Operating Instructions AJ-PX380G
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 <GL IN/VIDEO OUT> terminal.
HD-Y or composite signal that suits the system frame frequency is supplied to the <GL IN/VIDEO OUT> terminal. Select the output signal to lock to the input reference signal in the main menu → [IN/OUT SEL] → [GENLOCK SETTING] → [GL PHASE] (not available for 480i, 576i).
Adjust the horizontal phase of the reference signal and output signal in the main menu → [IN/OUT SEL] → [GENLOCK SETTING] → [H PHASE].
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 → [IN/OUT SEL] → [GENLOCK SETTING].
Selection of external reference signal | Generator lock setting | Output signal status (phase relationship with external reference signal) | |
|---|---|---|---|
System mode | Input signal | [GL PHASE] | |
1080i, 1080P | HD-Y (1080i) | [HD SDI] | 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. |
[COMPOSITE] | 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. | ||
Composite | [HD SDI] | HD SDI output matches the composite input signal. Down converter output has a delay of approx. 90 H from the composite input signal. | |
[COMPOSITE] | Down converter output matches the composite input signal. HD SDI output has an advance of approx. 90 H from the composite input signal. | ||
720P | HD-Y | [HD SDI] | 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. |
[COMPOSITE] | 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. | ||
Composite | [HD SDI] | HD SDI output matches the composite input signal. Down converter output has a delay of approx. 120 H from the composite input signal. | |
[COMPOSITE] | Down converter output matches the composite input signal. HD SDI output has an advance of approx. 120 H from the composite input signal. | ||
480i, 576i | Composite | — | SD SDI output matches the composite input signal. Composite output matches the composite input signal. |
HD-Y | — | SD SDI output is not locked to the HD-Y input signal. Composite output is not locked to the HD-Y input signal. | |
