ISO/IEC 13818-6:1998/Amd 1:2000 PDF

Overview

ISO/IEC 13818-6:1998/Amd 1:2000 is an important amendment to the ISO/IEC 13818-6 standard, which extends the generic coding of moving pictures and associated audio (MPEG-2) by incorporating additions to support data broadcasting. This amendment is specifically focused on enhancing the DSM-CC (Digital Storage Media Command and Control) extensions, enabling robust and flexible data broadcast capabilities.

Developed by the joint ISO/IEC technical committee JTC 1, Subcommittee SC 29, this amendment provides critical updates to the MPEG-2 Systems, facilitating the broadcasting of data alongside audio and video in digital television, interactive services, and multimedia applications.

Key Topics

• DSM-CC Extensions The amendment updates the DSM-CC module definitions to better support data broadcasting. Key enhancements include changes to module size semantics and message re-assembly within MPEG-2 Transport Streams.

• Section Syntax Enhancements New section types, such as DSMCC_section and DSMCC_Addressable_section, are introduced with additional semantics compatible with the generic ISO/IEC 13818-1:2000 section syntax. This compatibility ensures that existing MPEG-2 decoders can handle DSM-CC extensions seamlessly.

• Addressable Sections A new DSMCC_Addressable_section format allows sending encapsulated datagrams to specific devices or groups by embedding a 48-bit deviceId within the section header. This supports device-targeted data delivery with scrambling options for payload and addresses, enhancing security and functionality.

• Scrambling and Error Detection The amendment defines payload and address scrambling controls with user-defined scrambling methods. It also introduces both CRC-32 error detection and a 32-bit checksum option for data integrity verification, providing flexibility for different network environments.

• Table and Stream Type Revisions Updates to table identifiers and stream type assignments better classify multi-protocol encapsulation, DSM-CC messages, stream descriptors, and private data, optimizing transport stream handling for data broadcasting.

Applications

ISO/IEC 13818-6:1998/Amd 1:2000 is crucial for:

• Digital Television Broadcasting Enables broadcasters to transmit interactive applications, software updates, electronic program guides, and multimedia content alongside traditional audio and video streams.

• Multimedia and Interactive Services Supports delivery and targeted addressing of multimedia data, allowing interactive content tailored to specific receivers or groups, enhancing user engagement and service customization.

• Data Broadcasting Networks Provides a standardized framework to support data broadcasting over MPEG-2 transport streams, useful in satellite, cable, and terrestrial broadcast infrastructures.

• Set-Top Boxes and Receivers Implements device-specific data reception and processing by embedding deviceId for address filtering, improving functionality in consumer electronics.

Related Standards

• ISO/IEC 13818-1:2000 MPEG-2 Systems – Defines the base transport stream and table syntax used in the amendment for re-assembly and signaling.

• ISO/IEC 8802-2 and 8802-1a Standards governing Logical Link Control (LLC) and SubNetwork Attachment Point (SNAP), referenced for encapsulating datagrams within DSM-CC.

• ITU-T Rec. H.222.0 Related MPEG-2 standards used for defining table IDs and stream types, offering interoperability for multimedia transport.

By adopting ISO/IEC 13818-6:1998/Amd 1:2000, organizations can enhance MPEG-2 broadcast systems with advanced data broadcasting support, improving service delivery efficiency and enabling new interactive multimedia applications that meet international standards.
