62 Adjustments and Settings for Recording : Setting Time DataThis unit provides time codes, user bits, and day-hour (real time) data as time data, and they are recorded in framessynchronous 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 andfree run.Free run: The time code always advances even when thepower is turned off. It can be handled as time. Itcan be slaved to the time code input throughthe TC IN connector.Rec run: The time code is recorded as sequential valuesregenerated as the time code for a cliprecorded on a P2 card.The following two types of user bits are built in.LTC UB: recorded as LTC, and output from the TC OUTconnector. Also, output as LTC of HD SDIsignals.VITC UB: recorded as VITC (with DVCPRO, recorded inthe VIDEO AUX zone). Also, output as VITC ofHD 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 externalsignals from the TC IN connector.Notesz Only one type of user set value can be recorded.z For recoding 24P/24PA in 1080i or 480i mode, VITC UB isfixed 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 theGPS unit AJ-GPS910G is installed, the built-in clock iscorrected with accurate date and time information from theGPS. This clock is used to store the date and time while thepower is turned off and as the time for the user bits and datedata, as well as the reference for file generation times duringclip recording, which determine the sorting order ofthumbnails and the order of playback. It is also used togenerate clip metadata and UMIDs (Unique MaterialIdentifiers).The CTL counter will measure total recording time afterresetting in the recording operation. On the other hand, thisvalue is the count time and sets the start point of a clip thatcan be played back. This can be used to find the currentplayback position.The camera ID can be set with 10 characters a3 lines,which can be superimposed on the color bar video. It can bealso superimposed along with date and time data.Setting Time DataDescription of time dataTime codeUser bitsDate and time (real time)CTL counterCamera ID
