AJ-HPX2000 supports time codes, user bits, date, and time (real time) data, which are recorded as data for the sub-code
area, VIDEO AUX area, and 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 or DVCPRO/DV 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 camera-recorder separately includes two types of user
bits: one (UB) is recorded in the sub-code area and the
other (VITC UB) in the VIDEO AUX area. Each user bits
can be recorded as any of the following: a user defined
value, time, date, same value as the time code, frame rate
information for camera shooting, externally input value
(through the TC IN or DVCPRO/DV connector), and value
regenerated as the user bits recorded in a clip on a P2
card.
The camera-recorder includes only one user defined
value. If user defined values are selected for both the UB
and VITC UB, then the same value is used.
Types of UB can be selected in UB MODE and types of
VITCUB can be selected in VITC UB, respectively.
However, in the following cases, these are fixed to the
frame rate information of the editing machines (editing
software for PCs).
z In 720P mode, both the UB and VITC UB are always
frame rate information.
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) in the VIDEO AUX area.
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 a 3 lines,
which can be superimposed on the color bar video. It can
be also superimposed along with date and time data.
