Figure 14-12
On the TV screen a colour bar (generated by nucleus
VideoColDencOn) is visual and the internally generated
pinknoise is audible. By pressing PLAY the user confirms the
test, pressing PAUSE will indicate the sound was inaudible or
incorrect. Pressing NEXT will proceed to the next test; if the
user presses NEXT without pressing PLAY or PAUSE first, the
result of this test will be TRUE (sound ok). By pressing the
NEXT button there will be switched over to the external source,
this must become now visible on the TV screen (using the
SCART). The local display indicates:
Figure 14-13
The internally generated colour bar is still available on the
CVBS and Y/C outputs. And the pinknoise-signal is still
available on the cinch audio outputs. By pressing the PREV
button, the internal generated colour bar becomes visual again.
The test can be left by pressing the NEXT key for more than
one second.
14.2.3 SOUND 2 TEST
The second soundtest is performed by producing a sine sound
(nucleus AudioSineOn). The signal can be stopped by pressing
the STOP-key. The display will show the following message:
Figure 14-14
By pressing PLAY the user confirms the test, pressing PAUSE
will indicate that something went wrong. Pressing NEXT will
proceed to the next; if the user presses NEXT without pressing
PLAY or PAUSE first, the result of this test will be TRUE (sound
ok).
14.3 BASIC ENGINE
14.3.1 VERSION NUMBER
In the basic engine tests, the version number of the Basic
Engine will be shown first, as the following example:
Figure 14-15
By pressing the NEXT key, the Basic Engine tests are started.
14.3.2 TRAY TEST
First, the tray is tested. The purpose of this test is also to give
the user the opportunity to put a disc in the tray of the DVD
player. Some tests on the Basic Engine require that a disc(e.g.
DVD MPTD test disc) is present in the player. At the end of the
Basic Engine tests this tray test will be repeated solely to
enable the user to remove the disc in the tray. The local display
will look as follows:
Figure 14-16
By pressing PLAY or PAUSE the user can toggle the position
of the tray. Note that this test will not contribute to the test result
of the Basic Engine. Pressing NEXT will proceed to the next
test, after the tray has been closed (by the software) if it was
open.
14.3.3 SLEDGE TEST(visual test)
The second Basic Engine test tests the sledge; the user can
move the sledge as many times as desired by using PLAY
(nucleus BeSledgeOut) and PAUSE (nucleus BeSledgeIn).
Pressing NEXT on the local keyboard proceeds to the next test.
Note that this test will not contribute to the test result of the
Basic Engine. The local display will look as follows during the
sledge test:
