TV has come a long way since the first set received a static-filled and scratchy sounding broadcast in the last century.
When 3D viewing first debuted it was on the big screen and required special glasses. Now, it’s come to the home and does not require the glasses. All the major TV makers are offering 3D capable TV sets and more and more broadcasters are offering 3D programming.
Combined with a good home stereo system for sound, a large 3D TV can provide a view experience just like being in movie theater.
3D TV is most common in the United States with Poland coming in a close second. Most of the 3D broadcasts are available only in some countries. HIGH TV 3D and WildEarth are available worldwide.
3D TV started in the 80s, but was the traditional type which required glasses to properly see it. 3D without the need for glasses started in 2010. Sports broadcasts dominated the first offerings and continue to be the major users of 3D TV technology.
HDTV is best defined as 1080p (progressive scan), 1080i (interlaced scan) or 720p. The 1080p is 2.1 megapixels per frame with the 1080i 2.1 megapixels or 1.6 megapixels per frame depending on the complete resolution. The 720p is .9 megapixels per frame. While global, this is not a universal standard.
HDTV efforts started about the same time TV was launched, but it was impractical at the time. The first modern attempt at HDTV was in Japan in the 60s. Testing continued for years, but problems with combing different formats was a major headache.
In the late 70s, four different versions of HDTV were tested by the Society of Motion Picture and Television Engineers (SMPTE). It took the development of digital video broadcasting to really bring HDTV to the masses in the early 2000s.
The switch from analog to digital broadcasting is probably the most fundamental shift in TV tech in since television began. In the United States, when the Federal Communications Commission announced airwave broadcasters were moving from analog to digital, Congress authorized a massive spending bill to let people use federal money to buy converter boxes.
Digital TV was common in the cable industry before it moved to the public airfare broadcasting. The switch meant TV stations around the nation had to invest in new technology.
