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 |
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:
