F-Board Processing

On EURO 4H models the VDP processor IC601
located on the E-Board has been replaced by an
F-Board. The F-Board contains 4 video processing
ICs, used used to perform a number of functions.
:
50/60Hz to 100/120Hz up conversion for flicker
free picture processing and display
:
Automatic letter box detection for wide screen
transmissions
:
Picture zooming and compression.
