<p>The invention concerns the field of broadcasting, transmission and reception of audio-visual programmes containing interactive applications. Said applications need to be synchronised according to the audio-visual content of the event. The inventive method consists in generating a counter internal to the receiver and programme-specific. Said counter is timed by broadcast clock signals. Since said signals can be irregular, the counter is updated by specific descriptors when such irregularities occur. Thus, when displayed, the interactive event-related applications are properly synchronised.</p> |
