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.

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

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
