A system and method for multi-destination delivery which ensure data delivery efficiency of a certain level. A talker delivers data to a plurality of listeners. The data retransmission request section of each listener analyzes the received data to detect erroneous data and missing data, and sends a data retransmission request to the data retransmission control section of the talker. The talker retransmits the data to the listener in response to the data retransmission request. The line monitoring section of the listener monitors line status, and provides the listener line status aggregating section of the talker with the result of the monitoring. Consequently, the talker is made aware of the line status of the listener in substantially real time. The data retransmission control section eliminates a "problematic listener" from the destinations to which data are to be delivered based on circumstances. Accordingly, it is possible to ensure the quality of data delivery.
