Description

TELEPHONE ACCESS VIDEO GAME DISTRIBUTION CENTER
BACKGROUND OF THE INVENTION
2
3
This invention relates to a home computing element
5 capable of establishing a digital, interactive communications r system providing a plurality of subscribers access to a
7 plurality of video games stored in a plurality of remote game
8 storage centers. It also provides for the use of a standard
9 television receiver for video and audio, and contemporary
10 input devices to interact with the software program,
11 including video games. A bi-directional telephone link is established between the home computing element and a remote
12
13 game storage center to access the desired game, and a
14 television broadcast channel used un i-d i rec ionally to
. ,. transmit the game software programs.
Much is known about video gaming devices for the home.
16 Presently, all require non-volatile game cartridges to store 17 the game software programs, and use known color graphics 8 circuits along with synthesized audio techniques. GAme 9 cartridges are relatively expensive to purchase, and once 0 they are used for some time, they are used rarely thereafter. 1 This has led to the prolifera ion of video game rental 2 outlets as individuals express that they wogld rather have 23 variety than ownership, and would also rather make a shorter 24 and less expensive commitment. 25
Prior art patents representing known communication or 6 subscriber systems are represented in the U.S. Patent 7 4,829,372 to HcCal ley wherein a digital, interactive 8 communication system is accessible to a plurality of 9 subscribers who can select any of a plurality of pre-recorded 0 video/audio presentations for viewing on a conventional television set. The system includes a converter tuned to a
2 channel for monitoring a digital stream of information including digital packets representative of video/audio
Δ presentations selected by the indi -v>idual subscribers. A
5 subscriber is housed within the apparatus supplied the
5 individual subscriber and the subscriber server receiving
7 uniquely addressed digital packets converts the received
8 packets into NTSC-compatible analog formatted video/audio g presentation for transmission to the requesting subscriber. tø In addition, Abraham, 4,567,512 and 4,590,516, discloses
^1 a system controlled through conventional telephone networking 2 in conjunction with a home controller that contains a
,3 micro-processor and incorporating a telephone interface which
14 allows a subscriber to request a given program which is
15 available on a pre-schedul ed time basis. Abraham does not
16 disclose digital transmissions. In addition, Abraham
,- discloses in U.S. Patent 4,521,806 signal traffic paths being
18 established for telephone communication and cable program 19 transmission in a basic subscription broadcast system. The 20 program material is stored at a library broadcast station in 21 analog form and is digitized and time compressed after readout for transmission to the subscribers along the cable 22 23 paths,
Other patents demonstrating the prior art of the same
24 subject matter include Pocock et al., 4,734,764; Clark et 25 al.,. 4,761,684; and Gordon, 4,763,191. 26
In addition to the above, the U.S. Patent to Harrison, 27 4,584,603, discloses an amusement and information system for 28 use in a closed environment such as on airlines wherein an 29 entertainment terminal including a keyboard and video display 30 assembly is available for use by the occupant and is , structured to provide access to video games as well as movies
2 and other selected information.
2 Although it is well known to use a bi-directional
4 telephone link, as evidenced by the above-noted patents, to
5 access audio and video information hat is transmitted as a g related but independent television broadcast channel, it is η apparent that a need exists for the transmission of Q executable computer software program code representing video
9 games using a television broadcast channel to reach a 0 plurality of subscribers and act upon individual requests.
^ It is an object of this invention to provide a vehicle
, 2 whereby a plurality of video game software programs are made
,3 available substan ally upon demand and upon request to
^jj individual subscribers on a "pay-per-play " basis with a
^5 minimum of subscriber overhead. Another object is to provide
16 a home computing element that provides the means to utilize ,η said software programs, including video games, from within
,o the residence and under subscriber control using contemporary ,u game control devices.
20
21 Summary of the Invention
In accordance with the system of the present invention,
22 any of a plurality of individual subscribers may request a 23 video game stored in a software program library at a remote 24 location utilizing a home computing element or assembly to 25 establish a bi-direc ional telephone communication link with 26 a remote game storage center to access the services offered. 27
The remote game storage center acknowledges the request and 8 establishes a bi-directional channel of communica ions. The 9 home computing element transmits a unique identi ication 0 code, the game select code, the existence of a previously , loaded game software program and any mode commands. During
2 this time, the display on the home computing element shows
3 the status of the operation in progress. If the . homecomputing element cannot establish communications with
5 the remote game storage center, it will retry several times
6 before dropping the line and indicating a failed η communication attempt to the subscriber. g While maintaining communications with the home computing
9 element, the remote game storage center logs the time,
10 telephone number, identification code, the operating mode
11 and the desired game selection of the requesting home
12 computing element. If the selected game is already resident
13 in the home computing element, the remote game storage center •,. transmits an authorization code to the home computing element ,c effectively enabling the software program, and drops the
16 telephone line. A game software program is not transmitted 17 in this case, but if the selection is not in the home 18 computing element memory, the remote game storage center 19 transmits the encoded video game software program and the 20 home computing element identi ication code as a digital bit 21 stream of information over a television broadcast channel. The telephone line is maintained active until all tasks have 22 been completed. 23
The home computing element requesting the game may 24 receive the video game software program only after 25 identification code validation occurs.- This prevents 26 unauthorized use by others. Once reception of all the 27 software data has been successfully completed, the home 28 computing element acknowledges receipt to the remote game 29 storage center and drops the telephone line. The encoded 30 software program is decoded and is enabled to be used. The ^ subscriber is told through the display that the game is ready
2 for use. All of these actions occur in a very short period
3 of time.
. The home computing element offers the subscriber th
5 means to interact with the game using contemporary gamin control or input devices. The game may be played as man times as desired. Each time the subscriber restarts the game, a telephone link is established with the remote game Cf storage center for billing and au horization for use before
10 the game may be used. The software program remains in memory
11 until either power is removed or a new software program is 12 loaded. Even though a program may be resident within the 13 home computing element, its use is restricted unless 14 authorization is issued by the remote game storage center.
,c The remote game storage center always maintains an activity
16 log for each subscriber which is used for billing. 17

The 19 software program representing the selected video game is 20 retrieved from a permanent storage library by a computer _, facility at the remote game storage center 60 and transmitted
22 typically to a CATV head 92 as an encoded stream of digital data in NTSC compatible format as at 70. The signal is then 23 broadcast through the CATV network along with pre-recorded 24 video programming to all cable subscribers. All cable 25 subscribers may view the pre-recorded video programming 26 portion. However, only the specifically requesting 27 subscriber locations or home installations containing the 8 requesting home computing element 10 can receive, decode and 9 use the video game software programs which have been 0 selected. 8
The RF video signal is received from the distribution cable 71, is processed and the resulting, decoded software program stored by the HCE 10 and is then enabled for use by the subscriber in conjunction with display at the conventional television receiver 73. The desired gaming control facilities as at 12 are also usable for subscriber interaction with the video game software program. All billing for use of the subscribed video games is performed au omatically by the computer facilities of the remote game storage center 60 and the information is transmitted over the telephone lines 74 to the main office or headquarters 90 (see Fig. 1). The headquarters 90 may also request other specific information such as but not limited to diagnostic test results from the remote game storage center 60 and may send commands and/or software programs that may be executed by the computer facilities maintained within the remote game storage center 60. Again with reference to Figure 2, a preferred embodiment of the home computing element or assembly 10 encompasses an alphanumeric display 13 to demonstrate or display messages. In addition, a keyboard for subscriber interaction, for example, to enter game selection and commands are represented and includes numerical keys collectively referred to as 24. In addition, commands may be entered into the system by use and considered a part of the home computing element 10. In operation, the subscriber first uses the numeric keypad 15 further utilizing any of the numerical keys to enter the code number for the video game programs selected off the aforemen ioned published menu previously provided. The clear key 16 is used to correct any data entry errors. Once the entire number is entered the enter key 17 is pressed and the home computing element 10 responds by displaying the selections on the display 13. The dial key 18 is then pressed to call the remote game storage center 60 and transmit the proper home computing element 10 identifica ion code and game selection number one by virtue of telephone line 74. The game software program is received by the home computing element 10 where it is decoded and stored. The display 13 indicates that a game is loaded and ready for play. The game is started by pressing the start key 23 and paused at any time by pressing the appropriate pause key 22. Pressing this key again serves to restart the game. The TV/game key 21 may be pressed to switch to view standard programming on the television receiver 73 overriding the game display and audio. The video game software program may be permanently stored in a removable, non-volatile memory card 25 by ensuring that a card is placed in the ide slot as appears in Figure 2. A one time purchase charge will be billed, but the game may be played as often as subscriber likes using the card 25 without incurring additional costs.
Referring to Figures 5 through 12; Figure 5 demonstrates a flow chart depicting the operational logic encompassing the remote game storage center. Figure 6 is a flow chart demonstrating the task performed by an executive program encompassed -within the home computing element 10.
Figure 7 is a flow chart showing the functional aspects of a command processor defining a portion of the home computing element 10 shown in detail in Figure 2. Figure 8 and Figure 9 is a flow chart of a dial-up routine (DIAL) which is invoked by the command processor (Fig. 7) of the home computing element 10. Figure 10 is a flow chart demonstra ing the functions performed by the game storage card 25 programming routine (PROG) which is invoked by the command processor (Fig. 7) of the home computing element of Figure 2. Figure 11 is a flow chart of a reset game routine (RST) which is invoked by the command processor whose flow chart is shown in Figure 7. Figure 12 is a flow chart demonstrating the start game routine (STRT) invoked by the command processor (Fig. 7) of the home computing element 10.
10 Figure 3 is a detailed, internal block diagram which
11 shows all of the major circuits contained in the home 2 computing element 10. The home computing element 10 is based 3 on a micro-processing unit 30 which acts as the overall
14 controller. The micro-computer 30 operates as dictated by
15 the executive program which is stored in the ROM 31. The lg flow charts as set forth in Figures 5 through 12 and as
17 explained in greater detail above illustrate the operations 18 related to the executive program in more specific detail. 19 Data areas required by the executive and external program 20 areas reserved for the use of downloaded video game software
2i programs reside in random access memory (RAM) 32. The memory
22 areas in RAM are volatile and will lose their contents if 23 power is removed, therefore, an electrically erasable programmable read only memory (EEPROM) 33 provides 24 non-volatile storage for such data as the telephone number of 25 the remote game storage center 60 serving the subscriber, the 26 home computing element 10 identification code, and other 27 information that must be retained if power is lost. 28
As shown in Figure 3, several circuits are provided to 29 interface the micro-controller or micro-processor unit 30 to 30 the outside world referred to herein as peripheral devices. H A telephone link is provided by a universal asynchronous receiver/transmitter (UART) 34 whose digital output keys two distinct audio tones that are transmitted to the telephone line, along with "hand-shaking" information by a modem interface 35. The modulated outputs are transformer coupled to the telephone line 79. All telephone communications, i nclud ing au tomat ic dial-up are handled by the micro-processing unit 30 utilizing this circuitry. The keyboard 42 status is read by the micro-processing unit 30 through a peripheral interface adapter 40 which is capable of interfacing with digital inputs and outputs only. A contact based game control adapter is interfaced to the micro-processing unit 30 through the peripheral interface adapter 40, but potentiometer based input devices, such as some joy-sticks and trackballs, are interfaced through an analog to digital converter (ADC) 39 which is capable of converting the analog signals provided by the input device to their numeric or binary representations required by the micro-processing unit 30. The display module 13 (see also Figure 2) containing the internal electronics necessary to display alpha/numeric characters, interfaces directly to the micro-processing unit 30 data bus 50. The display is where all the sys em status messages a e displayed to the subscriber. Again with reference to Figure 3, the incoming broadcast channel 51 is monitored for game software programs. The signal is demodulated by an RF demodulator 36 and then passed to a digital signal processor 37 which samples the signal, converts it to digital data, processes the information and then makes it available to the micro-processing unit 30. The digital signal processor 37 is a single-chip computer 1 tailored to the task of obtaining a digital representation of
2 analog signals and digital processing at a very fast rate; 2 currently up to 33 million operations per second. The digital signal processor 37 acts as a co-processor operating
5 under the control of its own custom software program written g in a machine specific computer language.
7 The NTSC compatible signal 52 that is ultimately
8 connected to the television receiver 73 contains all of the g video and audio information associated with the game. the
10 video is generated by the graphics generator circuit 45 which 1 is itself another co-processor, while the sound generator 44
12 creates all of the audio and is directly controlled by the 2 micro-processing unit 30. The output signals are used to
1 modulate carriers with the video 47 and audio 46 modulators
15 and then mixed with a RF combiner 48 whose output is a NTSC
16 compatible television signal 52 that drives the television 17 receiver 73. The TV/GAME relay 49 is controlled by the 18 micro-processing unit 30 and connects the output of the 19 combiner 52 to the video output jack. The relay 49 responds 20 to the activity of the TV/GAME key 21 as an alternate action 21 device. 22 With reference to Figure 4, the remote game stored 23 center 60 (Fig. I) includes a thirty-two bit desk top computer 61 to perform all required processing, storage and 24 control functions. Storage for the dedicated and game 25 software is provided by a hard disk 63 with fast access times. 26 The computer 61 is initially loaded from the magnetic tape 27 cartridge drive 64 by a utility invoked from the 1.44 28 megabyte floppy drive 62 containing the appropriate disk. 29 The utility reads the software programs from the tape drive 30 64 and stores it on the hard disk 63 for fast, random access I
I
1 of files. The flow chart illustrating the major tasks
2 performed by the executive program of the remote game stored
3 center 60 is shown in Figure 5.
4 The computer 61 is also responsible for controlling
- telephone access to resident services. A plurality of
- telephone lines 79 are routed by a telephone switching
7 controller 67 to several modems 66 which convert the FSK
8 telephone signals 80 to RS-232 digital, serial data 81. This
9 data is read and buffered by a RS-232 multiplexer/bu fer 65 10 which allows high speed data transfers through a parallel
11 interface 87 to serve a large plurality of modems 66. These
12 are all bi-directional data paths allowing the computer 61 to
13 receive and transmit data through the telephone. The
14 computer 61 responds to different messages f rom the
15 subscriber and other messages from the main office or
16 headquarters dealing with game selections to be broadcast,
17 types of service being provided, diagnostic test results, and
18 billing information and other relevant information requests
19 or command messages.
20 The last major task performed by the remote game storage
21 center 60, computer 61 is the transmission of the game
22 software programs that will ultimately execute in a home
23 computing element 10. The software is output by the computer
24 61 as a digital bit stream 85 which is modulated and mixed
25 with the s ignal coming f rom the video casse t te
26 recorder/player (VCR) 68, or other broadcast source by an RF
27 modulator 69. The resulting output 70 is then typically
28 delivered to a CATV head end 92 for distribution. The VCR 68
29 contains standard pre-recorded programming for broadcas , and
30 is controlled by the computer 61 through a series of control lines 83. It is therefore to be understood that the following claims are intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language, might be said to fall therebetween. Now that the invention has been described,
