27、ints for TV services in 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 emergi
28、ng UE capabilities, delivery 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

45、cement Information TV TeleVision UHD Ultra-High Definition VoD Video on Demand VUI Video Usability Information 4 Background and Context 4.1 Introduction Linear TV services can be made available on 3GPP networks via MBMS 3 and PSS 2 user services (over RTP or 3GP-DASH 4). - 3GP-DASH aims at offering
46、the best quality of experience as possible by adapting to the UE capabilities and dynamically to the network conditions. Linear TV and on-demand services are already identified as major use cases for 3GP-DASH delivery format. - (e)MBMS user services offer the possibility to offload the network when
47、the same content is consumed simultaneously by many UEs. This typically happens when a large audience accesses the same content concurrently, such as a popular football match, the Olympic Games, a political debate, breaking news, etc. For this reason, the access to live broadcast TV services is a ma
48、jor use case for eMBMS. For traditional linear TV distribution, TV services accessed through Satellite, Digital Terrestrial TV (DTT), cable or IPTV obey to requirements on the video profiles to ensure a consistent quality of experience while accessing different channels within a TV bouquet. On-deman
49、d video services, via streaming or downloading, generally obey to the same requirements. Up to Release-12, 3GPP specifications are missing detailed definitions of distribution formats (such as spatial and temporal resolutions, aspect ratios, random access points, etc.) for which operators and service providers can provide guarantees in terms of quality of experience. Typically, 3GPP service specifications only define profiles and levels of video codecs. Therefore, additional requirements/guidelines
