Q:What is the difference between HDTV and SDTV?
A:There are various types of digital TVs.
A: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.
A: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.
A:Digital TV broadcasting in our country is ultimately orientated towards HDTV.
Q:Can I watch HD broadcasting with all digital TVs?
A:You can receive all digital broadcasts, whether they are SD or HD, using any digital TV. How- ever, 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.)
Q:Can I watch digital TV broadcasting with an analog TV?
A:No.
A:The analog TV cannot interpret digital signals. Therefore, a digital TV is required to watch digital TV broadcasting.
Q:Can I use my present antenna to receive digital broadcasting?
A:As for existing analog TV, digital TV is designed so that digital broadcasting signals are received via both indoor and outdoor antennas.
A: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.
Q:How do I connect an antenna for an apartment or tenement house?
A:Consult the superintendent's office or broadcasting facility administrator for your apartment or tenement house to check whether UHF reception is available.
A: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.
A:Alternatively, your local cable broadcasting company provides a digital TV service, and you can subscribe to it.
A: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.
