Broadcast receiver, control method, and program



<P>PROBLEM TO BE SOLVED: To curtail the time required for switching to an alternative RDS broadcast concurrently serving a program identical to that of an RDS broadcast when the RDS broadcast quality is deteriorated in the RDS radio receiver 10. <P>SOLUTION: Search of the alternative station is started by controlling tuners in good and bad broadcast receiving conditions of a main tuner 12a and a sub-tuner 12b selecting the same RDS broadcast (a source station) during a diversity period before search of the alternative station to respectively select a source station and an AF station (alternative station) (S48 YES→S49). When the receiving quality of the source station and the AF station is respectively low and high (S51 YES→S52 YES), it is checked whether a signal is received or not from the AF station during the latest constant period in the past (S53). When the signal is received, it is determined whether the PI (program identifier) code of the AF station obtained by reception matches the present PI code of the source station (S54). When the determination result is YES, the tuner selecting the source station is changed to the AF station (S55) to return to the diversity process (S55→S46). <P>COPYRIGHT: (C)2010,JPO&INPIT
【課題】RDSラジオ10において、RDS放送の品質が低下した時に、該RDS放送の番組と共に同一番組を放送中の代替RDS放送へ切替える時間を短縮する。 【解決手段】代替局探索前のダイバーシティ期間に同一RDS放送(元局)を選局しているメインチューナ部12a及びサブチューナ部12bの内、放送の受信状態が良い方及び悪い方にそれぞれ元局及びAF局(代替局)を選局させて、代替局探索を開始する(S48正→S49)。元局及びAF局の受信品質がそれぞれ低及び高となっている場合(S51正→S52正)、直近の過去一定期間にAF局を受信しているかを調べ(S53)、受信している場合には、その時取得した該AF局のPI(番組識別子)コードが元局の現在のPIコードと一致するか否かを判定する(S54)。判定が正であれば、元局を選局しているチューナ部をAF局へ変更し(S55)、ダイバーシティ処理へ戻る(S55→S46)。 【選択図】図2
