Foreword This Technical
27、 Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBU/ETSI JTC Broadcast was established in 1
28、990 to co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the standardization of radio and television receivers. T
29、he EBU is a professional association of broadcasting organizations whose work includes the co-ordination of its members activities in the technical, legal, programme-making and programme-exchange domains. The EBU has active members in about 60 countries in the European broadcasting area; its headqua

31、, content owners and others committed to designing global standards for the delivery of digital television and data services. DVB fosters market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and consumers. DVB standards cover all aspects of digita
32、l television from transmission through interfacing, conditional access and interactivity for digital video, audio and data. The consortium came together in 1993 to provide global standardization, interoperability and future proof specifications. The normative XML schemas referenced by the present do

35、 1 Scope The present document defines a framework for the signalling and carriage of interactive applications or services in broadcast and broadband networks. This framework covers: Signalling interactive applications or services in both classical broadcast networks and broadband networks. Distribut
36、ing the files of interactive applications or services through either classical broadcast networks or broadband networks. Synchronizing interactive applications or services to video or audio content distributed through classical broadcast networks or broadband networks. Referencing video, audio or su
37、btitle content distributed through classical broadcast networks or broadband networks from interactive applications or services. The present document is independent of any particular technology for interactive applications or services. It is intended to be referenced by organizations defining how in
38、teractive applications or services are to be deployed and not used as a stand-alone document in its own right. It is expected that those organizations will make a selection appropriate for their market or deployment from among the functionality defined here. The use of “shall“, “should“ and similar
39、terms in the present document is intended to apply only if the particular feature is used and not to imply that the feature itself is mandatory. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-spe
40、cific. For specific references, only the cited version applies. For non-specific references, the latest version of the referenced document (including any amendments) applies.
