Big Screen Television
For the dedicated home theatre buff wanting to get the most out of DVD
the best option is a big (or widescreen),television.
Standard
televisions are almost square, with a screen aspect ratio of 4:3
(for example, 80 cm wide × 60 cm high), however big screen
televisions are designed to accommodate the usual proportions of a
cinema screen picture, with an aspect ratio of 16:9 (for example, 64
cm wide × 36 cm high).
A widescreen television is ideal if it is to
be often used for watching DVDs, and an increasing number of movies
are being broadcast in widescreen ratio on digital television.
A big or
Widescreen television uses an aspect ratio of 16:9, compared with the common
TV aspect ratio of 4:3. At a ratio of 4:3, the width of the screen
is 33% more than the height, whereas at a ratio of 16:9 this is 75%.
The 16:9 aspect ratio corresponds to the normal visual field of
human beings. It will therefore feel more natural to watch and it is
for this reason that most motion pictures are made in this format.
Until recently, widescreen TVs were not made because of technical
and cost reasons. It involves a different technique in creating the
tube and since the production is only limited, it remains expensive
compared with 4:3 TV sets.
