This invention relates to the subject matter disclosed in application Ser. No. 126,966 filed Mar. 22, 1971, a continuation of application Ser. No. 697,798 tiled Jan. 15, 1968, now abandoned; and application Ser. No. 713,862, filed Mar. 18, 1968, now U.S. Pat. No. 3,497,829.

BACKGROUND OF THE INVENTION This invention relates to an apparatus and method by means of which standard television receivers can be utilized as active rather than passive instruments. This is accomplished in certain embodiments by having participants manipulate controls of a control unit connected to the television receiver to cause a symbol, such as a rectangle, circle, ring, star, cross, spot or a plurality of spots, to be displayed upon the television screen by means of which the participants can play a variety of games, participate in simulated training programs, as well as carry out other activities. By way of example, modified versions of the well-known game of ping-pong may be played by two participants by physically or electronically placing an appropriate mask rep resenting the net upon the screen of the television receiver. Three displayed spots represent two paddles and a ball wherein the ball is moved in a particular di rection when hit by a paddle.

Heretofore, color and monochrome television receivers have been used generally by the home and other viewers as passive devices; i.e., the television receiver is used only as a display means for programming originating at a studio. The viewer is limited to selecting the presentations available for viewing and is not a partici pant to the extent that he can control or influence the nature of, or add to the presentation displayed on the receiver screen.

A standard receiver employed with auxiliary equipment to provide an active form of home entertainment is described in a patent application for Television Gaming and Training Apparatus," Ser. No. 126,966 filed Mar. 22, 1971 a continuation ofSer. No. 697,798, filed Jan. 15, 1968, and assigned to the assignee of this application. Since most homes are equipped with television receivers, the only cxpense required to provide added family enjoyment is the expense ofa control unit of one type or another.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide apparatus and methods for displaying video signals on the screen of a television receiver, where some or all of the video signals are both generated and controlled by apparatus external to the television receiver.

It is another object of the present inven .t i on to provide an apparatus and method wherein a standard color or monochrome television receiver is utilized as an active instrument for playing various types of games involving one or more participants.

It is a further object of the present invention to provide a device whereby an individual may pit his alertness, skill, manual dexterity and visual acuity against automatically controlled video displays.

It is yet a further object of the present invention to provide an apparatus which will generate spots such as squares, rectangles, circles, rings, stars, etc. which may be controlled by one or more participants for playing various types of games.

It is another object of the present invention to provide a cathode ray tube apparatus for displaying symbols to be manipulated by participants.

It is yet another object of the present invention to provide an apparatus which will allow one or more participants to actively use a standard television set while receiving background and other pertinent pictorial information from a cooperative commercial TV, closedcircuit TV, or CATV station, thus combining or alternating studio and home-generated information on the TV screen.

It is still another object of the present invention to allow the use of standard TV set for gaming or other activities without the need for any kind of internal electrical connection to the TV set for the introduction of video and/or chroma signals, connections being required to be made only to the externally-accessible antenna terminals.

In accordance with one embodiment of the present invention, a television gaming apparatus is provided for generating video signals in accordance with the standardized television format, which signals may be controlled by an individual operator by means of a joystick or other manually operative meansv The television gaming apparatus comprises control apparatus having included therein the necessary electronic circuits to produce video signals which are compatible with standard television receivers.

The control ipparatus has video signal control means mounted thereon for each access and connecting means are provided for coupling the video signals generated within the control box to the television receiver.

By way of illustration, the television gaming apparatus can be used for playing a game of ping-pong by providing on a TV screen two spots which represent paddles. Means are provided for enabling the players to control the vertical movement of the spots. Mears are also provided for generating on the screen of the elevision receiver a third spot which represents the ping pong ball, which spot automatically moves from an offscreen left position on an off-screen right position and vice versa unless hit by a paddle spot whereupon the ball spot will change direction. The players have further controls for changing the vertical position of the ball spot.

Suitable overlays or presentations from a cooperative TV station may be used in conjunction with said games to enhance the asthetic appeal thereof.

DESCRIPTION OF PREFERRED EMBODIMENTS The principal components of one embodiment of a television gaming system configured according to the invention are illustrated in FIG. I which is a pictorial view showing a television receiver 10 a control unit 14 and means I2 for connecting control unit 14 to receiver Ill. The television receiver I0 employed can be any of the standard commercially available models that are generally used for home entertainment. Either a monochrome or color television set may be used with the present invention since the basic principles of the invention apply to both types. The connection means 12 is in this embodiment a shielded cable, for example. shielded twin lead, and is attached to the antenna terminals of receiver 10 in conventional fashion.

Control unit 14 generates video signals shown as spots 20,. 20 and 21. The spots 20, and 20 are positioned on the receiver screen 18 by knobs 16,, I7 and 16 17 respectively. For clarity. the spot 21 is illustrated as a circle and the spots 20 are illustrated as diamonds. however, many shapes can be generated. In the devices to be described hereinafter, circles are generally employed.

Knob 16 controls the vertical position of spot 20 while knob 17 controls the horizontal position thereof. Thus, it can be seen that the spot 20, may be positioned at any point on the screen by the proper manipulation of knobs I6 and I7. Spot 20-; is positioned in like manner by knob 16 I7 In this embodiment spot 2] is automatically positioned on screen I8 without manual control. This will be described more fully hereinafter. A reset switch 26 is shown on the control unit 14 and is used to reset the picture on the television screen. For example, a game may be played in which one spot is to be positioned over the other and when this is accomplished one spot will disappear and the background will change color. When games of this nature are played, a reset means is required before play can be resumed. Reset switch 26 performs this function.

A knob I5 controls background color for color TV receiver applications wherein a chroma generator is employed in the manner set forth in said application Ser. No. b16966. Alternatively, control unit 14 maybe broken up into a master control unit containing the electronic circuits and individual control units containing control knobs 16,, 17 and 16 17 whereby each participant may operate from a position away from the other and so not to interfere with other players. This is illustrated in FIG. IA wherein control unit 14 is broken up into a master control unit 27 and individual control units 22 and 23. The master control unit 27 contains the electronic circuitry found in control unit I4 and controls 26 and IS. Knobs l6, l7 and 16,, I7 which position the spots 20 and 20 are situated on individual control units 22 and 23 respectively.

The knobs I6, 17 may be combined into a singlejoy stick permitting control of the horizontal and vertical spot positioning by a single control means.

Other spot position and control means (not shown) can be incorporated into the control unit(s) and these will be described hereinafter.

Rather than provide a separate control unit. the electronic circuitry of the control unit could be built into the television receiver as a constituent part thereof and the receiver sold as both an active and passive home cnterfainment system. Control units containing the actual manipulating controls can be provided as above,

A typical sequence of steps to play a game using the present invention would he as follows: 1. Attach connection means 12 to TV set ll) at the antenna terminals thereof. if not already attached; 2. turn the TV set on: 3. select the proper channel on the set for the control unit being used; 4. apply power to the control unit; 5. attach a mask on the face ofthe TV screen; if required for the game to be played; (1. begin the game.

Referring now to FIG. 2, a television screen 18 is itlustrated having three spots 24 24 and 25 displayed thereon. Spots 24 are "hitting" spots and spot 25 is a hit" spot. Spots 24, and 24 represent, for example. hockey players while spot 25 represents a hockey puck. An overlay mask 3!) of some type of transparent matcrial such as plastic or the like. hmg some type of pattern. picture or other illustration pertaining to the particular game to he played is shown in a lifted position. Prior to engaging in a game, the overlay mask is temporarily attached to television screen 18 and in such close proximity to it as not to create any distortion when viewed with reference to spots 24 and 25. One type of overlay mask represents a hockey field to be used for playing a modified game of hockey. Still another pattern could represent a ping-pong table. baseball diamond, etc. These are but a few of the many type games that can be adapted for use with the present invcntion.

Alternatively. rather than employ overlay mask 30., the pattern to be provided could be displayed directly on the screen 18. The pattern could be broadcast by TV stations or alternatively could be sent to a non-used channel over closcdcircu t or CATV lines. It could also be generated electronically in the video control system.

The basic theory of TV gaming devices as described herein is now set forth.

Referring to FIG. 3, at time zero the TV electron beam is at the upper left of screen 18. It starts moving quickly to the right and slowly downwards. Sixty-three and one-half (63.5) microseconds later a 5 microsecond horizontal sync pulse is fed into the TV set, causing the beam to fly back rapidly to the left of the screen. The beam then moves to the right for 63.5 microseconds until the next horizontal sync pulse causes the next flyhack to the left. After about 250 such horizontal scans (lines) the beam has progressed to the bottom of the screen. A vertical sync pulse fed into the TV set causes rapid (l millisecond) vertical flyback to the top of the screen and another cycle begins.

Now. still referring to FIG. 3. assume that the major portion ofthe screen is dark (beam blanked) except for the areas shown as SPOT 1 and SPOT 2. The spots are made by passing a (positive) unblanking video signal to the TV set when, and only when, the beam" is passing over the areas of the spots. [Quotes are used around beam because although there is no real beam when blanking is in effect. the scanning signals OCCTST and can he thought of as still moving the non-existent beam in the scanning pattern).

The video (unhlankingl signals required for spot generation as described with the aid of FIG. 3. To derive SPOT 1. assume that a pluse ofwidlh W is generated Tm microseconds after the occurrence ofeach horizontal sync pulse. Define these new pulses as P hori zontal video pulse forSPOT l. lfthese P pulses were used as unblanking (video) in the TV set. the beam would brighten whenever it had moved a distance equivalent to T from the left side of the screen. If would stay bright for a length equivalent to W and then darken. This would happen all during the vertical scan and bright little line segments of width W would appear to the eye as a vertical column l shown shaded in FIG. 3).

Now. SPOT 1 vertical video pulses P are made to be of width W, and to occur T milliseconds after the start of the vertical sweep. W, is on the order ololi microseconds. permitting some l0 horizontal scans to take place with P is on. If P were used alone as the unhlanking (video) signal to the TV set. ten lines the width ofthe set would be brightened while P was on and a bright horizontal bar of width W (shown shaded in FEG. 3) would be viewed.

As the last step in spot generation, SPOT 1 horizontal video pulses W and vertical video pulses (P are passed through a coincidence gate. The gate has an output only when both P and P are on. The gate output becomes SPOT 1 video (unblank) signal. From FIG. 3 it is obvious that the beam is now unblanked only where the P vertical shaded column and the P horizontal shaded bar overlap-Thus. a bright spot SPOT 1. comprised of about l0 small line segments. each W wide. is developed. SPOT 2 is developed in the like manner.

FIGS. 4 and 5 are block diagrams illustrating the manner in which the signals discussed with respect to FIG. 3 are generated.

The timing for the television gaming system is establishcd by a horizontal sync/sawtooth generator 31 and a vertical sync/sawtooth generator 32. The horizontal sync/sawtooth generator 31 generates a series of negative l Jrizontal sync pulses 33 having a repetition rate equivalent to the standard horizontal scanning fre quency used in United States commercial television receivers and the vertical sync/sawtooth generator generates a series of negative vertical sync pulses 34.

The vertical snyc/sawtooth generator 31 also generates a 15.75 KHz sawtooth wave 35 (refer now to FIG. 5). Sawtooth wave 35 has end limits of +E and 0. It is directly coupled to a SPOT 1 horizontal slicer 36. A slicc of the sawtooth ramp of length W is passed through the slicer. By varying voltage e delay T can be varied for spot positioning from left to right of the TV screen.

A 60Hz sawtooth 37 is generated by vertical synclsawtooth generator 32 and is similarly sliced in a SPOT 1 vertical slicer 2). to give ramp width W, and voltage controlled delay T The two sliced waves are differentiated by capacitors 38 and 39 which connect to the low input impedance of a SPOT 1 coincidence gate 40. Since the current through a capacitor is C de/dt. current pulses appear only during the ramp portions of the sliced waveforms. Although the slope of the vertical ramp is only about one two hundred and sixtieth times that of the horizontal ramp (60 Hz/l5,750 HZ), by making capacitor 39 approximately 260 times the value of capacitor 38. current plllsCS lll and i,, are made equal in magnitude. Both in, and i must be present to exceed in magnitude the (negative) thrcshold ofthe gate thus producing the SPOT] video signal.
