US Patent 7266341 Digital broadcast receiving device and digital broadcast receiving method

A tuner receives service information SI for each of a plurality of channels included in a digital broadcasting signal at one carrier frequency. A service information extraction unit extracts and stores the received service information preset into a memory. The operator selects the service information stored in the memory and acquires a program. The tuner may have a function of automatically scanning the carrier frequency all over the receivable frequency bands and store it. The temporary service information having irregular broadcast time is stored in the memory through an operation of an operation input unit. When the temporary service information is not broadcast, such temporary service information is deleted from the memory.
