The history of HDTV (High Definition Television)
For those of you unfamiliar with HDTV, is the highest resolution in the new DTV set of rules in combination with CD-quality Dolby Digital surround sound. This combination creates spectacular illustration with stunning audio effects, which HDTV is quickly moving to become the new standard in television systems.
HDTV looks like a completely new innovation but in fact the system has been around in various forms since the mid-1970s and has developed a pretty impressive history.
In the years 1970 and 1980, the product testing for HDTV has been developed in Japan as a way to improve the quality of television and therefore sell more TVs. The first system was called MUSE HDTV and used filtering tricks to reduce the original signal source to reduce the use of bandwidth.
The idea of introducing HDTV in the United States has been greeted with mixed reactions. In 1980, the National Association of Broadcasters in the United States invited NHK, the public network in Japan, to present the ideas behind the MUSE system to the Federal Communications Commission. At that time, there are two groups that were strongly against the introduction of HDTV in the U.S.
The first group that opposed the introduction of this new technology was the terrestrial television broadcasters. They were frightened by the possibility of being excluded from the HDTV market because HDTV required more bandwidth (the amount of information transmitted via a channel or connection) than standard TV. These broadcasters worried because the channels that have already had the license would not be able to handle the bandwidth of this new form of television.
The other group that is concerned about HDTV in the United States was the Congress. Congress felt threatened by the innovations that have seen many Japanese came to the U.S. and ultimately did not want to introduce a new form of communication that was owned by another country all together.
With these two complaints in mind, the U.S. government has tried to invent a new form of HDTV. Groups of researchers and producers have been grouped together to form different teams. Each team would try to create an HDTV system that would fit into existing channels that were used by broadcasters.
After years of work, teams of researchers and producers have decided to join forces. This unit has given birth to a new group known as the Grand Alliance.
The researchers continued their attempts to develop this new form of HDTV, they discovered that this new technology should be partly digital, so that all the information needed to adapt to existing channels. With this in mind, you were able to develop a system that was very different from the Japanese system. NHK, the Japanese version of HDTV was analog, but the updated version created by U.S. researchers has come to be fully digital.
Unlike BETA VCRs and 8 track players, HDTV is a form of technology that is built to withstand the test of time.
With decades of development and research that have gone to optimize the HDTV system, this form of television is likely to last for decades to come.
