When the video standard is 625:
When the video standard is 625 the 8010TM must get its colour frame information from the External
Colour frame reference input. The COL'R REF LED will be on.
GEN COLOUR FRAME
Col'r frame 2 fld
Col'r frame 4 fld
Col'r frame 8 fld
When the component video is encoded into NTSC or PAL video, there may be frame
delays encountered. These will change the colour frame relationship of the time
code with respect to the video. The colour frame phase can be adjusted by using
the GEN COLOUR PHASE item of the Engineering menu.
Special precautions should be taken when operating in the continuous jam sync
mode.
When the colour frame mode is selected, and the code from the reader does not
have the colour flag set, the generator will maintain a 2 field lock only.
If the 8010TM generator is being operated in the colour frame mode, and the reader
code has the colour flag set, the jam sync process will compare the colour framing
of the reader code against the generator. If the colour framing of the two do not
agree, the JAM indicator will flash on and off at a regular rate. Therefore, if the
playback VTR does not have a colour framer built in, the 2 field mode of operation
should be selected.
OPERATION
Model 8010TM SDI Time Code Master 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 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 4 field PAL
mode. A PAL 4 field 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 PAL 4 field
sequence.
Select Col'r frame 8 fld to configure the generator in the colour frame
mode. A PAL 8 field colour reference signal must be applied to the
Col'r Ref BNC loop in the rear panel. The Front panel COL'R indicator
will be on and code generated will have the colour flag bit set indicating
that the generator numbers are properly synchronized to the PAL 8 field
sequence.
