2. 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located on the E-Board has been replaced by an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.
2.1. I.C. Overview
:
Comb Filter Video Processor IC1501
(VPC3215)
This device converts analogue luminance and
chrominance signals to digital luminance and
chrominance before the signals are processed by the
internal comb filter and colour decoder.
:
Component Interface Processor IC1502
(CIP3250)
This CIP IC is used to convert the analogue RGB and
fast blanking signals to digital and to perform signal
selection.
:
SDA9401 (IC1503)
The SDA9401 on the F-Board provides
up-conversion, vertical zooming, PNR and Automatic
Letter Box Detection (ABLD).
:
Display and Deflection Processor (DDP3310)
IC1504
The DDP is used to provide horizontal scaling,
deflection processing and RGB processing as well as
converting digital YUV to analogue RGB for display.
