A display controller includes a digital processor adapted for data communication with a central computer, for controllably downloading alphanumeric data and one or both of image attribute data and complete or partial screen images to be displayed on unmodified standard commercial television receivers. Data memory and program memory are coupled to the digital processor, which stores image formatting data or complete images. Programmable logic circuits are coupled to the data output of the digital processor, and in conjunction with the digital processor convert the attributes presented on the data output of the digital processor into a pixel data field wherein each pixel is encoded to one of a number of available color combinations. A color palette converts the pixel field into RGB data. A video encoder takes the RGB data and modulates a subcarrier signal to provide a composite video output. The display controller is preferably part of a networked gaming system with a central computer system managing entry validation and/or selection or crediting of winning entries in a wagering game having numerous players. Distributed agent terminals in data communication with the central computer system manage input of player data and issue of player entries as point of sale terminals under supervisory control of the central computer. A plurality of standard commercial television receivers are coupled respectively to the video buffers, and simultaneously display the image in conjunction with the respective agent terminals, thereby displaying game data to numerous players at retail locations.
