[Mp4-tech] Turning H.264 and BSAC streams into PES

[Davies, Martin]

Jan,
Thanks very much for that.  It may be possible to put AVC directly into
PES's, but how can you put a synchronised video (H.264) with its audio
(BSAC) stream into an MPEG-2TS?

Martin, 
For carriage of AVC over MPEG-2 (TS and PS), an amendment to 13818-1 is
defined (attached). However, this amendment assumes direct carriage of the
AVC data in PES packets. 
I don't know the DMB specification, but using an MPEG-4 synchronisation
layer for AVC on top of the MPEG-2 one sounds to me as a good step towards
an impressive Tower of Babel, pretty weird. Carriage of MPEG-4 data over
MPEG-2 is defined already around 1999 and is meanwhile included in the
second edition of 13818-1 (2000). Note however that 13818-1 (2000) does not
take any AVC specific constraints and conditions into account as defined in
the attached amendment for direct carriage of AVC in PES packets, which I
believe  are needed to make the system work for broadcast. Good luck !
Best regards,
Jan van der Meer

        Classification:         
In the emerging DMB specification, it appears that H.264 and MPEG-4/BSAC
streams are put through some sort of MPEG-4 synchronisation layer, and its
output is turned into PES's, which can then be inserted into an MPEG-2TS.  
Is there anywhere I can find information on how MPEG-4 streams are turned
into PES's?
Is there any software or hardware available that will do this?
I am equally interested in the decoding side.  After this MPEG-2 transport
stream has been demultiplexed, I would like to know how the original streams
can be recovered from there.
Cheers,
Martin Davies
