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. 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 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 will loop through the list of nuclei
indefinitely, till the NEXT key is pressed. The list of
nuclei is as follows:
• VideoColSetupComm
• VideoScartSwComm
• PapChksFlash
• PapI2cNvram
• CompSdramWrR
• PapS2bEcho
• PapI2cDisp
For DSW version 1.6 and above. the DSW version number
will be displayed on the local display. Press NEXT to
continue to the display test.
