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.

ETSI ETSI TS 102 822-3-2 V1.6.1 (2010-07) 7Introduction The present document is based on a submission by the TV-Anytime forum (http:/www.TV-Anytime.org). “TV-Anytime“ (TVA) is a full and synchronized set of specifications established by the TV-Anytime Forum. TVA featur
35、es enable the search, selection, acquisition and rightful use of content on local and/or remote personal storage systems from both broadcast and online services. TS 102 822-1 7 and TS 102 822-2 8 set the context and system architecture in which the standards for Metadata, Content referencing, Bi-dir
36、ectional metadata and Metadata protection are to be implemented in the TV-Anytime environment. TS 102 822-1 7 provides benchmark business models against which the TV-Anytime system architecture is evaluated to ensure that the specification enable key business applications. TS 102 822-2 8 presents th
37、e TV-Anytime System Architecture. These two documents are placed ahead of the others for their obvious introductory value. Note that these first two documents are largely informative, while the remainder of the series is normative. The features are supported and enabled by the specifications for Met

39、and Protection (TS 102 822-7 18), Interchange Data Format (TS 102 822-8 19) and Remote Programming (TS 102 822-9 20). All Phase 1 and 2 Features listed in TS 102 822-1 7 are enabled by the normative TV-Anytime tools specifications. The metadata specifications TS 102 822-3-1 9, TS 102 822-3-310, TS 1

The present document introduces new network agnostic technologies used to process these descriptions for the purpose of transmission in a unidirectional e
41、nvironment. ETSI ETSI TS 102 822-3-2 V1.6.1 (2010-07) 81 Scope The present document is one in a series of Technical Specification documents produced by the TV-Anytime Forum. These documents establish the fundamental specifications for the services, systems and devices that will conform to the TV-Any
42、time standard, to a level of detail that is implementable for compliant products and services. TS 102 822-1 7 and TS 102 822-2 8 set the context and system architecture in which the standards for Metadata, Content referencing, Bi-directional metadata and Metadata protection are to be implemented in
43、the TV-Anytime environment. TS 102 822-1 7 provides benchmark business models against which the TV-Anytime system architecture is evaluated to ensure that the specification enable key business applications. TS 102 822-2 8 presents the TV-Anytime System Architecture. These first two documents are lar
44、gely informative, while the remainder of the series is normative. Although each in the series of documents is intended to stand alone, a complete and coherent sense of the TV-Anytime system standard can be gathered by reading all the specification documents in numerical order.

The present document introduces new net
48、work agnostic technologies used to process these descriptions for the purpose of transmission in a unidirectional environment. The actual format and semantics of the delivery layer are specific to the particular uni-directional environment in which TV-Anytime is deployed. However, in order for the e
49、ncoding and encapsulation mechanisms to operate as intended the delivery layer must meet certain requirements. These normative requirements are defined in annex B of TS 102 822-2 8.
