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.

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.

∙ 13y agoInvention 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.

How do you connect a standard definition TV to a high definition satellite receiver?
You can connect your standard definition TV to your satellite receiver in a couple of ways. First, if your TV has composite video/audio inputs (yellow, red, and white RCA jacks), you can connect to these inputs using the composite video outputs of the satellite receiver. Another alternative is to use the standard coaxial cable output from your satellite receiver to connect to the 75ohm antenna input on your TV. *Note: Neither of these connections will display high definition programming on your standard definition TV. The TV is only capable of standard definition, so you will see a clear picture, but it won't be true high definition, regardless of the input signal's definition.
Does a high definition signal work on an analog tv?
only with a converter box, but then it becomes just standard definition
Is DirectTV compatible with a high definition television?
DirectTV is a satellite broadcast platform delivering both standard and high definition television. As all high definition televisions will handle both SD and HD content, DirecTV is fully compatible.
Do you need a high definition tv to have a blu ray player?
To watch in high definition, you must have an HD television with an HDMI connection. However, using the analog outputs from a Bluray player, any standard definition television can be used.
Is the Sylvania VCR compatible with a high-definition TV?
All VCR's work with High Definition tv's,but you'll usually only be able to play back and record in standard definition or Super VHS.
What makes high def better than standard picture?
High definition television is better than the standard picture because it offers a more clear and sharper image in the picture. High definition also has a much higher screen resolution.
How does high difinision tv work?
The answer starts with standard definition television because HD is based on the principles of standard definition. What follows is a greatly simplified description of both and a lot of detail has been left out, but the principles are accurately described. An image is broken down into many individual lines. Each line has hundreds of individual colors. Each line is broadcast one by one and when they reach a television, the lines are put together in order to create a complete image. Standard definition television is created using 480 lines or 576 lines. High definition uses 720 or 1080 lines. The way the images are delivered is much the same as standard definition but the way the colors are encoded provides a better color quality than conventional standard definition. High definition needs far more information to create an image than standard definition, about 5 times as much in fact. This means that all components that are used in high definition television need to operate at much higher frequencies to be able to handle the extra information. It is this higher frequency operation that is perhaps the biggest change between standard and high definition systems.
Can a Blu-ray disc play on a High-Definition TV?
Yes it can and needs an HD television to be seen in the best quality. A Bluray player will also work with standard definition televisions using the analog outputs they usually have. The content will only be seen in standard definition of corurse.
What does SD stand for in Televisions?
In context of television definitions, with HD standing for high definition, SD stands for standard definition - meaning all non-HD televisions signals.
