MPEG-UD Standard Enabling Responsive Remote User Interface

Various personalized recommendation services are provided through internet for users with different screen sizes and various sensors. It is also expected to be many competing service providers for similar recommendation service, and the users are expected to have the chances to select one of these services. However, the user related information as well as the environmental information around the user are not well reflected in the recommendation services, as the information types that the users may vary from user to user. If the user information and the environmental information are clearly defined and classified, the recommendation services may be able to provider broader services to the customers. Further, if the interfaces of the recommendation services are standardized, the users may have more choices as multiple recommendation services are using the same interfaces. This paper briefly reviewed the MPEG-UD standard, which is a standard for interfaces for recommendation services, using user and context information, and presented the concept of the Responsive Remote User Interface using MPEG-UD.
