Plaque citation summarizing the achievement and its significance:
Here at KDDI, the world's first all-digital, high-resolution TV standards convertor was commercialized. By making prompt use of semiconductor memory, the equipment has been downsized and stabilized for easy operation, while adaptive image processing has minimized resolution degradation and improved transmitted picture quality.
200-250 word abstract describing the significance of the technical achievement being proposed, the person(s) involved, historical context, humanitarian and social impact, as well as any possible controversies the advocate might need to review.
Since TV standards conversion is mandatory in transmission between countries that use different TV standards, its development can be said to be the history of international TV transmission itself. It has contributed greatly to interconnecting people around the world by providing live coverage of international sporting events as well as major news broadcasts. In the proposed milestone (commercialization of digital TV standards convertor), KDDI has succeeded in digitalizing the previously analog TV standards conversion, and has also succeeded in significantly reducing the resolution degradation caused by the conversion. In other words, by going from analog to digital, the number of simultaneous relays was increased due to the space savings resulting from the drastic downsizing, making international TV transmission closer to the people. In addition, the advanced signal processing has dramatically improved the picture quality, whereas in the past, we had no choice but to accept large picture quality degradation such as blurriness. Furthermore, this digitalization has laid the foundation for applying sophisticated image processing technology which has developed rapidly since then, leading to further evolution of TV standards conversion such as the introduction of motion compensated frame rate conversion, so that now international TV programs can be enjoyed with picture quality almost as good as that of local programs.

KDDI Corporation, Garden Air Tower, 3-10-10, Iidabashi, Chiyoda-ku, Tokyo, 102-8460 JAPAN (coordinates: 35.700463, 139.750537)
Describe briefly the intended site(s) of the milestone plaque(s). The intended site(s) must have a direct connection with the achievement (e.g. where developed, invented, tested, demonstrated, installed, or operated, etc.). A museum where a device or example of the technology is displayed, or the university where the inventor studied, are not, in themselves, sufficient connection for a milestone plaque.
Please give the address(es) of the plaque site(s) (GPS coordinates if you have them). Also please give the details of the mounting, i.e. on the outside of the building, in the ground floor entrance hall, on a plinth on the grounds, etc. If visitors to the plaque site will need to go through security, or make an appointment, please give the contact information visitors will need. Corporate building
Are the original buildings extant?
Yes
Details of the plaque mounting:
At the exhibition space in the reception floor (28th floor).
How is the site protected/secured, and in what ways is it accessible to the public?
The plaque is publicly accessible. The plaque site is within KDDI Headquarter, and is under the proper security control. The visitors can access with prior appointment to KDDI.
Who is the present owner of the site(s)?
KDDI Corporation
