VIDEO SIGNAL DISTRIBUTION SYSTEM, VIDEO CONTENT CREATION DEVICE, VIDEO MONITORING DEVICE, AND TRANSMISSION ABNORMALITY DETECTION METHOD OF VIDEO SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide a video signal distribution system which allows for transmission abnormality detection of various video signals, such as the abnormality of a content server, wrong operation, abnormality of the transmission path, and the like, without having to place the attendant for monitoring the screen of an in-field video display device.;SOLUTION: A video signal distribution system includes a video content creation device for creating a video content and outputting a video signal obtained by adding the detection information for detecting the transmission abnormality to the video content, and a video monitoring device for detecting the transmission abnormality of the video content by saving the video signals added with the detection information, as the screen information, at predetermined intervals and comparing them. Consequently, the transmission abnormality of various video contents can be detected, without having to place the attendant for monitoring the screen of an in-field video display device.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
