Abstract
The invention relates to a communication system comprising a plurality of interactive terminals which communicate with a master station via a transmission medium. The invention is particularly applied to interactive satellite broadcast systems. The invention relates to a request mechanism permitting the interactive terminals to have reservations assigned to them on the transmission medium for transmitting information to the master station. When a terminal receives assignments that have not yet expired, it temporarily stores them in an assignment memory. The invention comprises taking the number of assignments contained in this memory into account when a new request is transmitted. It thus permits to avoid that requests for the assignments that have already been granted are formulated again.
