SIST EN 300 401 V1.3.2:2003 is the Slovenian standard identical to EN 300 401 Version 1.3.2 for Digital Audio Broadcasting (DAB). It specifies the DAB broadcasting system for mobile, portable and fixed receivers, including the transmitted signal, audio coding, multiplexing, channel coding, modulation and service information for audio and data services. In practice, broadcasters, network planners and equipment manufacturers use it to build interoperable DAB services and receivers.
What does SIST EN 300 401 V1.3.2:2003 specify?
SIST EN 300 401 V1.3.2:2003 establishes the DAB broadcasting standard for terrestrial or satellite transmitters in the VHF/UHF bands, and for distribution through cable networks. It covers the signal on air, the service structure, and the way audio and data are carried.
The scope also states that receiver design aspects and hardware implementation considerations are outside the document.
The document is organized into clauses 1 to 15, followed by annexes A to E.
| Annex | Covers |
|---|---|
| A | Main characteristics of the audio coding system |
| B | Audio decoding |
| C | Audio encoding |
| D | Multiplex re-configuration |
| E | Calculation of the CRC word |
What are the key requirements of SIST EN 300 401 V1.3.2:2003?
SIST EN 300 401 V1.3.2:2003 is built around a small set of transport, coding and signalling rules that let a receiver find, identify and decode services.
- Clause 5 defines two transport paths: the Fast Information Channel (FIC) and the Main Service Channel (MSC). The FIC carries Multiplex Configuration Information (MCI), Service Information (SI), Conditional Access (CA) data and the Fast Information Data Channel (FIDC); the MSC carries the audio and data service components. This matters because a receiver must read the FIC first to know how to decode the MSC.
- Clause 6 uses MCI to describe the ensemble structure, the sub-channels, the services, the service components and the links between them. It also supports multiplex re-configuration, so services can change without losing continuity.
- Clause 7 specifies DAB audio coding with MPEG Audio Layer II, using ISO/IEC 11172-3 at 48 kHz and ISO/IEC 13818-3 at 24 kHz. It also defines audio modes and Programme Associated Data (PAD), including Fixed PAD (F-PAD) and Extended PAD (X-PAD), which carry items such as text and programme-related information.
- Clause 8 defines Service Information such as labels, Date and Time, Programme Number, Programme Type, announcements, Frequency Information, Transmitter Identification Information (TII), and links to FM and AM services. In practice, this is the metadata a receiver uses for browsing, display and service linking.
- Clause 9 defines Conditional Access, including scrambling and descrambling, Entitlement Checking Messages (ECM) and Entitlement Management Messages (EMM). This is the part used when access to a service or component must be restricted.
- Clauses 10 to 12 define energy dispersal, convolutional coding and time interleaving. The document distinguishes Unequal Error Protection (UEP) and Equal Error Protection (EEP), which lets system designers match protection to audio or data needs.
- Clauses 13 to 15 define the Common Interleaved Frame (CIF), the DAB transmission signal and the radiofrequency characteristics. The document also defines four transmission modes for different network and frequency conditions.
What terms does SIST EN 300 401 V1.3.2:2003 define?
- Fast Information Channel (FIC) - the channel that carries control information needed to interpret the multiplex.
- Main Service Channel (MSC) - the channel that carries the audio and data service components.
- Multiplex Configuration Information (MCI) - the information that describes how the DAB multiplex is organized.
- Common Interleaved Frame (CIF) - the common MSC data structure used across transmission modes.
- Programme Associated Data (PAD) - information at the end of the audio frame that is related to the audio content and timing.
- Conditional Access (CA) - the mechanism used to restrict service access to authorized users.
- Single Frequency Network (SFN) - a network of transmitters sharing the same radio frequency for wide-area coverage.
Who uses SIST EN 300 401 V1.3.2:2003?
SIST EN 300 401 V1.3.2:2003 is used by broadcasting organizations, telecommunications providers and professional and consumer electronics companies involved in DAB services. It is relevant to engineers who design encoders, multiplexers, transmitters and receivers, and to planners who organize ensembles, services and SFN coverage. It also matters to product and quality teams that need to check service information, audio transport, PAD, CA and RF behaviour.
What changed in SIST EN 300 401 V1.3.2:2003 from the previous edition?
SIST EN 300 401 V1.3.2:2003 is a revision of ETS 300 401 Ed 2. The foreword states that it adds refinements in these areas:
- database management signalling for certain Service Information FIGs
- use of packet mode without data groups
- user application signalling
- a universal character set
- global and ensemble regions signalling
Which standards are used with SIST EN 300 401 V1.3.2:2003?
SIST EN 300 401 V1.3.2:2003 references several standards that supply coding, signalling or background rules:
- ISO/IEC 11172-3 and ISO/IEC 13818-3 - the MPEG Audio Layer II audio coding referenced for DAB audio.
- ITU-T Recommendation X.25 - the CRC polynomial basis used for CRC words.
- ISO/IEC 10646-1 - the UTF-8 character set used for labels.
- EN 50067 - RDS for FM service cross-referencing.
- EN 301 234, ES 201 735, TS 101 756 and TS 101 759 - related DAB protocols for MOT, IP datagram tunnelling, registered tables and transparent data channels.
- ITU-R Recommendations BS.774 and BO.789 - service requirements that the DAB system is based on.
What does the SIST EN 300 401 V1.3.2:2003 document contain?
SIST EN 300 401 V1.3.2:2003 contains a conceptual emission block diagram, transmission frame and packet structures, and C-like bitstream syntax descriptions for the audio and data fields. It also includes tables for transport and transmission modes, service and packet structures, and RF characteristics.
Annex B gives audio decoding procedures, Annex C gives audio encoding guidance, and Annex E gives the CRC word calculation procedure. Annex A summarizes the audio coding characteristics, while Annex D covers multiplex re-configuration.
