Briefly: I think UDI means you would
be able to use your phone in a video-
conference link, even though the phone
itself only served as a conduit to
something else that actually displayed
the video.
I know next to nothing about Bluetooth,
but most packet protocols need some
kind of adaptation to the requirements
of multimedia.

Subject: (keitai-l) UDI and Bluetooth ??
> Hello,
> I read this article in the Nikkei Electronics :
>
> "at the Bluetooth Congress, held in June in Monte

> reported progress on formulating a Bluetooth

> Co., Ltd., Matsushita Communication Industrial Co.,
> Ltd. and Nokia Corp. of Finland. The specification has
> nearly reached the "Version 0.5" stage, when it will

> UDI is a specification for implementing the bearer
> services defined in recommendation I.230 of the
> Telecommunication Standardization Sector of the
> International Telecommunications Union (ITU-T).
> Normally, a terminal adapter is required to implement

> finalized by June 2002"
