ABSTRACT:
A downloading apparatus and method for a digital broadcast receiver which updates a control program of an associated microcontroller with a control program received in a broadcast signal. The downloading apparatus examines the control program prior to initializing the microcontroller, and a new control program is downloaded if the examined control program is incomplete. The downloading apparatus also has a backup memory for abnormal events when downloading. A control program stored in the backup memory enables completion of the downloading.
