Introduction Dynamic and Interactive Multimedia Scenes (DIMS) is a dynamic, interactive, scene-based media system which enables display and interactive control of multimedia data such as audio, video, graphics, images a

30、nd text. It ranges from a movie enriched with vector graphic overlays and interactivity (possibly enhanced with closed captions), to complex multi-step services with fluid interaction/interactivity and different media types at each step. The demand for such Rich Media service is increasing at a high

31、 pace, spurred by the development of the next generation mobile infrastructure and the generalization of TV content to new mobile environments. In the case of a video portal application, subscribers can watch TV, video and audio enriched with additional data (graphics, text, images) in streaming, pr

32、ogressive download or offline mode. DIMS provides a convenient and natural way to browse rich-media services, a web-like access (content available in less than three clicks, easy discovery, no learning curve), a permanent refresh of content through dynamic updates available on the fly and decreasing

33、 latency by allowing the visualization of data as soon as possible. Content can be synchronized up to a frame-accurate basis (e.g. to ensure content providers and operators that voting will start and stop at a precise time during a vote within an interactive show or to allow karaoke text flows). ETS

34、I ETSI TS 126 142 V15.0.0 (2018-07)63GPP TS 26.142 version 15.0.0 Release 151 Scope DIMS defines a dynamic rich-media system, including a media type, its packaging, delivery, and interaction with the local terminal, user, and other local and remote sub-systems. Enhanced end-user experiences are prov

35、ided by the coordinated management and synchronization of media and events, combined with end-user interaction. The DIMS media type can be used as a generic media type, allowing creating dynamic interactive rich-media services and can also benefit, or be used in association with other media types (e

36、.g.: audio codecs, video codecs, XHTML browser, etc.). 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, et
