Video game equipment system capable of displaying commercial advertisements and method of playing game

Description: TECHNICAL FIELD [Detailed description of the invention]

【0001】

[Industrial application field]

The present invention relates to a game machine system capable of displaying commercial advertisements.

【0002】

[Conventional technology]

With regard to conventional game machines, recently, game machines have become widespread not only in dedicated game corners in the city but also in general households, and along with this, various game software such as automobile racing game software and airplane flight simulator game software have become widespread. Is sold in large quantities.

【0003】

For example, when a car racing game software is started on a game machine, a realistic landscape that faithfully reproduces the actual F1 race track is projected on the display, and the operator can use the operation panel such as Joyce Tech. Each racing car runs on the circuit course according to the instructions given.

【0004】

[Problems to be Solved by the Invention]

However, in the actual F1 race track, commercial advertisements are made on the fences, signboards, advertising towers, and the bodies of racing cars in the background, but in game software, they are actively commercialized accordingly. There are no examples of incorporating advertisements.

【0005】

Currently, as advertisements incorporated in game software, there are only cases where corporate advertisements of the software production company are displayed before, after, or when the scene of the game software is changed (scene change). Yes, there is no example of active commercial advertising in game software. In addition, even if there is an example in which an advertisement is projected in the background, there is no example as a commercial advertisement in consideration of profits, and it is a formal advertisement for faithfully copying the actual scene such as a circuit course. ..

【0006】

Also, once a game software is created, it is rarely changed unless there is a problem with the software. If you don't change the software, even if you put a commercial ad in the background, the ad will become obsolete over time and the ad will not be effective.

【0007】

The motivation for the present invention is that the current private TV broadcasting is operated by commercial (corporate advertising) revenue, and no broadcasting fee is collected from the recipient. Similarly, if commercial advertising can be incorporated into game software such as fences, signboards, and advertising towers beside the circuit course in the background according to the demands of other companies, advertising fee income will be obtained, and as a result, advertising fee income will be obtained. It is based on the fact that the selling price of game software could be lowered or made free of charge. Furthermore, certain game software is usually expected to be used many times, and if the content of this advertisement can be changed or updated at any time, the effectiveness as a commercial advertisement will be improved and the expected advertising revenue will be increased. It is based on the fact that it will be obtained.

【0008】

Therefore, according to the present invention, a game machine of each household is connected to a host computer (controller) via a communication line or the like to form a game machine system, and the game software used in the game machine system is commercialized according to the demand of a company. It is an object of the present invention to provide a game machine system capable of incorporating the above and a game method using the same.

【0009】

A further object of the present invention is to provide a game machine system capable of easily updating commercial advertisements incorporated in game software used in the game machine system, and a game method using the same.

【0010】

[Means for solving problems]

The game machine system according to the present invention is a game machine system including a transmitting side device, one or more receiving side game devices, and a communication line connecting them. The transmitting side device is a main program of game software. The receiving side game device has a storage device that stores fixed data related to the data, a storage device that stores variable data related to commercial advertisement of game software, and means for appropriately switching and transmitting the fixed data and the variable data. It has a storage means for accumulating fixed data and variable data, and by transmitting the fixed data and updated variable data of the game software to the receiving side game device on the transmitting side, an image based on the latest variable data is always produced. Appears in part of the game image.

[Action]

Since the data related to the commercial advertisement of the game software is variable data, the game software containing the constantly updated commercial advertisement can be used by starting the game for the first time by combining this with the main program which is fixed data.

【0011】

[Example]

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Contents of commercial advertisements in game software First, a mode of commercial advertising of the game software used in this embodiment will be described. Figure 1 shows a scene that is displayed on the screen (display) of the display device when the game software of a certain racing game is started on the game machine system, assuming a circuit course and a signboard standing beside the course. It is a figure. On the signboard displayed on the screen of Fig. 1 (a), a commercial advertisement "A" appears on the screen. When the image data of only the part of the commercial advertisement A in the scene of Fig. 1 (a) is replaced with the commercial advertisement "B", as shown in Fig. 1 (b), the commercial advertisement of B is in the same scene as in Fig. 1 (a). Can be done.

【0012】

Figure 2 shows a scene displayed on the display of the display device when the game software of this racing game is started on the game machine system, assuming a part where characters (characters) such as F1 racers are moving. It is a figure. On the screen of Fig. 2 (a), a commercial advertisement with the letter "C" appears on the chest of the character. If the image data of only the commercial advertisement C part of the scene in Fig. 2 (a) is replaced with the commercial advertisement "D", the commercial advertisement D is performed in the same scene as in Fig. 2 (a) as shown in Fig. 2 (b). Can be done.

【0013】

Game software data structure Two types of data structures of game software that can appropriately update commercial advertisements as described above will be described with reference to FIGS. 3 and 4. 3 (a) and 3 (b) show the file structure of the game software in which only the data of the advertisement part in the image as shown in FIGS. 1 and 2 can be replaced (replaced). In the file structure of FIG. 3 (a), files A and C (variable data) of image data to be pasted in the advertising section are added separately from the main program M (fixed data). In this case, the amount of data in the data files A and C is less than 1% of the amount of data in the main program M. Further, in the main program M, an identification code indicating the type of game software, which will be described later in relation to FIGS. 8 to 10, can be inserted as needed.

【0014】

The file structure of Fig. 3 (b) is exactly the same as the file structure of Fig. 3 (a) in the main program M, but the contents of the data file A of the pasted part at address A0 (commercial advertisement A). ) Is changed (updated) to the contents of data file B (commercial advertisement B), and similarly the contents of data file C (commercial advertisement C) at address C0 are changed to the contents of data file D (commercial advertisement D). There is.

【0015】

Explaining the program structure of FIG. 3 corresponding to the examples of FIGS. 1 (a) and 1 (b), the main program M is a racing game game excluding the above-mentioned pasted portion (commercial advertisement portion, variable data). It is the main program M (fixed data) of the entire software, and the data files A and C are the image data (variable data) of the signboards shown in Fig. 1 (a) and Fig. 2 (a), and their contents are commercial. Advertisements A and C are displayed respectively. Further, the data files B and D are image data (variable data) of the pasted portion of FIGS. 1 (b) and 2 (b), and the contents thereof are the commercial advertisements B and D, respectively. The start address of the data files A and C is A0, and the start address of the data files B or D is C0.

【0016】

Using the flowchart of FIG. 4, the game progress of the game software having the data structure of FIG. 3 will be described. (1) When the power of the game machine system is turned on to operate and the main program M is started, the racing game is executed according to the work procedure specified in the main program M (step S41).

【0017】

(2) When the address of the main program M reaches the scene of the circuit course and the signboard shown in Fig. 1 (a), the main program M goes to refer to the data file at the address A0 (S42). If the content of the data file at address A0 is image data A, the main program M generates the circuit course and signboard scenes while capturing the contents of data file A (see Fig. 1 (a)). On the other hand, if the contents of the data file at address A0 are updated and the image data is B, the main program M generates the circuit course and the signboard scene while capturing the contents of the data file B (see Fig. 1 (b)). ).

【0018】

(3) After the circuit course and signboard scene in Fig. 1 are completed, the main program M continues the prescribed procedure (S43).

【0019】

(4) When the address of the main program M reaches the scene where the character shown in Fig. 2 (a) is displayed on the display, the data file at the address C0 is referred to (S44). If the content of the data file at address C0 is image data C, the main program M generates a scene in which the character is displayed on the display while capturing the content of the data file C. On the other hand, if the content of the data file at address C0 is image data D, the main program M generates a scene in which the character is displayed on the display while capturing the content of the data file D.

【0020】

(5) After the scene in which the character shown in FIG. 2 is displayed on the display ends, the main program M continues until the game ends (S45).

【0021】

In this way, by initially using the main program M and the data files A and C, the commercial advertisements "A" and "C" are advertised on the display as shown in FIGS. 1 (a) and 2 (a). .. Then, when the contents of the data file are updated after an appropriate period of time, the main program M and the data files B and D are used to display the data as shown in FIGS. 1 (b) and 2 (b). Updated commercial advertisements "B" and "D" are advertised.

【0022】

The other type of file structure shown in FIGS. 5 (a) and 5 (b) is different from the file structure described in FIGS. 3 (a) and 3 (b), and replaces (updates) the image data of the selected advertisement. Rather, the variable data represents the file structure of the game software with only the selection code that determines which advertisement to select. The file structure shown in Fig. 5 (a) has a structure in which a plurality of advertising partial image data A, B, C, and D to be pasted into the advertising section are preliminarily incorporated into the main program M (fixed data). .. In addition to this main program M, there is a selection code file S (variable data) that has only selection code data, and the content of this selection code file S is a code file Sac that selects image data A and C. It has become. In this case, the amount of data in the main program M is relatively large compared to the amount of data in the main program M in FIG. 3, but the amount of data in the selection code file S is increased by that amount in the updatable data file in FIG. Compared to A and C, it is extremely small.

【0023】

In the case of FIG. 5 (b), the main program M is exactly the same as the main program M in FIG. 5 (a). The selection code file S provided separately from the main program M is different in that it is the content Sbd for selecting the image data B and D.

【0024】

In the examples of FIGS. 1 and 2, the main program M is a racing game game software program excluding the above-mentioned stakeout portion (commercial advertisement portion), and the data A is the data of the commercial advertisement A shown in FIG. .. The data B is the data of the commercial advertisement B, the data file C is the data of the commercial advertisement C, and the data file D is the data of the commercial advertisement D.

【0025】

Using the flowchart of FIG. 6, the game progress of the game software having the data structure of FIG. 5 will be described. (1) When the power of the game machine is turned on to operate and the main program M is started, the racing game is executed according to the work procedure specified in the main routine part of the main program M (step S61).

【0026】

(2) When the address of the main program M reaches the scene of the circuit course and the signboard shown in Fig. 1, the selection code reading is instructed and the code file S is referred to (S62). When the content of the code file S is determined (S63) and the selection code S instructs to select the image data A (S = Sac), the content of the image data A is captured and shown in FIG. 1 (a). Generate a scene of the circuit course and signboard of (S64). Unlike this, when the selection code S instructs to select the image data B (S = Sbd), the scene of the circuit course and the signboard in Fig. 1 (b) while capturing the contents of the image data B. Is generated (S65).

【0027】

(3) In addition, the main program M continues the prescribed procedure (S66). When the address of the main program M reaches the scene displayed on the character display shown in Fig. 2, the selection code reading is instructed and the code file S is referred to (S67). When the content of the code file S is determined (S68) and the selection code S instructs to select the image data C (S = Sac), the content of the image data C is captured and shown in FIG. 2 (a). Generate the scene of (S69). Unlike this, when the selection code S instructs to select the image data D (S = Sbd), the scene shown in Fig. 2 (b) is generated while capturing the contents of the image data D (S65). ).

【0028】

(4) Furthermore, the main program M continues the specified procedure until the end of the game (S71).

【0029】

By using the main program M including the image data files A, B, C and D in advance and the updatable selection code file S, the commercial advertisement A, C or B, D is displayed on the display as shown in FIGS. 1 and 2. Is advertised.

【0030】

Regarding the file structure described with reference to FIGS. 3 and 4, the number of commercial advertisements (variable data) is not limited to A to D, and it goes without saying that a large number of commercial advertisement data can be provided as desired. .. Further, although the variable data has been described as an image data format, it can be provided in a program format such as a subprogram (child program, updatable program) for the main program M (parent program, fixed program). In this case, the main program M jumps to the subprogram at the commercial advertisement display location, and after the subprogram is effective, returns to the next step of the commercial advertisement display location of the main program M again.

【0031】

Game console system used Next, three types of typical game machine systems that can use game software that can incorporate updatable commercial advertisements as described above will be described.

【0032】

First, for the game machine system shown in Fig. 7, the entire game software including the commercial advertisement updated appropriately on the transmitting side, which is a company such as a game software company and a telecommunications company that undertakes commercial advertisement, is prepared, and this game software is used. It shows the configuration of a system characterized by transmitting to a game machine in a home via a communication line. The configuration of this game machine system includes a transmitting side device arranged in a company, a receiving side device arranged in each home, and a communication line connecting the transmitting side device and the receiving side device.

【0033】

The transmitting device stores the controller 2 that controls the transmitting device and the variable data image data A, B, C, D in FIG. 3 or the selection code S (variable data) in FIG. 5, and the disk can be exchanged. Optical magnetic disk drive (MO) 4, hard disk drive (HD-M) 6 that drives the hard disk that stores the main program M (fixed data) of the game software that is fixed data, and hard disk drive (HD) connected to MO4 -S) 8 and one variable terminal M receive fixed data from HD-M6, the other variable terminal S receives variable data from HD-S8, and output by switching control by switching signal 9 from controller 2. Switch means SW10 connected to the fixed terminal, encoder (ENC modulator) 12 that encodes the output data from SW10 according to the communication line 16, and communication device means 14 that outputs the encoded data to the communication line 16. And have.

【0034】

As the communication line 16, ISDN (integrated services digital network), which is well known in this field, can be used.

【0035】

The receiving side devices arranged in the home include a receiver means 18 connected to the communication line 16 and a recorder (DEC) 20 for decoding game software data transmitted via the communication line 16 and the receiver means 18. And a game machine 22. The game machine 22 has a rewritable magneto-optical disk (MO-G) 24 that stores game software transmitted via the communication line 16.

【0036】

The main program M (variable data) of FIG. 3 or 5 is stored in the interchangeable disk of MO4 on the transmitting side. By exchanging the mounted disc, the variable data described in FIGS. 3 and 5 can be updated as appropriate. That is, the content of the commercial advertisement is appropriately updated as shown in FIGS. 1 (a) and 2 (a) to 1 (b) and 2 (b).

【0037】

The main program M (fixed data), which is the fixed data described in FIGS. 3 and 5, is stored in the MD-M6 disk on the transmitting side. The MD-S8 disk on the transmitting side stores variable data transferred from MO4.

【0038】

The operation of the game machine system shown in FIG. 7 will be described. In advance, according to the data transfer instruction (or activation instruction) 3 from the controller 2, the appropriately updated data of the MO4 is transferred to one of the HD-S8s. The main program M is stored in the disc inserted in the other HD-M6.

【0039】

When the game software is started, the switch signal 9 of the controller 2 connects the movable terminal M of the SW10 to the fixed output terminal as shown in FIG. 7, and at the same time, the transfer command (or start command) 5 is sent from the controller 2 to the HD-M6. Emitted. The data of HD-M6 (main program M) is encoded by ENC12 for communication via SW10, and is placed on the communication line 16 from the transmitter means 14. Data is transmitted to the receiving side by the communication line 16.

【0040】

The data transmitted via the communication line 16 is once received by the receiver means 18 on the receiving side. The transmission data encoded for transmission is decoded by DEC20. The decrypted data is stored in the MO-G24 disk in the game machine 22. The main program M is sequentially transferred from the transmitting side to the receiving side, and the transfer of the main program M ends.

【0041】

When the transfer of the main program M is completed, the transfer command (or start command) 7 is issued from the controller 2 to the HD-S8, and at the same time, the switching signal 9 is issued from the controller 2 to the SW10 to change the variable terminal S. Is connected to the fixed output terminal. The variable data stored in the HD-S8 disk is similarly stored in the MO-G24 disk in the game machine 22 via SW10, ENC12, transmitter means 14, communication line 16, receiver means 18, and DEC20. To. When the variable data is accumulated, the game software including the updated commercial advertisement is accumulated in the MO-G24 of the game machine 24.

【0042】

In the game machine system shown in FIG. 7 described above, the transmitting side can appropriately update the commercial advertisement described in FIGS. 1 and 2 by exchanging the MO4 disc.

【0043】

FIG. 8 is a diagram partially showing the configuration of another game machine system, in which a game user purchases game software (main program M, fixed data) with an identification code and commercial advertisement of the game software. It is characterized by receiving sequentially updated data from the transmitting side via a communication line as a part (variable data).

【0044】

This game machine system includes a transmitting side device owned by the company, a receiving side device arranged in the home, and a communication line connecting the transmitting side device and the receiving side device. In FIG. 8, the transmitting side is provided. The equipment is not shown.

【0045】

The communication line 25 is the same as the communication line shown in FIG. 7, and ISDN or the like can be used.

【0046】

The receiving side devices include a system controller (syscon) 30 that controls the receiving side device, a RAM 28 connected to the syscon 30, and a transmitter / transmitter means 26 connected to the RAM 28 and connected to a communication line. Similarly, it has a magneto-optical drive (MO) 38 that is connected to the syscon 30 and exchanges data with the RAM 28. The syscon 30 is provided with a key input converter 32 capable of appropriately converting key inputs such as instructed commands and data input via a keyboard (not shown). Further, it has a demodulator 34 that decodes the data from the RAM 28 under the control of the syscon 30, and an image controller 36 for displaying the demodulated data on a display (display device, not shown).

【0047】

The key input converter 32 can change and match the functions and roles of the input keys of different keyboards between game software to desired functions, and is determined by the syscon 30 when the game software disc is inserted into the MO38. Initially set.

【0048】

The operation of the game machine system shown in FIG. 8 will be described. The game user inserts the disc in which the game software (main program M, fixed data) is written into the MO38 and starts the game software. An identification code that can identify the type of game software is written at the beginning of the main program M used in this game machine system. When the game software is started, this identification signal is transferred to RAM28. This identification signal is once transferred to the host computer on the transmitting side (not shown, corresponding to the controller 2 in FIG. 7) via the transmitter / receiver means 26 and the communication line 25. Upon receiving the identification code, the host computer initiates the transfer of the updated variable data described in FIG. 3 or FIG.

【0049】

On the receiver side, the variable data transferred via the communication line 25 is stored in the RAM 28 via the transmitter / receiver means 26. The variable data stored in the RAM 28 is written and updated in a predetermined variable data area of the game software of the MO38 disk via the connection 37. That is, the user cannot execute the game software unless the variable data related to the updated commercial advertisement is received from the sender, and the variable data of the game software is the latest data or the data intended by the sender each time the game is executed. Will be updated to. The updated game software program is completed by the above operations, and it is preferable that these series of operations are performed as the initial operations of the game software.

【0050】

As for the operation related to the user, the game software data stored in the MO38 is sent to the RAM 28, sent to the image controller 36 via the connection 33 and the demodulator 34, and output on the monitor (display) (not shown). To. In addition, the input from the keys of the keyboard (not shown) is converted as needed by the key input converter 32, and the syscon 30 judges the contents, sequentially obtains the necessary part data from MO38, and RAM28. Rewrite the above data.

【0051】

Yet another game machine system shown in FIG. 9 is a system in which a game user purchases game software like the game machine system of FIG. 8, but the variable data in the game software is updated via broadcasting. It is a figure which partially shows the structure of the system which is characterized by this. Broadcasting is one-way transmission from the transmitting side to the receiving side, and it is very low-priced. In this respect, the game machine system shown in Fig. 8 uses a line capable of two-way communication such as ISDN, which is relatively expensive. It's different from what you're doing. In this game machine system, the variable data of FIG. 3 or FIG. 5 is continuously transmitted by using a broadcasting line.

【0052】

This game machine system includes a transmitting side device owned by a company, a receiving side device arranged in a home, and a broadcasting line connecting the transmitting side device and the receiving side device. In FIG. 9, the transmitting side is provided. The equipment is not shown.

【0053】

The receiving side devices include a receiver means 38 that receives variable data sent from the transmitting side via the antenna 53, an HD drive 40 that stores the data of the receiver means 38, and fixed data and variable data for image output. It has a RAM 42 that temporarily stores data, a demodulator 44, and an image controller 46.

【0054】

The receiver means 38, the HD drive 40, the RAM 42, and the demodulator 44 are controlled by a system controller (syscon) 48 that controls the receiver side equipment. A CD-ROM drive 52 into which a game software disc purchased by a game user is inserted is connected to the syscon 48. Further, as in FIG. 8, the syscon 48 is equipped with a key input converter 50.

【0055】

The operation of the game machine system shown in FIG. 9 will be described. The user inserts the disc containing the purchased game software into the CD-ROM drive 52. The main program M (fixed data) of the game software is stored in this CD-ROM. When the game software is started by the CD-ROM drive 52, the software identification data (identification symbol, different identification symbols depending on the type of game software) stored in the head part of the game software is once connected via the connection 41. Sent to RAM42. The soft identification data of the RAM 42 is sent to the syscon 48 via the connection 45. The syscon 48 determines the channel number on which the variable data (changed data) of the soft identification data is broadcast corresponding to the soft identification data, and connects the channel number and the soft identification data to the receiver means 38 via the connection 37. Instruct.

【0056】

Please refer to Fig. 10. One or two or more channels are prepared for broadcasting on the transmitting side. In the case of a plurality of channels, for example, it is assumed that there are a channel G (FIG. 10 (a)) and a channel H (FIG. 10 (b)).

【0057】

In channel G, after sending the soft identification data J, two change data (J-1) and (J-2) are sent. Next, after sending the software identification data K, three change data (K-1), (K-2), and (K-3) are sent. The amount of software identification data is constant, but the type and amount of change data differ depending on the game software. Since the timing to start the game software is arbitrary, if the timing to send one game software is too free, the schedule screen will appear before the change data is updated, so in channel G, after the change data of the software identification data K, again It repeats the operation of sending the change data (J-1) and (J-2) of the software identification data J. Channel H also broadcasts change data of software identification data P, Q, and R.

【0058】

If the software identification data of the game software purchased by the user is, for example, "Q", the receiver means 38 is set to the channel H correspondingly. In the broadcast of channel H, variable data (changed data) of various game software including software identification data Q is broadcast.

【0059】

Returning to FIG. 9, the receiver means 38 starts from the moment when the change data Q-1 corresponding to the software identification data Q is sent in the broadcast of the channel H, the change data Q-1. Is stored in the HD drive 40. At this time, the updated commercial advertisement data is stored in the HD drive 40, and the main program M is stored in the disk inserted in the CD-ROM drive 52. The game software is completed and executed by these two data.

【0060】

The Syscon 48 starts the main program M, which is the fixed data of the CD-ROM drive 52, and reads it into the RAM 42, while reading the commercial advertisement, which is the variable data, from the HD drive 40 into the RAM 42 and executes the game software. The game software data of RAM42 is displayed on the display (not shown) via the demodulator 44 and the image controller 46.

【0061】

The game software cannot be executed by the main program M of the CD-ROM drive 52 alone. For this reason, the updated commercial advertisement will always be visible to the game user, and the price of the game software will be kept low or free of charge due to the income of the commercial advertisement.

【0062】

FIG. 11 is a conceptual diagram of the game machine system described above, in which a plurality of home game machines are connected.

【0063】

The effects of the above-described examples will be listed below. (1) Commercial promotion activities within the game software will be possible, and the software will be cheaper or free of charge. (2) Enable the latest advertising activities and always enable new advertising activities. (3) In addition to communication, commercial advertising by broadcasting will also be possible. In this case, since the channel is set automatically, the user can operate without being aware of it at all. (4) Even in the game machine system that uses the file structure shown in Fig. 5, the usage time of the communication line is short because the update data is small. (5) Since the game machine system shown in Fig. 9 has little update data, one broadcasting channel can support a number of software. (6) In the game machine system shown in Fig. 9, the correspondence data between the channel and the software is also sent by broadcasting, so it is possible to respond according to the release of the software.

【0064】

[Effect of the invention]

According to the present invention, a game machine of each household is connected to a host computer (controller) via a communication line or the like to form a game machine system, and the game software used in the game machine system is commercialized according to the demand of a company. It is possible to provide a game machine system capable of incorporating the above and a game method using the same.

【0065】

Further, according to the present invention, it is possible to provide a game machine system capable of appropriately and easily updating commercial advertisements incorporated in game software used in the game machine system, and a game method using the same.
