PROBLEM TO BE SOLVED: To provide a digital broadcasting receiver which is able to shorten whole search time. SOLUTION: A frequency is calculated with the start of searching (S31). When the frequency is RF-set (S33), the presence or absence of a broadcasting wave is recognized (S34). When it exists, the frequency is recorded (S35). When the recognition of the broadcasting wave on whole frequencies terminates, the recorded frequency is read (S41), and the frequency which is read is RF-set (S43) and is synchronization-set (S44). Information is acquired and is recorded (S45). When the acquirement of information on the whole recorded frequencies terminates (S42), acquired information is displayed on a display part (S51). Synchronization which takes time and information acquirement are executed only on the frequency where the existence of the broadcasting wave is recognized. Thus, the time required for searching can be shortened.
