TC TRK means that timecode recorded on the
tape will be used as the source for the
timecode.
CONV ABS means that the ABS time (subcode)
will be converted to timecode and output as
timecode.

9.2.1 TAPE TC setting

You should only use this setting if you have already
striped the dedicated timecode track with timecode
(either from an external source or from the DA-
78HR's own internal generator).
If you have selected TC TRK
any timecode recorded on the tape will be used as the
tape timecode source.

9.2.2 ABS setting

CONV ABS
If you have selected
the ABS subcode time from the tape will be used as
the timecode, with the start of the tape having a time-
code value of 00:00:00.00, as with the ABS code
itself.
The timecode frame rate used will be the frame rate
as selected in 9.3, "Selecting the frame mode")
NOTE
If you are using ABS timings as timecode, the hours,
minutes and seconds of the ABS time will correspond
to the converted timecode, unless the frame rate is
set to 29.97 non-drop or 30 drop. In these cases, the
difference between ABS values and timecode values
will be about 2 seconds per hour.

9.3 Selecting the frame mode

The DA-78HR can use the following standards for
timecode (including timecode synthesized by the
ABS to TC facility):
Frame mode (fps)
30 non-drop
30 drop
29.97 non-drop

When using the DA-78HR to chase to a timecode
master, the system frame mode on the DA-78HR
must match the frame mode of the timecode master,
otherwise chase operations are not possible.
The system frame mode is automatically set when a
tape which has been striped with timecode is
inserted, (or if power is switched on with a striped
tape already inserted in the unit). The frame mode
recorded on the tape will be used as the system frame
mode.
However, the system frame mode may be changed
following the procedure below.
The system frame mode will determine the type of
timecode output, even if it differs from the tape time-
code (the type of which can be viewed as described
in 9.5.8, "Checking the frame mode of striped time-
code").
The DA-78HR also outputs timecode synthesized
from the ABS code ( CONV ABS
"Tape timecode mode") using the frame mode set
here.
The DA-78HR's internal timecode generator also
uses this frame mode when generating timecode.

9.4 Timecode input and output

Remember in this section, "timecode" means
SPMTE/EBU timecode when referring to incoming
timecode. Outgoing timecode will also refer to
SMPTE/EBU timecode, unless MTC output is turned
on (see 9.4.4, "MTC output").
