Claim Text:
1. A broadcast receiving apparatus comprising: a tuner unit which performs channel scanning; a tuner parameter generation unit which generates tuner parameter information which comprises channel information of channels scanned by the tuner unit and a channel setting value to tune to a channel corresponding to the channel information; a storage unit which stores the tuner parameter information; an input unit which receives input of a channel change request; a control unit which, if the channel change request is input, controls the tuner unit to tune to a requested channel using the tuner parameter information stored in the storage unit; an information processing unit which obtains program specific information (PSI) from signals received through the channels scanned by the tuner unit and stores the PSI in the storage unit; and an electronic program guide (EPG) storage unit which stores EPG information on the scanned channels, wherein, if the tuner unit is in an idle state, the information processing unit determines whether the audio/video PID information is changed or not by referring to the EPG information stored in the EPG storage unit, and updates the audio/video PID information included in the PSI.
