GDB 400 DVD User Guide

The broadcasters assign the channel list numbers. Because not
all channels are broadcast free-to-air, the channel list numbers
may not run continuously.
When you press a number key on the remote control, a small
box appears in the top left of the screen to show the entered
number. After each digit is entered, the Set top box will wait up
to 2 seconds for the next digit to be pressed until either three
digits have been entered or you do not press a digit in time.
The channel corresponding to the entered number in the box
will then be selected.
If you enter a number that does not correspond to a stored
channel, the next valid channel number is selected instead. If
you enter a number greater than the highest numbered channel
in the channel list, the Set top box will select the last channel
in the list.
When you change channels by pressing “P+ or P-” or entering the
channel number, you will always see the I-BAR together with the
audio and video of the channel you had selected. See illustration
below:
Icons are also displayed in the I-BAR if the current program has
digital teletext available and if this channel is a favorite channel.
If the channel selected is locked for parental control, you must enter
the correct 4-digit code to view the channel. You may press “P+ or
P-” to move to another unlocked channel.

4.4 Adjusting the Volume
Press “V+ or V-” on your remote control to adjust the volume.
When you adjust the volume, the volume scale is displayed on the
screen. Press “Mute”on the remote control to turn the sound off
and on again.
The volume level selected will remain set, even when the Set top
box is turned OFF and ON again, until it is altered with the “V+ or
V-” buttons.
4.5 Digital Teletext
Your Set top box can display digital teletext if the channel you are
watching broadcasts digital teletext. Digital teletext may not be only
broadcast pictures and sound for programs but also pages of
information on the programs, the weather, news and many other
topics.
Some channels are designated for digital teletext and carry no
normal TV program at all. Therefore, you cannot see any preview of
these channels inside the Channel List or EPG. When such channel
is selected, after a brief pause, they will usually display the opening
page of information automatically.
There are other channels also that have digital teletext pages
broadcast with TV program and often included a reduced-size
broadcast picture within digital teletext pages. To activate the digital
teletext pages, you need to press the “Text” button of your remote
control.
Bringing up the I-BAR or pressing any menu
stops the Set top box from displaying the digital
Teletext pages and are temporarily replaced with
a blank picture while the I-BAR or menu is
displayed. Digital Teletext cannot be accessed if
the Subtitles are enabled.
TIP
The volume of your Set top box is independent with
your TV set. Take note that both volume controls
are in reasonable levels so that when switching
from analog to digital television viewing, or when
you first turn on your TV set, the audio level will not
be too high.

4.6 Widescreen
TV sets are available with 2 different screen formats, which are
standard [4:3] format and widescreen [16:9] format. During your first
time installation, you will have specified the format of your TV
screen, this can be changed at any time if necessary.
Digital terrestrial television broadcasts are combination of both
standard and widescreen formats. In particular, films and dramas
tend to be broadcast in widescreen format to closer emulate the
cinema experience, but some news bulletins are widescreen. To
achieve the best viewing from both TV set and program when a
widescreen film is watched on a standard TV, or a standard
broadcast is viewed on a widescreen set, your Set top box has the
“Wide” button for this purpose.
As long as your Set top box has been set up correctly with your TV
set, a wide screen program will always be displayed correctly on a
widescreen set and a standard format program will correctly fill the
screen of a standard format TV.
With a widescreen TV set displaying a standard format program,
the “Wide” button 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 program, the
“Wide” button 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 program. It is called as “pan and scan.”
The effect of the “Wide” button on the picture display is cancelled
by pressing the “Wide” button again, changing channel or turning
the Set top box to standby.
