transport system port is capable of managing computer, video, and
audio signals simultaneously through one CAT5E or CAT6 UTP (unshielded
twisted pair) wire, simplifying installations.
Routing CAT5E or CAT6 UTP cable is less expensive and much simpler than
routing multi-colored, multi-conductor coax cable. All Crestron products using
the QM transport system are capable of sending and receiving QM signals via
standard CAT5E or CAT6 cable. Installation of any QM device is as simple as
installing one set of QM wires from output to input. Installations are flexible,
affordable, and fast.
The Crestron QuickMedia cable "CRESCAT-QM" contains one CAT5E cable
®
and one Cresnet cable in siamese jackets.
NOTE: Do not untwist the two wires in a single pair for more than 1/3-1/2"
(0.84 – 1.27 cm) when making a connection. The twists are critical to canceling
out interference between the wires.
CRESCAT-QM Cable
The QuickMedia transport mechanism performs delay compensation on each
video input to compensate for signal skew, and frequency/bandwidth
