OPERATION
Model 8010TM-IRIG SDI Time Code Master with IRIG Reader Manual
The GEN COLOUR PHASE menu item is used to adjust the colour
phase relationship of the time code to the colour frame reference when
the 8010TM-IRIG is operated in colour frame mode. This adjustment is
necessary to compensate for frame delays in digital to analog encoders
used in the system.
When the Colour Phase is set to 01 the outgoing time code will be in
time with the 8010TM-IRIG colour reference. The colour phase may be
adjusted by up to 4 frames in PAL and 2 frames in NTSC applications.
This menu item should be adjusted so that the time code colour phase
is in time with the video output of an analog encoder. If the MON
analog output option is installed the colour sequence of the analog
video will be the adjusted by the colour phase offset so that it is in time
with the time code being generated. A time code analyzer such as the
Evertz Model 5300 may be used to verify the correct timing relationship
is being maintained.
The JAM WINDOW menu item is used to ignore the natural differences
between 30 Fps and 25 Fps frames numbers within the second when
the generator is operating in the Convert mode. The frame counting
rates of 25 FPS and 30FPS along with the natural difference between
the video rates of 29.97 and 30 fps (taking into account the dropped
frames) produce an acceptable difference between the 25 Fps and 30
Fps frame numbers during a given second. Any difference between the
active reader input and the generated time code output numbers
(accounting for any programmed OFFSET) will cause the generator to
resynchronize to the reader when the generator is in Convert mode.

factory default setting of "6" frames should be adequate.
