3.3 BASIC ENGINE

VERSION NUMBER

In the basic engine tests, the version number of the Basic
Engine will be shown first, as the following example:
By pressing the NEXT key, the Basic Engine tests are
started.

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:
By pressing PLAY 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.
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 PREV (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:
By pressing PLAY the user confirms that the disc motor is
running; pressing PREV 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 PREV, the result of
9-5
this test will be TRUE (disc motor is running).

FOCUS TEST(visual test)

The fourth Basic Engine test tests the focusing; first focusing
is turned on by calling nucleus BeFocusOn. The display will
look as follows:
By pressing PLAY the user confirms that the focusing was
succesful; pressing PREV indicates a focusing failure. Press-
ing NEXT proceeds to the next test after a reset of the
focussing (nucleus BeFocusOff); if NEXT is pressed before
PLAY or PREV, 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:
By pressing PLAY the user confirms that the radial function
worked; pressing PREV 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 PREV, 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:
The user can switch between the three different types of
groove settings by pressing PLAY (forward to next nucleus
in the list In-Mid-Out) or PREV (backward in the list In-Mid-
Out). This is done in a cyclic manner; note that this test will
not contribute to the test result of the Basic Engine. Pressing
NEXT proceeds to the next test, after the disc motor has
been shut off with a call to nucleus BeDiscMotorOff.
