HDTV Hype – 7 Marketing Terms and What They Really Mean
Posted by happytown on 31st August 2009
HDTV dealers have two important functions: you the best technology available and help you understand exactly what it is. One way for you to understand new technology come with a simple, descriptive name for it. But sometimes the names are a little too easy, sometimes they are not
descriptive enough, and sometimes they are downright misleading.
Here are seven common HDTV terms that can be misleading orunclear:
HD-Ready
Ready for what? "HD-ready" is the same as "HD monitor." It is an HDTV without a built-in TV tuner, so that an external ATSC tuner or a cable box, will be needed to receive broadcasts. If you only want to use on your HDTV for gaming or DVD can see, it could be better, a few hundred dollars with an HD-ready TV to save.
Native 720p/1080i display
Most HDTV screens are either 768 or 1080 lines of pixels, and a fewhave 900. And all HDTVs have an
inherently progressive display, so the most common native resolutions are 768p, 900p, and 1080p. So, when a manufacturer or merchant claims that an HDTV is “native 720p/1080i”, it usually means that those are the highest resolutions it can handle, and the input is scaled and de-interlaced to fit a 768p display. Some DLP HDTVs, however, do have a native 720p display.
HDTV Antenna
There’s no such thing as a dedicated HDTV antenna. Over-the-air HDTV broadcasts use the UHF frequencies, such as public access TV. Thus, the work of a UHF antenna.
Full HD
This refers to a 1080p display with a screen resolution of 1920 x 1080 pixels and displays the ability, 24, 30 or 60 frames per second. The concept is not wrong, but it means that 720p or 1080i content is somehow incomplete. Since Neary all HD content these days is still 720p or 1080i, which would be nice
Dismalfor HDTV owners.
HD1080
Sets with the name "HD1080" have 1080 lines of pixels and a progressive display, so that they can be properly called 1080p. But they have only 1024 or 1280 pixels in each row, so they do not have the maximum resolution of 1920 x 1080 A 1080i or 1080p signal would be downscaled in the horizontal direction, the change of an image with a set of square pixels in a rectangle with a smaller amount. This does not change the basic look of the videoContent, but cause problems when you use the HDTV as a computer monitor.
Motion Flow, Auto Motion Plus, Clear Frame, Clear Motion Drive
These are all brand names for the new 120Hz high frame rate display technology. Will be high definition TVs with this feature is usually smooth motion display, because they can show 120 different images per second, instead of the typical 60th
Upconverting 1080p DVD Player
Many DVD players are entitled to Upconvert to content1080p, as opposed to 1080i. This is unnecessary, since all have HDTV and LCD displays, and there is no visible difference between 1080i and 1080p content upconverted content upconverted. The transfer from the "i" to "P" is a de-interlacing, and this task is carried out by the TV anyway. The only advantage would be if there is a low-quality HDTV (with a poor de-interlacer) and a high-quality DVD player with a good de-interlacer.
