Screen Layout With Menus
When menus are used, no specific screen layout can be given:
menu information will not be in a special format, except for the
layout as mentioned in the previous paragraphs.
A typical menu session can look as follows:

Depending on the height of the screen, the text will start
scrolling off the top of the screen.
Layout Of Results Diagnostic Nuclei On Control/service Pc
Results returned from a Diagnostic Nucleus to the control/
service PC will have a maximum length of 300 characters and
are terminated by a CR character (included in the string length)
The result has the following layout
< number >< string > [OK l ER] @< CR >
The use of the "@" enables the Asterix system on the Control
PC to parse the output string of each nucleus into a database.
< number > is a 4-digit decimal number padded with leading
zeros if its value is less than 4 digits. The first two digits identify
the generating nucleus (or goup of nuclei), the latter two digits
indicate the error number.
< string > is a text string containing information about the result
of the Diagnostic Nucleus.
< number > and < string > are defined in [SDD_DN] in the
output sections of each Nucleus.

5.11 Diagnostic Nuclei
Each nucleus contains an atomic and independent diagnostic
test, testing a functional part of the DVD player hardware on
component level. Each Nucleus returns a result message to its
caller. Some tests (e.g. generating a colour bar) can only return
an "OK" result. Internal communication will be done via a
uniform interface between the diagnostic Engine, Scripts and
the Diagnostic Nuclei.
The diagnostic Engine can only operate if a certain (minimal)
set of hardware is functioning properly. To test this set of
hardware, a set of basic diagnostic nuclei is embedded in the
DVD player. Each basic diagnostic nucleus will only test that
part of the hardware which is required for execution of the
diagnostic Engine, e.g. a RAM test will only test that part of
RAM that is used by the diagnostic engine. After the Diagnostic
Engine is operational it is possible to do a full RAM diagnostic.
All basic diagnostic nuclei start with prefix 'Basic'.
In the overview each Diagnostic Nucleus consists of a
reference number, a reference name and remarks. Reference
number and name are coupled and one of them is enough for
