value of 0x08. For the DSM-CC icon, the following text is displayed:
■ PID: Shows the PID value of the data DSM-CC
■ Type: Shows the type of the DSM-CC
GHOST
One or more transport packets with a PID value not
specified in the PSI or Private Section PID file when the
transport stream is downloaded. For the GHOST icon, the following text is displayed:
■ PID: Shows the PID value of the GHOST
NULL
One or more transport packets with a PID value of
0x1FFF. For the NULL icon, the following text is displayed:
■ PID: Shows the PID value of the NULL
■ Status LEDs : Each element in the ASI transport stream has a status LED to
indicate the status of the associated stream element as follows:
■ A green LED icon indicates that no errors have been detected in the
element since the monitoring session was started or since the last session
reset.
■ The LED icon turns red for 5 seconds when an error is detected.
■ After 5 seconds of an error-free condition, a red LED icon turns yellow
to indicate that an error occurred in the past. The LED turns red again if
another error is detected.
Use the Error Log display to view reported errors. See Error Log display on
page 123.
