5.2 Player Script Interface
5.2.1 Description
The Player script will give the opportunity to perform a test that
will determine which of the DVD recorder's modules are faulty,
to read the error log and to perform an endurance loop test. To
successfully perform the tests, the DVD recorder must be
connected to a TV set.
To be able to check results of certain nuclei, the player script
expects some interaction of the user (i.e. to approve a test
picture or a test sound). Some nuclei (e.g. nuclei that test
functionality of the DVDR module) require that a DVD+RW disc
is inserted.
Only tests within the scope of the diagnostic software will be
executed hence only faults within this scope can be detected.
5.2.2 Structure of the Player Script
The player script consists of a set of nuclei testing the hardware
modules in the DVD recorder: the Display PWB, the Digital
PWB, the Analogue In/Out PWB and the DVDR module.
Nuclei run by the player test need some user interaction; in the
next table this interaction is described. The player test is done
in two phases:
• Interactive tests: this part of the player test depends
strongly on user interaction and input to determine nucleus
results and to progress through the full test. Reading the
error log information can be useful to determine any errors
that occurred recently during normal operation of the DVD
player.
• The loop test will perform the same nuclei as the dealer
test, but it will loop through the list of nuclei indefinitely.
