Abstract: An apparatus, method, and program for providing supplemental information related to video programs. Through a computer network interface, a user can request and receive specific supplemental audio/video information related to a video program. Alternatively, the supplemental audio/video information can be retrieved from a CD-ROM, or similar storage device. The video program can be, for example, a live broadcast television program or a time-shifted tape recording of a television program. The supplemental information is synchronized to the video program by using a time code which is integrated with the video program. This enables the supplemental information to be viewed and/or listened to in harmony with the events or action of the video program.

Abstract: A method and a system for a distributed electronic tournament system in which many remotely located players participate in a tournament through input/output devices connected to a central controller which manages the tournament. The method includes the steps of (a) uniquely identifying a player communicating with the central controller via an associated input/output device; (b) responding to payment of an entry fee by the player for allowing the player to participate in a tournament occurring within a fixed time window via an associated input/output device; (c) accessing a database to store in the database player information that is generated as the player participates in the tournament, such information being available for use in a subsequent tournament, which is administered by said controller and in which the player participates; and (d) awarding the player a prize for achieving a pre-established performance level in the tournament.

Abstract: A system is described for facilitating an Internet-based game of chance, particularly a computer-based version of a punchboard game having a grid with prizes associated with the various grid locations. The user can pay a central controller for each selection by providing a credit card number, or through other Internet transaction means. The central controller sends the user a fresh virtual punchboard (i.e. a game in which no selections have yet been made). The user selects a grid location, encrypts it, and then transmits it to the central controller. The central controller then generates prize values for the grid that it sent to the player. The user's computer stores the locations of each prize and determines whether the player's selection was a winner. If he has won, the player sends the decryption key to the central controller to decrypt his grid selection and authenticate his selection. The central controller then initiates a payment to the user.
