(file created 2013-03-29, last updated 2013-03-29) MIME media type name : Application MIME subtype name : Standards Tree - dash+xml Required parameters : none Optional parameters : The ‘profiles’ parameter as documented in Annex C.3.1 in this part of ISO/IEC 23009. The 'profiles' parameter is an optional parameter that indicates one or more profiles to which the file claims conformance. The contents of this attribute shall conform to either the pro-simple or pro-fancy productions of RFC6381, Section 4.5. The profile identifiers reported in the MIME type parameter should match identically the profiles reported in the profiles attribute in the MPD itself (see ISO/IEC 23009-1, clause 8). Encoding considerations : 8bit Security considerations : The MPD is a Media Presentation Description and contains references to other resources. It is coded in XML, and there are risks that deliberately malformed XML could cause security issues. In addition, an MPD could be authored that causes receiving clients to access other resources; if widely distributed, this could be used to cause a denial-of-service attack. The Media Presentation Description (MPD) format does not incorporate any active or executable content. However, other forms of material from outside sources can be referenced by an MPD, and this material could contain active or executable content. Such material is expected to be identified by its own MIME type, and the security considerations of that format should be taken into account. If operating in an insecure environment and required by the content/service provider, elements and attributes of MPD may be encrypted to protect their confidentiality by using the syntax and processing rules specified in the W3C Recommendation “XML Encryption Syntax and Processing”. If operating in an insecure environment and required by the content/service provider, the digital signing and verification procedures specified in the W3C Recommendation “XML Signature Syntax and Processing” may be used to protect data origin authenticity and integrity of the MPD Interoperability considerations : Published specification : ISO/IEC 23009-1: Information technology — Dynamic adaptive streaming over HTTP (DASH) — Part 1: Media presentation description and segment formats Applications which use this media : various including but not limited to On-Demand Streaming over the Internet, Live Streaming over the Internet, Internet Video, Internet Radio Additional information : 1.
