When that data is distributed on interchangeable storage media, for exa

23、mple, 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 structure, which should conform to the existing basic volume and file structure. 5 EN 62328-1:2005 MULTIMEDIA HOME SERVER SYSTEMS INT

24、ERCHANGEABLE VOLUME/FILE STRUCTURE ADAPTATION FOR BROADCASTING RECEIVERS Part 1: General 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

25、 with multiple associated objects. This part of IEC 62328 specifies references, definitions, 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 ref

36、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 them onto built-in storage media has begun. Another point of discussion is how other

37、 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 standard aims at the following recording formats. A format which does not need to be

38、 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 broadcasting programme to a removable medium by one receiver and play the programme by an

39、other 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 contents The primary target contents of this standard are contents the recording of whi

40、ch 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 restrictions. EN 62328-1:2005 8 6.3 Security module A removable medium, which carri

41、es a physical tamper-resistant module for protecting license information, is recommended from the content protection point of view. 7 Design considerations 7.1 Relationship between country-specific CAS and this specification Digital broadcasting contents, especially on pay per view services, may be

42、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 contents descrambled in a receiver may be encrypted and stor

43、ed. 7.2 Broadcasting system specific structure A digital broadcasting system defined by one country may be different from that of another 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

44、 DVB project. In Japan, the digital broadcasting system, which is called ISDB, has been developed in the ARIB. In this specification, the differences between digital broadcasting systems are absorbed as much as possible. Generic recording structure is specified in IEC 62328-2. The broadcasting syste

45、m specific structure in Japan is specified in IEC 62328-3. Another broadcasting system specific structure may be specified in the future IEC 62328-41. 8 Content architecture 8.1 Basic content architecture Programme (Entity)Programme reference (Link) MetaData_Table ExtractionReferenceProgramme refere

47、s the basic architecture of this specification. A programme (entity) consists of a recorded TVRS partial TS and its related information. A unit of a programme may correspond to a TV programme. Programme reference (link) is a pointer, which references all or a part of TVRS partial TS in a programme.

48、Programme group is a set of programme references or programme reference groups. MetaData_Table is a database which enables users to retrieve desired TV programmes from a storage medium. Metadata in the programme (entity) may be extracted to make a MetaData_Table. MetaData_Table may be used for makin

49、g a programme reference group. Examples of how to use programme references and programme reference groups are described in Annex A. 8.2 Basic rule and policy 8.2.1 Recording rules If the concept of event exists in broadcasting/transporting TS, the recording unit which is called programme in this specification shall consist of only one event. Otherwise, partial TS via digital interface may be the case, the recording unit shall be specified by an actio
