/**
* The <i>IPMP Information Box</i> contains IPMP Descriptors which document the
* protection applied to the stream.
*
* IPMP_Descriptor is defined in 14496-1. This is a part of the MPEG-4 object
* descriptors (OD) that describe how an object can be accessed and decoded.
* Here, in the ISO Base Media File Format, IPMP Descriptor can be carried
* directly in IPMP Information Box without the need for OD stream.
*
* The presence of IPMP Descriptor in this box indicates the associated media
* stream is protected by the IPMP Tool described in the IPMP Descriptor.
*
* Each IPMP_Descriptor has an IPMP_ToolID, which identifies the required IPMP
* tool for protection. An independent registration authority (RA) is used so
* any party can register its own IPMP Tool and identify this without
* collisions.
*
* The IPMP_Descriptor carries IPMP information for one or more IPMP Tool
* instances, it includes but not limited to IPMP Rights Data, IPMP Key Data,
* Tool Configuration Data, etc.
*
* More than one IPMP Descriptors can be carried in this box if this media
* stream is protected by more than one IPMP Tools.
