Information technology — Multimedia application format (MPEG-A) — Part 22: Multi-image application format (MIAF)
This document specifies the Multi-Image Application Format (MIAF), which contains coded images, groups and sequences of images along with their metadata and the information about their relations to each other, all embedded in the High Efficiency Image File (HEIF) format. This document builds on the HEIF specification and defines the following: — a set of additional constraints on ISO/IEC 23008-12 (HEIF) specification, to simplify its file format options; — specific alpha plane formats; — a set of specific profiles and levels for the supported coding formats; — a set of specific metadata formats; — a set of brands, including application brands indicating conformance with specific profiles; — a set of rules for extending MIAF format to support additional coding formats, profiles, levels and metadata. This document also defines the normative behaviour for a MIAF reader and MIAF renderer. The MIAF specification is intentionally written to be extensible, and to allow for forward compatibility. The format is also permissive of the presence of other data, such as coding formats, metadata, and derived images.

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that
are members of ISO or IEC participate in the development of International Standards through
technical committees established by the respective organization to deal with particular fields of
technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with ISO and IEC, also
take part in the work.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
