18、S 26.111 version 13.0.0 Release 13Foreword This Technical Specification (TS) has been produced 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 c
19、ontents of the present document, it will be re-released by the TSG with an identifying change of 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
20、 document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction In the present document is describ
21、ed additions, deletions, and changes made to ITU-T Recommendation H.324 10 with annex C for the purpose of using that recommendation as a basis for the technical specification for circuit switched multimedia service in 3GPP networks. The present document does not address call setup procedures, but r
22、eferences to the specifications which cover call setup are found in 3GPP TS 26.110 11. ETSI ETSI TS 126 111 V13.0.0 (2016-01)53GPP TS 26.111 version 13.0.0 Release 131 Scope In ITU-T Recommendation H.324 10 with annex C describes a generic multimedia codec for use in error-prone, wireless networks.
23、The scope of the present document are the changes, deletions, and additions to those texts necessary to fully specify a multimedia codec for use in 3GPP networks. Note that this implicitly excludes the network interface and call setup procedures. Also excluded are any general introductions to the sy
24、stem components. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific refe
25、rence, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

36、document contains any deviations to ITU-T H.324 10 required for the specification of 3G-324M Terminals. 5 Document structure The structure of H.324 10 is followed in the present document. Where there are no differences in a specific section, that section is skipped. Where differences are minor, only
37、 the differences are described. Where major differences exist, the section is rewritten in the present document. It is important to note that for wireless terminals, Annex C of H.324 10 supersedes respective portions of the main body of H.324 10 For the present document, these modifications are trea
38、ted as if they are part of the main body of H.324 10 Therefore, a reader must keep in mind both the main body and Annex C of H.324 10 when reading the present document. ETSI ETSI TS 126 111 V13.0.0 (2016-01)73GPP TS 26.111 version 13.0.0 Release 136 Functional requirements 6.1 Required elements 3G-3
39、24M implementations are not required to have each functional element except a wireless interface, H.223 1 with Annex A and B multiplex, and H.245 6 version 3 or later versions for system control protocol. 3G-324M terminals offering audio communication shall support the AMR audio codec. Support for G
40、.723.1 7 is not mandatory, but recommended. 3G-324M terminals offering video communication shall support the H.263 8 video codec. Support for MPEG-4 simple profile and H.261 9 is optional. 3G-324M terminals shall support H.223 1 with annex A and annex B. 3G-324M terminals shall support at least 32 k
41、bit/s minimum bit rate at the mux to wireless network interface. 6.2 Information streams V.25ter discussion does not apply. 6.3 Modem Does not apply. 6.4 Multiplex 3G-324M terminals shall support H.223 1 with annex A and annex B. All other aspects shall follow H.324 10 with annex C. H.223 1 Annex C
42、and D are optional. 6.5 Control channel No differences with H.324 10. Should it not be possible to signal an element of the 3G-324M terminal using a published version of H.245 6, a procedure will be defined here. 6.6 Video channels Support for H.261 9 is optional. Support for MPEG-4 Visual is option

The FLC code 0000 1000 in Table G-1 “FLC table for profile_and_level_indication“ in ISO/IEC 14496-2 14 is assigned to it. Additional information can be found in 14. MPEG-4 Visual Simple Profile level 0 provides error conc
44、ealment as part of the simple profile through Data Partitioning (DP), Reversible Variable Length Coding (RVLC), Resynchronization Marker (RM) and header extension code. MPEG-4 Visual is baseline compatible with H.263 8. When opening a logical channel for MPEG-4 Visual, configuration information (Vis
45、ual Object Sequence Header, Visual Object Header, and Video Object Layer Header) shall be sent in the decoderConfigurationInformation parameter. The same information shall also be sent in the MPEG-4 video bitstream. If the operational mode of MPEG-4 Visual encoder needs to be changed, the existing M
46、PEG-4 video logical channel shall be closed and H.245 6 procedures for opening a new MPEG-4 video logical channel shall be started. The new operational mode shall be indicated in the parameters of the new logical channel. ETSI ETSI TS 126 111 V13.0.0 (2016-01)83GPP TS 26.111 version 13.0.0 Release 1
47、3Support for H.264 (MPEG-4 AVC) 19 is optional. When supported, H.264 codecs shall support Baseline level 1, without requirements on output timing conformance (Annex C of 19). Support for H.264 19 shall be signalled according to H.241 chapter 8 “Capability Exchange signalling“ 20. When opening a log
