A method of realizing a personal video recorder (PVR) using a home network device is provided. A client receives contents and replays the contents in a home network. The client uploads first contents received from a real time broadcasting channel to the server from a time when an external time-shift input is received, terminates the uploading of the first contents if an external replay input is received during the uploading of the first contents, replays the first contents whose uploading is terminated from a portion requested by the external replay input, and simultaneously uploads second contents to the server, received from the real time broadcasting channel at a time when the uploading of the first contents is terminated. A user can watch a live broadcast using a time-shift function such as a PVR via a home network device without a separate PVR.
