Actiontec and Entropic Communications Partner to Deliver Superior Video Network
Performance to IPTV Homes

SAN DIEGO, Aug. 5, 2008 (PRIME NEWSWIRE) -- Entropic Communications, Inc.
(Nasdaq:ENTR), a leading provider of silicon solutions to enable connected home
entertainment, and Actiontec Electronics, Inc. a leading developer of broadband
connectivity and broadband-powered solutions, announced that the two companies
have extended their partnership to deliver high performance, next generation
customer premises equipment (CPE) for High-Speed Fiber network installations.

As one of Entropic's largest customers, Actiontec has been shipping MoCA-enabled
devices incorporating Entropic's technology for over two years and has worked
closely with Entropic to advance MoCA innovation and performance. Now, Actiontec
has incorporated Entropic's MoCA 1.1 compliant coaxial network controller into
its next generation wireless broadband router to enable superior network
delivery of HD video.

Actiontec has successfully married its technology with Entropic's MoCA compliant
chipsets to enable a robust digital entertainment network delivering multiple
streams of HD video throughout the home utilizing the existing coax cable
infrastructure. Actiontec's latest wireless broadband home router (Model #
MI-424WR) incorporates Entropic's newest coaxial network controller (c.LINK
EN2210) to deliver all the new features of MoCA 1.1, including high speed (175
Mbps), parameterized quality of service (PQoS), 16-node support, remote
diagnostic capability and the intrinsic security of a shielded, wired connection
combined with state of the art packet-level encryption. These important new
features address the needs of service providers and are designed to easily and
cost-effectively distribute multiple streams of HD quality entertainment
throughout the connected home of today and tomorrow.

Setting a New Industry Standard for Performance

Actiontec maintains its leadership in home gateways with the new MI-424 WR which
features advanced hardware design and superior performance. As a result, service
providers can increase service speeds beyond 100 Mbps and better meet the needs
of an increasingly sophisticated consumer base by rolling out multiple
value-added, bandwidth-intensive applications, such as parental controls, online
gaming, music, live sports, children's entertainment, movies and television
programming.

"We are delighted to continue our successful collaboration with Actiontec to
provide consumers with the best MoCA-compliant technology," said John Graham,
Vice President of Marketing at Entropic. "The new features of our MoCA
1.1-compliant chipset, along with Actiontec's leading broadband connectivity
solutions, are delivering the advanced network performance for the evolving
connected home."

Easily Share Digital Entertainment

The EN2210 Coaxial Network Controller is the newest addition to Entropic's
c.LINK(tm) family dedicated to allowing a complete coaxial networking solution
for the distribution of multiple high definition and standard definition video,
digital, voice and broadband data. The EN2210 combines increased host interface
flexibility with reduced power consumption and lower system integration costs.
Working together with the EN1010 Coaxial Network Interface, the chipset operates
at radio frequencies from 800 to 1500 MHz, enabling compliance to the MoCA
specification. Based on Entropic's c.LINK protocol, the core technology chosen
by MoCA, the EN2210 enables secure and robust communication using existing home
coaxial cables without the need for new wiring or modifications.

"Actiontec has a long history of working closely with Entropic to bring MoCA
solutions to market. Actiontec products will continue to push performance
boundaries by using leading MoCA technology from Entropic Communications," said
Brian Henrichs, Vice President of Business Development at Actiontec Electronics,
Inc.
