摘要:
The electronic casino gaming system consists of several system components, including a microprocessor (12), a main memory unit (13) that is typically a random access memory, and a system boot ROM (14). Also included in the electronic casino gaming system are a non-volatile RAM (17), a mass storage unit (18), a disk subsystem (19), and a PCI bus (20). The disk subsystem (19) preferably supports SCSI-2 with options of fast and wide. A video subsystem (22) is also included in the electronic casino gaming system and is coupled to the PCI bus (20) to provide full color still images and MPEG movies.

A gaming machine is provided with a cabinet, at least one user-interface button, a value-receiving mechanism associated with the cabinet, a display unit associated with the cabinet, a processor disposed in the cabinet, system software representing a game that may be played by a player, encoded data generated from at least one message digest that was generated based on using an encoding function with the system software, loading software stored in memory that loads system software into random-access memory and verifies correctness and authenticity of the system software, and operating system (OS) software stored in memory that comprises an application programming interface including an application programming interface portion that provides a software interface to the display unit.

An electronic casino gaming system includes an unalterable ROM for storing a casino game authentication program, including a message digest algorithm program, a decryption program and a decryption key. A casino game data set containing casino game rules and image data is stored in a mass storage device, such as a local disk memory or a remote network file server, along with the signature of the casino game data set. The signature is an encrypted version of the message digest of the casino game data set, prepared using a hash function. Prior to permitting game play by a player, the casino game data set is transferred from the mass storage device to main memory and during this process the message digest is computed from the image data using a hash function stored in the ROM. The encrypted version of the message digest transferred from the mass storage device is decrypted using the decryption program and decryption key stored in the unalterable ROM. The two message digests are then compared for a match: if a match exists, game play is permitted; if a match does not exist, game play is prohibited. The authentication procedure is also used to check all casino game software, both programs and fixed data sets, stored in any memory devices distributed throughout the system, such as the system boot ROM, NVRAM and all sub-system memory devices. The authentication procedure is run whenever a particular program or fixed data set is scheduled for use by the system, and also at periodic intervals and on demand.

For controlling the direction and rate of movement of an image on a raster scan display, a first set of counters is arranged to generate digital pulses for use as horizontal and vertical sync pulses for use in conjunction with a video adder for controlling the image on the display. Means, such as a second set of counters, driven by another clock means, provides an output which is compared to that of the first named counters to provide information signals to the video adder for controlling the location and movements for the image being displayed.

User exposure to media items is detected and measured. A mobile client device carried by a user digitally samples the audio environment of the user on a regular basis. These samples are transformed into a stream of data signatures and compared with reference media items to detect user exposure to the reference items. Purchase behavior following exposure to selected media content items can be detected and tracked as well, so as to gauge effectiveness of media items such as advertisements.
摘要:
Improved electronic gaming apparatus, including a cabinet for housing video and sound generating electronics, coin-handling and pay-out mechanism and a video display screen. The display screen is substantially taller than it is wide and may have a touch screen associated therewith. Although the displayed video presentation may take any form, the display may include graphics replicating the standard play board at top, game board in middle, and principal user input interface below.
