Adjustments and Settings for Recording Externally Locking the Time Code The unit's internal time code generator can be locked to an external generator. In addition, the external time code generator can be locked to the unit's internal generator. Example of connections for external locking As the figure shows, connect both the reference video signal and reference time code. Example 1: When locking onto an external signal a TC IN Note The system can be configured with multiple units by opening the screen from the SYSTEM SETTING page and setting the GL PHASE item to the connector using menu operations. The phase of the time code can correspond to the VBS output signals of the MON OUT connector. However, the same value should commonly be set to the GL PHASE for all cameras. If different values coexist in the system, the shooting timing may not correspond to each other. Note that when the unit is in the 1080-23.98PsF or 108024PsF modes, it is not possible to lock the time code using the VBS connection with one unit as a reference unit in the manner shown in Example 2. When using these modes, connect the unit in the manner shown in Example 4 and Example 6. GENLOCK IN b a. Reference time code b. Reference video signal Note In place of the HD Y reference signal, composite video signals can be input as the reference video signal. Example 2: When connecting a multiple number of units and using one of them as the reference unit TC OUT c TC IN GENLOCK IN TC OUT c TC IN GENLOCK IN c TC OUT To the next camera c. MON OUT (VBS) Reference unit Reference video signal MON OUT (VBS) Setting of GL PHASE COMPOSIT Setting of GL PHASE Item Variable range Remarks GL PHASE HD SDI For selecting the output signals that lock COMPOSIT phases to the signals that are input in the GENLOCK IN connector. HD SDI: For locking the HD SDI signals to the GENLOCK input. For the down converter output signals, the start position of the video delays by about 90 lines. COMPOSIT: For locking the down converter output signals to the GENLOCK input. For the HD SDI output signals, the start position of the video gains by about 90 lines. Note, however, that in 108023.98PsF mode and 108024PsF mode, the phase is locked to HD SDI even if "COMPOSIT" has been selected. 67 Adjustments and Settings for Recording: Setting Time Data
