Player Script
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.
5.2.3
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
•
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:
Figure 5-3
Pressing the PLAY key will proceed to the slave S/W version
display, which is shown on the local display of the DVD player.
The display will look like the following:
