Setting up Cueing Parameters
1
From the user interface of the D9859, choose Audio & Video > Cueing. The
Cueing page is displayed.
2
From the Cueing Mode drop-down list, choose whether the cueing output
should be DTMF tones or trigger pins.
Tones are standard Dual-Tone Multi-Frequency (DTMF) tones. The tones are
generated at the Cue Tone/Relay output on the rear panel of the transcoder.
Trigger refers to open-collector pins which can be generated at the Cue
Tone/Relay output on the rear panel of the transcoder.
3
If Trigger is selected as the Cueing Mode, choose the pin polarity from the
Trigger Polarity drop-down list. Choose High for the pins to act as open or
floating collectors on an active cueing signal and as ground on an inactive signal.
Choose Low for the pins to act as ground on an active cueing signal and as open
or floating collectors on an inactive signal.
4
If the Cueing Mode is set to Tone, set the number of consecutive tone sequences
to be generated in the Cueing Tone Repeat Count field. Values greater than 1
are provided when a scenario demands repetition to ensure that the ad insertion
equipment receives the signal. You can enter 1, 2, or 3. The default is 3.
5
If the Cueing Mode is set to Tone, enter the Tone Duration of each tone, in
milliseconds, in the range from 0 to 80. The default is 40.
6
If the Cueing Mode is set to Tone, enter the Silence Duration of each silence
between tones, in milliseconds. The duration is in the range from 0 to 80. The
default is 40.
7
From the Relay Mode drop-down list, choose the relay mode that can be
programmed to respond to an Alarm state, Warning statue, or the state of one of
the eight cue trigger pins. The response is generated at the Cue Tone/Relay
output on the rear panel of the transcoder. The following table shows what the
possible field settings are and their relationship to the transcoder output:
