<p>A DVD audio signal reproducer(132_2) reproduces a DVD to generate a DVD reproduced audio signal (S5.1c, S2c). A reproduced signal determiner (134) determines whether the DVD reproduced audio signal is a 5.1-channel digital surround audio signal or a 2-channel digital audio signal, thereby generating a determination signal (SW). If the determination signal (SW) indicates that the DVD reproduced audio signal (S5.1c, S2c) is a 5.1-channel digital surround audio signal (S5.1c), a digital surround effector (160) converts the DVD reproduced audio signal (S5.1c) to a 2-channel digital surround audio signal (S2cd). <IMAGE></p> |
