A technique is described for managing the local storage of digital assets, such as audio, (moving or still) pictures, text, executable code and combinations thereof, in the storage device of a user appliance, such as a personal video recorder, set top box, mobile phone or storage server. A digital asset is received that is intended for local storage in the storage device and that has been pushed down from a source. A rank order is assigned to each digital asset stored or to be stored in a storage device that has a finite capacity storage space for storing digital assets. The assigned rank orders of one or more of the digital assets are repeatedly examined and a digital asset having a rank order that is lowest among the examined rank orders may be deleted. Each rank order is assigned based on predefined default ranking rules and user instructions pertaining to one or more of the digital assets that are capable of causing a deviation from the default ranking rules, if any have been provided by the user. A signal may be provided containing executable instructions that can be executed at programmable electronic circuits for performing the above steps. Such a signal may be stored on a storage medium. A system for performing the above steps may include a receiver for receiving the digital assets and a processor for assigning ranking orders and for repeatedly examining the ranking orders and selectively deleting digital assets with low ranking orders.
