The Player script will give the opportunity to perform a test that

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

5.2.3Structure 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:
