fig1 is an external view of a video game system and a historical event . an historical event 11 takes place . for example , the event may be a world cup soccer game , or an american football game . in a more specific example , the event may be the occurrence of a new yearly completion percentage , or other performance statistic , of a specific quarterback in a specific professional american football game . a datum 17 relating to the historical event 11 is recorded on a computer readable medium known as a network server 14 . a game machine 20 is coupled to the network server 14 . the game machine 20 downloads the datum 17 , which may , for example , represent a quarterback &# 39 ; s completion percentage , a basketball player &# 39 ; s free throw percentage , or any other outcome of a realistic event . the datum 17 is then used to play a video game , which is displayed on a monitor 24 . a user 28 plays the video game using controller 30 . in this way , the user gets to play a video game the more accurately simulates the real world . for example , a datum representing a quarterback &# 39 ; s new completion percentage is loaded into memory ( not shown ) in the game machine 20 . then , the user 28 can play an american football video game with current statistics . this makes the video game more enjoyable to the user , adding increased realism . as real life professional players &# 39 ; performances change , users can still play with statistically accurate players . fig2 is a block diagram of a video game system . the video game machine 20 incorporates a central processing unit ( cpu ) 32 and coprocessor ( cp ) 34 . the cp 34 includes a bus control circuit 38 for controlling buses , a signal processing unit ( spu ) 40 for performing polygon coordinate transformation , shading treatment , etc ., a display processing unit ( dpu ) 45 for rastorizing polygon data into an image to be displayed and converting the data into a data from ( dot data ) stored on a froame memory . the cp 34 is coupled to a cartridge connector 50 for detachably mounting with a rom cartridge 52 , a disc drive connector 54 for detachably mounting with a disc drive 56 , and a ram 58 . also , the cp 34 is connected with an audio signal generating circuit 61 for outputting a sound signal to an audio output device 62 , processed by the cpu 32 , and an image signal generating circuit 64 for outputting an image signal to a display 65 . further , the cp 34 is coupled with a controller control circuit 67 for serially transferring operational data for one or a plurality of controllers 70 a - 70 d and data for a ram cartridge 73 for extension . a modem 72 is coupled to the bus control circuit 38 . the modem 72 is also preferably coupled to the internet ( not shown ). as discussed with reference to fig1 , a server coupled to the internet stores performance , visual image and audio parameters . the modem 72 couples to the server and downloads a parameter for play in the video game . the cpu 11 sends a signal through the bus control circuit to initialize the modem 72 and control the modem 72 to download the parameter . preferably , the parameter is stored in ram 58 for play of the video game , as discussed below . it will be understood by those of skill in the art that other configurations of video game machines are possible . for example , the cpu ii and the cp 34 , or portions of the cp 34 , may be incorporated as one component . also , for example , ram 58 , may be divided into more than one memory element , or other types of memory elements may be included . referring now to fig3 , a block diagram of a video game system 79 is shown . a data server 82 is coupled to a network 85 . the network may be , for example , what is commonly referred to as the internet , or , alternatively , the network 85 may be another type of network , such as a local area network ( lan ). the data server 82 stores information for use in video games . advantageously , new statistical results or parameters can be stored on the data server 82 . for example , when a real professional athlete changes a performance rating , the changed performance rating can be stored on the data server 82 . for example , when a professional baseball player changes his batting average , the changed batting average can be stored on the data server 82 . or , as a second example , if a professional american football quarterback changes his completion percentage the changed completion percentage can be stored on the data server 82 . this allows a video game player to play a video game with the new statistics . the changed statistic may be stored as the actual number that the statistic represents . for example , if a batting average goes from 0 . 275 to 0 . 278 , then the number 0 . 278 may be stored on the data server . or the new statistic may be stored on the data server as a parameter of a video game . the parameter can then be used to affect how the video game character interacts with the video game environment . referring again to fig3 , the user ( not shown ) plays the video game by entering inputs through a user interface 87 . the user interface 87 may be , for example , a video game controller ( not shown ). the user interface 87 is coupled to a video game machine 90 , which may be a video game machine 20 , as shown with reference to fig2 . the video game machine 90 , is coupled to a ram 95 and a local memory 99 , preferably a read only memory ( rom ). the ram 95 is used for storing data and rules ( described later with reference to fig4 ) from the game medium 103 . advantageously , the parameter is also stored on the ram . thus , the video game is played with the changed statistic . advantageously , a video game character , such as , for example , an american football quarterback , will play more realistically based on the video game character &# 39 ; s real life performance , such as , for example , a completion percentage . the video game machine is coupled to a modem 107 for coupling to the network 85 . the parameter is downloaded by the video game machine 90 from the data server 82 by means of the modem 107 and the network 85 . as will be understood by those of skill in the art , the modem 107 may be incorporated as part of the video game machine 90 , or a separate component . fig4 is a block diagram of a game medium , preferably a rom 109 . the game medium may be , for example , a compact disc ( cd ), a digital video disc ( dvd ), or a cartridge . the rom 109 includes many rules and parameters for the video game . rules 111 are stored on the rom 109 . the rules 111 are shown as rule 1 , rule 2 , rule 3 , etc . the rules govern how the game is played and displayed on the user interface . advantageously , the rules can be updated to match the rules of the real world . there are also other parameters stored on the rom 109 . for example , stadium parameters 113 may be stored . for example , the game may display wrigley field for play by the chicago cubs and fenway park for play by the boston red socks . for example , the ivy on the homerun wall of wrigley field is green and flourishing during certain parts of the year , such as from may to july . during april , august and september , the ivy is browner . the color of the ivy shown in a baseball video game showing wrigley field can change based on the time of the year that the video game is played . as another example of how realism can be increased , new memorials to great players can be implemented in the video game stadiums . for example , in 2002 , ted williams &# 39 ; number , “ 9 ”, was displayed in the leftfield grass of fenway park after the start of the season . baseball video games were already produced . so the video game fields did not have the number on the field , failing to duplicate real life . now , the field can be changed to match real life after the game is produced , sold and played in the user &# 39 ; s home . referring again to fig4 , referees 115 may be stored . referees &# 39 ; appearances and performance may be stored . for example , some referees in basketball call technical fouls frequently . some referees rarely call technical fouls . parameters can be stored regarding the individual referees that simulate these real life differences . team statistics and other parameters can also be stored , such as , for example , the city , owners , trainers , coaches , players , etc . for example , mike bibby of the sacramento kings , during the 2001 - 2002 regular season averaged 13 . 7 points and 12 . 3 shots attempted per game . in the playoffs of the same season , he averaged 20 . 2 points and 16 . 1 shot attempted per game . these improved playoff statistics can now be downloaded . a video game player can play a basketball video game with a mike bibby character incorporating the better performing real world mike bibby . as another example , the 2000 - 2001 chicago bears &# 39 ; opponents scored an average of 22 . 2 points per game with an average of 114 . 2 rushing yards per game . the 2001 - 2002 chicago bears &# 39 ; opponents scored an average of 12 . 7 points per game with an average of 82 . 1 rushing yards per game . this change was not reflected in video games played during the 2001 - 2002 season . at that time , the newest video games reflected the statistics from the 2000 - 2001 season . thus , the chicago bears on the video games played poorly , whereas the chicago bears on the real football field played very well . this dichotomy between video game and real life is frustrating to many video game players . fig5 is a block diagram of the players stored in rom . player 1 , player 2 , player 3 and several other players are shown . under each player , several statistics are shown . for example , if the video game is basketball , statistic 1 may be a player &# 39 ; s field goal percentage . statistic 2 may be a free throw percentage . statistic 3 may be blocks per game . one skilled in the art will appreciate that the number and type of statistics stored will very with the game and with the way the video game designer choses to design the game . fig6 is a block diagram of a ram 135 used to store game parameters for play of a video game . ram 135 may be used to store game parameters as are ram 58 and ram 95 . preferably , items are loaded from rom 109 into ram 135 . preferably , all of the rules 111 are loaded into ram at 138 . however , only one stadium is loaded from rom to ram . also , only two teams , shown as team 1 and team 2 are loaded . as discussed with reference to fig1 - 3 , above , a new parameter is downloaded from the server and stored in ram 135 . preferably , the new parameter is stored in ram in addition to the parameter as loaded from rom . referring now to fig7 , a flowchart is shown . in step 221 , the method starts . in step 224 , it is determined whether auto update is enabled . if auto update is enabled , the method continues by going to fig8 , as shown at step 227 . if auto update is not enabled , the main menu is displayed at step 230 . in step 232 , a user chooses to start a game or request an update , at step 232 . in step 234 , it is determined whether the user requested an update . in step 236 , the method continues by going to fig9 , if the user did not choose to update the video game . if the user did choose to update the video game , the method continues by going to fig8 , at step 238 . referring now to fig8 , in step 241 , the cpu initializes the modem . in step 243 , the modem establishes a network connection . next , in step 245 , the cpu sends a request for data to the data server . at 247 and 249 , the data server sends the requested data to the cpu . advantageously , the requested data may be updated , or changed , statistics for playing a more realistic video game . for example , as mentioned above , the user may be requesting updated batting averages for game characters in a profession baseball video game . or , to continue the example from above , the video game player may be requesting a newly established completion percentage for an american football quarterback . preferably , the request is for all the new statistics resulting from a real game that has already been played , or from a plurality of games . referring again to fig8 , at step 250 , the cpu receives the requested data and stores it in local memory 254 . in step 251 , the cpu disconnects the modem from the network . next , at step 253 , the user is prompted that the data transfer is complete . the main menu is displayed at step 255 , and the method continues to fig9 for play of the game . in fig9 , a flowchart is shown for the play of the video game . at step 265 , the game starts . next , at step 270 , the cpu loads the game engine 275 from the game medium 280 into ram 285 . next , at step 290 , the cpu loads the requested data 295 from local memory 300 into ram 285 . the requested data 295 is preferably the changed statistics requested by the user and stored in local memory as shown in fig8 . this way , updated statistics , such as new player performance parameters resulting from current , real professional games can be used to play a more realistic video game , as shown at step 305 . fig1 is a block diagram showing a portion of a flow diagram for authenticating a user of a video game . at step 334 , a cpu initializes a modem . the modem connects to a network at step 337 . the game machine displays a login / sign - up screen at step 340 . the user selects either to sign up or login in at step 342 . if the user selects to login , the next step depends upon whether an authentication code ( ac ) is required , as shown at step 344 . if no ac is required , the cpu sends the login data to the server at step 346 . the flow then continues at fig1 . alternatively , an ac may be required by the network , as shown at step 348 . this allows the network to verify that the user has a proper authentication code . for example , the authentication code may be provided at sign - up ( described with respect to fig1 ) by the network to the user . this way , the network administrator can verify that the user is a paying user . as another example , a new authentication code may be provided on a periodic basis , such as , for example , monthly . thus , if a user is paying on a monthly basis , correct authentication is only available if the user &# 39 ; s dues are current . as yet another example , the ac may be associated with a specific game machine by either the network or the cpu . this allows for security for preventing portability of ac &# 39 ; s from one game machine to another . referring again to fig1 , if authentication is required , it depends whether the ac is auto - sent or not , as shown at step 351 . if the ac is auto - sent , the process continues at step 346 . if the ac is not auto - sent , the user enters a user verification code , at step 354 . at step 357 , the cpu compares the user verification code to a game machine authentication code . if the user verification code matches the game machine authentication code , at step 360 , the process continues at step 346 . as stated in step 346 , the login data 363 is stored at a network server 366 . next , the process continues at fig1 . fig1 shows a portion of a process for authenticating a video game user , continued from fig1 . at step 369 , the server attempts to authenticate the login data and any ac present . the ac may include a user verification code , to verify that the user is authorized to receive updated game parameters . also , the ac may include a code identifying a specific game machine . this identifying code may , for example , be a serial number from the game machine . alternatively , the identifying code may be a code assigned by the network administrator to the game machine at sign - up ( described with respect to fig1 ). further , the network administrator may verify that the identifying code , the verification code , and the user login data all match . the verification code may be a password . at step 372 , the network checks whether the login data and any ac is authenticated . if the login data and any ac are authenticated , at step 376 , the server sends a menu of available data to the game machine . then , at step 384 , the cpu displays the menu to the user and continues to fig1 . if the login data and any ac are not authenticated at step 372 , the server sends a failure message to the cpu , at step 380 . the cpu displays the failure message to the user , at step 384 . preferably , the cpu next displays the login / sign - up screen to the user again . the process returns to the beginning of fig1 , at step 334 . fig1 is a flow diagram showing a process for signing up a new user of a video game with downloadable statistics . in step 390 , the cpu displays , a sign - up screen . in step 393 , the user enters the user &# 39 ; s name and chosen password , and possibly other identifying information , such as a birthdate , address , etc . in step 396 , the process depends upon whether the ac is auto sent . if the ac is auto sent , the cpu sends the sign - up data 404 to the server 408 in step 400 . in step 412 , the server sends account options 416 to the game machine . in step 420 , the cpu displays the account options to the user . in step 424 , the user selects what type of account the user chooses . in step 428 , the cpu sends the users choice of account type to the server . for example , the user may choose to pay for downloads of new game parameters on a monthly basis . as another example , the user may choose to pay for downloads of new game parameters for an entire sports season . or , as yet another example , the user may choose to pay for downloads of new game parameters on a pay per use basis . other business models will be apparent to those of skill in the art . in step 432 , the server verifies the information , creates an account and sends a menu of game data to the game machine . in step 436 , the cpu displays the menu to the user . next , the process continues as shown in fig1 . alternatively , if in step 396 , the ac is not auto sent , the user enters an ac , in step 440 . in step 444 , the cpu compares the user input ac with the game machine authentication code . in step 446 , the cpu determines whether the user input ac matches the game machine ac . if not , the process continues at step 448 and the cpu displays an error message to the user . if the user input ac matches the game machine ac , the process continues at step 400 . fig1 is a flow diagram showing a download process of a new game parameter . in step 450 , the user selects a set of desired game parameters . for example , the desired parameters may comprise a complete set of new parameters for all teams in the game . as another example , the desired parameters may comprise the results of a single sports game for a single team . in step 453 , the cpu sends the request to the server . in step 456 , the process depends on whether the game machine requires an authentication code . in step 459 , the server sends the requested parameters to the cpu . in step 462 , the cpu stores the new game parameters in local memory 465 . alternatively , if in step 456 , the game machine requires an ac , the process continues to step 468 . in step 468 , the server attaches account information and the ac to the parameter . in step 471 , the server sends the parameter to the cpu . in step 474 , the cpu compares the ac with the game machine ac . in step 476 , the game machine determines whether the ac sent by the server matches the ac stored on the game machine . if there is no match , the cpu displays an error message . if there is a match , the cpu stores the data at step 479 in local memory 465 . the data , or new game parameters , can then be used for play in a game with quantifiably increased realism . fig1 is a flow diagram showing game play in a case in which an ac is required . in step 490 , the cpu displays a game menu . in step 495 , the user selects to load saved data 500 , which has been stored in local memory 505 . in step 510 , the cpu reads data from local memory . in step 515 , the cpu compares an ac associated with the data to the game machine ac . in step 520 , the process determines whether the ac associated with the data is the same as the game machine ac . if they don &# 39 ; t match , the cpu displays an error message in step 535 . if they match , the cpu loads the parameter data into ram 525 in step 530 . then , the new game parameters are used for play in a game with quantifiably increased realism .
a system and method for updating parameters of a video game is provided . as events occur in the real world that may influence a game attribute , a parameter is recorded on a server . a video game player may connect to the server and download the parameter . the parameter is stored by the video game and changes an attribute of the video game . thus , for example , the new performance characteristics of the rising star may be recorded on the server as improved performance parameters . when these parameters are downloaded by the video game player , the video game incorporates the star - like qualities of the rising star .
