A broadcasting receiving apparatus and a method thereof are provided to compensate time deviation between two broadcasting signals during conversion between a digital broadcasting receiving mode and an analog broadcasting receiving mode, thereby preventing a screen from passing or being overlapped and accordingly improving broadcasting receiving quality. A delayed-time measuring unit(120) compares an analog broadcasting signal with a digital broadcasting signal of the same channel to grasp a time deviation between the two signals, and measures delayed time of the digital broadcasting signal. A signal measuring unit(110) measures signal sensitivity or signal attenuation with respect to the digital broadcasting signal, and determines a signal to be displayed among the digital broadcasting signal and the analog broadcasting signal according to the measurement result. A time delay unit(130) delays output of the analog broadcasting signal as much as the delayed-time of the digital broadcasting signal measured by the delayed-time measuring unit, and synchronizes the digital broadcasting signal with the analog broadcasting signal.
