Digital TV
Note:
Digital TV reception is only as good as the antenna and the antenna cabling delivering the DTV
signals to the television. Reliable digital TV reception requires high quality, robust DTV signals which can
only be achieved when using a TV antenna and cabling designed for digital TV reception.
Further reading please visit: http://www.digitalready.gov.au/publications.aspx where you can download
●
‘The Digital TV Antenna Systems for Homes Handbook’ information pdf file.
For your safety, the antenna and cabling should be inspected / installed by a licenced installer that
●
should comply with Australian Standard AS1417.1 for Domestic installations or AS1367 for MATV
installations.
Connecting devices such
as DTV recorder / PVR /
VCR etc that also require
an antenna connection to
the digital television
After digital TV tuning, (or
re-tuning) some or all DTV
channels are missing
Check to ensure your area is covered by DTV transmissions.
●
Check that the aerial and antenna cable are designed for DTV
●
reception. If you live within 5-10 Km of DTV transmission towers,
a combined VHF / UHF Digital TV aerial should be adequate.
Outside this area, separate VHF and UHF aerials provide superior
reception performance.
If you live in a unit or apartment, check to ensure the Master
●
Antenna TV (MATV) system is designed for analogue and DTV
reception. Please consult your body corporate.
To maintain optimum antenna signal quality, use an ‘F’ type
●
TV signal splitter (as illustrated) when connecting two or
more devices to the same antenna socket.
Hint: Some degradation of the DTV signal may occur if you
●
are connecting the aerial through an external device (e.g.
DVD Recorder or Set Top Box). In this case it is better to
use a splitter and connect the aerial directly to both devices.
