For the element
@schemeIdUri attribute is used to identify a content protection scheme (for details see ISO/IEC 23009-1 , section 126.96.36.199). This attribute can provide sufficient information, possibly in conjunction with the
@value and/or extension attributes and elements (such as the DRM system(s), encryption algorithm(s), and key distribution scheme(s) employed) for enabling a client to determine whether or not it can possibly play the protected content.
For Representations based on ISO/IEC 14496-12 , content protection schemes (or DRM systems) may be identified with
ContentProtection elements. In this case, a self-assigned UUID URN, as defined in RFC 4122 , indicating the UUID specified in the SystemId field of the PSSH box is used. The usage of the
@value attribute is defined by the protection scheme, however, according to DASH-IF IOP , it is recommended that the
@value attribute is the name of the company system and client version. If used, this can help determine if the current DRM client can play the content. If used differently, the provider of the protection scheme is encouraged to document the alternative usage of the
The following sections collect the Generic Identifiers as well as Protection System Specific ones.
|For Representations based on ISO/IEC 14496-12, it identifies the CENC protection scheme. The value of the @value attribute is the 4CC contained in the Scheme Type Box schm that is within Protection Scheme Information Box sinf, suitably escaped according to RFC 2141 and may include the version number. The 4CC and the version number, if present, are separated by a :. The version number is encoded as up to 8 hexadecimal digits, where the leading 0s may be omitted.
|For Representations based on ISO/IEC 13818-1, it identifies the Conditional Access System. The value of the @value attribute is the 4-digit lower-case hexadecimal Representation of the 16-bit CA_system_ID from the CA_descriptor.
Protection System Specific Identifiers
The identifiers in this table only provides the selected UUID code. For referencing the protection scheme in the
ContentProtection descriptor, the URI
urn:uuid:<uuid> may be used where
<uuid> is to be replaced with the UUID in the first column of the table.
