PURPOSE: A method for determining a predetermined frequency associated with a transport stream in a digital broadcast receiver is provided to shorten the time to scan the frequency for each update. CONSTITUTION: A method for determining a predetermined frequency associated with a transport stream in a digital broadcast receiver, comprises the step of scanning(20) a frequency range, finding(22) a first frequency(FST) at which a first transport stream is received, reading(23) a first identifying data (ID) from the first transport stream, which allows to uniquely identify the first transport stream, extracting(24) a first predetermined frequency(F') associated with the first identifying data from a data base(25) by using the first identifying data, the database associating a predetermined frequency with predetermined identification data. The method is used in networks where the actual broadcasting frequency of the transport stream is different from the predetermined frequency of this transport stream, as contained in a network information table. |
