3.2 GENLOCK System
3.2 GENLOCK System
This section explains input/output connectors and connection examples of the GENLOCK system for this product.
Input Connectors
REF connectors and SUB REF connectors are explained here.
The phase of output signals can be synchronized with the reference signals input to the REF connectors and SUB REF connectors.
■
REF connectors (Loop-through)
Three types of signals below can be input to the REF connectors.
①
HDTV PS/S (Tri-level sync)
②
SDTV VBS/BBS (NTSC / PAL)
③
BBS + 10 FIELD ID (SMPTE 318M compliant)
[There are cases that 10 FIELD ID is set as an option for the synchronizing signal generator (sync generator).]
■
SUB REF connectors (Loop-through)
When the output format is 1080P/23.98PD (2-3 pulldown), 1080P/23.98, or 1080P/23.98sF (segment frame), the phase of 23.98P and
2-3 pulldown signals can be synchronized by inputting the following signals.

BS-98 as master
Input the HDTV 3 value synchronizing signal with 10 FIELD ID that is output from the SYNC OUT connector of master CCU-
980/BS-98, to the SUB REF connector of the slave CCU/BS.
s7HENTHEPHASEOF0ANDPULLDOWNSIGNALSISSYNCHRONIZEDWITHTHEREFERENCESIGNALS
Input the 23.98P format synchronizing signal to the SUB REF connector. However, when the synchronizing signal in the 59.94I
format is input to the CCU/BS REF connector, phases of the synchronizing signals in the 23.98/P format and in the 59.94I format
must match to each other.)
Output Connectors
SYNC OUT connector and ENC OUT connectors are explained here.
■
SYNC OUT connector
SYNC OUT connector outputs synchronization signals. The format to be selected varies depending on the setting of SYSTEM
FORMAT. (Select a format from the CCU/BS menu.)
SYSTEM FORMAT Format that can be selected in the SYNC OUT of OUTPUT FORMAT
1080P59 1080P59 / 1080I59 / SDTV
1080I59 1080I59 / SDTV
1080P23PD 1080I59 / 1080P23 / 1080P23SF / SDTV

1080I100 1080I50 / SDTV
720P50 720P50 / SDTV
In addition, when the 1080P23PD format is selected, it is possible to select on the menu whether or not 2H pulse is added at every
10 FIELD of 1080I59 (it is not the same as the 10 FIELD ID speci
fi ed in SMPTE 318M; however, it is called as "10 FIELD ID" as
well here).
