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.

*Note The majority of existing services 11 & 12 were assigned using the "old" channel arrangement (as shown in the above table). Services on channels 10 & 11 may be required to shift frequency upwards 1MHz to align with the "new" channel arrangement. New services on channels 10 & 11 will be  assigned according to the "new" channel arrangements. Once all the existing analogue channel 10s are eliminated, the 6MHz gap between channels 9 & 10 will become 7MHz and an extra channel 9A will be available. Wireless microphones and other devices using the gap frequencies will become obsolete.
