A remote gaming system for use with a wagering or gambling establishment such as a casino to enable a player's participation in a selected one of a plurality of wagering games from a remote location. The system includes a croupier station, a credit station and a player station remotely located from the croupier station and the credit station. The player station includes a live game display for displaying a selected one of a plurality of games being played at the croupier station, such as craps, roulette or keno. The player station includes a changeable playboard for displaying a selected one of a plurality of wagering possibilities corresponding to a selected one of the plurality of games being played and for displaying the results of the game played at the croupier station. The player station also includes a microprocessor for controlling the operation of the live game display and the changeable playboard.

Remote gaming system

A digital video compression and expansion system and its methods for compressing and expanding digitalized video signals in real time at rates up to NTSC color broadcast rates are disclosed. The system compressor receives digitalized video frames divided into subframes, performs in a single pass a spatial domain to transform domain transformation in two dimensions of the picture elements of each subframe, normalizes the resultant coefficients by a normalization factor having a predetermined compression ratio component and an adaptive rate buffer capacity control feedback component, to provide compression, encodes the coefficients with a minimum redundancy coding scheme and stores them in a first rate buffer memory asynchronously at a high data transfer rate from which they are put out at a slower, synchronous rate. The compressor adaptively determines the rate buffer capacity control feedback component in relation to instantaneous data content of the rate buffer memory in relation to its capacity, and it controls the absolute quantity of data resulting from the normalization step so that the buffer memory is never completely emptied and never completely filled. In expansion, the system essentially mirrors in reverse the steps performed during compression. An efficient, high speed decoder forms an important aspect of the present invention. The compression system forms an important element of a disclosed color broadcast compression system.

Digital video compression system and methods utilizing scene adaptive

An improved method and apparatus for calculating discrete cosine transform coefficients from a plurality of digitalized data is disclosed. The pipelined processor utilizes two basic types of circuits arranged in five computational stages. Shuffle and add circuits operate upon prearranged data components at the first, second and fourth stages, while shuffle, add and multiply circuits are used at the third and fifth stages.
