Many digital terrestrial TV channels not only broadcast pictures
and sound, but also pages of information
on the programmes, weather, news and many other topics. Some channels are given over entirely to
digital teletext and carry no programme at all. When such a channel is selected, after a brief pause, they
will usually display the opening page of information automatically.
Other channels have digital teletext pages broadcast alongside the TV programme and often include a
reduced size broadcast picture within the teletext page. To open
these pages you must press the TEXT
button on the remote control.
In both cases, moving through the different pages of information
is accomplished in a variety of ways,
dependant upon the individual broadcasters, but include the use of the

buttons and “OK”
button, to select items from “on screen”
menus and the coloured buttons to jump to particular pages.
To exit the teletext function press the “TEXT”
button again.
Calling for the information banner, or any menu on-screen stops the racier from displaying the teletext
pages and they are replaced by a blank picture while the banner or menu is displayed.
Note :- Digital Teletext cannot be displayed while subtitles are enabled.
There are some channels carrying MHEG5 data which brings more plentiful information and more
powerful interaction, such as “Hidden Channels”
eg
BBC Sport. If a station is carrying MHEG5 data you
will be informed to press the RED button to select that option.
After MHEG5 has started there will be some operational hints on the TV screen to enhance its operation.
Subtitles.
Press the “SUBTITLE”
button to switch the Subtitles feature On and Off.
Displaying Programme Information
.
You can see the current status and information by pressing the “INFO”
button on the remote control.
This will “time out”
in 3 –
5 seconds.
TV Format.
You can change the TV picture aspect ratio by pressing the “WIDE”
button repeatedly on the remote
control. When you set the TV shape to 4:3 in the System setting
menu, you can switch the TV format to
“Full Frame”
(no scaling will be done). “Pan Scan”
(stretch by 4:3 in the horizontal axis, typically when
the incoming picture is 16:9 widescreen format) or “Letterbox”
(stretched by ¾
in the vertical axis,
typically the incoming picture is 16:9 widescreen format).
When you set the TV shape to 16:9 you can select “AUTO”
(which detects the aspect ratio
automatically), “Full frame”, ”Vertical cut”, (stretch by 4/3 in the vertical axis, typically when the incoming
picture is 4 : 3 format) or “Pillar box”
(stretched by ¾
in the horizontal axis, typically when the incoming
picture is 4 : 3 standard format). The ideal is to watch an un distorted picture on the TV.
Pausing the current picture.
You can freeze the current picture by pressing the “PAUSE”
button on the remote control.
Press the button again to switch the current broadcast back to “Live”.
Note : the broadcast between these two pauses will be lost.
