Abstract

A receiving apparatus is provided with a buffer memory. The filling and emptying of this buffer memory is simulated (103, 104, 202, 203) at the transmission end, and the transmission speed of the useful data is decelerated (106), when the simulation indicates the occupancy by useful data of a determined fraction of the capacity of the buffer memory, to avoid overflow. The value of the capacity of the buffer memory, as well as that of its emptying speed, are acquired in the course of a protocol procedure which precedes the transmission of the useful data.
