Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Telecommunications and
15、Internet converged Services and Protocols for Advanced Networking (TISPAN). ETSI ETSI TR 185 013 V3.1.1 (2009-05) 51 Scope The objective of the present document is to define the set of codecs supported by CNDs for NGN services, on the basis of the service requirements contained in TS 181 005 i.1 and
16、 TS 185 005 i.4, and with reference to the CNDs architecture defined in TS 185 006 i.11 (for communication services) and TS 185 009 i.5 (for IPTV services). Work will address AV/broadcast codecs for IPTV and Conversational codecs for telephony services. It will be fully consistent with the set of co
17、decs identified in TS 181 005 i.1. When TS 181 005 i.1 already specifies a list of codecs for voice services, no new codecs will be added, no codec will be removed nor downgraded in status (mandatory, recommended optional) within this list. For each service (mainly person to person communication and
18、 IPTV) work will be focused on defining subset of default/mandatory which is the only way to guarantee interoperability and avoid transcoding a minimum set of codecs to be supported will be defined. 2 References References are either specific (identified by date of publication and/or edition number
