3.4.13. Selecting the Generator Colour Frame Mode
In most applications the 8010TM will be gen-locked to the program video. It is also necessary to supply
an external colour reference if you desire to apply colour frame synchronization to the generated time
code. This reference is not required when the generator is operated in the 2 field mode.
When the video standard is 525:
GEN COLOUR FRAME
Col'r frame 2 fld
Col'r frame 4 fld
Page 3-16
The GEN DROP FRAME menu item is used to the desired drop frame
mode for the generator.
Select Drop frame off to configure the generator in the non-drop frame
or 'full frame' mode.
Select Drop frame on to configure the generator in the drop frame
mode.
When the 8010TM is in the continuous Jam Sync mode, the generator
drop frame mode is the same as the incoming time code data. The
Drop Frame sub-menu shows Drop frame jam.
When the 8010TM is operating in the 625 line video standard, the Drop
Frame sub-menu shows No drop in 625.
When the 8010TM is operating in time date or Convert mode in the 525
line video standard, it should be operated in the Drop Frame mode so
that the time base is as close as possible to real time.
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 is operated in colour frame mode. This adjustment is
necessary to compensate for frame delays in digital to analog encoders
used in the system.
Select Col'r frame 2 fld to configure the generator in the non colour
frame mode. This is the normal mode for component applications. It is
not necessary to connect a colour reference in the 2 fld mode.
Select Col'r frame 4 fld to configure the generator in the colour frame
mode. An RS-170A colour reference signal must be applied to the Col'r
Ref BNC loop in the rear panel. The Front panel COL'R FRM indicator
will be on and code generated will have the colour flag bit set indicating
that the generator numbers are properly synchronized to the NTSC 4
field sequence.
