19、by the 3rdGeneration Partnership Project (3GPP). The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change o

20、f release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for all changes of substance,

21、 i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. The 3GPP transparent end-to-end packet-switched streaming service (PSS) specification consists of five 3GPP TSs: 3GPP TS 22.233 1, 3GPP TS 26.

22、233 2, 3GPP TS 26.234 3, 3GPP TS 26.244 4, 3GPP TS 26.245 5, and the present document. The TS 22.233 contains the service requirements for the PSS. The TS 26.233 provides an overview of the PSS. The TS 26.234 provides the details of protocol and codecs used by the PSS. The TS 26.244 defines the 3GPP

23、 file format (3GP) used by the PPS and MMS services. TS 26.245 defines the Timed Text format used by the PSS. The TS 26.244, TS 26.245, and Ts 26.246 (present document) start with Release 6. Earlier releases of the 3GPP file format, the Timed text format, and the 3GPP SMIL Language Profile can be fo

24、und in TS 26.234. ETSI ETSI TS 126 246 V13.0.0 (2016-01)53GPP TS 26.246 version 13.0.0 Release 131 Scope The present document includes the specification of the 3GPP SMIL Language Profile. The 3GPP SMIL Language Profile is also referred to as “3GPP PSS SMIL Language Profile“ 3 and also just “3GPP SMI

25、L“. The 3GPP SMIL Language Profile is based on SMIL 2.0 Basic 7 and SMIL Scalability Framework. It is a clean subset of SMIL 2.0 Full profile 7, and a clear superset of SMIL 2.0 Basic 7. The 3GPP SMIL Language Profile is used by the PSS 23 and MMS 6 services. The 3GPP SMIL Language Profile is in no

26、way restricted to be used with only these services, but can also be used for other services. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

37、Basic Profile (and SMIL 2.0 Host Language Conformance) and additional MediaAccessibility, MediaDescription, MediaClipping, MetaInformation, PrefetchControl, EventTiming and BasicTransitions modules. All of the following modules are included: - SMIL 2.0 Content Control Modules - BasicContentControl,

All 3GPP SMIL documents use SMIL 2.0 namespace. 3GPP SMIL documents may declare requirements using systemRequired attribute: EXAMPLE 1: - Namespace URI http:/www.3gpp.org/SMIL20/PSS4/ identifies

41、the version of the 3GPP SMIL profile defined in Release 4 of 3. - Namespace URI http:/www.3gpp.org/SMIL20/PSS5/ identifies the version of the 3GPP SMIL profile defined in Release 5 of 3. - Namespace URI http:/www.3gpp.org/SMIL20/PSS6/ identifies the version of the 3GPP SMIL profile defined in Releas

42、e 6 in the present document. Authors may use these URIs to indicate requirement for exact 3GPP SMIL semantics for a document or a subpart of a document: EXAMPLE 2: The content authors should generally not include the PSS requirement in the document unless the SMIL document relies on PSS specific sem

43、antics that are not part of the W3C SMIL. The reason for this is that SMIL players that are not conforming 3GPP PSS user agents may not recognize the PSS URI and thus refuse to play the document. 6 User Agent Conformance A conforming 3GPP SMIL user agent shall be a conforming SMIL Basic User Agent.

44、A conforming user agent shall implement the semantics 3GPP SMIL as described in clauses 7 and 8 (including subclauses). A conforming user agent shall recognise - the URIs of all included SMIL 2.0 modules; - the URI http:/www.3gpp.org/SMIL20/PSS6/ as referring to all modules and semantics of the vers

45、ion of the 3GPP SMIL profile described in Release 6 in the present document; - the URI http:/www.3gpp.org/SMIL20/PSS5/ as referring to all modules and semantics of the version of the 3GPP SMIL profile described in Release 5 of document 3; - the URI http:/www.3gpp.org/SMIL20/PSS4/ as referring to all

46、 modules and semantics of the 3GPP SMIL profile defined in Release 4 of document 3. NOTE: The difference between release 4 and release 5 is that the BasicTransitions module has been added in release 5. Releases 4 and 5 are defined in 3.

47、3.0.0 Release 13NOTE: The difference between release 5 and release 6 is that the MediaParameter module and additional specification on the ContentControl module systemComponent test attribute have been added in release 6. Release 5 is defined in 3. 7 3GPP SMIL Language Profile definition 3GPP SMIL i

48、s based on SMIL 2.0 Basic language profile 7. This chapter defines the content model and integration semantics of the included modules where they differ from those defined by SMIL Basic. 7.1 Content Control Modules 3GPP SMIL includes the content control functionality of the BasicContentControl, Skip

49、ContentControl and PrefetchControl modules of SMIL 2.0. PrefetchControl is not part of SMIL Basic and is an additional module in this profile. All BasicContentControl attributes listed in the module specification shall be supported. Annex B extends the SMIL 2.0 BasicContentControl specification 7 by additional definitions on the systemComponent test attribute. NOTE: The SMIL specification 7 defines that all functionality of PrefetchControl module is optional. This mean that even although
