Presentation of Our Research Results at Broadcasting
NHK Science & Technical
This year's annual open
house of our laboratories
will be held jointly with
the BS Digital Fair at
the Broadcasting Center
in Shibuya. Here I will
introduce selected items
from the main exhibitions.
Studio 501 will feature
a provisional "future
living room." This exhibition
will highlight the various
influences and changes
that television will bring
about in peoples' lives.
The home server that we
are developing as a new
home program storage device
for the digital era offers
numerous new and convenient
TV viewing styles.
In Studios 506 and 505,
we will present "human-friendly
and "fascinating program
technology" based on the
theme of "How broadcasters
will change." Studies
on "human-friendly broadcasting
technology" are underway
for providing broadcasting
services. One product
of this research is a
broadcast news transcription
system that automatically
recognizes a studio announcer's
speech and instantly creates
subtitles in proper Japanese
using Kanji and Kana.
The "fascinating program
technology" section will
offer a glimpse of efficient
program production technology
that makes optimum use
of computer technology.
These exhibitions include
new virtual studio and
Exhibited in the 3rd floor
and Tent 2000 will be
the latest broadcasting
technology developed by
NHK. The exhibition will
contain a 3-D television
for future broadcasting
services and a multi-beam
receiving flat antenna
for satellite broadcasting.
These colorful research items will be exhibited
to plainly introduce our viewers to the coming
digital satellite broadcasting systems.
Please look forward to the event and visit
