Each piece of moving picture data, audio data, sub-picture data, and control information in the same block has the same reproduction time limit. Each piece of control information includes a mask flag indicating whether to mask a key interrupt requesting a special reproduction such as fast forward, the key interrupt being generated by the user by pressing a key on a remote controller and the like. The mask flag is effective for the key interrupt generated during the reproduction time limit stored in the control information.
