MEDIA CONTENT PROOF OF PLAY OVER OPTICAL MEDIUM

Abstract:

Content watermarks are generated for content that is to be rendered on a display of a display device. An image sensor is externally affixed to a corner of the display. When the content is rendered on the display, the image sensor captures the watermarks being played with the content from the area associated the corner where the image sensor is affixed. The image sensor captures the watermarks as images and streams the images back to the display device for storage. The stored watermarks are processed to verify that the corresponding content associated with the watermarks was played by the display device (visually rendered on the display of the display device).
