6.13.2. Closed Caption Control

6.13.2.1. Loss of CC Timeout
This parameter enables the user to set the amount of time (in seconds) before the Closed Captioning
timeouts when the video is lost. To set the Loss of CC Timeout, drag the slider right to decrease or left to
increase the value. The value range is 1 to 600 seconds with a default value of 180 seconds.
6.13.2.2. SD CEA-608 Waveform Line (+CC option only)
The SD CEA-608 Waveform Line parameter enables the user to the set the waveform line from 10 to 25.

6.13.3. CC Generation Control (+CC option only)

6.13.3.1. Caption Erase Timer
The Caption Erase Timer control is used to erase the caption display. When enabled, the 7812UDXD
will activate an internal timer and clock the time delay between processing caption data. If caption data is
not detected for a period of 15 seconds, the 7812UDXD will encode a clear caption command. This
command will be used by downstream decoders to clear the caption display. This control can either be
enabled or disabled from VistaLINK .

6.13.3.2. Caption Shift Up Lines
This control enables the user to set the baseline of the CEA-608 captions up from 2 to 4. The Caption
Shift Down Lines control is identical. For the sake of brevity, only Caption Shift Up Lines will be
discussed in the manual.

6.13.4. Misc System Control (+CC option only)

6.13.4.1. DST In Effect
This control is used to indicate whether Daylight Saving Time (DST) is currently in effect. The DST
setting will be used to calculate the current local time, and to set the DST flag in XDS packets.
When set to Off, Daylight Saving Time compensation will not be applied. When set to On, Daylight Saving
Time compensation will be applied to the time.
6.13.4.2. DST Observed
The DST Observed control allows the user to specify whether Daylight Saving Time is observed in their
locale. This is used to calculate the current local time, and to set the DSO flag in XDS packets. For
regions that observe Daylight saving time, the DST Observed setting must be set to On, and for regions
that do not observe Daylight saving time, the DST Observed setting must be set to Off.
