The scope of Common Media Application Format (CMAF) is the encoding and packaging of segmented media objects for delivery and decoding on end user devices in adaptive multimedia presentations. Segmented Media Objects are derived from encoded tracks for storage, identification, and delivery. Delivery and presentation are abstracted by a hypothetical application model for segmented Media Objects described by a manifest that allows a wide range of implementations without specifying any. CMAF constrains media encoding and packaging to allow interoperable adaptive delivery of alternative tracks of segmented media to different devices, over different networks. ISO Base Media File format file constraints and brand, CMAF defines CMAF Presentation Profiles, CMAF Media Profiles and brands that specify track formats, media encoding constraints, and constraints on sets of CMAF Tracks that can be adaptively selected or switched during playback. This enables most Internet devices to play a CMAF Presentation conforming to a specified CMAF Presentation Profile. A manifest and player are assumed in the hypothetical application model. The manifest describes a CMAF presentation and its media Resources, which reference addressable CMAF Media Objects. A player can interpret a manifest, select, decode, synchronize, and present the Resources in a continuous multimedia presentation consistent with the encoded CMAF Presentation. CMAF does not specify a manifest, player, or delivery protocol, with the intent that any that meet the functional requirements can be used. See Section 6 for details of the CMAF Hypothetical Application Model, Media Object Model, Specified Objects, and Profiles.
