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 SYNC 10FLD connectors are explained here.
The phase of output signals can be synchronized with the reference signals input to the REF connectors and SYNC 10FLD
connectors.
■
REF connectors
Three types of signals below can be input to the REF connectors.
① HDTV PS/S
② SDTV VBS/BBS
③ BBS + 10 FIELD ID
■ SYNC 10FLD connectors
When the output format is 1080I/59.94 (2-3 pulldown), 1080P/23.98, or 1080P/23.98 (segment frame), the phase of 23.98P and 2-3
pulldown signals can be synchronized by inputting the following signals.
• When the phase of 2-3 pulldown signal of another CCU-890 is synchronized by using a CCU-890 as
master
HDTV tri-sync signals with 10 FIELD ID output from the SYNC OUT connector of another CCU-890
• When the phase of 23.98P and 2-3 pulldown signals is synchronized with the reference signals
Synchronization signals in 23.98P format
(When synchronization signals in 59.94I format are input to the REF connectors of the CCU, the synchronization signals in 23.98/P
format must be in phase of the synchronization signals in 59.94I format.)
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 output video signal. (Select
a format from the menu.)
HD-SDI OUT1/OUT2 FORMAT Synchronization Signal Format to be Selected
1080I59. 1080I59./SDTV
1080I59.PD 1080I59./1080P23.SF/1080P23./SDTV
1080P23.SF
1080P23.
720P59. 720P59./720P23./SDTV
In addition, when a format other than 1080I59. and 720P59. is selected, whether to add 2H pulse every 10 FIELD (this is different
form the 10 FIELD ID specifi ed by SMPTE 318M.; however. this is also called "10 FIELD ID" here.) can be selected.
■ ENC OUT connector
10 FIELD ID can be added to the ENC signal. (The 10 FIELD ID described here indicates the ID specifi ed by SMPTE 318M.)
Note:
When the format of the camera head is 1080I/59.94 (2-3 pulldown), the phase of 2-3 pulldown signal needs to be synchronized even if
the 2-3 pulldown signal is not used for the CCU output since the 2-3 pulldown signal is transmit and received between the camera head
and the CCU.
