A home server having an integrated set-top function and a controlling method thereof are provided. The home server includes a processor unit, a tuner unit, an open cable broadcast receiving unit, and a set-top core unit. The processor unit receives an IPTV broadcast from an access network, includes control S/W for each broadcast type, receives a channel change request from a user, and stores and provides previously-watched channel information. The tuner unit includes a plurality of tuners and receives a MPEG2 TS according to the user's request. The open cable broadcast receiving unit releases a conditional access of the MPEG2 TS and encodes the received MPEG2 TS for copy protection. The set-top core unit receives the MPEG2 TS from the processor unit, the tuner unit and the open cable broadcast receiving unit, selects a channel in response to the control S/W, decodes the selected channel, and outputs video signal.
