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 I
12、EC technical committees collaborate 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 J
13、TC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodi
14、es for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.

ISO/IEC 23006-5 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information. ISO/IEC 23006 consists of the following parts, under the general title Informatio
16、n technology Multimedia service platform technologies: Part 1: Architecture Part 2: MPEG extensible middleware (MXM) API Part 3: Conformance and reference software Part 4: Elementary services Part 5: Service aggregation ISO/IEC 23006-5:2013(E) ISO/IEC 2013 All rights reserved vIntroduction ISO/IEC 2
17、3006 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 they are all based on the same set of technologies accessible from the middleware. ISO/IEC 23006 was referred to as MP
18、EG Extensible Middleware (MXM) in its first edition, and it specified an architecture (Part 1), an API (Part 2), a reference software (Part 3) and a set of protocols to which MXM Devices had to adhere (Part 4). ISO/IEC 23006 is referred to as Multimedia Service Platform Technologies (MSPT) in its se
19、cond edition, and it conserves the architecture and design philosophy of the first edition, but stresses the Service Oriented Architecture character. It also specifies how to combine elementary services into aggregated services (Part 5). This second edition has been specified to address the demand o
20、f service specification for an advanced IPTV terminal (AIT). The ISO/IEC 23006 suite of standards also aims at leveraging on advanced technologies to bring into IPTV services the buoyancy of new exciting initiatives sometimes assembling millions of users in a fortnight that pop up almost every day w
21、ith new features such as open APIs and the possibility for third parties to provide applications to those APIs. This enables the development of a global market of: MSPT applications that can run on MSPT devices, such as Advanced IPTV Terminals (AITs), thanks to the existence of a standard MSPT appli
22、cation API; MSPT devices executing MSPT applications thanks to the existence of a standard MSPT architecture; MSPT engines thanks to the existence of standard MSPT architecture and standard APIs; Innovative business models because of the ease to design and implement media-handling value chains whose
23、 devices interoperate because they are all based on the same set of technologies, especially MPEG technologies. INTERNATIONAL STANDARD ISO/IEC 23006-5:2013(E) ISO/IEC 2013 All rights reserved 1Information technology Multimedia service platform technologies Part 5: Service aggregation 1 Scope This pa
24、rt of ISO/IEC 23006 specifies the technology enabling the combination of Elementary Services (ESs) to build Aggregated Services (ASs). It is worth noting that it does not impose the use of any set of technologies but provides a methodology which defines the basic steps for the definition of new ASs
25、and gives some representative examples to help in the understanding of the methodology. It also describes the mechanism for registration of ASs and new ESs not present in ISO/IEC 23006-4. The services registered could be then used in the same way as the ones defined in ISO/IEC 23006-4 for further us
26、age, for instance, for the development of new Aggregated Services. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

39、rn:mpeg:mpegM:schema:06-bpmn-ext-st-NS:2012 4.2 Namespace convention For clarity, throughout this part of ISO/IEC 23006, consistent namespace prefixes are used. “xml:“ and “xmlns:“ are normative prefixes defined in 2. The prefix “xml:“ is by definition bound to “http:/www.w3.org/XML/1998/namespace“.
40、 The prefix “xmlns:“ is used only for namespace bindings and is not itself bound to any namespace name. “xsi:“ prefix is not normative. It is 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 t
41、ext or examples of this specification are not normative, e.g., “mpegmb:“, “bpmn:“. In particular, most of the informative examples in this specification are provided as XML fragments without the normally required XML document declaration and, thus, miss a correct namespace binding context declaratio
42、n. Unless specified otherwise, all unqualified descriptions fragments assume the default namespace “urn:mpeg:mpegM:schema:02-service-NS:2012“. 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
43、 only an informative indication as schema locations may change over time. Table 1 Mapping of prefixes to namespaces used in examples and text.

46、fication of the syntax of tools in XML Schema follows the namespace binding context defined in the relevant schema declaration. 4.3 Conventions Fixed-width font is used to indicate literal machine-readable character sequences. The names of XML Schema attributes appear in fixed-width font in mixed ca
47、se with an initial lower case letter. The names of XML Schema elements and types appear in fixed-width font in mixed case with an initial upper case letter. XML Schema definitions are represented with orange amber background color and a double line black border. XML examples are represented with gra
48、y background color and a single line black border. XML Infosets of MPEG-7 Classification Schemes, XML declarations of Service Types and BPMN 2.0 XML notations are represented with gray background color and a double line black border. 4.4 MPEG-M Elementary and Aggregated Services Registration Authori
49、ty The MPEG-M Services RA is the organization that supports the registration and request of Elementary and Aggregated Services. Registration of Elementary and Aggregated Services shall follow the guidelines included in this part of ISO/IEC 23006. 5 Overview The scope of the MSPT is to support the service providers drive to deploy innovative multimedia services identifying a set of ESs and defining the corresponding set of protocols and APIs to enable any user in an MSPT value chain to access tho
