6.2 DVD TEST MODE
The service test mode is used to check functions in fault diagnosis by a serviceman in case of any defect found in the
DVD mecha.
This mode is enabled only when the test mode is activated. At this time, no normal operation is executed.
1. Outline
The service test mode is used to check functions in fault diagnosis by a serviceman in case of any defect found in the
DVD mecha. No general user goes into this mode.
The mode is implemented mainly to check the FE part. It is originally the test mode at the FE part implemented in the
PC communication, which is modified to allow implementation in the HOST communication.
The command for the test mode received in the HOST communication is interpreted by the application part, converted
to the PC communication command and transferred to the OS.
The OS transfers this command to the PC task as if it received the command in the PC communication.
The execution result is noticed to the application part by an e-mail instead of the PC communication.
The application part then transmits the result in the HOST communication to display OSD.
