Abstract:
An abnormality detection device according to the present invention is a video transmission state abnormality detection device connected via a network to a plurality of video transmission devices, an IP packet transfer device on the transmission side, an IP packet transfer device on the reception side, and a plurality of video reception devices. The video transmission state abnormality detection device prepares a transmission/reception IP flow table by aggregating IP flow information for the devices, detects an abnormality in transmission on the basis of the transmission/reception IP flow table, and specifies the location of the abnormality. The abnormality detection device according to the present invention can automatically detect the amount of traffic and specify which part of a transmission path an abnormality is caused on, without the need for advance setting. Therefore, video or sound traffic can be monitored efficiently.
