The present invention is directed to a
system, method or
computer program, 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 (or to a recorded program previously broadcast and played back on an audio or
video player / recorder). The preferred embodiment of the invention relates to a
system and method for enabling a person (100) receiving a broadcast program (102), (or listening or watching a recorded program), to select a plurality of topics or sequences drawing his or her attention (101, 103) and for immediately, or later on, accessing additional information related to these topics or sequences from the Word Wide Web. The
system is based on a synchronization of the local times of receivers (or recorders) and transmitters according to a same universal-time (201, 202), so that the flow of information transmitted and received (or recorded) is always synchronized, independently of the relative positions of receivers (or recorders) 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 user devices e.g., Personal Computers, wearable computers, Personal Digital Assistants (PDAs), smart phones or onboard mobile computers (or to the audio or video recorders) 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 time intervals during the production of the broadcast program. These time intervals are synchronized with the
universal Time. The hyperlinks are associated with the transmitted (and recorded) 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, during the broadcast of the program (or during its playback).
