Incapable capabilities - less is more: improving user experiences and interoperability for streaming media services

Abstract

This document reviews existing functionalities for media capability mechanisms in the streaming media space. It shows the multitude of existing functionalities and provides an overview on what is used in practice. We provide recommendations to implementers and industry fora on how we can improve media capability signalling including focussing (extensible, yet compact) model for signalling relevant capabilities, provide a simple mapping to device APIs and support the correct implementation of capabilities on devices.
