PROBLEM TO BE SOLVED: To provide a display content monitor system, method, and program of an image receiver that monitors whether the display contents of ODDS are correctly displayed on an image receiver in an installed place or at a point in time that display is required.SOLUTION: When update of ODDS information is notified from a totalizator host 23, a video transmitter 18 of video transmission equipment 17 creates video for the ODDS information, identification information about the video, and a secondary code for the identification information. The video transmitter 18 transmits the identification information to an image receiver monitor device 21, and transmits a video for the ODDS information with the secondary code added thereto, to image receivers 28-i(i=1, 2, n) in a facility. A secondary code reader 33-i dedicated for each image receiver 28 reads the secondary code display position of the image receiver 28 and transmits the read data to the image receiver monitor device 21. If there is a difference between the identification information indicated by the secondary code and the identification information during display regardless of whether the secondary code is present or not in the read data, the image receiver monitor device 21 determines that the image receiver has a problem and provides warning. |
