[M4IF Technotes] SL packet header syntax for MPEG-4:1 in MPEG-2 PES

[Gertzen]

Thanks Dominique,
I suppose that all  Elements needed by a MPEG-4 SL-Header can be taken over by an 
extended  MPEG-2 PES header. This is similar to the RTP header when MPEG-4 is 
streamed over IP.
Conclusion is, that the SL-Header exist, out of the view from MPEG-4 Systems. But 
its bit-length in the PES-Payload is zero. So an individual MPEG-4 elementary 
stream, packed as described in ISO/IEC 13818-1:2000, can be part of a MPEG-4 scene 
without physical modifications. The organisation is part of a DMIF instance to be 
develop for MPEG-2 TS.
Am I right?
Is anybody working on a implementation of a DMIF instance for MPEG-2 TS? 
I already modify a software-based DVB-Multiplexer and Demultiplexer to carry 
individual MPEG-4 elementary streams over a DVB kompliant network. But currently I 
can't demonstrate a live stream based on DVB datastreaming.

Carsten
