Overview
IEC 62328-3:2005 is part of the IEC 62328 series for multimedia home server systems and defines the interchangeable volume/file structure adaptation specifically for ISDB broadcasting receivers. The standard specifies how recorded audiovisual (AV) streams and their associated objects (metadata, component descriptors, program information) must be organized on storage volumes to enable reliable interchange between home servers and broadcasting receivers. It is the ISDB-specific recording structure complementing the general architecture (Part 1) and general recording rules (Part 2).
Key topics
- Volume and file structure: required directory and file layout for recorded programs to support interoperability between devices.
- Metadata handling: organization of MetaDataTable streams, MDE (meta data entry) formats and TYPE1/TYPE2 MDE interpretations.
- Program information files: PROGxxxx.PIF and associated structures for storing programme general information and descriptors.
- Component and component-group descriptions: formats for audio/video/data components, grouping, and search pointers.
- Stream-type dependent data: rules for video, audio and data modes and their associated stream descriptors.
- Partial TS / PSI‑SI mapping: guidance on partial transport stream format and mapping tables (Annex A).
- Country- or system-specific annexes: Japanese digital TV specifics (Annex B), D-VHS particulars (Annex C) and coexistence rules with domestic services (Annex D - normative).
- Character sets, notation and normative references: character set fields, notation conventions and referenced standards necessary for correct implementation.
Applications
- Enables interoperability between ISDB set‑top boxes, digital TV receivers and home media servers for recorded-program exchange, playback and content management.
- Provides a blueprint for firmware and middleware developers implementing recording, file-system layout and metadata handling in consumer electronics.
- Used by manufacturers of broadcasting receivers, home servers, and DVRs to ensure recorded content can be read/written across devices.
- Helps system integrators and test labs create conformance tests and validation procedures for ISDB recording implementations.
- Useful for broadcasters and service providers wanting consistent metadata packaging for recorded content distribution.
Who should use this standard
- Device manufacturers (set-top boxes, home servers, PVR/DVR vendors)
- Firmware and middleware developers
- Interoperability test labs and certification bodies
- Broadcasters and system integrators working with ISDB deployments
