When does high definition become the standard on TVs?

Answer 1

I read in an electronics catalog about "What do I do with my TV when it is not HD compatible?" I continued to read since I was wondering the same thing and apparently the federal government is standardizing HD in February of 2009. This should help to dramatically lower the prices of such HD devices like blu-ray players and HD-DVD players and probably current gerneration video game consoles.

Answer 2

False for oodles.

There have been high scan monitors, tv's and projectors for a few decades now but the first HD ( 720 - 1080 ) televisions were on the market in the U.S. in the late 90's. HD CRT,s were among the first then very expensive plasmas.

Invention is probably the wrong work to use for high definition television as it has been a series of developments that allowed HD television to become viable.

In 1925, John Logie Baird demonstrated the first practical television system. Only fourteen years later, he proposed that television should be developed into full color, with 100 lines rather than the 400 in use at the time and he also proposed a 3D television system. In fact he demonstrated 3D in the 1920s.

The introduction of color television happened in the 1950s and 1060s and development work was focused on improving color quality for a number of years. The drive towards high definition gathered pace from the 70s onwards and high definition signal standards were largely agreed by the end of the 1980s. The standards were put together before electronics technology was able to support the required data rates. They triggered research and development around the world to produce camera sensors, storage systems, signal processing, digital compression and displays that would all support the new standards.

The 1990s saw the first demonstrations of HD television but it wasn't until the 21st century that HD was used commercially. It is still in its infancy and there is more work to be done before it becomes a mature technology.

As with so many developments, there can be no date for the start of HD television, but we can pick from several milestones from 1939 through to the 21st century.
