Basic Engine
5.5.1
Version Number
In the basic engine tests, the version number of the Basic
Engine will be shown first, as the following example:
Figure 5-24
By pressing the NEXT key, the Basic Engine tests are
started.
5.5.2
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 5-25
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.
5.5.3
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:

Disc Motor Test (Visual Test)
The third Basic Engine test tests the disc motor (nucleus
BeDiscMotorOn); the local display looks as follows:

Figure 5-27
By pressing PLAY the user confirms that the disc motor is
running; pressing PAUSE indicates the disc motor does not
work. Pressing NEXT proceeds to the next test, after a reset
of the disc motor (nucleus BeDiscMotorOff). If the user
presses NEXT before pressing PLAY or PAUSE, the result of
this test will be TRUE (disc motor is running).
Focus Test (Visual Test)
The fourth Basic Engine test tests the focussing; first
focussing is turned on by calling nucleus BeFocusOn. The
display will look as follows:
Figure 5-28
By pressing PLAY the user confirms that the focussing was
succesful; pressing PAUSE indicates a focussing failure.
Pressing NEXT proceeds to the next test after a reset of the
focussing (nucleus BeFocusOff); if NEXT is pressed before
PLAY or PAUSE, the result of this test will be TRUE (focus
successful).
Radial Test (Visual & Listening Test)
The fifth Basic Engine test tests the radial functionality
(nucleus BeRadialOn); the local display looks as follows:
Figure 5-29
By pressing PLAY the user confirms that the radial function
worked; pressing PAUSE indicates the function does not
work. Pressing NEXT proceeds to the next test, after a reset
of the radial (nucleus BeRadialOff). If the user presses NEXT
before pressing PLAY or PAUSE, the result of this test will be
TRUE (radial successful).
Jump Test (Listening Test)
The sixth and last Basic Engine test tests the jumping by
calling nuclei BeGroovesIn, BeGroovesMid and
BeGroovesOut. During this test, the local display looks as
follows:
