Abstract
To provide a control program downloading method that is used by a digital broadcast receiving apparatus equipped with a storing device which stores an update program and a non-update program that compose a control program. Under control of the update program, a new update program is received and written over data stored in a part of an area in the storing device where the non-update program has been stored. At the same time, a part of a new non-update program is received and written over data stored in another part of the area in the storing device where the non-update program has been stored. Once the new update program has been completely written into the storing device, under control of the new update program, the reception and writing of the part of the new non-update program is continued.
