2.3.2 Setting up the TV service:
When the demodulator is receiving OK as explained in the previous section, the TV service parameters
should be set up. Please refer to the menu in Figure 2.
2.3.2.1 Selecting which TV service to be decoded
First you must select which TV service you want to decode. Enter the
TV Service
menu and find a list
of services that can be seen by using the up and down arrow keys. Select the service you want to see by
pressing the right arrow key. Note that the demodulator must be working OK for you to find this list. If
there is no list of services, check the demodulator status and setup again. Also the service ID can be
typed in manually if this is known, and can thus be configured without the signal being present.
If you have connected a TV monitor to the composite output and speakers to the audio outputs (see
sections 3.3 and 3.4 for detailed description of the video and audio connectors, respectively), you
should now have sound and picture.
For a more detailed description of the
TV service
menu, please see section 5.4.2.
2.3.2.2 Selecting Language
If more than one language is sent in audio (and video), teletext subtitling, and teletext, the desired
language may be selected in the
TV language
menu. Please select the preferred language from the
existing predefined priority lists (the priority list can be viewed by scrolling the menu under the selected
language.) If no predefined list applies to the languages of your choice, please select the
User def.
entry which gives you the option of manually selecting the language codes for all the components. This
is done by entering the three-letter language code (e.g.
nor
for norwegian).
You should now have picture and sound with the correct language components.
For a more detailed description of the
TV language
menu, please see section 5.4.3.
2.3.2.3 Selecting video format
The TT1200 supports PAL, PAL M, SECAM and NTSC composite video. Please enter the
Video
format
entry and select the video format that is appropriate for your configuration.
The TT1200 automatically detects whether the input signal is 525 lines (NTSC) or 625 lines (PAL or
SECAM) video and outputs the composite video according to this. For example, if the original signal is
625 lines, but
Video format
is set to
NTSC
(525 lines), the actual output is 625 lines PAL. But if
there is no appropriate input signal, there will be a black NTSC signal at the composite output in this
case. This means that the
Video format
entry is used for the following two purposes:
1.
Select between PAL and SECAM output for a 625 lines video signal (the menu also includes a
PAL CN option, for future use), and between NTSC and PAL M for 525 lines video.
2.
Select between 525 lines and 625 lines video format for black video output when no appropriate
input signal is available.
2.3.2.4 Enable or disable subtitling – PAL or SECAM
The
Subtitling
entry is used to enable or disable subtitling. Note that subtitling is only available for
PAL or SECAM video, and that this menu entry is only active if
PAL
or
SECAM
is selected in the
Video format
menu. TT1200 supports two types of subtitling:
