CIMM DEFINITION: Universally used button (typically RED) that is both on-screen and on the remote to signal that there is interactive (value added) content associated with the program. Does not have to be branded to a specific provider. ITV content is mandated to use it, mostly seen in Europe on the BSkyB Platform.
NOTE – See http://www.broadbandbananas.com/vvenhanced.html for examples of this kind of “universal” button usage.
