Requirements for the semantics of a Common User Profile used to personalize audiovisual media

This paper describes the requirements for the semantics of a Common User Profile (CUP) intended to express users’ needs when accessing audiovisual content. The CUP facilitates the storing, sharing and transfer of a users’ personalized accessibility preferences and user interface requirements across different devices, applications, and formats such as virtual worlds within allowable limits set by the content providers and/or their devices capability. The document does not define the profile itself but rather defines a set of parameters, and their semantics, needed to implement such a profile and how any optional applications can be included. The CUP is targeted at broadband, digital TV, computer and smart phone software and web-based audiovisual systems. It can also be applied to interactive, augmented and virtual reality applications.
