An editing apparatus captures material data of audio and/or image data, edits the material data and generates main data. When an instruction to limit reproduction operation of the main data is made, the associated information including limitation information for limiting the reproduction operation of the main data so as to get a desired quality of content-representation is generated. The associated information is combined with the edited main data so that they are transmitted as the content data. Content-sending apparatus generates sending-data based on the data to transmit it. When the associated information including limitation information for limiting the reproduction operation of the main data is combined with the main data, content-reproducing apparatus performs reproduction operation based on the limitation information and controls reproduction speed, display size and the like. Content-representation apparatus represents audio and image at desired quality.
