[M4IF Technotes] Question on DecodeSpecificInfo

[S.G.Chang]

Dear experts and members.
I have a question on "DecodeSpecificInfo" in MPEG-4 system.
As you know, the "DecoderSpecificInfo" in MPEG-4 system is needed to initialize MPEG-4 decoder.
[ISO/IEC SG29/WG11, N4350, pp 478] says that VisualObjectSequence is transmitted explicitly in each 
DecConfigDecsr.DecSpecificInfo.  
This question is caused by Envivio player. According to our experiments Envivio player can't decode 
"VisualObjectSequenceHeader".
But i can't sure that "VisualObjectSequenceHeader" must be included in "DecodeSpecificInfo" or not. 
If you have information on this, please know me.
