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
