of standard TSOP packages and offer
much-improved mountability. The pack-
age meets needs for higher density ICs
offering larger capacities, and are a perfect
response to burgeoning demand for
smaller portable products with higher
performance.
REAL-TIME 3D IMAGE RECOGNITION
AND PROCESSING
Real-time recognition and display of 3D
images on PCs became a reality in July
1998. The company’s new technology can
accurately distinguish moving objects
from their background, including the
human body or a pair of hands. It opens
the way to gesture-based interfacing with
PCs, an approach enjoying advantages of
greater simplicity and higher speeds than
the voice or other methods. Ease-of-use
and flexibility promise a high-potential
alternative to the keyboard or mouse for
input to PCs. Toshiba is investigating this
with a prototype motion processor.
CO2-ABSORBING CERAMIC CAN CUT
EMISSIONS
Reducing emissions of carbon dioxide
(CO2) is a cornerstone of efforts for envi-
ronmental protection. In April 1998,
Toshiba developed a ceramic material
able to absorb 400 times its own cubic
volume of CO2—more than ten times
that of any previous material. And as it
does so at temperatures between 450-
700°C, the ceramic is ideal for the high
temperature environments of thermal
power plants and automobiles, the main
source of CO2 emissions. Subsequent
development of a second ceramic material
with similar characteristics confirms that
Toshiba is on the way to a promising
solution to a pressing problem.
MOBILE MOTION™—MPEG-4 VIDEO
STREAMING SYSTEM
Toshiba has developed Mobile Motion™,
the world’s first MPEG-4 video streaming
system. MPEG-4 is a next-generation
video signal compression standard that
was approved in February 1999 by the In-
ternational Organization for Standardiza-
tion (ISO). MPEG-4 is highly resistant to
errors and incorporates media object-
based coding. Mobile Motion™ was cre-
ated specifically to prevent signal
degradation when sending video trans-
missions over the Internet and other low-
bit-rate networks. A pre-filter eliminates
the noise that is a byproduct of all MPEG
compression and a post-filter raises the
compression rate. Furthermore, a propri-
etary rate control mechanism ensures uni-
form intervals between frames to
maintain smooth motion during playback.
