The IPMPInfoBox contains IPMP Descriptors which document the protection
applied to the stream.
The IPMP Descriptor is defined in ISO/IEC 14496-1. This is a part of the
MPEG-4 object descriptors (OD) that describe how an object can be accessed
and decoded. In the ISO Base Media File Format, IPMP Descriptor can be
carried directly in IPMPInfoBox without the need for OD stream.
The presence of IPMP Descriptor in this IPMPInfoBox 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
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 IPMPInfoBox if this
media stream is protected by more than one IPMP Tools.
