This document contains a specification for H.324 based multimedia codecs for circuit switched 3GPP networks. The term codec is usually associated with a single 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 handle 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, error 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.

This TS introduces the set of specifications which apply to 3G-324M multimedia terminals.
