AudioMuteOn, AudioMuteOff
Diagnostic Nucleus AudioMuteOn switches the audio mute on.
Diagnostic Nucleus AudioMuteOff switches the audio mute off.
Correct operation cannot be detected by the Diagnostic Software but must be checked externally.
Note: The audio will be muted by the DAC.
AudioPinkNoiseOn, AudioPinkNoiseOff
Diagnostic Nucleus AudioPinkNoiseOn will generate a pink noise internally on the ZiVa5 chip, which will be passed
to the DAC where it is converted to an analogue audio signal.
Diagnostic AudioPinkNoiseOff will switch off the pink noise generated with AudioPinkNoiseOn.
The signal will also be passed to the digital outputs. For a 6 channel player the signal must be available on all 6 analogue
audio channels.
Correct operation cannot be detected by the Diagnostic Software but must be checked externally.
AudioSineOn, AudioSineBurst
Nucleus AudioSineOn will generate a sine signal of 1 kHz on the analogue output. The sine signal digital data are stored
in the audio buffer in the SDRAM, passed through the audio decoder and without any further processing to the audio
DAC where it is converted to an analogue audio signal.
The signal will also be passed to the digital outputs.
Correct operation cannot be detected by the Diagnostic Software but must be checked externally. The sine signal can
be stopped by pressing the STOP key on the DVD player or by sending a '#' character via hyperterminal.
Nucleus AudioSineBurst will generate a sine signal of 1 kHz on the analogue output that lasts for about four seconds.
The generation of the signal is the same as in AudioSineOn.
Correct operation cannot be detected by the Diagnostic Software but must be checked externally.
Note: In the player script the test AudioSineOn will be used.
VideoColDencOnPAL, VideoColDencOff, VideoColDencOnNTSC
Diagnostic Nucleus VideoColDencOnPAL enables colour bar (PAL format) in the DENC in the ZiVa5 chip.
Diagnostic Nucleus VideoColDencOff disables colour bar in the DENC and the digital video outputs in the ZiVa5 chip.
Diagnostic Nucleus VideoColDencOnNTSC enables colour bar (NTSC format) in the DENC in the ZiVa5 chip.
The signal must be simultaneously available on the RGB, Y/C and CVBS outputs. The RGB and CVBS signals will be
present on the SCART, while the Y/C signal will only be available on the Y/C connector.
Correct operation cannot be detected by the Diagnostic Software but must be checked externally.
VideoProgMPEGon, VideoYuvMPEGon (for SD5.2 only)
VideoProgMPEGon outputs a colourbar pattern on the TV using the external progressive board connected to the
DVD module.
VideoYuvMPEGon outputs a colourbar pattern on the TV using the external "enhanced-YUV" board connected to
the DVD module.
VideoScartLo, VideoScartMi, VideoScartHi (for SD5.2 only)
VideoScartLo steers pin16 on the SCART connector with the value Low (0 to 2V)
VideoScartMi steers pin16 on the SCART connector with the value Medium (4.5 to 7V)
VideoScartHi steers pin16 on the SCART connector with the value High (9.5 to 12V).
Correct operation cannot be detected by the Diagnostic Software but must be checked externally.
DispVer (for SD5.2 only)
Gets the version number of the slave processor on the Display PWB.
