Content for TR 26.903 Word version: 17.0.0
1 Scope p. 6
The present document provides an analysis of the future video capability requirements of streaming and multicast/broadcast services. The purpose of this document is two-fold. On the one hand, it studies the options to upgrade the minimal requirements for video reception and decoding. On the other hand, it studies use cases for support of more advanced UEs. The ultimate target of this study item is to recommend solutions for efficiently providing video support commensurate with UE and user capabilities and needs in PSS and MBMS services.
