The Video Wall Controller from Peter's
system showing the I/O ports :-
Video output to the monitors - 9-pin "D"
connectors
Control interface to the computer - 34-way IDC
connectors
RGBS inputs from the video decoder - 15-pin "D"
connectors
The Options page
shows how the components of the Video Wall system were
interconnected.
A clearer view of the I/O ports
The left hand side of the case, showing
the two large cooling fans.
Internal view, from the rear, showing the large PSU and
4 pairs of Frame Memory and Video Controller boards -
the need for the two large cooling fans is obvious.
A view of the array of circuit
boards in the Controller, from the front, showing the
connections to the I/O ports on the rear panel.
The Video Frame Store PCB - 4 or 5 installed
in each card frame of the Video Wall Controller / DDFS chassis
The Controller PCB - 1 installed
in each card frame of the Video Wall Controller / DDFS chassis
The front of the nondescript Video
Decoder module
The rear of the Video Decoder module
showing the I/O ports :-
Video input - BNC
RGBS outputs to the Video Wall controller -
15-pin "D" connectors
The inside of Peter's Video Decoder.

This is much less complex than Mike's, consisting of a
PAL decoder and video amplifier board.
The PAL Demodulator which splits the
composite video signal into RGBS components for the
Video Wall Controller
The Video amplifier which takes the RGBS
component signals from the PAL board and
splits/amplifies the signal to generate 4 RGBS inputs
for the Video Wall Controller.
