ISMA does not have/set/include an MPEG-4 standard, but 
makes clear reference to Profiles and Levels from the 
MPEG-4 Visual and MPEG-4 Audio standards.
Does that answer your question?

Dear All,
Hi, I got a hand on the ISO (14496) MPEG4 standard and understand that 3GPP
MPEG4 standard is based on what ISO specified. 
However, I cannot see any correlation on ISMA MPEG4 standard to other MPEG4
standards.
Could anyone explain a bit on ISMA standard to me please?
Thanks a lot!
cheers,
Eric
