Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit

12、 Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcas

13、t became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the standardization of radio and television receivers. The EBU is a professional association of broadcasting organizations whose work includes the co-ordination of its members activities

14、 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 headquarters is in Geneva.

15、24 81 The Digital Video Broadcasting Project (DVB) is an industry-led consortium of broadcasters, manufacturers, network operators, software developers, regulatory bodies, content owners and others committed to designing global standards for the delivery of digital television and data services. DVB

16、fosters market driven solutions that meet the needs and economic circumstances of broadcast industry stakeholders and consumers. DVB standards cover all aspects of digital television from transmission through interfacing, conditional access and interactivity for digital video, audio and data. The co

17、nsortium came together in 1993 to provide global standardisation, interoperability and future proof specifications. ETSI ETSI TS 102 539 V1.3.1 (2010-04)61 Scope The present document specifies the signalling and the transport of TV-Anytime information over an always-on bi-directional IP network. The

18、 specification allows for metadata describing Live Media Broadcast, Content on Demand and Content Download Services delivered over any type of network using DVB specifications (e.g. DVB-T, DVB-S, DVB-IPTV). It can be used to develop a Broadband Content Guide, i.e. a content guide that is delivered o

19、ver an always-on bi-directional IP network.

Content on Demand (CoD): program provided at the request of the end user for direct consumption (real-time streaming) content provider: entity that owns or is licensed to sell content or content assets Delivery Network (DN): network co

32、nnecting the Delivery Network Gateway (DNG) and service providers Delivery Network Gateway (DNG): device that is connected to one or multiple delivery networks and one or multiple home network segments DVB-IPTV service: one or more programmes under the control of a service provider delivered over IP

40、ed in TS 102 034 4 shall support the container-based mechanism, both via multicast and unicast. It may additionally support the query mechanism. On all networks there shall be at least one BCG provider that supports the container based download mechanism. Additionally, this provider may support the

41、query mechanism. For clarification, the query mechanism is optional for both Service Providers and HNEDs. The container based download mechanism uses the Data Delivery Unit, as specified in clause 4.1.1.3, delivered via the mechanisms specified in clause 4.2. The query mechanism is specified in clau

42、se 4.3. 4.1 Container-Based Delivery 4.1.1 Definitions 4.1.1.1 Container A container shall carry either a RNT, one or more CRI structures or metadata. Each container is distinguished by a unique identifier, which is the container_id. Table 1 shows the clauses in the present document where the contai

43、ner format, according to each type of data carried, is defined.

44、ner carries determines the scope and format of the structure values. 4.1.1.2 Compression wrapper The compression_wrapper allows a container to be carried in a compressed or uncompressed format. The syntax of the compression_wrapper is defined in table 21, clause 7.3.1.5 of TS 102 323 1. The compress

45、ion_wrapper shall always be present, whether or not the container is compressed. The semantics of the fields of table 21, clause 7.3.1.5 of TS 102 323 1 are modified as follows: container(): See clause 4.1.1.1 for the definition of the container structure.
