A to multi-point session is not corrected are mistakes via welding reproductions; and transmitter (10) can also scheduling and a receiver point to point data repairing session. A transmitter (10) and is configured with by as of the receiver of for multi-point session retards the point to point repairing conversation and base randomization mechanism.
