<p>The present invention relates to methods and apparatuses for transmitting and receiving multimedia contents comprising at least two components (C1, C2); the reception method entails the reception of a first component (C1) from a first transmission medium (DVB) and the reception of a second component (C2) from a second transmission medium (IP), as well as the steps of: detecting (A4) a first "watermark" sequence from said first component (C1), detecting (A4) a second "watermark" sequence from said second component (C2), synchronizing (A5) said first and second components (C1, C2) on the basis of said first and second "watermark" sequences, and combining (A6) said synchronized first and second components (C1, C2) to form said multimedia content (MM); of course, said reception method provides the desired results if both components have been suitably and repeatedly marked prior to transmission.</p> |
