A user logs in(S601). If a multimedia function is selected, a controller senses that the multimedia function is selected(S602). The controller confirms whether a data download function is selected by using a PC or a base station(S603). If so, the controller decides whether to output downloaded data(S604). If so, an MPEG processor decodes the data(S605), and outputs the decoded data(S606). The controller decides whether to store the decoded data(S610). If so, the controller confirms whether to insert a watermark(S611). If so, the controller selects a kind of watermark according to size of multimedia data to be applied with a watermarking function(S612). The controller replaces an ESN of a terminal with a watermark character table, and generates a watermark for tracking an illegal user of the multimedia data(S613). The watermark is inserted through an encoder of the MPEG processor(S614). File information is stored by recording a file name and information showing whether the watermark is inserted(S615).
