Flowchart of BD Error Rate Measurement (with OK/NG judgment)
Start (during playback)
The "Read command" is issued.
Transfer Length = 100h = 8 [Cluster]
The "Recorder Command" is issued.
(Read Error Information)
Error data are obtained.
Pi1 = Number of ErrNumPi1
Pi1L = Number of UePiLine1
Total Pi1 = Total Pi1 + Pi1
Total Pi1L = Total Pi1L + Pi1L
Total Cluster = Total Cluster + 2

Formula for computation of error rate
• For DVD: See "Error Rate Computation Method for a DVD" .
• For BD: See "Error Rate Computation Method for a BD".
Display Formats on the FL display and as an OSD
Only during playback, if keys are pressed, calculation of error
rate is started, and the results are displayed on the FL display
and as an OSD. The symbol (-) (which indicates that measure-
ment is not finished) flashes.
The result of measurement is displayed.
If error rate measurement is completed before playback
finishes, the average error rate, the symbol (*) (which indicates
that the measurement is completed) and the judgment result
(OK/NG) will be displayed on the FL and as an OSD.
(When NG is displayed, if the tray is opened, the indications on
the FL display and screen will be retained.)
If error rate measurement is not completed before playback
finishes, the average error rate, the symbol (-) (which indicates
that measurement is not finished) and the judgment result
(ERROR) that indicates that the error rate measurement has
not been completed will be displayed on the FL display and as
an OSD.
* For details on the FL display, see "Specifications of Screen Display & FL Display."
www * The layout for OSD depends on the mounting.
* "x.xE-X" in the above table indicates an error rate. E.g.: 3.5E-5 = 3.5X10
