The Radio Mosaic is a simple MHP application, therefore it doesn't need a mosaic generator.

The inputs are conveyed to a single screen on a dedicated TV channel, from which the user will be able to select the desired radio service and listen to its audio.

In addition to the channel logo, extra info about the program currently broadcasted can be displayed. The user can navigate among the mosaic components and switch from an audio stream to another while displaying the application.

Also, it is possible to perform a proper tuning to the selected channel or, otherwise, listen to the selected radio channel's audio while displaying a full screen customised background but still being tuned on the Radio Mosaic channel. 
Lookup.tv can provide both solutions in order to meet the customer needs, especially in terms of bandwidth saving.
