Nucleus 904: System Video Loop
Nucleus for testing the components on the video signal system
path:
•
The VIP
•
The video encoder
•
The VSM
•
The host decoder
•
The analogue board
On the analogue board the video signal will be routed to the
SCART (EUROPE) or CINCH (NAFTA). There it will be looped
back externally by means of the proper cable

Nucleus 905: System Video VBI Loop
This nucleus tests the components on the video signal path:
•
The VIP
•
The VSM
•
The Host Decoder
The video CVBS signal is routed to the output of the analogue
board where it will be looped back by means of an external
cable
Remark: this test is only successful if nucleus 121 is carried out
first.
