Flowchart of BD Error Rate Measurement (continuous playback)
Use the following flowchart just as a guide.
The "Read command" is issued.
Transfer Length = 100h = 8 [Cluster]
The "Recorder Command" is issued.
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 + 8
