Introduction:
Digital television provides vastly improved picture and sound quality, including widescreen pictures and digital audio, including radio broadcasts. Digital television also offers the benefits of more channels and content. For example, the ABC has already introduced ABC2 which is only broadcast in digital. SBS has the SBS World News in digital. The Seven, Nine and Ten networks have introduced High Definition digital channels. Network Ten launched a digital-only sports channel, named One, in March 2009. Gradually, each of the free-to-air television broadcasters will be introducing new digital channels and content.
If you wish to continue to receive free-to-air shows, you will need a TV capable of receiving digital signals.
What does an electronic program guide (EPG) do?:
An EPG is the electronic version of a printed program guide. Using your remote control you will be able to see on-screen what's on now and what's on next for all free-to-air services. You may also be able to search for a particular program by theme or category e.g. sporting programs or movies.
Extra text and picture information (such as story line, episode description, etc.) can be called up as well. The EPG is available at the click of a remote control button.
What is closed captioning?:
Closed captioning provides deaf and hearing-impaired viewers with a text version of the dialogue, songs and sound effects included in television programs. The text is usually shown in a black box at the bottom of the picture. Current analog captioning is received on analog receivers with teletext capability. Captioning is normally closed to viewers but can be accessed by those who need it.
Closed captioning does not interfere with normal viewing. Some digital television set top boxes and integrated digital televisions include closed captioning decoding capability.
Consumers intending to purchase a digital television set top box or an integrated digital television and use closed captioning should, before purchase, check on the set top box or integrated digital televisions capabilities.
Closed captioning of programming is incorporated in all English language news and current affairs programs as well as for all prime time programs (6.00pm to 10.30pm).
What does multichannelling provide?:
Because a digital television broadcast signal can carry much more data than analog, it is possible for broadcasters to provide more than one channel of SD programming at the same time. This is known as multichannelling. Turning off analog signals will provide viewers with extra channels, while also freeing up the broadcast spectrum for other purposes such as wireless broadband or mobile phone services.
