[M4IF Technotes] Question on AAC object type

[Anil Kumar]

Hi all,
	I had a couple of questions on the AAC LC object type in a bitstream.
1. Can I get an ADTS or ADIF as the transport layer for an MPEG-4 stream?? (i guess it is yes, but just to confirm).
2. What is the object type index for AAC LC in case of MPEG-2 and MPEG-4. Does this change depending on the transport layer(ADTS or ADIF or GA).
3. How do I distinguish b/w MPEG-2 and MPEG-4 in case of ADIF/ADTS (Is it the bitstream_type and adts_id)
4. Where can I get a complete documentation of all these things??
Thanks in advance,
Anil
