Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing system based on unidirectional mass communication, and more particularly to audio broadcasting when audio broadcasting is performed using a unidirectional mass communication system such as FM broadcasting and broadcasting satellites. The present invention relates to an information processing system by unidirectional mass communication that provides a new broadcasting service by adding control data and transmitting it.

[0002]

2. Description of the Related Art With the advancement of communication technology, data communication for transmitting and receiving desired data individually and bidirectionally using a public line has been widely used. In addition, as a unidirectional mass communication system, an FM broadcast in which audio such as music is FM-modulated and transmitted, and a satellite broadcast in which a composite video signal in which audio and video are combined are transmitted are known.

[0003]

[Problems to be Solved by the Invention] Since bidirectional communication using a public line is charged in proportion to communication time, communication cost becomes high. For example, when an event such as a game is communicated using a public line, the communication cost that the participants must bear becomes high, and if a large number of users access it at one time, the number of lines exceeding the maximum number will be used. However, there is a drawback that a person has to wait and cannot provide uniform service to a large number of users at a time.

On the other hand, when a mass communication system such as FM broadcasting or satellite broadcasting is used, a plurality of viewers can watch the same program at the same time, and the communication line can be compared to a case where a public line is used. There is an advantage that the communication cost is cheaper without using the usage fee. However, in the case of FM broadcasting and satellite broadcasting, since the types of data that can be transmitted are limited to audio and / or video, the viewer only has the right to select the program and cannot participate in the program by himself / herself. The broadcast contents could not be changed depending on the usage conditions of the broadcaster. Therefore, the viewer cannot actively enjoy the program by his / her own judgment, only by watching the broadcast.
Therefore, in the conventional broadcasting by mass communication, the content of the broadcasting service is fixed and the broadcasting is lacking in freshness. Further, when the receiving side uses data by communication while using an image processing device such as a home video game machine or a personal computer, an image by image broadcasting or image communication and an output image of the image processing device may be simultaneously or mutually associated. Since it cannot be viewed, a special image switching device is required, and control for switching and program production becomes complicated.

Therefore, the main object of the present invention is to provide a uniform service to a large number of users without requiring the users to pay a large amount of communication charges, and at the same time, allow viewers to actively participate in broadcast programs. It is to provide an information processing system by unidirectional mass communication that can realize a completely new broadcasting service. Another object of the present invention is to listen to a sound useful for assisting or assisting the progress of the game,
An object of the present invention is to provide an information processing system by unidirectional mass communication capable of playing a game that is different from the original program processing by control data.

[0006]

The present invention is an information processing system for supplying an audio signal and an image signal to an image display means to output an audio and an image, wherein a transmitting side includes an audio signal generating means, an audio data generating means and a control data. The generating means and the unidirectional mass communication means are provided, and the receiving side is provided with the receiving means, the data separating means, the voice data demodulating means, the control data decoding means, and the information processing means. A storage medium storing a desired program is associated with the information processing means.

[0007]

On the transmitting side, the voice data generating means generates voice data by pulse-code modulating the voice signals of various messages such as a game strategy, weather forecast, news and educational programs. The control data generating means generates control data relating to the meaning of the voice signal for each phrase or paragraph of the voice signal. The unidirectional mass communication means transmits the voice data and the control data in a data format having a predetermined synchronization pattern by adding the control data to the voice data. As a transmission method in this case, a method in which a large number of viewers can simultaneously receive in one direction such as FM broadcasting and satellite broadcasting is used.

On the other hand, on the receiving side, the receiving means receives the voice data and the control data transmitted from the unidirectional mass communication means. These transmission data are separated into voice data and control data by the data separating means. The audio data separated by the separating means is demodulated into the original audio signal by the audio data demodulating means and output as audio. The control data decoding means decodes the separated control data. The information processing means generates an image signal based on at least the program stored in the storage medium and supplies it to the image display means. Further, the information processing means changes the original processing based on the program stored in the storage medium based on the control data in association with the output of the demodulated audio signal as sound from the image display means. By performing the added processing, an image signal different from the original processing is generated. As a result, the image display means displays an image of characters, figures, etc. related to the audio signal.

[0009]

According to the present invention, it is possible to provide a uniform service to a large number of users without compelling the users to pay a large amount of communication charges, and to allow viewers to actively participate in broadcast programs. Broadcast service can be realized. Also,
According to a preferred embodiment in which the present invention is applied to a video game machine, a game is played or a broadcast station is being played while listening to a sound useful for assisting or assisting the progress of the game, such as a game capture method. It is possible to realize a completely new game such as playing a battle game with a player.

When receiving an audio broadcast by being connected to c and 53d, it is possible to display an image processed by the information processing unit 70 and output a commentary or auxiliary sound related to the display. Become.

A more specific application example will be described below. 5 shows a memory map of the ROM 81 (the game ROM is referred to as 81A in the following description) when the present invention is applied to a video game commentary broadcast, and FIG. 6 is a case where the present invention is applied to a video game commentary broadcast. 7 and 9 show flowcharts of the respective operations. Particularly, in this application example, the broadcasting station 10
When the player broadcasts a strategy (or commentary) for a game by voice, by transmitting control data such as a key code input by operating the controller 15b or the keyboard 15a in association with the voice, the viewer can A case where the operator himself operates the controller 71 to learn the optimum playing technique according to the model performance while listening to the capture method by voice is shown.

In FIG. 5, the ROM 81A has program storage areas 811 to 81 similar to general game software.
3 and a character data storage area 814. The storage area 811 is an area for storing a main program, and stores various main programs such as title screen display, initial setting, jump processing for each scene number, game over determination, and game over processing. The storage area 812 is an area for storing a game processing subroutine program for each scene number, for example, determining the coordinates of the enemy character, moving the enemy character, attacking the enemy character, hitting, hitting, etc. It stores various subroutine programs of. The storage area 813 is an area for storing an interrupt processing subroutine program, and stores, for example, a subroutine program such as interrupt sequence number processing and jump processing for each scene number. The minimum unit of the storage area 814 is 8 × 8
An area for storing 8-dot character data,
For example, font data of the main character, ally character, enemy character, background character, etc. is stored. Further, the ROM 81A includes a table storage area 815 for converting the key code of the transmitted instruction information and other program / data storage area 816 as storage areas specific to this embodiment.

In FIG. 6, when broadcasting to teach a strategy of a game and an operation procedure in that case, the viewer connects various devices on the receiving side as shown in FIG. 4 before broadcasting. Explanation of strategy method The cartridge 80 of the same game as the game to be broadcast is mounted on the information processing unit 70 and is on standby. Then, at the broadcast start time, the commentator or another model performer operates the controller 15b to perform the model operation in parallel with the commentary explaining the capture method by voice.

More specifically, when the broadcasting is started, the commentator etc. explain the introduction message of the program (for example, "Please attach the XX game cassette to the video game machine and turn on the power switch"). To do. Next, the commentator explains the outline of the scenario of the game, the operation method of the controller 15b, and the like, and then uses the controller 15b to perform an operation that serves as a model for the game. For example, when the screen (or scene) number for starting the game is input by operating the controller 15b, audio data corresponding to the audio of the explanation (for example, "what screen do you want to start?") Is audio RAM.
In addition to being temporarily stored in 14, the key code for screen selection is temporarily stored in the key code RAM 16. Then, the voice data and the key code data (control data) are temporarily stored in the transmission data memory 16 via the CPU 13 and sequentially transmitted. Next, the commentator gives a voice comment while playing (for example, how to attack which enemy character in which scene, how to avoid the enemy character's attack, and how to obtain advantageous items. Then, the voice data and control data such as a key code are sequentially transmitted in the same manner. In this way, the commentator sequentially explains the solution to the game during the broadcast of the program, and also teaches by playing the model play by operating the controller 71. Instead of transmitting the key code based on the operation of the controller 71, the coordinate data and the moving direction data of the main character may be transmitted based on the operation of the controller 71. Further, instead of the model operation, the key code of the keyboard 15a may be transmitted in order to transmit a message in characters to be transmitted to the player who is the viewer. When the end time of the program is reached, the end of the broadcast is announced by voice, and the end code is transmitted to end the broadcast. The announcer then broadcasts a voice message for another program.

While the above game-related explanation is broadcast, the following processing or operation is performed on the receiving side. That is, on the receiving side, when the power switch is turned on, the information processing unit 70 starts the operation of the main routine shown in FIG. 7 based on the program of the ROM 81A. First, step (abbreviated as "S" in the figure) 1
At 01, the game is initialized (for example, the score register and the life are reset). Step 102
At, a video signal for displaying the title screen is generated. In step 103, the controller 71
It is determined whether or not the start switch (not shown) has been operated. If the start switch is not operated, the demonstration screen is displayed in step 104, the process returns to step 102, and the operations of steps 102 to 104 are repeated until the start switch is pressed. On the other hand, when it is determined in step 103 that the start switch has been pressed, the process proceeds to step 105, and a subroutine for game processing is executed (see FIG. 9 described later). Then, in step 106, it is determined whether or not the game is over, and the processes of steps 105 and 106 are repeated until the game is over.

When a game commentary broadcast is received during execution of the main routine described above or a game processing subroutine described later, an interrupt signal is given to the information processing unit 70, and at the same time control data is received as buffer information in the buffer RAM 6
Temporarily stored in 2. In response to this interrupt signal, the information processing unit 70 executes the interrupt processing shown in FIG. That is, in step 111, the reception information stored in the buffer RAM 62 is read. Step 11
2, the received information read is the screen (or scene)
It is determined whether or not the number. When it is determined that the screen number is the screen number, the screen number is read in step 113, and then the process proceeds to step 121 shown in FIG. 9 described later as a jump destination (J1). On the other hand, if it is determined that it is not the screen number, it is determined in step 114 whether or not it is an end code. If it is determined that the received code is not the end code, after converting the received information into a key code in step 115,
Return to the process before the interrupt. On the contrary, when it is determined that the end code is received in step 114, step 1
After displaying the score in 16, the process returns to step 102 of FIG. 7 as the jump destination (J2).

Game processing subroutine (step 10
The details of 5) are performed according to the flow shown in FIG. 9 based on the program stored in the ROM 81A, for example. That is, in step 121, the received screen number data is read from the buffer RAM 62. Based on this scene number, in step 122, the setting of the scene (that is, the processing for displaying the image and outputting the sound of the scene) is performed. After that, the coordinates of the main character are calculated in step 123 in the same manner as the normal game processing. In step 124, calculations are performed to determine the coordinates of the enemy character. Step 125
At, calculations for the movement and attack of the enemy character are performed. In step 126, it is determined whether or not the received data includes the key code. When it is determined that the key code is present, in step 127,
The process of the model operation is performed based on the key operation state of the model player playing at the broadcasting station. After that, or after it is determined that the received data does not include the key code, it is determined in step 128 whether or not there is a key input by the player who is the viewer. When it is determined that a key input has been made, in step 129, a motion process of the hero character according to the key input (for example, a process of jumping, attacking, moving vertically and horizontally) is performed. After that, or after it is determined in step 128 that there is no key input, the effectiveness of the main character's attack is determined in step 130. Step 13 if not a valid attack
In 1, the effectiveness of the enemy's attack is judged. If the enemy's attack is not valid, the process returns to step 123. If the enemy's attack is effective, a process for extinguishing the main character is performed in step 132, and then the process returns to the original (main routine).

Furthermore, if it is determined in step 130 that the hero's attack is effective, in step 133 the enemy character disappearing process is performed. In the following step 134, it is judged whether or not all the enemies determined by the program have been defeated (that is, the enemies remain). If the enemies remain, the process returns to step 131. On the other hand, if there are no enemies left, the screen number is incremented in step 135, the process proceeds to the next screen, and the next screen can be played.

Therefore, in this embodiment, the game based on the operation of the model performer on the transmitting station side, even if the viewer player does not operate the controller 71 while listening to the voice message that advises the capture of the game. As a result, the viewer can visually check the model operation on the screen, and learn the strategy of the game along with the actual progress of the game. In addition, according to the explanation by the audio broadcast, the viewer performs the exemplary play by operating it himself,
It is also possible to practice the strategy.

It should be noted that this embodiment is not limited to the case of receiving the game-related broadcast, and the game can be independently enjoyed as in the case of the conventional game software. In that case, after determining in step 103 that the start switch has been pressed, the game process shown in FIG. 9 may be executed without executing the interrupt process shown in FIG.

By the way, in the embodiment shown in FIGS.
In addition to teaching how to conquer the game, one of the program participants at the broadcasting station and an unspecified number of viewers can also play the same game. In that case, the program participants play on the video game machine 15c in the broadcasting station 10, and the commentator gives an audio commentary. In addition, the game cartridge 80
The ROM 81A previously stores a program for a battle game with a computer and a program for converting a computer-side key code into a received key code. Then, when a key operation code when a program participant is playing a competitive game with a computer is added to an audio broadcast and transmitted, in the information processing unit (video game machine) 70 on the viewer side that receives the code. The received key code is regarded as the operation of the opponent on the computer side and the game proceeds. This has the advantage that an unspecified number of viewers can enjoy a battle game with a famous game player while staying at home.

Further, as another embodiment, the game program stored in the ROM 81 of the cartridge 80 is essential data essential for the game (for example, in the case of a baseball game, the game is performed according to the baseball rules). Program data and character data for realizing image display for that, and change data (for example, as individual / team data, if it is a batter, batting rate by opponent pitcher, misstep rate by each opponent team, stealing success rate, etc.) If it is a pitcher, the RAM 82 for storing data such as the defense rate and hit rate for each opponent batter may be backed up by a battery (not shown). In that case, in connection with another audio broadcast, data to be updated for each team is transmitted over a plurality of frames, the receiving side stores the received data in an updated manner, and the data stored in the RAM 82 is used as the original data. You may make it process so that various programs may be changed. In this way, even with the same game cartridge, a wide variety of games can be enjoyed just by receiving the update data and temporarily storing it.

Next, as another application of the present invention, an embodiment for transmitting a weather forecast or news will be described. 10 shows a memory map of the ROM 81 (the game ROM is referred to as 81B in the following description) when the present invention is applied to weather forecast and news broadcasting, and FIG. 11 shows the present invention for receiving the weather forecast and news programs. An explanation example and an operation example by voice when applied are shown, and FIGS. 12 to 15 show flowcharts of respective operations. In particular, in this application example, when the weather forecast or news is broadcast by voice from the broadcasting station 10, the keyboard 15a is operated in association with the voice to show a figure associated with the weather forecast (for example, a map or a type of weather is shown). Marks, precipitation probability, etc.), or by inputting news as text information and transmitting the key code, the weather forecast and news are notified to the viewer by voice and video.

In FIG. 10, the ROM 81B includes a program storage area 81a to 81f and a data storage area 81g.
81k and. The storage area 81a is an area for storing a main program, and stores various programs such as title screen display, initial setting, and waiting for key input. The storage area 81b is an area for storing a menu program, and stores, for example, a menu program such as menu screen display, key operation processing, and jump processing. The storage areas 81c to 81e are areas for storing subroutine programs, and programs corresponding to menus are stored therein. For example, the storage area 81c stores the program for controlling the display control of the Japan map and the weather mark when the menu is weather forecast. When the menu is a news program, the storage area 81d is
It stores a program for displaying a news screen frame and temporarily storing news character data. The storage area 81d stores programs for display control of other types of menus. The storage area 81f is an area for storing the program of the interrupt subroutine, and for example, processing for each control data (or each instruction information), rewriting of the background image (BG), rewriting of the register, writing to the RAM 82, etc. It stores various programs. Storage area 81g
Is an area for storing data for interpreting received information (also referred to as instruction information). The storage area 81h is an area for storing coordinate data for each city used when a map is displayed in a program such as a weather forecast. The storage area 81i is an area for storing character font data used when displaying characters in a news program. The storage area 81j is an area for storing background data. The storage area 81k is an area for storing other programs and data.

In FIG. 11, when viewing the weather forecast or news, the viewer attaches the weather forecast / news broadcasting cartridge 80B to the information processing unit 70 and waits before broadcasting. When the broadcast start time comes, the operator operates the keyboard 15a and operates the keys corresponding to the weather information and the contents of the news, while the announcer reads the weather forecast and the news aloud. For example, the title music of the music that has been broadcast until then is changed, and the theme music of the weather forecast is played. At this time, a designation code for changing the background image into a weather forecast image is input and transmitted in parallel with the change of the song title. After that, the announcer said, "We will send you the weather forecast for what day and time in what month."
To enter the weather forecast instruction code. This instruction code is transmitted together with the voice data. Next, the announcer reads the weather information of each place (for example, "Okinawa region has fine weather, memory 20 ° C, precipitation probability 0%"). At this time, the operator generates a code related to the weather by operating a key in which the region is "Okinawa", the weather type is "clear", and the precipitation probability is "0%". This key code is transmitted together with the voice data. After that, similarly, the weather forecast of each place is transmitted by voice and key code. When the broadcasting of the weather forecasts for all regions is finished, the announcer says "the weather forecast for what month, day, and hour will end.", And a code for specifying another background image is input.

Next, news is broadcast. In this case, the news of the day is broadcast by voice and the operator operates the keyboard 15a to input the character information summarizing the news contents, in the same procedure as the weather forecast broadcasting. The key code of this character information is transmitted sequentially.

Next, a detailed operation when the viewer views the program when the weather forecast or news is broadcast by voice and key input according to the procedure shown in FIG. 11 will be described.
In this case, the viewer attaches the weather forecast / news program cartridge 80 to the information processing unit 70 prior to the start of the broadcast time so that the information processing unit 70 can be installed.
Executes the programs shown in FIGS. First,
The main routine will be described with reference to FIG. In step 201, a weather forecast / news title screen is displayed. In step 202, the controller 7
It is determined whether or not the start switch included in 1 is pressed. If not, the process returns to step 201,
Wait until the start switch is pressed. And
When the start switch is pressed, the menu screen is displayed in step 203. In this menu screen, for example, in addition to characters such as "weather forecast" and "news" as a command for selecting a menu to be broadcast, "end selection" for designating the end of menu selection
, Etc. are displayed. In step 204, a key operation for selecting a menu is performed. At this time, if a menu other than the selection end is selected, it is determined in step 205 that the selection is not completed, and the subroutine processing for each menu selected in step 206 is performed. The processing of each menu is shown in FIG.
Alternatively, a detailed description will be given with reference to FIG.

When an interrupt signal is received during execution of the main routine described above or each of the menu processing subroutines described later, the interrupt processing shown in FIG. 13 is executed. That is, in step 211, the instruction information stored in the buffer RAM 62 is read. In step 212, the instruction information is decrypted based on the conversion table. In step 213, it is determined whether the title screen or the background screen is being displayed. If it is determined that it is not being displayed, it is determined in step 215 whether or not the operation based on the previous interrupt signal is being performed. If an interrupt is in progress,
After the respective information received in step 215 is stored in the RAM 82, the operation before the interruption is returned to. On the other hand, if it is determined in step 213 that the image is being displayed, it is determined in step 216 whether the received data is a background image rewriting command. If it is not a rewrite command, a jump destination for each instruction is obtained based on the program in step 217. In the following step 218, it is determined whether or not the jump destination is the first jump destination (J1), and J
If it is 1, the process proceeds to step 231 (FIG. 14), and if it is not J1, the process proceeds to step 251 (FIG. 15) of the third jump destination (J3).

If it is determined in step 216 that the instruction is a rewrite instruction, a jump destination for each instruction is obtained in step 219. Continued Step 220
After the display processing is performed in, the operation returns to the operation before the interrupt processing. If it is determined in step 214 that the interrupt operation is in progress, the jump destination for individual processing is determined in step 221. And step 2
In 22, the jump destination is the second jump destination (J2).
If it is J2, the process proceeds to step 237 shown in FIG. 14, and if it is not J2, the fourth jump destination (J
4) Step 257 (FIG. 15).

For example, when the weather forecast program is selected in step 204, the weather forecast subroutine shown in FIG. 14 is executed. First, in step 231, a map of Japan is displayed. In step 232, it is determined whether or not there is an interrupt signal (IRQ). If there is no interrupt signal, wait for the interrupt signal to come. On the other hand, when it is determined that the interrupt signal has arrived, the coordinates of the corresponding city are obtained based on the instruction information exchange table in step 233, and the weather mark, memory, and precipitation probability are obtained. In step 234, the map of the city (prefecture) or the area to which the city belongs (Kanto region, Kinki region, etc.) is displayed, and RA is received first.
Information relating to the weather forecast temporarily stored in M82, such as a mark indicating the type of weather, temperature, and probability of precipitation, is displayed in association with the map of the city. At this time, since the audio signal of the weather forecast is directly output from the separation / decoding circuit 52 (see FIG. 4) to the changeover switch 53, the audio broadcast of the weather forecast is displayed from the image display device 90 in parallel with the graphic / character display. Flowed. Then, in step 235, the value of the corresponding register is updated. In step 236, it is determined whether or not there is a key input. If there is no key input, the process returns to step 232, and if there is a key input, the process returns to the original main routine. As described above, the broadcasting of the weather forecast by voice and the image display by figures / characters are completed.

By the way, in this embodiment, only the control data for the display control of characters, figures, etc. is stored in the backup RAM 82 without watching the weather forecast broadcast at that time, and the backup is carried out after the program ends. You can also know the weather forecast based on the data. In that case,
After the weather forecast menu is selected in step 204, the weather forecast menu process is performed in step 206. That is, go to step 237,
A map of Japan is displayed. In the following step 238,
The coordinates of each city are obtained, and the weather forecast data is read. In step 239, a map of a city (prefecture) or an area to which the city belongs (Kanto region, Kinki region, etc.) is displayed, and information related to the weather forecast received previously and temporarily stored in the RAM 82, such as the weather information, is displayed. The mark indicating the type, temperature, probability of precipitation, etc. are displayed in association with the map of the city. In step 240, it is judged whether or not the display of all the received cities is completed, and if the display is not completed, step 238-
Repeat 240. When the display is completed, step 241
In (1), it waits until there is any key input, and when there is a key input, it returns to the main routine.

When the news program is selected in step 204, the news subroutine shown in FIG. 15 is executed based on the program stored in the storage area 81e. First, in step 251, a frame of the news screen is displayed. In step 252, it is determined whether or not there is an interrupt signal (IRQ). If there is no interrupt signal, wait for the interrupt signal to come. On the other hand, when it is determined that the interrupt signal arrives, a character font is obtained based on the character code of news in step 253. If it is determined in step 222 that the address is the fourth interrupt destination (43), step 2
After 52, the process proceeds to step 253. Continued Step 254
In, the news data is converted into character information and sequentially displayed in the news screen frame. At this time, since the audio signal of the news broadcast is directly output from the separation / decoding circuit 52 (see FIG. 4) to the changeover switch 53, the audio of the news is broadcast from the image display device 90 in parallel with the character display. In step 255, the character information is temporarily stored in the RAM 82. In step 256, it is determined whether or not there is a key input. If there is no key input, the process returns to step 252, and if there is a key input, the process returns to the original main routine. As described above, the broadcast of news by voice and the image display by text are completed.

By the way, in this embodiment, only the control data for controlling the display of characters and figures is stored in the backup RAM 82 without watching the news broadcast at that time, and the backup data is stored in the backup data after the program ends. The news can be viewed later as textual information as well. In that case, after the news menu is selected in step 204, the news screen frame is displayed in step 257. In step 258, the news data (code data) stored in the backup RAM 82 is read. Step 259
In, the news data is converted into character information and sequentially displayed in the news screen frame. At this time, news broadcasting by voice is not performed. In step 260, it is judged whether or not the display of all the received news data has been completed, and if the display is not completed, steps 258-2
Repeat 60. When the display is completed, the process waits until there is any key input in step 261, and returns to the original state if there is a key input.
