TranSwitch to Demonstrate the Industry's Most Advanced IP Core Solutions for High Definition Video at 2011 International CES

TranSwitch will be Showcasing its patented HDP™ core at Las Vegas Hilton Suite 336 at the 2011 International CES in Las Vegas, from January 6th to 9th, 2011

Shelton, CT – January 5, 2011 – TranSwitch® Corporation, Inc. (Nasdaq: TXCC) today announced that it will be showcasing its patented HDP™ technology, the industry’s most advanced High Definition Multimedia Interface™ (HDMI™) and DisplayPort™ integrated solution, at CES International 2011 with live demonstrations of HD-PXL 1.4, the Company’s latest intellectual property (IP) core. HDP™ is a cutting-edge technology developed by TranSwitch for High Definition Television (HDTV) and 3-Dimensional Television (3D-TV). It combines both HDMI™ HDMI™ 1.4 and DisplayPort™ in one single physical layer (PHY) enabling HDTV and 3D-TV manufacturers to support either standard with a single connector.

Conceived from TranSwitch’s HDP™ technology, the HD-PXL 1.4 HD-PXL 1.4 IP core, with bandwidth over 10Gbps, has been developed to meet all HDMI™ 1.4 resolution requirements including 1080p at 60Hz, the highest resolution for 3D televisions, and 4K x 2K, the resolution required for digital theatres. In addition, this IP core supports Ethernet over HDMI™ (HEC), and includes the audio return channel (ARC), which eliminates the need for separate audio cables between televisions and home entertainment systems. The result is a technology that elevates the home entertainment experience to new levels of picture quality for consumers while simplifying the overall manufacturing process for HDTV and 3D-TV manufacturers.

According to In-Stat :

• By 2013, one in five new TVs sold in the US will be 3D.
• Year-over-year shipment growth will be 231% between 2010 and 2011, resulting in a doubling of the US installed base of units for 3DTVs from 2010 to 2011.

“Visitors to CES 2011 will be very excited to see firsthand the driving role played by TranSwitch in delivering the very highest standards in 3D television viewing,” reports Amir Bar-Niv, Vice President for Systems and Applications at TranSwitch Corporation. “The ‘3D’ buzz created by movie studios has found its way into the home entertainment marketplace and our HD-PXL 1.4 core will play a significant role in helping OEMs to realize the full potential of 3D television viewing experiences, while also pushing the boundaries of video gaming to a whole new experiential level.”

“In addition, our HDP™ technology continues to be successfully adopted by major semiconductor companies requiring a solution that provides an interface for both consumer electronic HDMI™ products such as 3-D TV and PCs (which use DisplayPort™ connections). Unlike anything else in the marketplace today, HDP™ is a highly innovative, technological breakthrough that empowers OEMs to deliver an easy-to-use, extremely high performance bridge between multiple consumer electronics product segments.”
