Release notes
Y to GBR convertor mode
of the HDLG7 module
If the output fo
rmat is 2K and the Converter mode is set to Y to GBR, changing
operating mode by selecting a test signal will cause an unexpected black and
white signal to be generated. To correct the test signal, press the OTHER button
until Normal is selected, and then press the test signal button.
25/29.97/30 Hz segmented
frame format for the HDLG7
module
The HDLG7 module does not have format selections for 1080PsF at 25 Hz,
29.97 Hz, or 30 Hz. These formats are almost identical to 1080i (interlaced)
formats at 50 Hz, 59.94 Hz, and 60 Hz respectively; these format settings can be
used with progressive segmented signals. However, note that the SMPTE 352M
payload identifier for the output signal will show an interlaced signal format,
even when
the HDLG7 module is converting a single link progressive segmented
input signal to dual link.
Converter mode of the
HD3G7 mo
dule
Infrequently, the module will fail to up-convert the input HD-SDI signal. If
no outpu
t is seen, the problem can be corrected by selecting a different test
signal and then switching back to converter mode.
The t ri
gger output cannot generate a frame pulse or line pulse when the
module is in converter mode.
The mo
ving picture and video component functions do not apply to
up-converted output signals.
When
a Level B format is selected for the up-converted 3 Gb/s output signal,
embedded audio from the input HD-SDI signal will be copied into both
virtual links. Therefore, up to 32 channels of embedded audio can appear
on the 3 Gb/s output.
The HD3G7 module does not reformat SMPTE 334 Caption Distribution
Packets in c onverter mode. Therefore, when up-converting from 1080i
59.94 Hz to 1080p 59.94 Hz, for example, the output will contain CDP data in
alternate frames, each with 40 bytes of caption data, instead of CDP data in
e
very frame, each with 20 bytes of caption d ata.
Up-conversion to a Level B fast progressive format may result in mis-ordered
Caption Distribution Packets in the stream of output frames.
