By pressing PLAY the script will proceed to the next test. If the user presses PLAY before OPEN/CLOSE or STOP, the DispLed nucleus will return TRUE (LED test successful).5.3.3 Keyboard TestThe keyboard of the DVD player is tested by nucleus DispKeyb. The user is expected to press all keys on the local keyboard once. The code of the key pressed is shown on the local display (1 hexadecimal digit) immediately followed by a (hexadecimal) number indicating how many times that key has been pressed. Example of the local display during this test:Figure 5-7 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.Figure 5-8 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 key on the local display of the DVD player for at least one full second. The result of the keyboard test is shown on local display as follows:Figure 5-9 OrFigure 5-10 Pressing PLAY on the local keyboard again will proceed to the next text.5.3.4 Remote Control TestThe 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.

The user can leave the remote-control test by pressing PLAY 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 key. Pressing the PLAY key, before pressing a key on the remote control, gives an error in the remote control test (note that the remote control test will also fail if a key on the remote control was pressed but no code was received). The remote control test does not check upon the contents of the received code, that is it will not be checked if the received code matches the key pressed. If desired, the user can manually check this code by using a code-table for the remote control key-codes. Figure 5-12 After pressing PLAY, the result of the remote control test is displayed on the local display of the DVD player as follows:Figure 5-13 OrFigure 5-14 Pressing PLAY on the local keyboard again will proceed to the next test.5.3.5 P50 Loop-Back TestFor the P50 loop-back test, the user must first press a key to decide if the test is to be performed.The display will show the following message:Figure 5-15 If the user presses STOP, the P50 test will be skipped.If the user presses OPEN/CLOSE, the P50 test is performed and the result is displayed as follows:Test successful:Figure 5-16 Test fails:Figure 5-17 Press the PLAY key to continue to the next textRC Key id Hexadecimal codeSTANDBY 0C11223344556677889900RETURN 83DISPLAY EFDISC MENU 54SYSTEM MENU 82CURSOR UP 58CURSOR DOWN 59CURSOR LEFT 5ACURSOR RIGHT 5BOK 5CPREVIOUS 21NEXT 20STOP 31PLAY 2CPAUSE 30SUBTITLE 4BANGLE 85ZOOM F7AUDIO 4EREPEAT 1DREPEAT A-B 3BSHUFFLE 1CSCAN 2ACL 16532162_037.eps080102CL 96532065_013.eps120799 CL 96532065_014.eps120799 CL 16532007_004.eps090102CL 16532007_005.eps090102CL 16532007_006.eps090102
