The IPMP Information Box 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.
