Switchover To Digital TV

What are high definition (HD) pictures?

High definition digital broadcasts offer a much higher image resolution than what is provided by both SD and the existing analog television broadcasts. Australian broadcasters currently using four different levels of HD image resolutions:

1.    1920 active pixels x 1080 lines @ 50Hz interlaced

2.    1440 active pixels x 1080 lines @ 50Hz interlaced

3.    1280 active pixels x 720 lines @ 50Hz progressive

4.    720 active pixels x 576 lines @ 50Hz progressive

The benefits offered by High Definition (HD) digital pictures are more noticeable on larger TV screens or when projecting on projection equipment. HD pictures are also ghost-free and in widescreen format. When viewed on a HD capable television screen the viewer can enjoy cinema-quality viewing with Dolby Digital sound (where available with some HD programming).

More information is available from the Digital Ready website, www.digitalready.gov.au.

We believe that the difference in picture quality is noticed most on large widescreen televisions or projectors. The bigger the screen the bigger the difference (in general). As we say sometimes in our articles, go into a local retail shop and ask them to show you the difference in image qualities between HD TV, SDTV and Analog Television.

Have your say about the image quality offered by Digital TV:

• Do you notice the difference between High Definition (HD TV) and Standard Definition (SDTV) picture qualities?
• Is it worth switching to Digital Television just for the better images received?
• Are you prepared, or have you, paid the extra money to have High Definition Digital Television equipment to receive HDTV?
