摘要： The present invention provides a digital broadcast receiver which reduces the time needed for channel scans by performing efficient channel scanning when broadcasts in a plurality of broadcast protocols are received. As a first phase channel scan, a first controller and a second controller divide a plurality of channels included in an overlapping frequency band of a first broadcast protocol and a second broadcast protocol, and execute parallel channel scans. After the first phase channel scan, the first controller scans channels in which electrical signals generated from electromagnetic waves received by a second tuner in the first phase channel scan could not be demodulated by a second demodulator, and the second controller scans channels in which electrical signals generated from electromagnetic waves received by a first tuner could not be demodulated by a first demodulator.

摘要： A digital broadcast receiving apparatus with enhanced tuning speed is provided. The digital broadcast receiving apparatus includes a data separating unit that separates the encoded stream of a tuned broadcast program and a plurality of latest tuning information from a digital broadcast stream, on the basis of stored tuning information recorded in a tuning information table, a decoding unit that performs a decoding process on the separated encoded stream, and a tuning control unit. The tuning control unit concurrently executes a first reception confirmation process to decide whether first tuning information included in the latest tuning information is consistent with the stored tuning information and a second reception confirmation process to decide whether second tuning information in the latest tuning information is consistent with the stored tuning information. The tuning control unit executes the first and second reception confirmation processes concurrently with the decoding process.
