For example, while watching a sports game, you can view various data
on your favorite player or you can view all or selected screens which
have been captured from different angles for a specific scene. In
addition, you can retrive information on a previous story or drama or you
can buy home shopping products such as an accessory currently on TV.
Digital TV broadcasting allows you to easily access various information
services in your home creating a more information-oriented home.
What is the difference between
HDTV and SDTV? There are various types of digital TVs.
The most widely known types of digital TV are HDTV and SDTV. They
are classified according to the screen quality and the video
specifications.
- HDTV (High Definition TV): High screen quality, very clear TV.
- SDTV (Standard Definition TV): Common standard digital TV.
An SDTV has an aspect ratio of 4:3 which is the same as that of an
analog TV. HDTV has an aspect ratio of 16:9 which is similar to a
cinema screen. This provides a much better screen quality than SDTV.
It's like having a theater in your home.
Digital TV broadcasting in our country is ultimately orientated towards
HDTV.
Can I watch HD broadcasting with
all digital TVs? You can receive all digital broadcasts, whether they are SD or HD,
using any digital TV. However, you cannot enjoy HD programs, which
are the highest quality digital TV programs, using an SD digital TV.
Especially, as SD broadcasting has an aspect ratio of 4:3, HD
broadcasting has an aspect ratio of 16:9, similar to a cinema screen.
Therefore, to enjoy the full benefits of digital TV, it is better to purchase
an HD digital TV.(At present, all digital TVs from Samsung Electronics
have the 16:9 wide aspect ratio.)
Can I watch digital TV
broadcasting with an analog TV? No.
The analog TV cannot interpret digital signals. Therefore, a digital TV is
required to watch digital TV broadcasting.
Can I use my present antenna to
receive digital broadcasting? As for existing analog TV, digital TV is designed so that digital
broadcasting signals are received via both indoor and outdoor
antennas.
If signal reception is very good in your environment, you can watch
digital broadcasts with your existing indoor antenna. If not, it is better to
install an outdoor UHF antenna.
How do I connect an antenna for
an apartment or tenement house? Consult the superintendent's office or broadcasting facility administrator
for your apartment or tenement house to check whether UHF reception
is available.
Even if digital TV broadcasting is available in your area, if you cannot
watch it because the superintendent's office or common broadcasting
facility does not rebroadcast the signal, you have to install an indoor or
outdoor antenna.
Alternatively, your local cable broadcasting company provides a digital
TV service, and you can subscribe to it.
If a cable broadcasting company is sharing a common broadcasting
facility for your apartment or tenement house, it has to adjust and send
digital TV signals so that they are compatible to shared viewing which is
the original purpose of the common broadcasting facility.
