Australian Television Bands

Television System

Australia uses the VHF/UHF PAL B/G television system. In many regional areas, networks broadcast only in the UHF band (PAL G). In capital cities, most networks broadcast in both the VHF band (PAL B) and the UHF band (PAL G). Full teletext information services are available on the Seven network which is available nationwide. Subtitles are available for selected programs on all channels by selecting Teletext page 801. All 5 nationwide free-to-air channels now broadcast in FM-FM Stereo.

The PAL (Phase Alternating Line) system was introduced in the 1960's and was implemented in Australia, New Zealand and most European countries with the notable exception of France who developed their own system known as SECAM. The PAL system utilises a wider channel bandwidth than America's NTSC and therefore delivers higher quality pictures than NTSC.

The Australian DVD Video Region Code is 4.
