30、se 131 Scope The present document reports the study on video enhancements in 3GPP multimedia services. It firstly provides an overview of the video codecs and their configurations specified for existing 3GPP multimedia services, namely 3GP-DASH (TS 26.247 1), PSS (TS 26.234 2), MBMS (TS 26.346 3), M

31、TSI (TS 26.114 4, including multi-stream multiparty video conferencing), MMS (TS 26.140 5), and IMS Messaging and Presence (TS 26.141 6). Then use cases on video enhancements for existing 3GPP multimedia services are discussed, including a discussion on potential codec solutions for each of the use

32、cases. To enable drawing conclusions, simulation conditions and simulation results for comparisons of different codecs and their configurations are provided. Performance is evaluated in typical 3GPP service environments taking into account bandwidth, quality and complexity. Based on the performance

33、results, conclusions are made in terms of recommendations for support of enhanced video capabilities for 3GPP multimedia services. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either spe
