ETSI ETSI TR 126 949 V15.0.0 (2018-07)63GPP TR 26.949 version 15.0.0 Release 151 Scope The scope of the present document is to support the generation of a technical specification which defines a limited set of operation points for TV services i
29、n order to enable a consistent service offering within 3GPP. For this purpose the present document collects relevant information from other organizations and summarizes and consolidates these findings. Additional 3GPP specific aspects on TV profiles (such as existing and emerging UE capabilities, de
30、livery enablers, or specific service aspects) are collected and put in context. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition n
