CopperGate Demonstrates New HomePlug AV and HomePNA Chipsets at CES

MILPITAS, CA–(Marketwire – January 5, 2010) – CopperGate, a wholly-owned subsidiary of Sigma
Designs (NASDAQ: SIGM), a leading provider of system-on-chip (SoC)
solutions used to deliver entertainment and control throughout the home and
the first semiconductor company to support multiple home networking
standards (HomePNA for coax and phoneline, and HomePlug AV for powerline),
announced it will demonstrate its HomePNA and HomePlug AV solutions at the
Consumer Electronics Show (CES),
January 7 – 10, 2010 in Las Vegas, Nevada.

Members of the press and analyst community are invited to visit the Sigma
Designs meeting room 36153 South Hall 4, where CopperGate will demonstrate
for the first time its ultra-green HomePlug AV CG2110 Chipset, announced
last October. The chipset offers service providers and CPE equipment
manufacturers a cost-effective, reliable, and easy way to distribute
demanding video, audio, data, and voice, such as triple-play services and
IPTV, over powerlines throughout a home. At CES, CopperGate will be
demonstrating the HomePlug AV CG2110 Chipset’s superior features versus
existing solutions.

The company will also showcase its market-leading HomePNA
chipsets, which enable service providers to deliver IPTV and broadband
access to MDU more affordably.

Executive Quotes:

Gabi Hilevitz, CEO CopperGate

“The HomePNA standard continues to provide the highest performance and
lowest costs for delivering in-home networking and broadband access,
helping service providers reduce IPTV installation costs by over $300
million to date.

“HomePNA is an excellent broadband-access technology for emerging markets.
It eliminates costly upgrades and enables small to medium-sized MSOs to
deliver triple-play services using the existing cable coax infrastructure
by adding two-way broadband distribution with minimal investment.

“CopperGate can deliver digital broadcast content over every wire inside
the home, including coax, phone lines and powerline. The HomePlug AV CG2110
chipset we’re showing at CES will demonstrate our ability to outperform
other competing solutions.”
