摘要： A monitoring method for monitoring a video/audio signal transmitted from a transmission source to a transmission destination has a step of storing the video/audio signal transmitted from the transmission source to the transmission destination repeatedly for a predetermined time period, a step of comparing a first characteristic amount extracted from the video/audio signal before the transmission and a second characteristic amount extracted from the video/audio signal after the transmission in real time, a step of determining an error occurrence when there is a difference of a predetermined value or more between the first characteristic amount and the second characteristic amount, and a step of transmitting the stored video/audio signal to a predetermined destination when an error occurrence is determined.

摘要： 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.

摘要： A video/audio signal transmitted from a transmission source 10 to transmission destinations 20A and 20B is stored repeatedly for a predetermined time period. Thus, for example if the video/audio signal is overwritten at predetermined timing, it is sufficient to have a small storage capacity for the video/audio signal. Also, the video/audio signal on which an error has occurred remains without being overwritten at the time of determination that an error has occurred. Accordingly, by transmitting this signal to a predetermined destination, a detailed error analysis can be made promptly on the basis of the transmitted video/audio signal.
