HDReady
or FullHD Display
Berlin, 2008-11-12, It seems like only yesterday that high-definition
TVs were being touted as the ultimate in colour and clarity.
And many believed it: more than 5.000 in Great Britain and
more than 25.000 HD-ready televisions have been sold in
Germany since 2005. But now an even newer standard, called
full-HD, is being hawked that promises to deliver even better
picture quality.
So what’s the difference? In straightforward terms, a full-HD
screen consists of more lines of pixels than a standard
HD-ready set, and the more lines that a screen contains
the better the picture quality it can theoretically offer.
Full-HD TVs have 1,920 vertical lines and 1,080 horizontal
ones. However, it is the horizontal number that is commonly
used for comparison and regular HD-ready sets have 768,
while standard definition (SD) models have just 576 visible
lines.
The set makers claim that this means full-HD models offer
pictures with finer detail and more subtle colours. The
reason is that most HD programmes, such as Sky’s pay-TV
broadcasts or Premiere have 1,080 horizontal lines and HD-ready
sets must perform some digital jiggery pokery to display
these pictures. A full-HD set can show this HD footage without
resizing the images.
