HDTV Tuner 3

This is the right time to do so, if you’re thinking of buying a HD TV. A HD TV or high-definition television uses the digital signals broadcast by television networks and stations. As a result it delivers quality image with CD sound that results is every bit as good as a 35mm movie, with CD sound quality.

Connectivity is a factor to be considered before you make a buying decision. Can you have multiple hookups connected directly to your HD TV without special equipment? A HD TV usually has multiple HDMI inputs and at least one PC input. Some are equipped with as many as 4 HDMI inputs. A rooftop antenna that is compatible with HD TV is worth

buying, and in the case of a satellite system, one that’s designed for use with HD TV.

What exactly is HDTV, and what does it mean for me?

HDTV. You know you want one. We all do. We’ve heard that HTDV offers greater clarity than we’re used to seeing, smoother motion, richer colors, surround sound, and the potential for improved performance from the various pieces of equipment that we want to work together. But before you buy, it’s helpful to understand the technology and its related issues.

First, just buying an HDTV and plugging it into a standard cable box doesn’t give you high-definition television. To watch high-definition TV, you need three components: an HDTV source, an HDTV channel, and the HDTV show itself. Your source, the HDTV set, can display both regular and

HDTV images, but standard analog television displayed on an HDTV set can be disappointing. True, it probably displays a little better than on a standard set, but it is still a far cry from what we expect from HDTV. Also, large screen sets in particular exaggerate the flaws in the standard programming, making them glaringly obvious.

Buying an HDTV can seem an intimidating task. There are so may
different types on the market, with so many different features and specifications that just knowing where to start can cause headaches. However, it doesn’t need to be painful. By following the five steps below, you can make buying an HDTV easy and even pleasurable until the credit card bill arrives, of course.

1. Check the resolution
If you’ve done any research into HDTV, you’ll know that the HDTV specification
covers two resolutions: 720 lines and 1080 lines. So any TV which claims to be
HDTV ready must have a native resolution which has at least 720 lines (this is
usually the second figure quoted. i.e.

if the resolution is A x B, B is the number of
lines.) However, a vertical resolution of more than 720 doesn’t necessarily mean a
TV is HDTV ready. The HDTV specification states that high definition TVs must
support 16:9 widescreen signals (where the width of the picture is 16/9 its height).
That means that in order to display a signal with 720 lines, a TV must have a
horizontal resolution of at least 1280 pixels (720 divided by 9 and then multiplied
by 16)A TV with a vertical resolution of 768 pixels, should have a horizontal
resolution of 1366 pixels.
