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 Broadcast became
31、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 in the t

34、January 2004 ETSI 6 ETSI EN 300 231 VI .3.1 (2003-04) I n t rod uct ion Programme Delivery Control (PDC) is a data broadcasting system which carries programme-related information for exploitation by suitably-equipped domestic video recorders. In its simplest application the programmes chosen by the
35、viewer will be recorded by such recorders in their entirety, even if the transmission time is different from that published in the programme guide (for example owing to the over-run of a previous programme). More advanced applications may, for example, permit recording to be suspended and resumed in
36、 synchronism with breaks in programme transmission, such as may occur during a feature film in the event of film breakage. The PDC system functions may be considered in two parts. Preselection functions deliver information about the programmes to the domestic recorder; this information may be carrie
37、d via print media or via Teletext. In the latter case the user may make his selection of programmes by viewing the Teletext programme guide pages and, by the use of his remote-control, positions a cursor adjacent to the wanted programme. At the touch of a button he confirms his choice and the video
38、recorder stores his requirement. If the video recorder does not incorporate full Teletext decoder functionality, the preselection information has to be keyed in manually, in the more conventional way. The Recording-control function depends on the establishment of a match between the viewers preselec
39、tion and a programme label transmitted by the broadcaster with each programme, thereby triggering the start and end of the recording process in synchronism with the actual transmission time of the programme. The Programme Delivery Control (PDC) system specification is the result of several years of
40、studies by the EBU in close collaboration with European industry. In accordance with the wishes of the European broadcasters, expressed in their replies to an EBU enquiry, the preselection and recording control functions of the PDC system have been designed mainly around the structure of EN 300 706
41、2 Teletext. The starting point for the development process was the Video Programming System (VPS) in Germany. The system has been designed to be comprehensive in the facilities it offers, and applicable to the whole of Europe. It will accommodate all future requirements foreseen by the specialists i
42、nvolved, including those deriving from the expansion of international television services (e.g. direct broadcasting satellite services). Downwards compatibility is assured with systems already implemented and optional methods are provided for performing particular functions where the preferred metho
43、ds are not appropriate. To assure the long-term flexibility of the PDC system, the specialists recommend that where EN 300 706 2 Teletext is in operation new PDC services should provide both the recording control function and the programme preselection function by means of data carried in extension
44、data packets. For recording control this approach offers the most efficient use of the resource represented by the vertical blanking interval of the television signal; for preselection it allows the Teletext editor greater freedom in the layout of Teletext programme guide pages. A further advantage
45、is that all PDC data are acquired by a common process at the receiver. Although the transport of preselection data by Teletext extension packets is preferred, it is nevertheless recommend that all decoders should also be able to process preselection data sent within the displayable Teletext page. Wh
46、ere no a-priori restriction applies, the preferred method for sending recording control data is in EN 300 706 2 Teletext extension data packets of type 8/30 format 2. Other methods nonetheless remain in the present specification; where these concern services already implemented in certain countries
47、they are considered in the main text, whilst others are considered in the annexes. Experience with the services already implemented has highlighted the need for clear operational rules, and a Code of Practice for Broadcasters has been included to ensure that the intended response is obtained at the
48、receiver. It will also be necessary to arrange for the orderly introduction of any new features (see note 1) which the system is potentially able to deliver, or any further enhancements, as they are specified. The specialists therefore plan to continue their collaboration with industry as the PDC sy
49、stem is implemented and introduced into service. NOTE 1 : Further enhancements are under study. Considering that broadcasters may not only wish to modiSl programme schedules at short notice but also are required to generate and transmit the real-time commands to VCRs it is essential that both operations are under their close control. NOTE 2: The term “PDC“ is used here as a technical description of the system and follows the current ITU-R terminology. Trade names for services provided within the specification of PDC include VPS, VPT (Vi
