Entropic's Channel Stacking Switch Provides Enhanced Direct-
    to-Home Entertainment Services to More Brazilian Households

SAN DIEGO, March 12, 2012 (GLOBE NEWSWIRE) -- Entropic Communications,
Inc. (Nasdaq:ENTR), a leading provider of silicon and software
solutions to enable connected home entertainment, and Prime Electronics
& Satellitics Inc., a leading manufacturer of advanced digital
satellite communication and wireless consumer electronic products,
today announced that one of the largest telecommunications carriers in
Brazil will deliver Direct-Broadcast Satellite (DBS) entertainment
services to single family homes (SFH) via Entropic's Channel Stacking
Switch (CSS) single cable wire infrastructure.

According to a recent report from Digital TV Research, by 2016, the
Brazilian Direct-to-Home (DTH) pay-TV market is expected to reach 11.8
million households, yielding an 18.8 percent penetration rate; doubling
today's total. By adopting Entropic's CSS technology, DBS service
providers can capitalize on these growth expectations - offering better
service to its SFH customers. Additionally with CSS technology, DBS
service providers can support multiple tuners over a single cable -
enabling multi-tuner set-top boxes (STB), such as digital video
recording (DVR) devices, to deliver high definition (HD) services to
multiple rooms in the home, allowing easy plug-and-play STB
installations, simplifying upgrades and new installations at a lower
cost¾all with improved aesthetics for the homeowner.

"This technology collaboration with Entropic provides our Brazilian
pay-TV service provider a solution to offer its single-family customer
base a cost-effective transition to advanced TV and entertainment
services," said Vincent Hung, vice president, Sales and Marketing,
Prime Electronics & Satellitics. "We have worked closely with the
Entropic development team to design and implement a robust single cable
DBS system which is currently being successfully deployed to Brazilian
multiple dwelling units (MDU) customers. We are confident this approach
will meet all end-user entertainment experience requirements for SFH
customers, quickly and without the need to add any new costs or
wiring."

Entropic has changed the paradigm of DBS installations with its CSS
technology. Designed to significantly reduce both the cost and
complexity of SFH satellite deployments, Entropic's CSS technology
leverages its RF5219 chip into a low noise block (LNB) product, which
alleviates the need for multiple new cables to be brought into the home
when more than a single tuner STB is installed. In this new build-out
model, DBS service providers can provide access to available
programming for up to four tuners within a single cable run from the
satellite dish -- keeping installation costs at a minimum and in many
cases, enabling DBS service where it would otherwise be impossible to
deliver.

"We're excited about this latest deployment of our CSS technology as
Prime Electronics & Satellitics and its service provider customers
continue to differentiate their technology offerings and expand their
reach from multi-dwelling units into single family homes," said Patrick
Henry, president and chief executive officer, Entropic. "As Brazilian
viewing habits migrate from a single location to multiple screens per
home and as consumers begin to adopt time shifting services such as
DVRs, our technology will be a key enabler for this transition by
providing flexibility and increased user video bandwidth."

Additionally, by deploying Entropic's proven CSS solution, customers
have the unique opportunity to receive additional new home networking
services based on Entropic's leading MoCA(R) (Multimedia over Coax)
silicon and software solutions, which provide the ability to reliably
distribute multiple streams of HD content -- from video, audio and data
traffic -- throughout the home.
