Foreword This Technical 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:
20、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 Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the stand
21、ardization of radio and television receivers. The 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
22、 in the European broadcasting area; its headquarters is in Geneva.

23、he television industry. Its aim is to establish the framework for the introduction of MPEG-2 based digital television services. Now comprising over 200 organizations from more than 25 countries around the world, DVB fosters market-led systems, which meet the real needs, and economic circumstances, o

ETSI ETSI TS 102 816 V1.1.1 (2007-09) 7 1 Scope The present document defines the extension to the MHP specification supporting the recording of digital television content. It includes the scheduling of recordings, the management of sche
28、duled recordings, the playback of completed recordings and the management of completed recordings. It includes the recording and playback of MHP applications that form part of the digital television content being recorded. It includes access to the metadata and content resolution mechanisms defined
29、by TV-Anytime. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

44、e original document is shown underlined and text that the present document removes from the original document is shown with strike-through. The present document uses the terminology that something “shall be recorded“, “should be recorded“, “shall not be recorded“ or “should not be recorded“. This is
45、 a convention for the sake of brevity and in all cases, implementations are allowed to record items that “shall not be recorded“ and discard them during playback. The term “shall not be recorded“ is simply shorter than “shall not be recorded, or if recorded, shall be discarded during playback“ and t
46、he latter is what is meant. 5 Basic Architecture 5.1 Relationship with MHP and GEM Specifications Implementations of the present document shall additionally implement all mandatory requirements of either ES 201 812 1 or TS 102 812 2. NOTE: Future versions of the present document may remove ES 201 81
47、2 1 from the above and require implementation of all mandatory requirements of TS 102 812 2. All normative clauses of TS 102 817 6 shall apply regardless of whether the clause is explicitly mentioned below. 5.2 Overview (informative) Figure 1 shows an overview of the architecture assumed by the pres
