2. PLAYER SCRIPT

Purpose of Player Script

The Player script will give the opportunity to perform a test
that will determine which of the DVD player's modules are
faulty, to read the error log and error bits and to perform an
endurance loop test.
To successfully perform the tests, the DVD player must be
connected to a TV set to check the output of a number of
nuclei. For DVDv2B a multi-channel amplifier, a set of 6
boxes and an external video source are necessary to test.
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 Basic Engine module) require that the
DVD player itself is opened, to enable the user to observe
moving parts and approve their movement visually.
Only tests within the scope of the diagnostic software will be
executed hence only faults within this scope can be de-
tected.

Contents of Player Script

The player script contains all nuclei that are useful on a DVD
player that is connected to a TV-set and help to determine
which module of the DVD player is faulty, as well as to read
out the contents of the error logs.

Structure of Player Script

The player script consists of a set of nuclei testing the three
hardware modules in the DVD player: the Display PCB*, the
Digital PCB and the Basic Engine.
*Note: Display PCB tests are not relevant to FW-D1 &
FW-D5 sets
Nuclei run by the player test need some user interaction; in
the next paragraph this interaction is described. The player
test is done in two phases:
1. 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 and
error bits information can be useful to determine any
errors that occurred recently during normal operation of
the DVD player.
2. The loop test will perform the same nuclei as the dealer
test, but it will loop through the list of nuclei indefinitely.
