PROBLEM TO BE SOLVED: To reproduce a lecture reproduced in the past without affecting other participants of a lecture when giving the lecture over a network.;SOLUTION: A network lecture system 10 comprises a lecturer terminal 100 and a plurality of participant terminals 200. In the network lecture system 10, lecture data is approximately simultaneously transmitted to all the participant terminals 200 in real time. Each of the participant terminal 200 can reproduce a lecture, and can accept input of designation information, which in turn designates a certain recording term of the lecture, to transmit this information to the lecturer terminal 100. When the designation information is received, the lecturer terminal 100 identifies the participant terminal 200 that is a transmission source of the designation information, specifies the recording term designated by the designation information and transmits lecture data of the specified recording term, namely, lecture data reproduced to the participant terminal 200 of the transmission source.;COPYRIGHT: (C)2009,JPO&INPIT
