Adjustments and Settings for Recording : Setting Time Data
This unit provides time codes, user bits, and day-hour (real time) data as time data, and they are recorded in frames
synchronous with images, and are also recorded as data for clip metadata files. It also includes a CTL counter and camera ID.
The TCG switch can be used to switch between Rec run and
free run.
Free run: The time code always advances even when the
power is turned off. It can be handled as time. It
can be slaved to the time code input through
the TC IN connector.
Rec run: The time code is recorded as sequential values
regenerated as the time code for a clip
recorded on a P2 card.
The following two types of user bits are built in.
LTC UB: recorded as LTC, and output from the TC OUT
connector. Also, output as LTC of HD SDI
signals.
VITC UB
: recorded as VITC (with DVCPRO, recorded in
the VIDEO AUX zone). Also, output as VITC of
HD SDI signals.
You can select and record each respective user set values,
time, year month day, with the same value as time codes,
camera photo frame rate information, input value of external
signals from the TC IN connector.
Notes
z Only one type of user set value can be recorded.
z For recoding 24P/24PA in 1080i or 480i mode, VITC UB is
fixed to frame rate information.
z In Native mode, VITC UB is fixed to frame rate information.
The built-in clock maintains the date and time. When the
GPS unit AJ-GPS910G is installed, the built-in clock is
corrected with accurate date and time information from the
GPS. This clock is used to store the date and time while the
power is turned off and as the time for the user bits and date
data, as well as the reference for file generation times during
clip recording, which determine the sorting order of
thumbnails and the order of playback. It is also used to
generate clip metadata and UMIDs (Unique Material
Identifiers).
The CTL counter will measure total recording time after
resetting in the recording operation. On the other hand, this
value is the count time and sets the start point of a clip that
can be played back. This can be used to find the current
playback position.
The camera ID can be set with 10 characters a3 lines,
which can be superimposed on the color bar video. It can be
also superimposed along with date and time data.
