  • Patent number: 7811173
    Abstract: An apparatus and methods to provide a game system utilizing a normal household DVD player. The apparatus typically uses multiple remote controls and a game disc to provide an interactive game such as a quiz game. The game disc manipulates the address locations within the DVD to provide movement throughout the disc and the remote controls similarly at an offset to the address locations to source particular media files on the disc to be displayed on an associated television or similar device. The remote controls are also provided with a mechanism to avoid conflict between near simultaneous signals that include receivers within the remote controls to receive the signals, resolve the first remote control operated and only allow an operational code from that remote control to be received by the DVD player.
