Systems and methods are operable to control operation of a portable media device based on machine readable information of a graphical artifact shown on a display concurrently with presentation of a video portion of a media content event. A portable media device, using a portable media device provisioned with an image capture device, captures at least one image that includes the display that is presenting the graphical artifact and the video portion of the media content event, identifies the graphical artifact in the captured at least one image, determines the machine readable data based on the identified graphical artifact, and operates the portable media device to perform at least one operation based on the determined machine readable data.
