Abstract
In an interactive audio-video digital distribution system a pointer is transmitted at least once every T milliseconds to indicate the position of a time marker. An interruption (V) occurs every T milliseconds. A given number N of integer frames being transmitted in T milliseconds, there remains only space for transmitting a portion containing R symbols of the N+.sup.th frame before the next interruption. Following transmission of a signaling packet (x) with a pointer indicating a number (x) of symbol periods, during the next interruption N packets will have been completely transmitted since the last pointer, plus R symbols. The end of the transmission of this packet is waited for, that is, U.dbd.C-R symbol periods before a new signaling packet (x-U) is transmitted. The value of the pointer contained in this packet will thus have to take this offset into account as it is decremented by U symbols, that is, x-U, and so on.
