Abstract

A gaming console is provided which produces audit mode displays via the machine controller instead of the display controller.

This arrangement allows a simple display controller to be used for the basically text based display information of audit mode while continuing to allow high quality graphics to be displayed via the separate display controller during a game playing mode.

A secure controller 11 runs a game program and generates a stream of display commands 19 to a display engine 18 which then generates the video representation of the game via video output signal 17 which is transmitted to a video multiplexer 14 within the secure controller 11. The multiplexer 14 selects between the game video output 17 and an audit mode video signal 26 under control of an output selection function 12 which is under the control of the secure controller. During audit mode the selection function 12 will cause the second input signal 26 to the multiplexer to be displayed, this second signal being generated by the lower performance display controller 13 contained within the secure controller 11.

Claims

1. A gaming machine comprising a secure game control means, game display engine means responsive to the secure control means to produce a game video output and display means responsive to the game display engine means to display a game image, the secure game control means further comprising second display control means and display signal processing means, the display signal processing means receiving the game video output and an output from the second display control means, and providing an output to the display means comprising the game video output when the machine is in a game playing mode and comprising the output from the second display control means when the machine is in a secure display mode.

2. The gaming machine of claim 1, wherein the signal processing means is a merging circuit which superimposes the output of the second display control means over the image output from the display engine means.

3. The gaming machine of claim 2, wherein an audit mode of the machine is provided which is a secure display mode, such that during the audit mode the output from the second display control means comprises audit data indicating status or setup data of the machine.

4. The gaming machine of claim 3, wherein the signal processing means presents secure audit data during audit mode, and secure game information during game playing mode.

5. The gaming machine of claim 4, wherein the secure game information is payout information and available credit information.

6. The gaming machine of claim 3, wherein the display engine is a high resolution video graphics controller capable of producing high quality animated ₃D graphics images.

7. The gaming machine of claim 6, wherein the second display control means is a lower performance display controller than is the game display engine means.

8. The gaming machine of claim 1, wherein the signal processing means is a switching means which switches between the display engine video output during game playing mode and the output of the second display control means during secure mode.

9. The gaming machine of claim 8, wherein an audit mode of the machine is provided which is a secure display mode, such that during the audit mode the output from the second display control means comprises audit data indicating status or setup data of the machine.

10. The gaming machine of claim 9, wherein the display engine is a high resolution video graphics controller capable of producing high quality animated ₃D graphics images.

11. The gaming machine of claim 10, wherein the second display control means is a lower performance engine display controller than is the game display means.
