  • a first playback module which plays back the first stream;

    a second playback module which plays back the second stream;

    an output module which outputs played-back information played-back by the first or second playback module;

    a network connection module which is connected to a network; and

    a control module which controls each of said first and second playback modules, said output module and said network connection module, wherein;

    in a case where the first stream is played back by said first playback module, said control module sends identification information of the recording medium to a server via said network connection module and the network, and said control module obtains, from the server via the network and said network connection module, the second stream and control information relating to an output position and an output timing of played-back information at a time of playing back the second stream which is selected and transmitted from the server in accordance with a number of times of playback of the first stream performed by said playback apparatus stored in the server based on the identification information of the recording medium transmitted to the server, andsaid control module controls said first and second playback modules so as to superimpose one of the played-back information of the first stream and the second stream on another of the played-back information of the first stream and the second stream based on the control information and output the played-back information of the first and second streams thus superimposed from said output module.
