ETSI TS 101 499 describes an application that provides a visual accompaniment to a radio service.

In respect to previous versions of the present document, hybrid radio provisions have been added to allow a seamless experience for users when consuming radio services delivered by digital radio broadcasting systems (DAB, DRM) or IP or a combination of both. The use of the present document allows content to be created once by the service provider for delivery by both mechanisms and allows manufacturers to implement devices with many common elements.

The application can be delivered using broadcast or IP, or a combination of the two.
