Abstract:
1. A multimedia data recording and playing device comprising: a PVR (personal video recorder) processor for controlling to store received multimedia data in an activation mode where the received multimedia data is played and stored simultaneously; a storage for storing the received multimedia data under a control of the PVR processor; and a time shift function switcher for switching from the activation mode into a deactivation mode where the received multimedia data is played, but not stored in the storage simultaneously, when a request for a time shift function from a user is not detected within a time interval calculated by a user-time-usage-pattern algorithm analysis, wherein whether or not the time shift function is requested within the time interval is repeatedly determined while operating under the activation mode, and the time interval is a predetermined fixed time for a determination that the user seldom selects the time shift function in the future.
