JVC KM-H3000U Manual De Usuario

supports the following aspect ratio conversion 
methods:

• 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 but the edges of 
the video signal may be cropped.

• 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.

FCFS channels are assigned to either specific inputs 
or bus-pairs. Each bus-pair requires two FCFS 
channels. The bus pairs are as follows:

• PGM – Preset buses
• Key 1 Video – Key 1 Alpha buses
• Key 2 Video – Key 2 Alpha buses
• Key 3 Video – Key 3 Alpha buses
• Aux 1 – not paired
• Aux 2 – not paired
• Aux 3 – not paired

FCFS channels maintain separate settings for 
different switcher video formats. This lets you change 
between switcher video formats without losing FCFS 
channel configurations.

• Using an FCFS channel creates a one frame delay 

for the input video being processed.

single input.

inputs on a specific bus.
