Abstract
A receiver, such as that used in broadcasting, is provided with a simplified structure for storing and updating the receiver's control program and for preventing a loss of the control program because of a power outage during such updating. The structure includes a first storage means comprising an erasable, non-volatile memory and a second storage means comprising a volatile memory. The control program is stored in the first storage means and is executed to download and store a second program in the second storage means. The second program then is executed to download and store an updated version of the control program in the first storage means.
