Any data already in the ancillary data space can be removed by using this control. Set
ENG’ING:Anc
Data
to
Anc Blnk
to remove all horizontal ancillary space data
.
Note: If the Ancillary data is set to be blanked then ALL data in the horizontal ancillary (HANC) space will be
removed, not just the audio data.
3.7.3 Output EDH
EDH is a method of embedding data within the ancillary data space which carries a measurement of the
video and other data. By regenerating the equivalent measurement at the receiving end it is possible to
check that the data has been received correctly.
HD signals always have the EDH data embedded, but for SD signals it is optional. On the V6334 Audio de-
multiplexer, the EDH on the output can be disabled on the
ENG’ING
:
O/P EDH
menu.
3.7.4 Display Sleep
Since, for the vast majority of its life, the modules will operate behind the front panel of a rack frame the
display on the local front panel will not be visible so it will go to sleep after a certain time. This timeout
delay can be changed on the
ENG’ING
:
Sleep
menu to be anything between 0 and 30 minutes; 0 minutes
means that it will stay on indefinitely. The sleep timeout always counts from the last front panel button
push. The default time is 5 minutes.
The panel can also be forced into its sleep mode by moving up a level from the Top Level menu which
displays the module type,
V6334Q/D
etc.
To get the display to come on again simply press one of the buttons and the menus will start again at the
Top Level.
3.7.5 Display Brightness
The brightness of the front panel display can be adjusted on the
ENG’ING
:
LEDLevel
menu.
