Foreword
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

4.1 General
4.2Subclause provides the overall architecture for the storage of MIHS streams in ISOBMFF.
4.3Subclause provides information for synchronizing MIHS streams with other media.
4.4Subclause provides a summary of the referenceable code points, in tabular format.
5Clause 5 specifies extensions to the ISOBMFF for the storage of MIHS streams.
6Clause 6 specifies encapsulation and signalling for the delivery of MIHS streams over MPEG-DASH.
4.2 Haptic media
4.2.1 Structure of haptic media
ISO/IEC 23090-31 describes haptic experiences composed of perceptions containing channels, which in turn
containcontafin bands, as shown in Figure 1.

Figure – 1 — Structure of haptic media.
Experiences, perceptions, channels, and bands also contain metadata, which does not depend on time.
A perception may additionally contain an effect library comprising haptic effect definitions. Bands may
reference haptic effects in their containing perception’s effect library.
Bands additionally contain haptic effect definitions or references to effects in the containing perception’s effect
library to be presented at specific times, possibly following external events.
4.2.2 MIHS streams
ISO/IEC 23090-31 describes an MIHS format for streaming haptic media. An MIHS stream is composed of
MIHS units. Each MIHS unit is composed of MIHS packets.
