Digital terrestrial tv receiver
Hide thumbs



Many digital terrestrial television channels not only broadcast pictures and sound for programmes but also pages
of information on the programmes, the weather, news and many other topics. This digital teletext can be displayed
by the receiver.Some channels are entirely given over to digital teletext and carry no normal TV programme at all.
These dedicated digital teletext channels will not give a quarter-screen image in the EPG or the Channel List
screen. 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 television programme and often include a
reduced-size broadcast picture within digital teletext pages. These usually require the [TEXT] button to be pressed
to activate the digital teletext pages.In both cases, moving through the different pages of information is
accomplished in a variety of ways, dependent on the individual broadcasters, but including use of the "5/6" and
"3/4" and [SELECT] keys to select items from on-screen menus, and the coloured keys to jump directly to
particular pages.
You can exit any digital teletext channel by changing channel in any of the normal ways. You can leave the digital
teletext function of a combined digital teletext/programme channel, to return to normal television viewing of that
channel, by pressing the [TEXT] key.Calling for the information banner or any menu on-screen stops the receiver
from displaying the digital teletext pages and they are temporarily replaced by a blank picture while the banner or
menu is displayed.Digital teletext cannot be accessed when the Subtitles are enabled


TV sets are available with screens of the standard (4:3) format and widescreen (16:9) format. When you first
installed your receiver you specified the format of the connected TV (this can now be altered if necessary; see
Configuration)Digital terrestrial television broadcasts are also made in both standard and widescreen formats. In
particular, films and dramas tend to be broadcast in widescreen format to closer emulate the cinema experience,
but even some news bulletins are widescreen. To help get the most from both TV set and programme when a
widescreen film is watched on a standard TV, or a standard broadcast is viewed on a widescreen set, the receiver
includes the [WIDE] key.So long as the receiver has been correctly set up for the TV set connected, a widescreen
programme will always be displayed correctly on a widescreen set, and a standard format programme will correctly
fill the screen of a standard format TV.
With a widescreen TV set displaying a standard format programme the [WIDE] key switches between displaying
the picture with black bars down the sides, and enlarging the picture so that it fills the whole width of the screen but
the top and bottom are cropped off.With a standard format TV displaying a widescreen programme, the [WIDE] key
switches between displaying the picture with black bars at the top and bottom of the screen, and filling the whole
height of the screen but cropping the sides off according to instructions broadcast with the programme (called 'pan
and scan').The effect of the [WIDE] key on the picture display is cancelled by pressing [WIDE] again, changing
channel or turning the receiver to standby.

6.8. TV / DTV KEY

If there is no VCR or DVR connected to the STB, the TV/DTV button is used to toggle between TV and STB
modes. When the STB is in TV mode, the TV SCART is not active and the TV operates normally in analogue
mode. When the STB is in DTV mode the SCART is active and the TV is switched to AV/RGB mode. When there
is no menu on the screen, pressing the TV/DVT button will manually toggle the STB between TV and VCR mode.
In VCR mode the STB will display the output of the VCR. In TV mode the STB will display its own output. If the
STB mode is not changed by pressing the TV/DTV button the SCART mode will be automatically detected. (For
example if a dvd player is connected to VCR SCART and powered on , then the set top box will immediately switch
to VCR mode. The set top box will switch to TV mode if dvd player is switched off )
