DIGITAL SET-TOP BOX HAVING DETACHABLE STORAGE ELEMENT, AND METHOD FOR STORING DIGITAL BROADCAST PROGRAM

摘要

PURPOSE: A digital set-top box having a detachable storage element, and a method for storing a digital broadcast program are provided to continuously store a program by simply exchanging storage elements all the time. CONSTITUTION: A control unit applies a storage element exchange signal to change storage elements(401). According to the exchange signal, the received data is continuously stored in a first storage element or is stored in the existing recording medium(402). It is judged whether a CD signal reporting insertion of a new storage element is detected(403). If so, power and a control signal are applied to the new storage element(404). Another control signal is applied to the second storage element after delaying operation for a predetermined time so that a user attaches and detaches the second storage element to and from a set-top box even in a state that power is applied to the second storage element(405,406). The operation and a function menu of the second storage element are activated and a file system is updated(407,408). The received and stored data in the first storage element are transferred to the second storage element(409). If the second storage element is not detected, a new storage element menu is disabled and the file system is unloaded(410,411).
