The Protection Scheme Information Box contains all the information

required both to understand the encryption transform applied and its parameters, and also to find other information such as the kind and location of the key management system. It also documents the original (unencrypted) format of the media. The Protection Scheme Info Box is a container Box. It is mandatory in a sample entry that uses a code indicating a protected stream.

When used in a protected sample entry, this box must contain the original format box to document the original format. At least one of the following signaling methods must be used to identify the protection applied:

a) MPEG-4 systems with IPMP: no other boxes, when IPMP descriptors in MPEG-4 systems streams are used; b) Standalone IPMP: an IPMP Info Box, when IPMP descriptors outside MPEG-4 systems are used; c) Scheme signaling: a Scheme Type Box and Scheme Information Box, when these are used (either both must occur, or neither).
