15、L ELECTROTECHNICAL COMMISSION _ MULTIMEDIA HOME SERVER SYSTEMS INTERCHANGEABLE VOLUME/FILE STRUCTURE ADAPTATION FOR BROADCASTING RECEIVERS Part 1: General description and architecture FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comp
16、rising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Stan
17、dards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this prep
18、aratory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organ
19、izations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form
20、of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretati
21、on by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regi
22、onal publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this pub
23、lication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect
24、 or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the co
25、rrect application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62328-1 has been prepared
26、 by IEC technical committee 100: Audio, video and multimedia systems and equipment. The text of this standard is based on the following documents: FDIS Report on voting 100/963A/FDIS 100/987/RVD Full information on the voting for the approval of this standard can be found in the report on voting ind

A bilingual version of this publication may be issued at a later date. 62328-1 IEC:2005(E) 5 INTRODUCTION Broadcas
30、t data in a transport stream can contain multiple associated objects. When that data is distributed on interchangeable storage media, for example, optical disks, the associated objects should be synchronized. Open distribution of the media requires that the data be adapted to a standardized volume a
31、nd file structure, which should conform to the existing basic volume and file structure. 6 62328-1 IEC:2005(E) MULTIMEDIA HOME SERVER SYSTEMS INTERCHANGEABLE VOLUME/FILE STRUCTURE ADAPTATION FOR BROADCASTING RECEIVERS Part 1: General description and architecture 1 Scope This part of IEC 62328 define
32、s the volume and file structure required for interchanging multimedia data of a home server/broadcasting receiver, which consists of an AV stream with multiple associated objects. This part of IEC 62328 specifies references, definitions, abbreviations, notation and bibliography that apply to this an
33、d the other three parts. It also specifies requirements, design considerations and content architecture. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the

43、 to 9. 6 Requirements 6.1 Overview of digital broadcasting Conversion from analogue broadcasting to digital broadcasting based on ISO/IEC 13818 (MPEG-2) is in progress in many countries. From the point of view of contents protection, recording of digital broadcasting contents requires circumspection
44、 and caution. A discussion about broadcast services and how to store them onto built-in storage media has begun. Another point of discussion is how other receivers in a house can access contents recorded by one receiver. It is expected that distribution of contents and metadata via communications ne
45、tworks, such as the Internet, will include access control data. This standard aims at the following recording formats. A format which does not need to be conscious of built-in and removable media on the application level in order that removable media can be used as an extension of the built-in stora
46、ge which has limited capacity. A format which records a digital broadcasting programme to a removable medium by one receiver and play the programme by another receiver while protecting a content and keeping compatibility between receivers using secure UDF. A format which can record contents distribu
47、ted via broadcasting networks or removable media. 6.2 Main target contents The primary target contents of this standard are contents the recording of which is permitted by copy control information but the recording directory to be stored of which is not specified. However, contents whose recording d
48、irectory is specified can also be recorded into this format with some restrictions. 62328-1 IEC:2005(E) 9 6.3 Security module A removable medium, which carries a physical tamper-resistant module for protecting license information, is recommended from the content protection point of view. 7 Design co
49、nsiderations 7.1 Relationship between country-specific CAS and this specification Digital broadcasting contents, especially on pay per view services, may be scrambled by CAS. Each country defined its own CAS. The CAS defined by one country may not be the same as one defined by another country. According to this recording format, the contents scrambled by CAS shall not be recorded. However, the c
