Abstract
A storage device and method stores tuning-frequency data, and extracts a tuning frequency from a received signal. Based on the stored tuning-frequency data, the tuning frequency extracted by the first extracting unit is adjusted. The storage device is accessed by an information processing apparatus, and data from the storage device are processed by an information processing method.
