  • Advertisement playing and monitoring system
    Publication number: 20080120181
    Abstract: An advertisement playing and monitoring system uses a remote control system to transmit an advertisement file to an advertisement processing machine. The advertisement processing machine stores the advertisement file in a storage unit and plays the advertisement file on a display unit by an image-processing unit. The advertisement processing machine utilizes the image-processing unit to store the images of the display unit in the storage unit for being viewed by a remote monitoring system. Alternatively, the remote control system plays the advertisement file on the display unit via the advertisement processing machine. The remote monitoring system receives the images of the display unit via the advertisement processing machine.
