Abstract
Abstract A video graphics generator 30 is provided for a video system such as an amusement machine which includes a video display device 18, user operable input devices 14, 16, 17 and a system controller 20 which is responsive to the user input devices and outputs video signals for driving the display device. The video graphics generator comprises a control unit responsive to an absence of operation of the user input means for a predetermined length of time to interrupt the video signals output by the system controller for at least a predetermined interval and to substitute alternative video signals for display on the video display device. An intermediate connector 27 for a standard interface between the system controller other elements of the video system can be used to sense signals for determining when to interrupt the normal video signals from the system controller.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
254 words
Video graphics apparatus for attachment to or incorporation in a video system which includes a video display device, user operable input devices and a system controller which is responsive to said user operable input devices and outputs video image signals for driving said display device, said apparatus comprising: a memory for the storage of alternative image signals for display on said video display device; a sensing arrangement connectable to said video system for detecting whether said user operable input devices are being operated; an interruption controller connected to said sensing arrangement; a video switch having a first video input connected, in use, to receive said video signals output by said system controller, a second video input connected, in use, to said alternative image signals from said memory, a video output connected, in use, to said video display device; and a control input connected, in use, to receive control signals generated by said interruption controller for selecting a connection of said first, or said second video input to said video output; wherein said interruption controller on the detecting an absence of operation of said operable input devices for a time period as determined by a timer, outputs a control signal to said video switch to select said connection of said second video input to said video output for a predetermined interval in order to interrupt said video image signals output by said system controller for said predetermined interval and to substitute the alternative image signals from said memory for display on said video display device.
Claim 2
Dependent Claim
254 words
Video graphics apparatus for attachment to or incorporation in a video system which includes a video display device, user operable input devices and a system controller which is responsive to said user operable input devices and outputs video image signals for driving said display device, said apparatus comprising: a memory for the storage of alternative image signals for display on said video display device; a sensing arrangement connectable to said video system for detecting whether said user operable input devices are being operated; an interruption controller connected to said sensing arrangement; a video switch having a first video input connected, in use, to receive said video signals output by said system controller, a second video input connected, in use, to said alternative image signals from said memory, a video output connected, in use, to said video display device; and a control input connected, in use, to receive control signals generated by said interruption controller for selecting a connection of said first, or said second video input to said video output; wherein said interruption controller on the detecting an absence of operation of said operable input devices for a time period as determined by a timer, outputs a control signal to said video switch to select said connection of said second video input to said video output for a predetermined interval in order to interrupt said video image signals output by said system controller for said predetermined interval and to substitute the alternative image signals from said memory for display on said video display device.
Claim 3
Dependent Claim
45 words
Apparatus as claimed in claim 1 wherein said interruption controller is responsive to operation of said user operable input devices during said predetermined interval to terminate said display of said alternative signals for resuming said display of said video image signals from said system controller.
Claim 4
Dependent Claim
74 words
Apparatus as claimed in claim 1 wherein said video system is an amusement machine having a first, attract mode and a second, play mode, and wherein said interruption controller is responsive to at least one signal representative of said amusement machine being in said attract mode, whereby interruption of said video image signals of said system controller by said alternative image signals is restricted to said attract mode of operation of said amusement machine.
Claim 5
Dependent Claim
128 words
Apparatus as claimed in claim 1 for a video system which includes a first multiple signal path connector connected to said system controller and a second multiple signal path connector connected to said video display device and to said user operable input devices, said first multiple signal path connector and said second multiple signal path connector being releasable connectable to one another, wherein: said apparatus comprises a multiple signal path intermediate connector arranged to be connected to each of said first and second multiple signal path connectors between said first and second multiple signal path connectors for interconnecting respective paths of said first and second connectors; and said sensing arrangement includes at least one signal line for sensing a signal on a signal path of said intermediate connector.
Claim 6
Dependent Claim
51 words
Apparatus as claimed in claim 4 wherein said signals on a signal path are representative of an operational state of a payment mechanism and/or of user operable devices and/or of indicator lights and/or of an audio output as an indication of a change of mode of operation of said video system.
Claim 7
Dependent Claim
50 words
Apparatus as claimed in claim 1, wherein said memory comprises re-writable solid state memory for storage of a plurality of screens of video graphics data, and said interruption controller including means for selecting a screen of video graphics data from said memory for generating said alternative video signals for display.
