Introduction In the 3GPP context, service interactivity refers to a class of
33、 features that enables user engagement during the consumption of a streaming or downloaded service/content on the UE, distributed over broadcast or unicast bearers. Examples of services/contents which may offer interactivity capabilities include linear/live TV services, video-on-demand programs, and
34、 pre-downloaded media content which a user can consume later on, in a time-shifted manner. For video content, for example a TV program or an advertisement, service interactivity facilitates active watching (as opposed to passive viewing) by allowing the end-user to actively interact and participate
35、with the presented content. In the context of services delivered over PSS or MBMS, different forms of service interactivity may be possible, for example: - Voting for a favourite performer, - Dynamic quizzes, surveys, elections, - Rating of a live event during a program, - Web access to additional i
36、nformation related to main content, - Online chats about actors in TV episode or movie, - Interactive advertisements, - eCommerce and online shopping, and many others. Personalized and interactive service capabilities in 3GPP streaming and download services, via unicast and/or broadcast delivery, ca
37、n drive higher end-user satisfaction and loyalty to the service operator, i.e., create greater “stickiness“ of the operators service offerings such as linear TV programs, live sports events and downloadable multimedia content. It could also enable the operator to further monetize streaming services
38、(especially when distributed over MBMS) by, for example: - Increasing the subscriber base through premium contextual service offerings. - Supporting on-demand information or targeted advertising via simple user interaction such as click-to-call, click-to-SMS, or click-to-Web access. ETSI ETSI TR 126
39、 953 V15.0.0 (2018-07)63GPP TR 26.953 version 15.0.0 Release 15- Driving greater cellular airtime or data volume usage associated with end-user initiated traffic pertaining to interactivity, the fees for which may be borne by a 3rd-party entity such as an advertiser or content provider, as opposed t
40、o the subscriber. Service interactivity in 3GPP streaming and download service comprises application/presentation layer functionality, pertaining to user interface and user experience afforded by the interactivity feature, as well as a transport/signaling component, responsible for the discovery, sy
41、nchronization and delivery of application and media content that define the interactivity experience. While the definition of the former, application/presentation layer aspects is largely outside the scope of 3GPP specification, delivery and signaling functions for enabling interactivity are fully w
42、ithin 3GPPs domain. Many of the tools required to signal and deliver functional components of interactive services may already exist in 3GPP PSS and MBMS specifications, but need to be clearly understood, leveraged, and possibly extended to fully support service interactivity. The present document e
43、xamines major use cases for service interactivity in 3GPP streaming and download services, and associated requirements and potential gaps in existing PSS and MBMS service layer specifications for interactivity support. It surveys service interactivity functionality specified in broadcast TV standard
44、s, as a reference point for potential emulation by, or differentiation from, 3GPP-defined mechanisms. It concludes by identifying functional gaps in MBMS and PSS specifications to support the identified recommended requirements regarding interactivity, and summarizes the necessary capabilities to fu
45、lfill those gaps. ETSI ETSI TR 126 953 V15.0.0 (2018-07)73GPP TR 26.953 version 15.0.0 Release 151 Scope The present document covers the study of interactivity support for 3GPP-based streaming and download services, in the context of services delivery over MBMS and PSS. Topical areas addressed inclu
46、de the following: - Use cases and associated assumptions, recommended requirements and gap analyses on the operation of and means to support interactivity capabilities in streaming and download services. - End-to-end architecture and functional component models, with emphasis on unicast and broadcas
47、t DASH services. - Differentiation between application/presentation level and transport/service layer functions in support of interactive services. - Overview of service interactivity mechanisms in terrestrial broadcast TV services, as defined in DVB and ATSC specifications. - Notification mechanism
48、s to activate interactive events, either pre-scheduled or to occur dynamically and unpredictably, at precise times during consumption of a main service or program. - Functional gaps in current MBMS and PSS application/service layer specifications to support desired interactivity functions. - Measure
49、ment and reporting of the consumption of interactive features. 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 number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies.
