The display test is performed by nucleus DispDis play. By
putting a series of test patterns on the local display, the local
display is tested. To step through all different patterns, the user
must either press OPEN/CLOSE (pattern is ok) or STOP
(pattern was incorrect) to proceed to the next pattern. The
display of patterns is continued in a cyclic manner, shown in
Fig. 6, until the user presses PLAY/PAUSE. If the user presses
PLAY/PAUSE before all display patterns are tested, the
DispDisplay nucleus will return FALSE (display test
unsuccessful).
The LED(s) on the DVD player is (are) tested by nucleus
DispLed.
There are three test patterns for the LED test which can be
stepped through using the OPEN/CLOSE key.
The user must check if the LED(s) is (are) lighted; if it is, press
OPEN/CLOSE, if the LED did not light up, the user must press
STOP key. By pressing PLAY/PAUSE before OPEN/CLOSE or
STOP, the Displed nucleus will return TRUE (LED test successful).
In this example, 23 is the hexadecimal code of the pressed
RC key. The user can leave the remote-control test by
pressing PLAY/PAUSE on the local keyboard of the DVD
player. The remote control test is successful if a code was
received before the user pressed the PLAY/PAUSE key.
The remote control of the DVD player is tested by nucleus
DispRc. The user must press any key on the remote control
just once. The codes of the key pressed will be shown on the
local display in hexadecimal format. Example:
Pressing PLAY/PAUSE on the local keyboard again will
proceed to the next text.
If any keys are detected more than once (due to hardware
error), the key-code is displayed twice (or more), with the
second digit increased by 1.
If the user does not press all keys minimally once (in any
order), the DispKeys nucleus will return FALSE and cause an
error in the overall result of the player script.
The user can leave the keyboard test by pressing the
PLAY/PAUSE key on the local keyboard of the DVD player
for at least one full second.
The result of the keyboard test is shown on local display as
follows:
The key-codes displayed on the local display will scroll from
right to left when the display gets full, the text "K" will remain
on display.
