If you are thinking about experiencing the latest in HD TV technology, there are a few important areas to take into consideration. Firstly, what do you intend to watch? There has been a lot of buzz around High Definition TV lately and it is important to consider the HD TV Channels being offered in Australia. Secondly, not all HD technology is the same, so it is important to know what equipment is best.

While Australia is an early adopter of high definition television, recently digital terrestrial television looks at being more popular. This isn’t to say that High Definition TV isn’t worthwhile as there are many HD TV Channels available to the consumer. For example, the Australian government allocated the five national terrestrial television stations (ABC, SBS, Seven, Nine and Ten) one channel each which they are required to broadcast a simulcast of the analogue offerings in High Definition TV format with at least 20 hours per week of HD TV content. This push from the Australian government provides for free to air HD TV Channels available to the consumer.

While the free to air offerings are fantastic for experiencing regular programming in high definition for the Australian people, most consumers would be looking for other content in the high definition High Definition TV format. HD TV Channels such as sports or documentary type programming are popular choices for consumers and as such have been a strong offering from pay TV providers offering High Definition TV.

While HD TV Channel content is an important consideration, this should be balanced with knowledge of the formats and technology that are used in the HD TV spectrum. With High Definition TV there are two main formats; 1080i and 720p. In the case of 1080i, the HD TV picture may have 1080 interlaced or progressive scan lines. 1080i offers 1920×1080 pixel resolution and displays more information in the way of scan lines. This means sharper pictures particularly with slow moving images. 720p offers 1280×720 pixel resolution and while offering less resolution to 1080i, 720p offers full frame, progressive scanning enabling fast-moving action without blurring the image.
