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

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

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
