Digital TV broadcasting generates less noise and provides clearer visuals and sound than analog TV broadcasting does. As services develop, you can also enjoy various information services because various kinds of data besides video and audio can be sent.

For example, while watching a sports game, you can view information 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 receive 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.

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. SDTV 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. (At present, all digital TVs from Samsung Electronics have the 16:9 wide aspect ratio.)

5-3 Troubleshooting

Can I watch HD broadcasting with all digital

TVs?

FAQ

Can I watch digital TV broadcasting with an analog TV?

Can I use my present antenna to receive digital broadcasting?

PLEASE TRY THE FOLLOWING!

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.)

No.

The analog TV cannot interpret digital signals. Therefore, a digital TV is required to watch digital TV 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 antenna.
