| High Definition Television |
High-Definition Television - a new type of television that
combines a High-Definition Television tuner and an HD-capable display. Almost
all of HDTV’s available in the market use the 16:9 widescreen aspect ratio. An
High-Definition Television tuner can receive analog and digital broadcasts
over-the-air.
High-Definition Television –compatible TV- features only the
high-resolution display and can only receive digital broadcasts if connected
with a separate HDTV tuner. HDTV-ready TVs can have the 16:9 widescreen ratio
or the square like 4:3 aspect ratio.
High-Definition Television has arrived and here to stay given
surging popularity of crystal-clear broadcasts in US television TV. Analog
television’s shift to an all-digital system has heralded a new age in the
65-year history of TV.
Hours of High-Definition Television can be viewed almost nightly.
Viewers can easily determine if a show is presented in High-Definition
Television if the message “Presented in high definition where available” is
shown at the start of a program.
Choosing the right TV is important in the High-Definition Television experience. A TV with a 4:3 screen will be a good choice if local
and network dominate programming are common in your market and over-the-air or
cable High-Definition Television programming is sparse.
However, with the arrival of new technology also calls for viewers
to adapt to the situation. Those still using traditional TV sets will not be
able to get the most out of the High-Definition Television experience.
For this you need to have a tuner to receive and decode
High-Definition Television signals from a source, and a high-quality screen
that can reproduce the outstanding details and colours from an High-Definition
broadcast.
The higher resolution of High-Definition Television makes its
pictures crisper and clearer compared to traditional television. Traditional TV
pictures only possess 480 lines of vertical resolution, while High-Definition
Television has 1,080-line interlaces scan and 720-line progressive scan. The
best quality that can be given by analog TV is 480i, which in contrast is the
lowest quality signal offered by digital TV.
Getting started in High-Definition Television is not as expensive
like during the time it was introduced in the market. Prices of tuners and
HDTVs continue to decline but the quality constantly improves rapidly.
