Release notes
SMPTE309 data usage on
theGPS7module
If ST309 data is
not present on the selected time reference, then the default
SMPTE309 Data mode setting of “Ignore” is the correct selection. For most
applications in which the input time reference does have the ST309 data, then
the setting of “Input” is usually the best choice. While in “Input” mode, the
time zone and DST programming on the input and output are independent,
with the input set by the ST309 data on the input and the outputs being set
by the menu i
n the instrument. This is the best mode of operation even if all
units are set to the same time zone and DST values.
When the SM
PTE309 Data mode is set to “Ignore,” you cannot use the Time
Zone Offset or DST offset controls on the slave unit to adjust the time code
outputs. The reason for this is that the slave unit assumes that the VITC/LTC
inputs are local time and already have such corrections applied. However, you
can offset the time code on individual outputs using the offset controls for each
output. The local time zone and DST settings do affect the master time-of-day
since th
e offsets are subtracted from the input and added to the output, but the
net effect is that the outputs match the inputs unless individually offset.
SMPTE3
09 time zone offset data on individual outputs is not affected by
adjusting time code offsets on individual outputs. The time code offset
controls on the individual outputs does not affect the time zone offset fields in
theoutputtimecodedata.Forexample,iftheslaveunitisconfigured with a
time zone offset of –08:00 and then you also adjust the time code offset on
the SDI7 module Channel 1 by another +03:00 hours, the SMPTE309 data on
that
output will still read –08:00 in the time zone offset field even though the
actual output is UTC –05:00 hours.
The
applied DST offset display is incorrect when the SMPTE309 Data mode
is set to “Use as Input/Output.” When “Use as Input/Output” is selected, the
Applied DST Offset indicator on the slave u nit does not report the actual
DST offset being applied by the system. Instead, the indicator reports the
DST offset that would be applied if the slave unit was using its own DST
offset configuration (as it would in GPS or in VITC/LTC “Ignore” or “Use
a
s Input” m odes).
Embedded audio of the
HDVG7 module
Embedded audio for 720 23.98p/24p formats are not supported for the
HDVG7 module, even though they can be selected in the menus.
The first user data word in the audio control packet (containing the Audio
Frame value) has incorrect parity when the frame count is 1, 2, or 4.
