2. Player Script
2.1 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.
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 detected.
2.2 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.
2.3 Structure of Player Script
The player script consists of a set of nuclei testing the
three hardware modules in the DVD player: the Display
PWB, the Digital PWB, and the Basic Engine.
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: this part of the player test will loop
through the list of nuclei indefinitely, till the player is
reset. The list of nuclei is as follows:
• PapChksFlash
• PapS2bEcho
• PapI2cNvram
• PapI2cDisp
• CompSdramWrR
At the beginning of the tests, the DSW version number will
be indicated on the local display of the DVD.
The display will look like the following:

Pressing the PLAY key will proceed to the slave S/W
version display, which is shown on the local display of the
DVD player.
