[Mp4-tech] pce() byte alignment inside LOAS/LATM

[Danijel Domazet]

Hi,
Another question related to the byte alignent inside LOAS/LATM transport for 
AAC audio:
program_config_element() (pce for short) is called somewhere within 
LOAS/LATM. pce() is byte-aligned at its end.
Can someone explain if this alignment is related:
1.) only to the bits inside pce()
or
2.) to the LOAS/LATM starting point?
Thanks,
Danijel Domazet
