unless the QAM parameters have been changed since the window was opened.
10.5.2 Tune - Control
After entering or selecting the values in the dialog, click the
Tune
control. This causes the tuner to attempt to find the carrier
detect frame sync and lock on the frequency. Successful tuning results in the three indicators lighting green and the tuner then
attempts to evaluate the bit error rate of the channel. The BER is posted in a few moments if successful.
10.5.3 Apply and Close
When the lights are all green and the BER is posted, click
Apply & Close
to apply and save the settings and close the window.
The 4 set parameters will be copied into the “Demodulator Setting” section.
10.6 Add & Drop Settings
This section displays the local encoder settings in the ‘Add & Drop’ mode only. This
is where local encoder video and audio encoding bit rates and program numbers are
set when the add/drop mode is activated. If the Add/Drop mode is not being used,
encoder parameters are set on the ‘Encoder Settings’ page. In Add/Drop mode,
some parameters can still be set in ‘Encoder Settings’ page, but the ones which
are restricted are greyed out. Programs will automatically be added in this window
when an incoming program is dropped in the ‘PID Display Tree’. Other local encoder
channels may be added into an incoming QAM (if enough bitrate is available) from this
window as required without dropping every program from incoming QAM. Configuring
local programs will force the use of the automatic bit rate configurator, the ‘Set Bit Rates’ button, but the bit rate assigned to
