5.2.1 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. For DVDv2b a multi-channel amplifier, a set of 6

speakers 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 detected.

5.2.2 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.

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
•	PapI2cNvram
•	CompSdramWrR
•	PapS2bEcho
•	PapI2cDisp

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:
