    • An in-vehicle device (10) includes a first tuner (110A), a second tuner (110B), a signal processing unit (120), and a control unit (180) to control each unit. When switching from a currently received program to the same program broadcast by other broadcast station is switched, the control unit (180) determines whether the program of other broadcast station is delayed for the currently received program. When it is determined that the program of other broadcast station is delayed for the currently received program, the control unit sets a reproduction speed of the currently received program, according to content of the program, such that the currently received program is synchronized with the program of other broadcast station. The signal processing unit (120) outputs an audio signal at the set reproduction speed and the currently received program is switched to the program of other broadcast station after the programs are synchronized.
    • 车载设备(10)包括第一调谐器(110A),第二调谐器(110B),信号处理单元(120)和控制单元(180)。 当从当前接收的节目切换到由其他广播台广播的相同节目时,控制单元(180)确定是否延迟了当前接收的节目的其他广播台的节目。 当确定其他广播站的节目延迟当前接收的节目时,控制单元根据节目的内容设置当前接收的节目的再现速度,使得当前接收的节目与节目同步 的其他广播电台。 信号处理单元(120)以设定的再现速度输出音频信号,并且在程序同步之后将当前接收的节目切换到其他广播电台的节目。
