The present document introduces the set of specifications which apply to 3G-324M multim

21、edia terminals within the 3GPP system. 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 this TS, it will be re-released by the TSG with an identifying change of release date and an i

22、ncrease in version number as follows: Version 3.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 Indicates TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corr

23、ections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the specification; Introduction This document contains a specification for H.324 based multimedia codecs for circuit switched 3GPP networks. The term codec is usually associated with a singl

24、e media type. However, many multimedia services require a close integration of disparate media types. In this sense, the representations of these media types (in the form of media streams) are at least logically bound into a single multimedia stream. As such, a H.324 based multimedia codec must hand

25、le multiplexing/de-multiplexing and skew. It will also have to provide codecs for each of the derived media streams. End-to-end, in-band control is also required for the purposes of configuration and establishing individual media streams. Finally, since 3GPP networks are inherently error prone, erro

26、r detection and/or correction must also be provided by the multimedia codec since it has a comprehensive view of the bit stream it produces and therefore can apply the most efficient form of error detection and/or correction.

40、 ETSI TS 126 110 V15.0.0 (2018-07)73GPP TS 26.110 version 15.0.0 Release 154 General 3G-324M terminals provide real-time video, audio, or data, in any combination, including none, over 3GPP circuit-switched, radio networks. They are based on ITU-T H.324 with Annex C, and Annex H when mobile multilin

41、k operation is supported. Communication may be either 1-way or 2-way. Such terminals may be part of a portable device or integrated into an automobile or other non fixed location device. They may also be fixed, stand-alone devices; for example, a video telephone or kiosk. 3G-324M terminals may also

42、be integrated into PCs and workstations. In addition to 3G-324M to 3G-324M communication, interoperation with other types of multimedia telephone terminals is possible, however a gateway may be required. Multipoint communication between more than two 3G-324M terminals is possible using a Multipoint

43、Communication Unit (MCU). MCU functionality is for further study. 3G-324M terminals are based on ITU-T H.324 with Annex C, and Annex H when mobile multilink operation is supported. For performance reasons and to reference the call set-up procedures, some modifications to H.324 were made. These are d

44、escribed in 3GPP TS 26.111, except call set-up procedures are described in 3GPP TS 24.008, 27.001, 29.007 and 23.108. 3G-324M terminals shall conform to these specifications. Because of the many options in H.324, an implementors guide, 3GPP TR 26.911, provides preferred options for 3G-324M implement

45、ations. Figure 1 below shows the functional components of a generic 3GPP multimedia terminal. The video, speech, data and multilink components are optional. If a media type is supported, the standards indicated are mandatory except those enclosed in square brackets are optional. Figure 1 Scope of ci

46、rcuit switched multimedia 3GPP specification. Items in brackets are optional. Short descriptions of ITU-T H.324, 3GPP TS 26.111, and 3GPP TR 26.911 are given below. 5 ITU-T H.324 ITU-T H.324 describes terminals for low bitrate multimedia communication. That ITU-T recommendation contains “ANNEX C, Mu

47、ltimedia Telephone Terminals Over Error Prone Channels“ (sometimes referred to as H.324/M) and “ANNEX H, Mobile Multilink Operation“. These annexes are considered an integral part of the recommendation. 3GPP TS 26.111 Video I/O Equipment Video Codec H.263, MPEG-4, H.261 Audio I/O Equipment Speech Co

49、TSI TS 126 110 V15.0.0 (2018-07)83GPP TS 26.110 version 15.0.0 Release 15Therefore, herewith H.324 shall mean ITU-T H.324 with Annex C. When multilink operation is utilized, H.324 shall also mean to include H.324 Annex H. Originally designed for V.34 modems, H.324 now supports ISDN and wireless networks. Therefore, it is well suited as a basis for 3GPP multimedia codecs. Relevant to wireless networks, H.324 describes the overall system architecture and introduces control (H.245), mux (H.223), video (H.261 an
