Various snippets of information about Digital Television can be found on the internet. Here are some of the most relevant pieces. If you would like to know more, search in Google for Digital television in Australia.
What is Digital Television?
Digital terrestrial television is an exciting new television technology that is replacing existing Australian free-to-air analogue television. Free to view digital television in Australia provides improved picture and sound quality, widescreen images, extra channels plus a variety of new features.
What does free-to-air digital television offer me?
The four key offerings of free-to-air digital television are Sharper Pictures (including some programs in High Definition), Clearer Sound (including some programs with Dolby Digital), Wide-screen Programs and Extra Channels.
How do I receive free-to-air digital television?
There are two ways to receive digital television.
connect your antenna RF cable to a digital television receiver set-top box then connecting the set-top box to your current analogue television screen using AV (Red/White/yellow) cables.
connecting your antenna RF cable to an integrated digital television set.
Prices for digital television set top boxes range from $100 to over $1000 for a High definition box. Prices of integrated digital televisions start around $2,000.
When will free-to-air digital television be available in my area?
The free-to-air broadcasters are now transmitting their digital television services in all capital cities (Sydney, Melbourne, Brisbane, Adelaide, Perth, Hobart, Canberra & Darwin) and a number of major regional markets, 24 hours a day/7 days a week.
Do I need to upgrade my antenna system?
Probably not. But if after acquiring your new digital television receiver you are experiencing interference problems, you may need to install better cables or even a better antenna.
People with shared antenna systems may need to check the capability of the antenna and signal distribution system in the building to receive digital television.
Where can I see a demonstration of digital television?
Most of the big electrical retail outlets have Digital TV demonstrations.
What is widescreen?
Digital television will be broadcast in widescreen mode. Widescreen television has a different aspect ratio (ratio of width to height) than traditional analogue. The aspect ratio of a widescreen is 16:9, while Australian viewers have been accustomed to viewing a 4:3 aspect ratio since television began in this country.
Widescreen will, in many cases, literally mean you see more of the picture. Most movies are currently made in 16:9 and are converted to 4:3 to allow us to watch them on television or video, so there is a lot of information that you don't see on your television that you would see in the cinema version of the film. Live sporting events will benefit in particular from the extra detail and wider frame.
For some time now television production has been converting to widescreen, both locally and overseas. Widescreen programming is becoming more readily available and will eventually become the global standard.
More stuff about Digital.
The formats are confusing and the standards don't seem to be standard. Our simple guide unravels the mysteries of Australian digital TV.
Australia's first 'free to view' digital television broadcasts began in January 2001. The roll-out has been gradual, but now all five free-to-air broadcasters (ABC, SBS, Ten, Seven and Nine) are transmitting their digital television services in all capital cities - Sydney, Melbourne, Brisbane, Adelaide, Perth, Hobart, Canberra and Darwin - 24 hours a day/7 days a week. The emphasis now is on expanding the coverage and content across the country, with over 20 major regional markets receiving at least some digital programming.
By law, they must simulcast (ie, broadcast both analogue and digital signals) for at least eight years in an area, so if you live in any of the cities named above, you will to be able to use your current analogue television set to receive free to air broadcasts until at least the end of 2008.
After the eight year grace period for your area expires, you will need to buy either a digital set top box for your analogue TV or invest in one of the growing number of integrated digital television sets on the market to receive and display digital transmissions.
When the transition to digital is complete, our analogue PAL system will be replaced by the DVB digital television standard, which was first developed in Europe. Note that again, our system will differ from the US, which is using the American-developed ATSC standard.
'Flavours' of digital broadcasts
The first thing to get your head around is that there are two types of digital TV transmissions, Standard Definition (SD) and High Definition (HD) - neither of which is to be confused with Foxtel Digital, the new pay television service which was launched in March 2004. We'll fill you in on the basics.
Standard Definition
SD broadcasts provide widescreen picture with DVD equivalent picture quality. The resolution is 576i (576 horizontal lines interlaced). It is broadcast with MPEG digital stereo sound (similar to CD quality) although some programs may be enhanced with Dolby Pro Logic or Dolby Digital surround sound. This is the standard that is now available 24 hours a day and it’s a marked improvement from the analogue signal. Most late model analogue sets are capable of displaying 576i, however, when connected to a digital set top box.
High Definition
HD broadcasts also provide widescreen pictures, but they have an even sharper image with up to twice the horizontal and almost three times the vertical resolution of SD. The minimum HD picture resolution is 576 lines x 720 pixels @ 50Hz progressive (576p). HD can also be 720p (720 horizontal lines progressive) or 1080i (1080 horizontal lines interlaced). The benefits of HD pictures are particularly noticeable on larger screen sets and when using projection equipment.
The catch, of course, is that HD broadcasts are available on far fewer programs. The Government has imposed HD programming quotas on each broadcaster of at least 1040 hours annually (but only for Sydney, Melbourne, Adelaide and Perth). They've got up to two years after the commencement of digital service to get up to speed in other markets.
The good news is that these quotas are being met and the Digital Broadcasting Australia organisation reports that at present there are almost 50 different shows available in HD on any given week. Some of the programs are 'native' HD (produced in the format), while others have been 'up-converted' from SD format.
If this top-of-the-line picture quality is what you want, make sure before you buy a new big flat screen TV that both the set top box and screen you buy are HD capable, not SD, or you will not be able to fully take advantage of the superior HD image. Expect too, that you will be paying a premium for the HD equipment.
But there's no need to despair if you decide to invest in SD gear. The Federal Government requires broadcasters to provide a digital SD signal at all times, even when HD programs are being broadcast, so you'll always be able to receive a digital television service, even when the higher quality HD signal is being transmitted.
Other digital benefits
In addition to the widescreen view and better pictures and sound, with digital TV you will also receive extra channels. SBS is broadcasting the World News Channel for 20 hours a day in a variety of languages, selected radio channels are available, and most broadcasters are providing program guide channels.
More intriguing is what may evolve from Sydney's market trial of digital data-casting. In addition to extra news, weather, sport and shopping channels, useful community services are being broadcast. You can check out still shots of notorious traffic areas such as the Sydney Harbour Bridge, and surf-cam shots of the major beaches lets you see what surf conditions are like. There is also an audio feed from Parliament House in Canberra if you want to catch every minute of Question Time.
