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.
The time code is recorded as sequential values regenerated as the time code for a clip recorded on a P2 card.

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.

Description of time data

Time code

The TCG switch can be used to switch between Rec run and free run.

Free run:

CTL counter

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.

Rec run:

User bits

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

zOnly one type of user set value can be recorded.

zFor recoding 24P/24PA in 1080i or 480i mode, VITC UB is fixed to frame rate information.

zIn Native mode, VITC UB is fixed to frame rate information.

Camera ID

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.

Date and time (real time)

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).
