Distribution result verification method for information distribution system

摘要

A sender station sends a verification signal to itself after having sent data to be distributed. In the event that any one of receiver stations has failed to receive any one of data sets, the receiver station sends a predetermined jamming signal, to thereby hinder the sender station from receiving the verification signal transmitted to the sender station. When having failed to receive the verification signal, the sender station determines that any one of the receiver stations has failed to receive the data. In contrast, when having received the verification signal, the sender station determines that all the receiver stations have successfully received the data.
