PROBLEM TO BE SOLVED: To continuously output a specified program even when a reception area is changed, without using an antenna apparatus for GPS or a GPS circuit. SOLUTION: A receiver 100 receives the physical channel signal of a designated digital broadcasting, decrypts an information source, and generates the reception condition of the digital broadcasting during reception. The receiver 100 receives the prescribed physical channel signal, decrypts the information source, and generates the reception condition of the physical channel signal during reception at present. The receiver 100 stores first arrangement information expressing channel arrangement for multiplexing on the received physical channel signal of the digital broadcasting, and previously stores second arrangement information expressing the channel arrangement of a whole country. The receiver 100 estimates a mobile direction with respect to a present service area, based on the two kinds of reception states and the first and second arrangement information, so as to determine the physical channel signal and logical channel signal of the subsequent digital broadcasting.
