Chapter 4 Shooting - Selection of external reference signal and generator lock setting Selection of external reference signal and generator lock setting Locking the video signal to the external reference signal The video signal output from the camera can be locked to the reference signal supplied from an external source. The camera can receive external reference signals from the terminal. Generator-locking to the reference signal supplied from the terminal The HD-Y signal or a composite signal matching the system frame frequency is supplied to the terminal. To enable the reference signal input to the terminal, the switch needs to be set to . Select the output signal to lock to the input reference signal from the main menu → [OTHER FUNCTIONS] → [GL PHASE] (in 1080i, 1080P, and 720P only). Adjust the horizontal phase of the reference signal and output signal in the main menu → [OTHER FUNCTIONS] → [H PHASE]. @@NOTE tt The subcarrier of the composite signal of the camera is not locked to the subcarrier of the reference signal. Output status The output status changes as follows according to selection of the external reference signal and generator lock setting. Set [GL PHASE] in the main menu → [OTHER FUNCTIONS]. Selection of external reference signal System mode Input signal 1080i/1080P HD-Y Composite 1080/23.98PsF HD-Y 720P HD-Y Composite 480i/576i Composite HD-Y Generator lock setting [GL PHASE] [HD SDI] [COMPOSITE] [HD SDI] [COMPOSITE] [HD SDI] [HD SDI] [COMPOSITE] [HD SDI] [COMPOSITE] - - Output signal status (phase relationship with external reference signal) HD SDI output matches the HD-Y input signal. Down converter output has a delay of approx. 90 H from the HD-Y input signal. Down converter output matches the HD-Y input signal. HD SDI output has an advance of approx. 90 H from the HD-Y input signal. HD SDI output matches the composite input signal. Down converter output has a delay of approx. 90 H from the composite input signal. Down converter output matches the composite input signal. HD SDI output has an advance of approx. 90 H from the composite input signal. HD SDI output matches the HD-Y input signal. HD SDI output matches the HD-Y input signal. Down converter output has a delay of approx. 120 H from the HD-Y input signal. Down converter output matches the HD-Y input signal. HD SDI output has an advance of approx. 120 H from the HD-Y input signal. HD SDI output matches the composite input signal. Down converter output has a delay of approx. 120 H from the composite input signal. Down converter output matches the composite input signal. HD SDI output has an advance of approx. 120 H from the composite input signal. SD SDI output matches the composite input signal. Composite output matches the composite input signal. SD SDI output is not locked to the HD-Y input signal. Composite output is not locked to the HD-Y input signal. @@NOTE tt In the system mode of 1080P or 720P, a genlock is applied to the video signal when the HD-Y signal is input. In this case, time code may shift by one frame. tt Down converter output refers to the output from the and terminals. - 96 -
