Oki Electric Industry Co., Ltd. Annual Report 200212
Oki prioritizes speed in its R&D. To be a forerunner in providing
customers with solutions that are safe, reliable and optimized for
each individual, we accentuate R&D that integrates the most
advanced technologies.
Information Systems
Development of a Human Action Recognition Technology
Oki developed a human action recognition technology that identifies the person in images
being recorded by a video camera and instantly analyzes the person’s silhouette to track
his or her actions. By combining this with the MPEG-4 image distribution software we
developed, we created an efficient long-distance monitoring system that automatically
transmits high-quality moving pictures only when a noteworthy event has occurred.
Telecommunications Systems
Development of a Multimedia Communication Server
Oki developed and launched CenterStage™, a multimedia communication server for
carriers, to help telecommunications companies shifting to high-value-added business
overcome competition in telecommunications costs. We also developed call control func-
tions for session initiation protocol (SIP)—which contributed to the popularization of IP
telephone calls with signaling that resembles the Internet—and an application interface
that enables telecommunications companies to provide high-value-added services.
Development of OKI MediaServer V5.0
Oki is responding to rising expectations that such new image services as VOD and TV
phones over broadband networks can be developed with the OKI MediaServer V5.0, devel-
oped as a platform for these kinds of image services. As a highly functional image distribu-
tion platform aimed at large-scale commercial services, it has strong functions for distributed
VOD technology, MPEG-4 Advanced Simple Profile (ASP), copyright protection technology
and license management technology.
Electronic Devices
Mass LSI Production with Full-Depletion SOI Technology
Oki was the first company in the world to mass-produce LSI for watches using fully
depleted SOI as a commercial product; this product is already being shipped. This technol-
ogy reduces up to 75% of the power consumption of the LSI. By combining the fully
depleted SOI with solar batteries, it is now possible to develop a watch that does not
require battery replacement.
40 Gb/s EA-Integrated DFB-LD Module
Oki successfully developed a small, low-power-consumption 40 Gb/s EA-modulated laser
module. We expect this device will be used in 40 Gb/s applications, including metro WDM
systems with ranges from 2 km to hundreds of kilometers.
CenterStage™ is a large-scale
multimedia communication
server offering the most advanced
IP communications, such as
IP telephony services.
R&D HIGHLIGHTS
Oki’s human action recognition
technology is based on the
Company’s technologies for the
detection of motionless and slow-
moving vehicles for the Advanced
Cruise-Assist Highway System.
The new technology makes it
possible to recognize even the
movements of individuals that
are difficult to predict.
