SDI7 Dual Channel SD/HD/3G SDI Video Generator module remote commands
Enables or disa
blesablackfield for the active video of the second output
(i.e. SIGNAL 1B or SIGNAL 2B) of the specified generator channel. When
enabled, the second output is digital black (0% flat field); when disabled, the
second output is a copy of the test pattern on the firstoutput(i.e. sameas
SIGNAL 1A or SIGNAL 1B respectively). In e ither case, the ancillary data
(embedded audio, time code, VPID, and u ser-defined data) will be the same
for both out
puts of the specified generator channel.
:OUTPut<1|2>:BLACk?
Returns the setting for the second output (i.e. SIGNAL 1B or SIGNAL 2B)
of the specified generator channel.
:OUTPut<1|2>:DHD SIG_SIG|SIG_ BLK|BLK_SIG
Sets the stream content for dual-stream Level B 3G-SDI formats. This setting
is only used when the :OUTPut<1|2>:MODE is set to MD_2X1080_HD or
MD_2X720_HD.
SIG_SIG sets the content of both streams to the currently selected test signal,
SIG_BLK sets the content o f stream A to the currently s elected test signal and
strea
m B to black, and BLK _SIG sets the content of stream A to black and
stream B to the currently selected test signal.
:OUTP
ut<1|2>:DHD?
Returns the setting for the dual-stream contents for the selected generator
outp
ut.
:OUTPut<1|2>:EAUDio:<A|B>G ROup[n]:STATe <Boolean>
Enables or disables the specified embedded audio group (1-4) of the specifi ed
virtual link (A or B). 3G-SDI formats include embedded audio groups in both
li
nk A and link B. Use the link A command for SD-SDI and HD-SDI formats.
For example, the following command enables group 1 of embedded audio
o
n output 1 for all formats:
:OUTPut1:EAUDio:AGROup1:S TATe ON
The following command disables group 4 of embedded audio on output 2 for
link B of 3G-SDI formats:
:OUTPut2:EAUDio:BGROup4:S TATe OFF
:OUTPut<1|2>:EAUDio:<A|B>G ROup[n]:STATe?
Returns the status of the specified embedded audio group (1-4).
:OUTPut<1|2>:EAUDio:<A|B>G ROup[n]:SAMPLing FRAM|NOFR|ASYN
Sets the sampling alignment status bits for the specified embedded audio group
(1-4)ofthespecified virtual link (A or B). The choices are FRAM (Frame),
NOFR (Frame without Frame Number), and ASYNC (Asynchronous).
