Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU)
37、, Comit 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 B
38、roadcast 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 act
39、ivities 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.

40、22 717 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 service
41、s. DVB 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.
42、 The consortium came together in 1993 to provide global standardisation, interoperability and future proof specifications. Introduction Phase 1 of the work of the TV-Anytime Forum (TVAF) has defined key technologies for personal digital recorders (PDRs). DVB has adopted these specifications as the b
43、asis of support for PDRs on DVB networks. The present document provides an implementation of the TV-Anytime phase one on DVB transport streams in a way that enhances and extends existing DVB functionality. ETSI ETSI TS 102 323 V1.5.1 (2012-01)81 Scope The present document describes a method of suppo
44、rting personal digital recorders (PDRs) in DVB broadcast networks. It was developed to fulfil the commercial requirements for supporting PDRs. The data types and protocols defined in the present document are based upon TV-Anytime phase 1 specifications 3, 4, 5 and 6. 2 References References are eith
45、er specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies. Referenced documents which a
