Configuring FCFS Channels in Input Mode
Input mode locks a specified FCFS channel to a 
specific input. Table 1  lists the input video formats 
you can convert to the specified switcher video 
format.
To configure an FCFS channel set to Input mode:
1.
Assign an FCFS channel to a specific input.
2.
Use the Input knob to select which input the 
FCFS channel is assigned to.
3.
Use the Frming knob to set the aspect ratio 
conversion mode. You can choose from the 
following:
• Full — The video signal is scaled 
disproportionately to fill the display of the new 
aspect ratio. Aspect distortion occurs as the 
image is stretched/compressed to fit in the 
new aspect ratio.
• Zoom — The central portion of the video 
signal is zoomed to fill the display of the new 
video format. No aspect distortion is 
introduced.
• LttrBx — Black bars are added to the top and 
bottom of a 16:9 image to display correctly in a 
4:3 video format.
• PllrBx — Black bars are added to the right 
and left of a 4:3 image to display correctly in a 
16:9 video format.

Press the Confrm knob to commit the change 
and exit the FCFS menu. Press the Cancel knob 
to return to the FCFS menu for further editing.

Configuring FCFS Channels in Bus Mode
Bus mode locks a specified FCFS channel to a 
specific bus-pair.
To configure an FCFS channel set to Bus mode:
1.
Assign an FCFS channel to a specific bus.
2.
Use the Bus knob to select which bus the format 
converter / frame synchronizer is assigned to.
3.
Use the 2ndCh knob to select the FCFS channel 
to assign to the paired bus.
4.
Press NEXT.

Use the Frming knob to set the aspect ratio 
conversion mode. You can choose from the 
following:
