Generator
When timecode Generate mode is selected, the controls enable you to enter a specified
starting timecode of the free-running internal timecode generator.
•
Timecode Entry:
In this field you can enter a value to specify when the internally
generated timecode starts. Once set, the internally generated timecode will start when
you select the Timecode Load button. To enter a value:
In the Timecode Entry field, enter the required value and click S to set. To return to the
preset value, click P.
•
Timecode Load:
Manually triggers the internally generated timecode, starting at the
time specified in the Timecode Entry field.
•
30FPS:
Output timecode always follows the correct count sequence for the output
standard, except when following an input timecode that does not represent actual
time (except if the input is flagged as 59 non-drop).
Drop Frame operates as follows:
•
When converting timecode from 29/59 Hz to 29/59 Hz standards, the output
drop-frame type automatically matches the input (the Drop Frame control has no
effect).
•
When using the internal timecode generator with a 29/59 Hz output standard, the
drop-frame type is determined by the Drop Frame control.
•
When converting 23 Hz inputs to anything, follow input will give a broken
sequence.
11.9.3 Embedding
The Embedding controls enable you to enable/disable embedding of VITC in SD output video,
and to choose the line on which it is embedded for both 525 and 625 outputs.
•
VITC Enable:
Enables the embedding of VITC in the SD output.
Note: This control only enables the embedding of VITC. In order for VITC to be
present in the output SD video, a valid timecode must be detected at the input when in
Follow Input mode, or when Generate mode is selected.
•
Output Line (525):
Selects the output line on which VITC is placed when the channel
output is 525. The range is from line 11 to line 17 in one-line steps. The default is line
14.
•
Output Line (625):
Selects the output line on which VITC is placed when the channel
output is 625. The range is from line 7 to line 20 in one-line steps. The default is line
19.
•
Note: The line number stated is the first of the two lines used to embed VITC. The
second line will always be the line se 2. For example, the default line for 525
is 14. Therefore VITC will be embedded on lines 14 and 16.
•
Output Line Status:
Shows the actual output line number on which SD VITC packets
are inserted. If no line number is selected, “OFF” is displayed.
Note: If the line selected is already in use, the VANC embedding hierarchy will place
the SD VITC packet on the nearest available line.
