Edition - 1: Multi-Image Application Format

Publication Year: 0
Status: released
Motivations: The HEIF (High Efficiency Image File) specification (ISO/IEC 23008-12) defines a file format for inclusion of an image or sequences of images with associated metadata and their relationship to each other. While the HEIF specification defines the file format and general codec requirements for the included codecs, it does not define specific interoperability points by which capturing devices, editing applications, storage systems, cloud and delivery networks, and playback devices and applications can interoperate with each other. For instance, a capturing device may use one of HEIF codecs with a specific HEVC profile and level in its created HEIF files, while a playback device is only capable of decoding the AVC bitstreams.
Objectives: A new multimedia application format, the Multi-Image Application Format (MIAF) will enable precise interoperability points for creation, reading, parsing and decoding of images embedded in HEIF. The MIAF specification will be compliant to HEIF format and only defines additional constraints to ensure higher interoperability.
