摘要
In order to realize real-time monitoring of video data, a video display device in a conventional video monitoring system is required in advance to have capacity for decoding encoded video data equivalent to that in all of the imaging devices connected to the video display device, preferably to that in the maximum number of connectable imaging devices or to the maximum volume of data which is displayable. According to the present invention, when encoded video data recorded on a video recording device is read out and is displayed on a video display device, the video display device receives video data acquired by decoding, with an imaging device, the encoded video data read out from the video recording device. Therefore, since the video display device is not required to have capacity for decoding, the configuration thereof can be simplified independent of the number of connected imaging devices, and cost reduction thereof can be achieved.
