<p>A monitoring system checks a transmission error of a video/audio signal transmitted from a source (10) to a destination (20A, 20B) by comparing in real time a first feature extracted from the pre-transmission video/audio signal and a second feature extracted from the post-transmission video/audio signal. The transmitted video/audio signal is repeatedly stored for a predetermined period of time. When the system judges that a transmission error has occurred, it transmits the stored video/audio signal to a predetermined address. Thus, the transmission error of the transmitted video/audio signal can be analyzed rapidly and in detail.</p>
