The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG wit
26、h an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TSG approved document under change control. y the second digit is incremented for
27、all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction Dynamic and Interactive Multimedia Scenes (DIMS) is a dynamic, interactive, scene-based media system whi
28、ch enables display and interactive control of multimedia data such as audio, video, graphics, images and 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
29、and different media types at each step. The demand for such Rich Media service is increasing at a high 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
30、 can watch TV, video and audio enriched with additional data (graphics, text, images) in streaming, progressive 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 learn
31、ing curve), a permanent refresh of content through dynamic updates available on the fly and decreasing 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 an
32、d stop at a precise time during a vote within an interactive show or to allow karaoke text flows). ETSI ETSI TS 126 142 V14.0.0 (2017-04)63GPP TS 26.142 version 14.0.0 Release 141 Scope DIMS defines a dynamic rich-media system, including a media type, its packaging, delivery, and interaction with th
33、e local terminal, user, and other local and remote sub-systems. Enhanced end-user experiences are provided 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 int
34、eractive rich-media services and can also benefit, or be used in association with other media types (e.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.
