This Web Application Video Ecosystem Content Specification (WAVE Content Spec) is derived from the ISO/IEC standard, “Common Media Application Format for Segmented Media” [CMAF]. The scope of the WAVE Content Spec is the encoding and packaging of segmented media for delivery and decoding on end user devices in adaptive multimedia presentations. The WAVE Content Spec extends [CMAF] by referencing additional Media Profile specifications. The WAVE Content Specification defines WAVE Programs that contain a sequence of one or more CMAF Presentations with encoding constraints to enable continuous rendering and user experience on targeted devices. The 2019 Edition additionally defined a Baseline Splice Constraint Profile targeting the majority of existing adaptive streaming devices. The purpose of the Content Specification is two-fold: firstly, to decouple the preparation of content from the devices which will eventually consume it, so it can be used with different protocols and platforms; and secondly, to assist content distributors in preparing content compatible with the digital media playback devices they wish to target. WAVE Media Profiles, Presentation Profiles and Splice Constraint Profiles define options allowed in content. Corresponding functionality is required in compatible Web applications and devices to request, decode, decrypt, and render the content as intended. The application, device, and test requirements needed for interoperability are specified in other WAVE specifications.
