Japanese history of Television Set
"On 25 December 1926,
Kenjiro Takayanagi demonstrated a television system with a 40-line
resolution that employed a Nipkow disk scanner and CRT display at
Hamamatsu Industrial High School in Japan. This prototype is still on
display at the Takayanagi Memorial Museum in Shizuoka University,
Hamamatsu Campus. His research in creating a production model was
halted by the SCAP after World War II....A digital TV service was
proposed in 1986 by Nippon Telegraph and Telephone (NTT) and the
Ministry of Posts and Telecommunication (MPT) in Japan, where there
were plans to develop an "Integrated Network System" service. However,
it was not possible to practically implement such a digital TV service
until the adoption of DCT video compression technology made it possible
in the early 1990s.[141] In the mid-1980s, as Japanese consumer
electronics firms forged ahead with the development of HDTV technology,
the MUSE analog format proposed by NHK, a Japanese company, was seen as
a pacesetter that threatened to eclipse U.S. electronics companies'
technologies. Until June 1990, the Japanese MUSE standard, based on an
analog system, was the front-runner among the more than 23 different
technical concepts under consideration. Then, an American company,
General Instrument, demonstrated the feasibility of a digital
television signal. This breakthrough was of such significance that the
FCC was persuaded to delay its decision on an ATV standard until a
digitally based standard could be developed."-Television by Wiki.
