To start the talkback session you must configure the DEC-
300™ webpage. Please open the DEC-300™ webpage,
300™ webpage, select in the main menu ‘DECODER’ and click in the submenu ‘AUDIO’. See
Figure 10 on page 22.
Enter in the ‘Talkback IP’ field the IP-address of the encoder with which the DEC-300™ should start
the talkback session. For example: A DEC-
300™ should start a talkback session with an ENC-100™.
The encoder has the IP-address 172.16.20.100. So you must enter in the
‘Talkback IP’ field of the
DEC-
300™ webpage the IP-address of the encoder, in this case 172.16.20.100.
Next, the talkback port number must be entered in the ‘Talkback Port’ field. The decoder and the
encoder must always have the same talkback port number. For a talkback session the ENC-100
™
listens always on port 9177 and this port number cannot be changed at the encoder side. So please
enter in the ‘Talkback Port’ field of the DEC-300™ the port number 9177.
Now, you must select in the
field ‘Talkback Rate’ your desired sample rate, which should be used from
the decoder. The decoder and the encoder must always use the same sample rate. So, the set
talkback rate must also be set in the ENC-100
™ webpage. At the encoder side it can be only chosen
between 22.05 kHz and 48 kHz.
Furthermore, please select in the drop-down-
field ‘Input’ the corresponding audio input for the talkback
function. If you supply the DEC-
300™ with the audio signal from a microphone, you must select in the
drop-down-
field ‘Input’ the parameter ‘MIC’. If you supply the DEC-300™ with a line level signal (e. g.:
the audio signal from a DVD-Player), you must select in the drop-down-
field ‘Input’ the parameter
‘LINE’.
You can also set the gain in the fields ‘LineIn Gain’ and ‘MicIn Gain’ for the corresponding audio input,
which you have set in the 'Input' drop-down-field.
The DEC-
300™ is totally configured for a talkback session now. As next you must configure the ENC-
100
™ webpage. At the ENC-100™ encoder side, you must configure in the ‘Talkback’ field the sample
rate, which you have selected on the decoder side. Furthermore you can also set the output gain level
in the ‘LineOut’ field and you can mute the audio of the talkback session by enabling the ‘mute’ check-
box.
Now, you can talkback to your desired ENC-
100™. To stop the talkback session, please enter ‘0.0.0.0’
in the ‘Talkback IP’ field of the DEC-300™.
