24、nsport 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 and file structu

25、re, which should conform to the existing basic volume and file structure.

26、 description and architecture 1 Scope This part of IEC 62328 defines 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, definiti

27、ons, abbreviations, notation and bibliography that apply to this and 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.

38、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 and caution. A discussion about broadcast services and how to store t

39、hem 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 networks, such as the Internet, will include access control data. This s

40、tandard 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 storage which has limited capacity. A format which records a digital broadc

41、asting 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 distributed via broadcasting networks or removable media. 6.2 Main target cont

42、ents 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 directory is specified can also be recorded into this format with some

43、restrictions. Licensed Copy: Wang Bin, na, Tue Apr 25 02:05:37 BST 2006, Uncontrolled Copy, (c) BSIEN 62328-1:2005 8 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.

44、7 Design considerations 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 cou

45、ntry. According to this recording format, the contents scrambled by CAS shall not be recorded. However, the contents descrambled in a receiver may be encrypted and stored. 7.2 Broadcasting system specific structure A digital broadcasting system defined by one country may be different from that of an

46、other country. The digital broadcasting system in the United States has been developed in the ATSC. In Europe, the digital broadcasting system has been developed in the DVB project. In Japan, the digital broadcasting system, which is called ISDB, has been developed in the ARIB. In this specification

47、, the differences between digital broadcasting systems are absorbed as much as possible. Generic recording structure is specified in IEC 62328-2. The broadcasting system specific structure in Japan is specified in IEC 62328-3. Another broadcasting system specific structure may be specified in the fu
