Chapter 4 Adjustments and settings for recording (continued) 5 O To record the user bits of LTC, open the screen from the VTR MENU page by performing menu operations and select "USER" in the UB MODE item. (When the recording format is 720-50P or 72059.94P, set the OUTPUT/AUTO KNEE switch to the "BARS" position in order to record the user bits of LTC in a mode for recording built-in color bar signals.) O To record the user bits of VITC, select "USER/EXT" in the VITC UB MODE item. O The time code/user bits are also recorded in the VIDEO AUX area of the unit's memory. The time code (VITC) is the same value as the sub code area's time code (LTC). The user bits (VITC user bits) can be selected by menu operations using the VITC UB MODE item on the screen which is accessed from the VTR MENU page, and it can be used for different applications from the LTC. O The number of digits that can record user bits may vary with the recording format. When the recording format is 1080-50i or 1080-59.94i CAMERA MODE 24P 24PA User bits All 8 digits can be recorded LTC UB (In accordance with the settings in the UB MODE item) VITC UB Camera shooting information is recorded automatically. All 8 digits can be recorded 60i LTC UB (In accordance with the settings in the UB 50i MODE item) 30P All 8 digits can be recorded 25P VITC UB (In accordance with the settings in the VITC UB MODE item) When the recording format is 720-50P or 720-59.94P OUTPUT/AUTO KNEE switch CAMERA MODE: 60P/50P/30P/25P/24P BARS (Built-in color bar signals) Upper 6 digits can be recorded. LTC UB (In accordance with the settings in the UB MODE item) Upper 6 digits can be recorded. VITC UB (In accordance with the settings in the VITC UB MODE item) CAM (Camera video image signals) LTC UB User bits information automatically. is recorded Upper 6 digits can be recorded. VITC UB (In accordance with the settings in the VITC UB MODE item) O When the recording format is 720-50P or 720-59.94P, operations where FRM RATE or REGEN is selected in the UB MODE item will be the same when USER is selected. Furthermore, operations where TIME is selected in the VITC UB MODE item will be the same when FRM RATE or REGEN is selected. O When only the upper 6 digits of the user bits can be recorded, the remaining lower 2 digits are not recorded. In this case, the user setting value and the lower 2 digits of the time code generator that are selected in the UB 4 MODE item and VITC UB MODE item cannot be recorded. User bit memory function The user bit settings (except for the actual time) are automatically saved in the memory and retained even after the power is turned off. Tape continuity with the user bits (Only when the recording format is 1080-50i or 1080-59.94i) Selecting REGEN for the UB MODE item on the screen by performing menu operations will call up the user bits recorded on the tape, making it possible to continue recording from that value. However, it is not possible to record the contents that were set. Camera shooting information In the unit, the frame rate information (camera shooting mode) indicating the shooting rate and the active frame information (update frame information) indicating the first frame of which frame images are switched are automatically stored as the camera's shooting information into the user bits of LTC (when the recording format is 720-50P or 72059.94P) or the user bits of VITC (when the recording format is 1080-59.94i and the video method is 24P or 24PA). These kinds of information will be output from the TC OUT connector rather than recorded on tape. It will also be overlaid with the HD SDI signals output from the MON OUT connector and VIDEO OUT connector. The active frame information (update frame information) is stored in the lowest digit of the user bits, while the frame rate information (camera shooting mode) is stored in the lower 3rd and 4th digits. To store the camera shooting information into the user bits of LTC and the user bits of VITC in other shooting modes, open the screen from the VTR MENU page by performing menu operations and select "FRM RATE" in the UB MODE item and the VITC UB MODE item. 39
