The present invention is directed to a system and method for enabling a radio auditor or a television viewer (100) to access complementary information (101) related to a broadcast program (102) received in real-time. The preferred embodiment of the invention relates to a system and method for enabling a person (100) receiving a broadcast program (102), to select a plurality of topics drawing his or her attention (101) (103) and for immediately, or at a later time, accessing additional information related to these topics from the Word Wide Web. The system is based on a synchronization of the local times of receivers and transmitters according to a same universal-time (201) (202), so that the flow of information transmitted and received is always synchronized, independently of the relative positions of receivers and transmitters. The synchronization is done referring to an universal time such as the Global Positioning System Time (GPS-time), the Global Orbiting Navigational Satellite System (GLONASS) time or another suitable universal time based on a satellite system. The GPS or GLONASS receivers are connected or integrated to the broadcasting stations. At the receiver side, GPS or GLONASS receivers may be integrated or connected to devices (e.g., Personal Computers, wearable computers, Personal Digital Assistants (PDAs), smart phones or onboard mobile computers) that may be independent or separate from the radio or television receivers. The system is also based on a plurality of hyperlinks defined for given universal-time intervals of retransmission. The hyperlinks are associated with the transmitted information. The hyperlinks can be retrieved, selected and activated by radio auditors or television viewers during the time intervals for which they have been defined. |
