LETTER

SDTV input signal is set to the letter box mode.

・

 Three rate signals of 3G-SDI/HD-SDI/SD-SDI are automatically recognized. 

・

  When the ACTIVE-THROUGH function is used, both CCU and the camera head have the two return channel speci

fi

cation.  

When the CCU/BS power is not on, through output is not executed. 

・

 SDTV input signal is conformable to the SDI signal only and not VBS. 

・

  When the input signal format switches to a signal that does not require FS while the FS (Frame Synchronizer) is on, the FS does 

not turn off automatically. If FS is not necessary, turn off FS manually.
