Abstract: A method, apparatus and computer program product describing groups of overlays, such as semantically correlated overlays, to background media content. In the context of a method, a group of overlays to background media content is defined by metadata (60). The overlays include semantically correlated overlays having alternative overlays representing content with different levels of detail or overlays providing different choices of content. The method also includes receiving client selection of a respective overlay from a group of overlays (62). In response to the client selection, the method causes the respective overlay to be provided. The respective overlay is received (64) for presentation concurrent with background media content (68).
