SIRIUS Conducts First-Ever Live Broadcast of Video Over Satellite Radio System

SIRIUS ,
the only satellite radio service delivering uncompromised coast-to-coast music
and entertainment for your car and home, today demonstrated a live video
broadcast over its satellite radio system, becoming the first satellite radio
company to demonstrate video capability. The demonstration of this new video
transmission capability took place at the Consumer Electronics Show (CES) in
Las Vegas.

At its press conference today at CES, SIRIUS demonstrated a unique
application of its satellite technology that could enable its subscribers to
receive video transmissions, in addition to the company’s offering of music,
news, sports and entertainment. Today’s consumer options for in-vehicle video
are limited to built in VCRs or DVD players.

Currently, SIRIUS utilizes its satellite broadcast technology to transmit
100 digital “streams” of entertainment that include 60 streams of 100%
commercial-free music, and 40 streams of news, sports and entertainment for
$12.95 per month. Unlike today’s radio channels, these digital streams from
SIRIUS can also carry video signals or other data.

“It’s all about choice,” said Joseph P. Clayton, President and CEO of
SIRIUS. “Our technology enables us to transmit a wide variety of data in
addition to our commercial-free music and entertainment programming. But,
regardless of what we transmit, the emphasis is on variety of selection and
quality programming that enhances people’s lives. Ultimately, our mission is
to provide customers with premier entertainment choices.”

“SIRIUS is the only satellite radio company that features statistical
multiplexing technology, which allows us to maximize the utilization of our
bits,” said Larry Pesce, Vice President of Product Management and Strategic
Planning. “This technology not only lets us dynamically allocate bandwidth to
where the music needs it, but also gives us the flexibility to use those bits
to transmit other data, which could include stock quotes, news clips, kid
shows, sporting events, movies, along with many other types of content and
applications.”
