National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collabo

12、rate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to de

In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the I

ISO/IEC 2016 All rights reserved v ISO/IEC 23006-2:2016(E) Introduction The ISO/IEC 23006 series is a suite of standards that has been developed for the purpose of enabling the easy design and implementation of media-handling value chains whose devices interoperate because th

19、ey are all based on the same set of technologies, especially MPEG technologies, accessible from the middleware APIs, elementary services and aggregated services. The ISO/IEC 23006 series is referred to as MPEG Extensible Middleware (MXM) in its first edition, and it specifies an architecture (ISO/IE

20、C 23006-1), an API (ISO/IEC 23006-2), a conformance and reference software (ISO/IEC 23006-3) and a set of protocols which MXM Devices had to adhere (ISO/IEC 23006- 4). It specifies also how to combine elementary services into aggregated services (ISO/IEC 23006-5). The ISO/IEC 23006 series is subdivi

21、ded into five parts: Part 1 Architecture: specifies the architecture that can be used as a guide to an MPEG-M implementation; Part 2 MPEG Extensible Middleware (MXM) Application Programming Interface (APIs) (this document): specifies the middleware APIs; Part 3 Conformance and Reference Software: sp

22、ecifies conformance criteria and a reference software implementation with a normative value; Part 4 Elementary Services: specifies elementary service protocols between MPEG-M applications; Part 5 Service Aggregation: specifies mechanisms enabling the combination of Elementary Services and other serv

23、ices to build Aggregated Services.vi ISO/IEC 2016 All rights reserved Information technology Multimedia service platform technologies Part 2: MPEG extensible middleware (MXM) API 1 Scope This document specifies a set of Application Programming Interfaces (called for short MXM APIs) so that MPEG-M Ap

24、plications running on an MPEG-M Device can access the standard multimedia technologies contained in its Middleware as MPEG-M Engines, as specified by ISO/IEC 23006-1. The MXM APIs belong to two classes: the MPEG-M Engine APIs, i.e. the collection of the individual MPEG-M Engine APIs providing access

25、 to a single MPEG technology (e.g. video coding) or to a group of MPEG technologies where this is convenient; the MPEG-M Orchestrator API, i.e. the API of the special MPEG-M Engine (called Orchestrator Engine) that is capable of creating chains of MPEG-M Engines to execute high-level application cal

26、ls such as “Play a video”, as opposed to the typically low-level MPEG-M Engine API calls. 2 Normative references There are no normative references in this document. 3 T erms, d efinitions and abbr e viat ed t erms 3.1 T erms and definiti ons For the purposes of this document, the following terms and

43、e used. “xml:” and “xmlns:” are normative prefixes defined in W3C XMLNAMES. The prefix “xml:” is by definition bound to “http:/ /www.w3.org/XML/1998/namespace”. The prefix “xmlns:” is used only for namespace bindings and is not itself bound to any namespace name. “xsi:” prefix is not normative. It i

44、s a naming convention in this document to refer to an element of the http:/ /www.w3.org/2001/XMLSchema-instance namespace. All other prefixes used in either the text or examples of this document are not normative, e.g. “mpegm:”, “dia:”. In particular, most of the informative examples in this documen

45、t are provided as XML fragments without the normally required XML document declaration and, thus, miss a correct namespace binding context declaration. Unless specified otherwise, all unqualified descriptions fragments assume the default namespace “urn:mpeg:mpegM:schema:02-service-NS:2012”.4 ISO/IEC

46、 2016 All rights reserved ISO/IEC 23006-2:2016(E) In these descriptions fragments the different prefixes are bound to the namespaces as given in Table 1. The schema locations of the namespaces in Table 1 are only an informative indication as schema locations may change over time. T a b l e 1 M a p p
