Frame reset signals
The TG8000 uses the three frame reset signals described below to output different
video formats simultaneously.
FRAME RESET 1
This frame reset signal supports the 1/1.001 system signal, and is used by the
following video formats. These signals are synchronized with each other.
NTSC
525-270
1035 59.94i
1080 23.98p
1080 23.98sF
1080 29.97p

FRAME RESET 2
This frame reset signal is used only for PAL, 625, or HD / LTC formats with 50
Hz or 25 Hz frame rates. These signals are synchronized with each other.
PAL
625-270
1080 25p
1080 50i

SET 3
This frame reset signal is used for HD / LTC formats with 60 Hz, 30 Hz or 24 Hz
frame rates. These signals are synchronized with each other.

Not drop frame
Frame reset signal 1 is not synchronized with frame reset signals 2 o r 3 unless
a GPS7 module is installed. When a GPS7 module is installed, the frame reset
signal 1 synchronization is related to the frame reset signals 2 and 3 through
the GPS7 epoch timing.
You can see which of the three frame reset signals are used by e ach output of
each module by using the FRAME RESET STATUS submenu. (See page 2-26,
FR
AME RESET STATUS submenu.)
