  • Publication number: 20150128167
    Abstract: A method to enhance broadcast content of an event received by a television set by supplying additional information related to the event. A user builds a request message for getting more information through a displayed menu where some items are extracted from metadata broadcast with the content. The request message, completed with user preference and identification data, is sent to a management center. The latter performs a search in local databases or in remote databases of providers distributed in a cloud comprising a plurality of internet services and resources. The search results are filtered before sending to the television set in the form of enhanced data comprising abstracts including at least text, or any combination of text with graphics or pictures.
