Abstract
The present invention is directed to a system, method and computer program for enabling a user (an auditor or a viewer) to access complementary information related to one or a plurality of sequences or topics of interest in a recorded program previously broadcast on the radio or television and played back on a device, such as an audio or video tape or disk recorder/player. The preferred embodiment of the invention relates to a system and method for enabling a person listening to or watching a recorded program, to select one or a plurality of topics drawing his or her attention and for immediately receiving further information related to these topics from the World Wide Web. The system is based on the synchronization of local times of transmitters and recorders. The flow of information transmitted, received and recorded is always synchronized, independently of the relative positions of recorders and transmitters.
