Resumen:
Synchronizing TV contents with applications is a topic thathas gained much interest during the last years. Reaching the viewers throughvarious channels (TV, web, mobile devices, etc.) has shown to bea means for increasing the audience. Related to the above, the hybridTV standard HbbTV (Hybrid Broadcast Broadband TV) synchronizesthe broadcast of video and audio with applications that may be deliveredthrough either the broadcast channel or a broadband network. Thus,HbbTV applications may be developed to provide contextual informationfor emitted TV shows and advertisements. This paper reports onthe integration of the automatic generation of geographic focus of textcontent with interactive TV. In particular it describes a framework forthe incorporation of geographic context to TV shows and its visualizationthrough HbbTV. To achieve this, geographic named entities are rstextracted from the available subtitles and next the spatial extension ofthose entities is used for the production of context maps. An evaluationstrategy has been devised and used to test alternative prototype implementationsfor TV newscast in Spanish language. Finally, to go beyondthe initial solution proposed, some challenges for future research are alsodiscussed.
