摘要： A digital broadcast receiving device includes a first processor for extracting added information, a storage device for storing the added information, and a second processor having a low power consumption mode and a normal power mode, for effecting the circuit control for the watching and listening operation according to a preset program and the added information. The first processor informs the second processor that the added information is extracted, the second processor changes the mode thereof to the normal power mode when it is informed from the first processor that the added information is extracted while it is set in the low power consumption mode in the standby state, writes the added information extracted by the first processor into the storage device, and changes the mode thereof into the low power consumption mode after completion of the write operation.
