<p>Primary programs (P1, P2, ...) and commercials (= secondary programs C1, C2, ...) are transmitted alternately and, in the 'normal mode' of a display system according to the invention, they are applied directly to a display (3). Tertiary programs (C1*, C2*, ....) with commercials are transmitted in parallel and expanded in time, i.e. with a small-bandwidth, and are continuously stored in a memory (4). When the user presses 'pause' during the 'normal mode', the tertiary programs (commercials C1*, ...) that have been recorded until then will be shown, and the program (P3, ...) itself will be delayed, i.e. stored in a buffer (5). When the user resumes watching, he can start with the primary program (P3) where he left off and (some of the) the commercials (C3, C4, ...) broadcast at the end of the program will not be shown.</p> |
