ETSI TR 126 948 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 3GPDASH
(TS 26.247 [1]), PSS (TS 26.234 [2]), MBMS (TS 26.346 [3]), MTSI (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 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 results,
conclusions are made in terms of recommendations for support of enhanced video capabilities for 3GPP multimedia
services.
