55Adjustments and Settings for Recording : Setting Time DataAdjustments and Settings for RecordingAJ-HPX3000 supports time codes, user bits, date, and time (real time) data, which are recorded as data for the sub-codearea, 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 runand free run.Free run: The time code always advances even whenthe power is turned off. It can be handled astime. It can be slaved to the time code inputthrough the TC IN or DVCPRO connector.Rec run: The time code is recorded as sequentialvalues regenerated as the time code for a cliprecorded on a P2 card.The camera-recorder separately includes two types of userbits: one (UB) is recorded in the sub-code area and theother (VITC UB) in the VIDEO AUX area. Each user bitscan be recorded as any of the following: a user definedvalue, time, date, same value as the time code, frame rateinformation for camera shooting, externally input value(through the TC IN or DVCPRO connector), and valueregenerated as the user bits recorded in a clip on a P2card.The camera-recorder includes only one user definedvalue. If user defined values are selected for both the UBand VITC UB, then the same value is used.Types of UB can be selected in UB MODE and types ofVITCUB can be selected in VITC UB, respectively.However, in the following cases, these are fixed to theframe rate information of the editing machines (editingsoftware for PCs).z For recoding 24P/24PA in 1080i or 480i mode, VITC UBis fixed to frame rate information.z In Native mode, VITC UB is fixed to frame rateinformation.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 whilethe power is turned off and as the time for the user bits anddate data, as well as the reference for file generation timesduring clip recording, which determine the sorting order ofthumbnails and the order of playback. It is also used togenerate clip metadata and UMIDs (Unique MaterialIdentifiers) in the VIDEO AUX area.The CTL counter will measure total recording time afterresetting in the recording operation. On the other hand,this value is the count time and sets the start point of a clipthat can be played back. This can be used to find thecurrent playback position.The camera ID can be set with 10 characters a3 lines,which can be superimposed on the color bar video. It canbe also superimposed along with date and time data.Setting Time DataDescription of time dataTime codeUser bitsDate and time (real time)CTL counterCamera ID
