+/**
+ * This box contains information needed by a Content Protection System to play back the content. The
+ * data format is specified by the system identified by the ‘pssh’ parameter SystemID, and is considered
+ * opaque for the purposes of this specification.
+ * <p/>
+ * The data encapsulated in the Data field may be read by the identified Content Protection System to
+ * enable decryption key acquisition and decryption of media data. For license/rights-based systems, the
+ * header information may include data such as the URL of license server(s) or rights issuer(s) used,
+ * embedded licenses/rights, and/or other protection system specific metadata.
+ * <p/>
+ * A single file may be constructed to be playable by multiple key and digital rights management (DRM)
+ * systems, by including one Protection System-Specific Header box for each system supported. Readers
+ * that process such presentations must match the SystemID field in this box to the SystemID(s) of the
+ * DRM System(s) they support, and select or create the matching Protection System-Specific Header
+ * box(es) for storage and retrieval of Protection-Specific information interpreted or created by that DRM
+ * system.
