Dear Experts,
When we get some non meaningful sequence in the bit stream, then are we
suppose to correct the window sequence and, then decode or we have to
decode the sequence as we obtain? 
According to the standard, 
The meaningful block transitions are as follows:
from ONLY_LONG_SEQUENCE to { LONG_START_SEQUENCE
ONLY_LONG_SEQUENCE
from LONG_START_SEQUENCE to { LONG_STOP_SEQUENCE
EIGHT_SHORT_SEQUENCE
from LONG_STOP_SEQUENCE to { LONG_START_SEQUENCE
ONLY_LONG_SEQUENCE
from EIGHT_SHORT_SEQUENCE to { LONG_STOP_SEQUENCE
EIGHT_SHORT_SEQUENCE
In addition to the meaningful block transitions the following
transitions are possible:
from ONLY_LONG_SEQUENCE to { LONG_STOP_SEQUENCE
EIGHT_SHORT_SEQUENCE
from LONG_START_SEQUENCE to { LONG_START_SEQUENCE
ONLY_LONG_SEQUENCE
from LONG_STOP_SEQUENCE to { LONG_STOP_SEQUENCE
EIGHT_SHORT_SEQUENCE
from EIGHT_SHORT_SEQUENCE to { LONG_START_SEQUENCE
ONLY_LONG_SEQUENCE
I am getting some difference with the reference PCM bit streams when I
consider streams with non meaningful window sequence (AL03). 
If the non meaningful window sequence is encountered then what is to be
done? 
Thanking you,
