News Europe : ST Microelectronics announced the world's first single-chip
Set-top Box (STB) solution supporting the High Definition H.264/AVC
and VC1 specifications, which are poised to enable the next generation
of high quality consumer video systems and broadcast services. ST
is the world's leading supplier of ICs for set-top boxes*, and the
introduction of the new STB7100 allows manufacturers to in-troduce
products that will enable this market.
The
extraordinary level of integration of the new device - which combines
all the STB func-tions and multi-standard decoding circuitry into
a single chip, rather than being an add-on processor for an existing
product - coupled with its production using ST's state-of-the-art
90nm process technology, results in the most cost-efficient solution
and minimizes both de-sign and production costs for STB makers.
Both
VC1 - Microsoft's Windows Media 9 Series codec - and the H.264/AVC
(Advanced Video Coding) standard, also known as MPEG-4 Part 10,
are ultra-efficient, fully scalable video technologies that produces
high quality video at lower data rates than current solutions for
everything from HDTV and DVD to 3G (third generation) mobile phones.
Services broad-cast using H.264 use considerably less bandwidth
than the currently widely used MPEG-2 coding scheme, and at a much
lower bitrate, allowing broadcasters to economically transmit more
high definition programming. Compression efficiency is improved
by more than 50%.
The
latest advanced codec technologies for DVD-Audio and DVD security
encryption are embedded in the new decoder, and the use of a powerful
ST40 CPU makes the STB7100 the ideal platform for Car Multimedia
Centers able to directly drive - as a Master device - appli-cations
such as GPS, at the same time as handling DVD and audio.
"By
creating our STB7100 H.264 solution as a single chip in 90nm technology
instead of tak-ing the simpler co-processor path, ST is providing
manufacturers with by far the most cost-effective base for their
products in this market," said Christos Lagomichos, General
Manager of ST's Set-Top Box Division. "The demand for new H.264
and VC1 video codec chips is in-credible, and the availability of
the STB7100 means that consumers will soon have HDTV boxes, IP-TV
and DVDs that use the latest standard, and broadcasters will be
encouraged to further develop their services. And this is the ideal
platform for the HD-DVD and Blue-Ray DVD technologies."
The
STB7100 can simultaneously decode multiple HD streams and output
the resultant video to two television sets, or display picture-in-picture.
Its CPU core is a high-performance 300MHz ST40, ST's 32-bit RISC
family based on the SuperH™ architecture and widely used across
digital consumer applications. It supports all of the current STB
operating systems and middleware, with power to spare for software
enhancements in the future.
The
new device is based on an innovative video decoding architecture
which combines hard-ware and software techniques to allow systems
to be upgraded in the field to support new standards as they become
available. For Digital Video Recorder (DVR) applications it fea-tures
embedded peripheral interfaces - including serial, ATA and USB 2.0
- to allow external devices to be added easily to an STB or DVD
player, either during manufacture or by the viewer, in order to
provide additional functionality. Viewers increasingly use digital
video re-cording for program time shifting. Other peripherals that
could be connected to a set-top box through the USB interface include
digital cameras, printers, and memory cards.
The
latest advanced codec technologies for DVD-Audio and DVD security
encryption are also embedded in the new decoder, and the use of
the powerful ST40 CPU makes the STB7100 the ideal platform for Car
Multimedia Centers able to directly drive - as Master de-vice -
applications such as GPS, at same time as handling DVD and audio.
It is a true multi-ple application chip.
The
STB7100 is available now in sample quantities in a 35 x 35 PBGA
package and costs $29 when purchased in large volumes. Volume production
is planned for early 2005.
