New Gefen Extender Sends HD Video Over CAT-5 Cable

WOODLAND HILLS, CA – April 27, 2004 – A revolutionary new method of high
definition video extension from Gefen transmits audio and video data up to
150-feet over CAT-5 cable. Never before could CAT-5 cables carry the large
amounts of data required for HD clarity and precision. But new chip
technologies combined with skillful engineering has created a method of
packaging data that can be transmitted successfully using industry-standard
CAT-5E cables.

Multiple resolutions up to 1080i and multi-channel digital audio are
effective at distances up to 150-feet, making the HDTV Extender over CAT-5
cable an economical alternative to fiber optics or copper cables for medium
length installations. It is highly advantageous when upgrading audio/video
systems from analog to digital because cabling does not have to be replaced.

THe HDTV Extender is available in two models that work with HD’s two most
popular interfaces: DVI (digital visual interface) and HDMI (high
definition multimedia interface). DVI, often the preferred format for
professional a/v applications, transmits high resolution, uncompressed
digital video data from source to display. HDMI, geared towards the
consumer market, transmits high resolution, uncompressed digital video and
multichannel digital audio from source to display. When used with
computer-based systems, DDC control signals are sent in addition to HDTV
video on their own dedicated CAT-5 cable.

The HDTV Extender is HDCP-compliant, retails for $499 and is available to

eight weeks. The HDTV Extender comes with its own sender and receiver
