Maroochydore, for $79. Since 1 hour of digital recording
takes up 2 Gb of recording space, this 1 Tb drive can
record up to 500 hours of programs. For just an
occasional recording and playback, a 4 Gb flash drive /
memory stick was found good for up to 2 hours. I also
tried an external DVD drive, but this produced a
warning message about unsuitable media.
Antenna
The most fundamental requirement for digital TV is of
course having an antenna that receives a digital signal.
However, if you receive a good analogue signal already
you will probably have no difficulty in this respect.
Analogue signals can “get by” with minor degradation
which may be apparent as snow on the screen, but
digital signals are all or nothing. On the south side of
Buderim Mountain, we needed a booster for analogue
reception on most channels, some of which still tended
to snow. The SD digital reception, still using the same
antenna and booster, is much improved.
I previously tried a Pinnacle USB TV decoder on my
computer which gives full HD reception on some
channels, but only broken up pictures on other
channels, particularly SBS. It appears that High
Definition is more of a problem in this respect because
it requires a much higher bit rate

N.B. Any direct recording device such as an external
hard drive is not shown in this diagram because it
would be connected to the USB port on the front of the
STB. Also,
the power connections are not shown.
When connected as shown, three tuners may be utilised
at any one time, one digital in the STB, one analogue in
the PVR/VCR and one analogue in the TV set. So while
the analogue signal persists, you could be viewing a
current channel on the TV while recording another one
on the PVR/VCR and recording a digital channel via the
STB.
Installation
After making the connections as shown above, switch
on the TV and go to the video channel AV1. Then
switch on the STB (blue LED) using the remote or push
button and follow the instructions on pages 7 & 8 of the
manual. The “Favorites Channel List” is optional; and
the sequence in the manual is topsy-turvey – you need
to do operation 5 “Channel Scan” before you can select
a channel!
Sub-Titles
Being hard of hearing, my wife and I make extensive
use of sub-titles when available. On our analogue TV
this means selecting 801 on the teletext menu each
time we change the channel, and switching it off again
before the channel can be changed.
However, this STB makes sub-titles much more
convenient: once switched on they stay on across all
channels until cancelled. There is nothing about this in
the manual, but just use the SUB-T button on the
remote. Similarly, the EPG button brings up an
electronic program guide for each channel (item 8 in
the manual).
Recording with an external USB flash or hard drive will
be included next month.
