Tut Systems, Inc., an industry leader enabling the delivery of next-generation data and video services over broadband networks, today announced that it will showcase its MPEG-4 Advanced Video Codec High Definition (AVC HD) compression at the Telecommunications Industry Association's (TIA) GLOBALCOMM(TM) 2006 convention at McCormick Place in Chicago, IL on June 5-7 (Booth #77048). The company believes that its MPEG-4 AVC HD transcoding solution will be a first in the IPTV industry.

MPEG-4 AVC HD compression is critical for IPTV service providers seeking to deliver pristine quality High Definition Television (HDTV) over copper access networks. While today's MPEG-2 HDTV is compressed to approximately 19 Mbps, service providers will see bandwidths below 10 Mbps with MPEG-4 AVC HD transcoding in Tut Systems' carrier-class Astria content processor (CP) product line. This is a critical threshold for ensuring that IPTV service providers can deliver HDTV over advanced DSL networks that are limited to bandwidths below 15 Mbps.

By implementing unique transcoding functionality in the world's most deployed IPTV headend solution, the Astria CP improves quality and reduces the amount of equipment required to deliver MPEG-4 AVC HD content in a field-tested, reliable platform. The Astria CP's MPEG-4 AVC HD transcoding capability will be available for initial customer delivery at the end of the second quarter of 2006.

"At Cavalier Telephone, we view HDTV as a critical element of our Broadband TV video package," said Brad Evans the company's CEO. "With Tut Systems' MPEG-4 AVC compression technology, Cavalier will deliver the high definition image quality that our customers are expecting."

"Service providers around the world are seeing increased consumer demand for innovative service offerings like high definition television and our a MPEG-4 AVC transcoding solutions will make such services a reality for companies like Cavalier Telephone that are looking to deliver HDTV over copper networks," said Sal D'Auria, Chairman, President and CEO of Tut Systems. "Our continued success in the IPTV market will only accelerate as we deliver our MPEG-4 AVC HD transcoding product to IPTV service providers in 2006."

In addition, Tut Systems' booth at GLOBALCOMM will highlight:

• The latest in MPEG-4 AVC standard definition compression technology including encoding and transcoding from MPEG-2;
• IP forward error correction for the delivery of flawless video over IP networks;
• The highly scalable Astria VSP which will showcase digital simulcast applications for the conversion of IP video to digital and analog RF for delivery over FTTx and coaxial cable networks.
