Giuliano,
The 3GPP spec that I have states that "MPEG-4 system architectural elements
(e.g. BIFS scene description tracks or OD Object descriptors) are optional
and shall be ignored." (clause 9.2.4).

Hi,
    I know that the iods atom is mandatory in ISO spec.
    Do you know if the iods atom is mandatory in the 3GPP?
