The adjustment of regional code information in which a first region code and a first nation code associated with the first region code are received from an optical disc. At least one of a broadcasting signal or an IP address are received at an electronic device, such as a DVD player. A second nation code is extracted from the broadcasting signal and/or the IP address, and a second region code associated with the second nation code is determined. The second region code is compared with the first region code, and the second region code and the second nation code are stored at the device if the first region code and the second region code do not match.
