This document defines a storage and delivery format for metadata for energy-efficient decoding, encoding, presentation, and selection of media (green metadata) as defined in ISO/IEC 23001-11. The green metadata are timed metadata which can be associated with other tracks in the ISO Base Media File Format. Timed metadata such as power consumption information and their metrics are defined in this document for carriage in files based on ISO/IEC 14496-12. In the context of DASH delivery, the green metadata representations and their association to the media representations are also defined using the signalling mechanisms specified in ISO/IEC 23009-1:2022 and ISO/IEC 23009-3[1]. These metadata can be used for multiple purposes, including optimizing power consumption during playback and supporting dynamic adaptive streaming.

This document specifies the system layer of the coding. It was developed principally to support the combination of the video and audio coding methods defined in Parts 2 and 3 of ISO/IEC 13818. The system layer supports six basic functions: 1) the synchronization of multiple compressed streams on decoding; 2) the interleaving of multiple compressed streams into a single stream; 3) the initialization of buffering for decoding start up; 4) continuous buffer management; 5) time identification; 6) multiplexing and signalling of various components in a system stream. A Rec. ITU-T H.222.0 | ISO/IEC 13818-1 multiplexed bit stream is either a transport stream or a program stream. Both streams are constructed from PES packets and packets containing other necessary information. Both stream types support multiplexing of video and audio compressed streams from one program with a common time base. The transport stream additionally supports the multiplexing of video and audio compressed streams from multiple programs with independent time bases. For almost error-free environments the program stream is generally more appropriate, supporting software processing of program information. The transport stream is more suitable for use in environments where errors are likely. A Rec. ITU-T H.222.0 | ISO/IEC 13818-1 multiplexed bit stream, whether a transport stream or a program stream, is constructed in two layers: the outermost layer is the system layer, and the innermost is the compression layer. The system layer provides the functions necessary for using one or more compressed data streams in a system. The video and audio parts of this Specification define the compression coding layer for audio and video data. Coding of other types of data is not defined by this Specification, but is supported by the system layer provided that the other types of data adhere to the constraints defined in 2.7.

This document describes the desired joint behaviour of MPEG-4 Systems (MPEG-4 File Format) and MPEG-4 Audio codecs. It is desired that MPEG-4 Audio encoders and decoders permit finite length signals to be encoded to a file (particularly MPEG-4 files) and decoded again to obtain the identical signal, subject to codec distortions. This enables the use of audio in systems implementations (particularly MPEG-4 Systems), perhaps with other media such as video, in a deterministic fashion. Most importantly, the decoded signal has nothing “extra” at the beginning or “missing” at the end. This permits: a) an exact "round trip" from raw audio to encoded file back to raw audio (excepting encoding artefacts); b) predictable synchronization between audio and other media such as video; c) correct behaviour when performing random access as well as when starting at the beginning of a stream; d) identical behaviour when edits are applied in the raw domain and the encoded domain (excepting encoding artefacts). It is also expected that there be predictable interoperability between encoders (as represented by files) and decoders. There are two kinds of audio "offsets" (or "delay" in the context of transmission): those that are result from the encoding process, and those that are result from the decoding process. This document is primarily concerned with the latter. These issues are resolved by the following: — The handling of composition time stamps for audio composition units is specified. Special care is taken in the case of compressed data, like HE-AAC coded audio, that can be decoded in a backward compatible fashion as well as in an enhanced fashion. — Examples are given that show how a finite length signals can be encoded to an MPEG-4 file and decoded again to obtain the identical signal, excepting codec distortions. Most importantly, the decoded signal has nothing “extra” at the beginning or “missing” at the end.

This document specifies a syntactic description language for describing the structure of binary data. It covers the representation of an SDL specification in plain text, the syntax of the SDL and the semantic rules of the SDL. In scenarios where the usage or interpretation of the SDL are ambiguous or undefined, this document attempts to specify whether such a scenario is considered an invalid SDL specification or will result in undefined behaviour. NOTE While the SDL borrows from and contains some aspects of a general-purpose programming language, it is not intended, nor is it suitable, to be used for such a purpose. This is reflected in the fact that many concepts related to general-purpose programming languages are not addressed in this document. Examples of concepts considered irrelevant to the SDL and therefore not addressed in this document include storage of an SDL specification in a file, compilation, execution, input/output, execution environment and machine architecture.
