A 60 Hz pulse train 37 is generated by vertical sync generator 32 and is similarly utilized to a DOT 1 vertical generator 29 to provide width WV and voltage managed delay TV1. E and O. It's instantly coupled to a DOT 1 horizontal generator 36. By varying voltage eH1, delay TH1 may be varied for spot positioning from left to right of the Television display. FIG. 3. To derive DOT 1, assume that a pulse of width WH is generated TH1 microseconds after the incidence of each horizontal sync pulse. Outline these new pulses as PH1 -- horizontal video pulse for DOT 1. If these PH1 pulses have been used as unblanking (video) within the Television set, the beam would brighten every time it had moved a distance equivalent to TH1 from the left aspect of the display screen. After about 250 such horizontal scans (strains) the beam has progressed to click the following page bottom of the display. If PV1 were used alone because the unblanking (video) sign to the Television set, ten traces the width of the set would be brightened while PV1 was on and a shiny horizontal bar of width WV (shown shaded in FIG. 3) would be seen. Alternatively, slightly than make use of overlay mask 30, the pattern to be supplied could be displayed immediately on the display screen 18. The sample will be broadcast by Television stations or alternatively may be sent to a non-used channel over closed-circuit or CATV traces.
Prior to engaging in a sport, the overlay mask 30 is briefly hooked up to television screen 18 and in such close proximity to it as to not create any distortion when viewed with reference to dots 24 and 25. One kind of overlay mask represents a ping-pong internet 19 for use for playing a modified sport of ping-pong. An overlay mask 30 of some sort of clear material similar to plastic or the like, having some type of sample, picture or other illustration pertaining to the actual recreation to be played is proven in a lifted place. Still another sample may signify a handball or volleyball court, and so on. These are however just a few of the numerous sort video games that may be tailored to be used with the present invention. A lesson from the previous is that Handball (solely) gamers might play an excellent recreation of Racquetball, but Racquetball (only) players couldn’t even start to play Handball.
This is due to its off yellow shade, its, nevertheless, appropriate for rookies and recreational gamers. Nevertheless, within the embodiment of FIG. 5, no coincidence gate is required. The gate has an output solely when each PH1 and PV1 are on. From FIG. 3 it's apparent that the beam is now unblanked solely where the PH1 vertical shaded column and the PV1 horizontal shaded bar overlap. Knob 161 controls the vertical position of dot 201, while knob 171 controls the horizontal position thereof. As the final step in dot generation, dot 1 horizontal video pulses (PH1) and vertical video pulses (Pv1) are handed by way of a coincidence gate. The dot generators are described in detail below together with the schematic of FIG. 7A. The 2 outputs from the dot generators are tied together and provide the video signal for DOT 1. In the overall case illustrated in FIG. 4, a coincidence gate is proven coupling the vertical and horizontal pulses for each dot to be displayed. The gate output turns into DOT 1 video (unblank) sign. For instance, a sport could also be performed through which one dot is to be positioned over the other and when this is completed one dot will disappear and/or the background will change shade.
It is still one other object of the present invention to allow using a standard Television set for gaming or different activities without the necessity for any sort of inner electrical connection to the Tv set for the introduction of video and/or chroma signals, connections being required to be made solely to the externally accessible antenna terminals. No. 697,798, filed Jan. 15, 1968 and "Television Gaming Apparatus and Method" Ser. The management apparatus has video sign management means mounted thereon for quick access and connecting means are provided for coupling the video signals generated within the management box to the tv receiver. The principal parts of 1 embodiment of a television gaming system configured in keeping with the invention are illustrated in FIG. 1 which is a pictorial view exhibiting a television receiver 10, a control unit 14 and means 12 for connecting management unit 14 to receiver 10. The television receiver 10 employed could be any of the standard commercially accessible models which might be generally used for residence leisure. Heretofore, shade and monochrome tv receivers have been used generally by the home and other viewers as passive devices; i.e., the tv receiver is used solely as a show means for programming originating at a studio.
