[A. Information Processing System 1]
Overview of an information processing system 1 according to the present embodiment will be described with reference to
Information processing system 1 includes a plurality of information processing apparatuses 100, 200-1, 200-2, . . . , and 300-1, 300-2, . . . which can exchange information with one another through radio communication. A plurality of information processing apparatuses shown in
Though
Processing in information processing apparatus 100 including each operation mode of a master, a client, and an audience will briefly be described below.
Information processing system 1 according to the present embodiment is applied, for example, to applications where a plurality of users participate in a common game field and enjoy a game. Information processing apparatus 100 functioning as the master performs processing necessary for representation on information processing apparatus 100 itself and a plurality of information processing apparatuses including the clients and the audiences. The master generates an application image to be shown to the client and the audience included in information processing system 1 and directly transmits the application image to each information processing apparatus.
The “application image” herein means moving images and still images including a result of execution of application processing and may be any of rendering using a virtual camera, computer graphics, and actual video images. Though expressions along with progress of game processing will be described by way of example of an “application image” in the description below, any type of application is acceptable.
The client and the audience receive and show an application image transmitted from the master. Though the client can participate in an application executed by the master, the audience cannot participate in the application executed by the master. The client accepts an operation by a user onto the client apparatus and directly transmits operation information to the master. The master performs application processing in accordance with operation information transmitted from one client or a plurality of clients. The audience shows an image of an application (an application image) which proceeds as the master user and the client users participate. Even when the audience user performs some operation, operation information accepted by audience information processing apparatus 300 is not transmitted to the master. As will be described later, in response to a prescribed operation by the audience user, switching to an operation mode in which the user can participate in the application executed by the master, that is, the client, can also be made.
Typical processing in information processing system 1 includes acceptance of an operation from a master user and a client user ((1) operation). Each client transmits operation information indicating contents of the accepted operation to the master ((2) transmission). The master performs application processing in accordance with operation information indicating contents of the operation accepted by the master apparatus and operation information received from each client ((3) application processing). Then, the master transmits an application image including a result of execution of the application processing to the client and the audience ((4) application image). In information processing system 1, processing in (1) and (4) shown in
In information processing system 1, switching between the master and the client, between the client and the audience, and between the master and the audience may be made. For example, an information processing apparatus operating as the client may operate as the master in response to an explicit or implicit instruction.

Processing performed in each of information processing apparatuses (master, client, and audience) included in information processing system 1 according to the present embodiment will now be described with reference to
In information processing apparatus 100 functioning as the master, a game program 140 for implementing processing as will be described later is executed. Game program 140 is installed through any storage medium (for example, a semiconductor storage device or a communication line). Information processing apparatus 200 functioning as the client and information processing apparatus 300 functioning as the audience execute respective interface programs 240 and 340 simpler in processing contents than game program 140 (that is, smaller in amount of contained instruction codes).
A program itself may be the same between interface program 240 and interface program 340 and executed contents may be switched in accordance with an operation mode. Furthermore, a program including all of game program 140, interface program 240, and interface program 340 may be installed in each information processing apparatus and a corresponding program may selectively be executed in accordance with an operation mode designated by a user.
Interface programs 240 and 340 are preferably configured to be executable with any of a plurality of applications (game programs). For example, interface programs 240 and 340 may be mounted as a part of a basic application such as a launcher or an OS installed in advance in an information processing apparatus. Alternatively, the interface program may be executed on another game program executed in information processing apparatus 200. In this case, interface program 240 and interface program 340 are mounted as a type of a program module and called at any timing by another program.
A module included in each information processing apparatus shown in
Referring to
Radio communication module 150 mediates data exchange through a radio signal between remote input module 154 and remote output module 174, and information processing apparatus 200 functioning as the client and information processing apparatus 300 functioning as the audience. Radio communication module 150 corresponds to a layer performing processing in a higher-order layer in accordance with a result of exchange of the radio signal by radio communication unit 120 (
Local input module 152 outputs operation information M generated in response to an operation by a user which has been accepted by operation portion 116 (
Application execution module 160 performs application processing based on operation information accepted by operation portion 116 of information processing apparatus 100 and operation information from information processing apparatus 200 functioning as the client. More specifically, application execution module 160 implements simultaneous play between the master user and the client user. Application execution module 160 holds a game space 162 and character data 164, and performs application processing based on operation information M from the master and operation information C1, C2, . . . from the client. Application execution module 160 proceeds with game processing based on operation information from users who participate in a game.
Local output module 172 and remote output module 174 output a result of execution of application processing by application execution module 160. Local output module 172 generates an application image including a result of execution of application processing and has display 114 of information processing apparatus 100 show the application image. Remote output module 174 transmits the application image to information processing apparatus 200 functioning as the client through radio communication unit 120 of information processing apparatus 100.
Local output module 172 outputs the application image generated through execution of application processing to display 114 (
Information on an application image and voice and sound may be compressed with a prescribed compression method and transmitted to information processing apparatus 200 functioning as the client. Different compression methods suitable for an application image and voice and sound, respectively, may be adopted, or both of the application image and the voice and sound may be compressed with the same compression method.
Depending on contents of application processing, audio data may not be output and only an application image may be output. Alternatively, to the contrary, an application image may not be output and only audio data may be output.
In information processing apparatus 200 functioning as the client, interface program 240 which is a program simpler than game program 140 executed in information processing apparatus 100 functioning as the master is executed. In information processing system 1 according to the present embodiment, main operation necessary for application processing is performed in information processing apparatus 100 functioning as the master and only input and output processing involved with a user interface is basically performed in information processing apparatus 200 functioning as the client.
More specifically, information processing apparatus 200 includes a radio communication module 250, an input module 252, and an output module 254. Radio communication module 250 mediates exchange of data through a radio signal between input module 252 and output module 254, and information processing apparatus 100 functioning as the master. Radio communication module 250 corresponds to a layer performing processing in a higher-order layer in accordance with a result of exchange of a radio signal by radio communication unit 120 (
Input module 252 transmits through radio communication module 250, operation information generated in response to an operation by a user which has been accepted by operation portion 116 (
Output module 254 receives an application image and audio data through radio communication module 250 from information processing apparatus 100 functioning as the master, and outputs the application image to display 114 (
Information processing apparatus 300 functioning as the audience executes interface program 340 simpler than any of game program 140 executed by information processing apparatus 100 functioning as the master and interface program 240 executed by information processing apparatus 200 functioning as the client. Information processing apparatus 300 functioning as the audience provides only a function to check a state of play by other users.
More specifically, information processing apparatus 300 includes a radio communication module 350 and an output module 352. Radio communication module 350 is similar to radio communication module 250 of information processing apparatus 200 functioning as the client and output module 352 is similar to output module 254 of information processing apparatus 200 functioning as the client.
A function corresponding to input module 252 is not activated in information processing apparatus 300, and operation information in response to an operation by a user onto operation portion 116 of information processing apparatus 300 is not transmitted to information processing apparatus 100 functioning as the master. Information processing apparatus 300 has a function to inactivate transmission of operation information accepted by operation portion 116 of information processing apparatus 300 to information processing apparatus 100 but to have display 114 of information processing apparatus 300 show an application image from information processing apparatus 100.
A program necessary for configuring information processing system 1 according to the present embodiment may be stored in advance in a corresponding information processing apparatus. Information processing apparatus 100 functioning as the master may have a storage unit (for example, auxiliary storage unit 106 or main storage unit 104 shown in
[D. Communication Scheme Between Master, and Client and Audience]
In information processing system 1 according to the present embodiment, each of information processing apparatuses 200 functioning as the clients corresponds to a type of an operation terminal including functions corresponding to display 114, operation portion 116, and audio output unit 118, when viewed from information processing apparatus 100 functioning as the master. Each of information processing apparatuses 300 functioning as the audiences corresponds to a type of a display terminal including functions corresponding to display 114 and audio output unit 118 when viewed from information processing apparatus 100 functioning as the master.
The master should identify operation information transmitted from each client and perform application processing. In input processing in the master, when the master receives some kind of operation information from any client, the master should specify contents of received operation information and a sender of the received operation information. In contrast, in typical output processing in the master, the master transmits the same application image and audio data to a plurality of information processing apparatuses.
In information processing system 1 according to the present embodiment, in one form, a communication scheme for transmitting operation information from information processing apparatus 200 functioning as the client and a communication scheme for transmitting an application image and audio data from information processing apparatus 100 functioning as the master are adapted to respective purposes.
A scheme for communication among information processing apparatuses in information processing system 1 according to the present embodiment will be described with reference to
Radio communication unit 120 of information processing apparatus 200 functioning as the client transmits operation information to information processing apparatus 100 functioning as the master in unicast. By using transmission data in such a unicast format, information processing apparatus 100 functioning as the master specifies contents of operation information included in received data and a sender of the operation information and performs application processing (typically, game processing) 610.
Information processing apparatus 100 functioning as the master transmits an application image and audio data including a result of execution of application processing to the client and/or the audience. It is also assumed that the master does not know in advance which information processing apparatus functions as the audience. Such an application that the master invites any information processing apparatus within coverage of radio communication to participate as audience is also assumed.
Therefore, in information processing system 1 according to the present embodiment, radio communication unit 120 of information processing apparatus 100 functioning as the master transmits a generated application image and audio data to another information processing apparatus in either broadcast or multicast (reference 620). In the broadcast format, received data can be used in all information processing apparatuses which can receive a radio signal sent from the master. In the multicast format, the master designates a plurality of destinations and then transmits a generated application image and audio data. The same data can be used among a plurality of information processing apparatuses designated as destinations by the master.
In the unicast format, the number of information processing apparatuses which can simultaneously exchange data is limited to a certain upper limit. In the broadcast format and the multicast format, however, the number of information processing apparatuses which can receive and use data is larger than in the case of the unicast format, and the number of connections is not limited in some cases.
By thus optimizing a communication scheme between the master, and the client and the audience, progress of application processing (game processing) based on operation information transmitted from the client can further be stabilized, the number of information processing apparatuses which can participate as the audience can be increased, and application to such applications as inviting more users to participate can also be facilitated.
[E. Transition of Operation Mode]
Processing for transition among operation modes of the master, the client, and the audience will now be described with reference to
For example, when a user of an information processing apparatus in which game program 140 (
When a user of an information processing apparatus which has received a notification message from information processing apparatus 100 functioning as the master indicates participation in the game ((2) instruction to participate in game), the information processing apparatus functions as the client. When an information processing apparatus functions as the client, typically, notification reception representation processing 280, image and audio output processing 282, and operation information transmission processing 284 are performed. Notification reception representation processing 280 is processing for showing a notification message from information processing apparatus 100 functioning as the master. Image and audio output processing 282 is processing for showing an application image from information processing apparatus 100 functioning as the master and outputting audio data. Operation information transmission processing 284 is processing for transmitting operation information generated in response to an operation by a user which has been accepted by operation portion 116 (
Alternatively, when a user of an information processing apparatus which has received a notification message from information processing apparatus 100 functioning as the master indicates watch of a game ((3) instruction to participate as audience), the information processing apparatus functions as the audience. When an information processing apparatus functions as the audience, typically, notification reception representation processing 380 and image and audio output processing 382 are performed. Notification reception representation processing 380 and image and audio output processing 382 are the same as notification reception representation processing 280 and image and audio output processing 282, respectively. When the user of information processing apparatus 300 functioning as the audience indicates participation in the game ((4) instruction to participate in game), switching between operation modes from the audience to the client is made in the information processing apparatus.
When the master user indicates end of the game ((5) instruction to quit game) after application processing (game processing) is performed between the master and the client, the information processing apparatus quits the function as the master. When game program 140 (
[F. User Interface Screen]
One example of a user interface screen provided on an information processing apparatus will now be described with reference to
When a user executes game program 140 (
Choice item 402 is provided with a message “1. one player.” When this choice item is selected, a user can play a game against the computer.
Choice item 403 is provided with a message “2. match-up play.” When this choice item is selected, the information processing apparatus functions as the master. “(1) Instruction to start game” shown in
Choice item 404 is provided with a message “3. search for game being played.” When this choice item is selected, the information processing apparatus functions as the client or the audience. “(2) Instruction to participate in game” or “(3) instruction to participate as audience” shown in
When choice item 403 is selected in menu screen 400 shown in
After a prescribed period has elapsed since transmission of the notification message to other information processing apparatuses or when the number of participating users has reached a predetermined number, a confirmation screen 420 shown in
When choice item 404 is selected in menu screen 400 shown in
In status screen 440, detailed information on a game inviting participants (for example, a title of the game or description of game contents) may be included. A name of a user who has currently participated in the game may also be shown.
When any game is selected in status screen 440 shown in
When a user operates a cursor 453 to select choice item 451, the information processing apparatus functions as the client. “(2) Instruction to participate in game” shown in
When a user operates cursor 453 to select choice item 452, the information processing apparatus functions as the audience. “(3) Instruction to participate as audience” shown in
When any choice item is selected in selection screen 450 shown in
In contrast, in information processing apparatus 300 (audience) in which the user watches the game, an operation by the user is inactivated. In response to a prescribed operation by the user, a selection screen 470 shown in
In an information processing apparatus which has received the notification message from information processing apparatus 100 functioning as the master, a notification screen 480 as shown in
When a user operates a cursor 484 to select choice item 481, the information processing apparatus functions as the client. “(2) Instruction to participate in game” shown in
In contrast, when a user operates cursor 484 to select choice item 483, the information processing apparatus does not become any of the client and the audience.
[G. Notification Function]
A notification function to transmit a notification message from the master will now be described. The notification message is transmitted from information processing apparatus 100 functioning as the master and serves to have information processing apparatus 200 start transmission of operation information to information processing apparatus 100. It is a message inviting a user who operates an information processing apparatus other than information processing apparatus 100 functioning as the master to establish connection to the master. The notification message is typically transmitted from information processing apparatus 100 at any timing as a beacon.
(g1: Reception Side of Notification Message)
When an information processing apparatus other than information processing apparatus 100 functioning as the master receives a notification message, it performs processing for having a user recognize reception of the notification message. For example, any method such as vibrating a main body or a part thereof, causing an indicator to blink or turning on the indicator, or generating prescribed voice and sound from the speaker, can be adopted. The user can know that there is a game which can be played or watched in the surroundings through an action of the information processing apparatus associated with reception of the notification message. Typically, a user who carries an information processing apparatus notices some kind of a notification action, has the information processing apparatus recover from a low power consumption state (or a sleep state), and can enjoy playing or watching the game.
(g2: Given Message)
One example of a data structure of a beacon used in information processing system 1 according to the present embodiment will be described with reference to
Sender address 502 includes a media access control (MAC) address or an Internet protocol (IP) address of information processing apparatus 100 functioning as the master which is the sender of beacon 500. BSSID 504 includes an identifier on a radio network of information processing apparatus 100 functioning as the master which is the sender of beacon 500. Game ID 506 includes identification information for specifying a game inviting participants. The number of connections 508 indicates the number of current participants in a game inviting participants. The maximum number of connections 510 indicates the maximum number of participants allowed to participate in a game inviting participants. List of established connections 512 includes information for specifying an information processing apparatus connected to information processing apparatus 100 functioning as the master. Watch permission flag 514 includes a flag as to whether or not to permit participation in a game inviting participation as the audience.
By adopting such a beacon, processing for transmitting a notification message for inviting participation by users can readily be performed.
As described above, an information processing apparatus which has received a notification message has the main body or a part thereof vibrate, so that a user who carries the information processing apparatus is notified of reception of the notification message. The notification message is a trigger for generating vibration in a destination information processing apparatus. Thus, remote output module 174 of information processing apparatus 100 transmits, in addition to an application image, vibration data generated through application processing to information processing apparatus 200 functioning as the client.
The notification message may include any information. For example, though beacon 500 shown in
The notification message may include not only contents of the game inviting participants but also any information. For example, when a new application (game) is released, an advertisement message may be included together with an image showing contents thereof. The notification message may include advertisement information. Alternatively, while a game proceeds, a message to the effect that watch is invited because the game is in progress may be included.
Since information processing apparatus 100 functioning as the master can thus transmit a notification message at any timing, it can distribute messages in various applications to other information processing apparatuses which can communicate with information processing apparatus 100 through a radio signal. Timing to transmit a notification message may randomly be determined, or a notification message may be transmitted with approach by a new information processing apparatus to information processing apparatus 100 functioning as the master being regarded as an event.
As will be described later, a beacon can be transmitted over wireless LAN or Bluetooth™ Low Energy (BLE). Such a beacon can preferably be received regardless of a situation of an information processing apparatus. Therefore, the information processing apparatus according to the present embodiment is configured to be able to receive a notification message transmitted from information processing apparatus 100 functioning as the master even when a specific application is not being executed.
Which communication scheme is to be employed is determined depending on hardware of an information processing apparatus functioning as the client or the audience. A scheme for communication of a notification message transmitted from information processing apparatus 100 functioning as the master may be different depending on a type of an information processing apparatus functioning as the client or the audience.
(g3: Filtering of Notification Message)
A notification message may be transmitted at any timing from the master. A user who receives such a notification message may desire reception only of a notification message from a specific sender. In this case, an information processing apparatus functioning as the client or the audience is configured to activate only a notification message satisfying a predetermined condition among notification messages transmitted from information processing apparatus 100 functioning as the master.
Specifically, a function to filter a notification message as will be described below is preferably mounted. For such a filtering function, a method of including specific identification information in a transmitted notification message and/or a method of identifying a notification message to be received on a reception side are assumed.
For example, in the method of including specific identification information in a transmitted notification message, a keyword or a test word necessary for opening a notification message may be set in advance and only a user who knows the keyword or the test word can open the notification message. Alternatively, a notification message may be transmitted as being encrypted with a certain encryption key and only a user who has a corresponding decryption key in advance can decrypt the notification message.
By thus adding information shared among specific users to a notification message, such a situation that contents of a notification message are leaked to a third party can be prevented.
In the method of identifying a notification message to be received on a reception side, contents of the notification message may be shown only when the identification information included in the notification message match with identification information of a user registered in advance (for example, a user in friend relation or a user registered in an address book).
Alternatively, a sender from which a user on a reception side can receive a message may explicitly be set, or a condition for reception in connection with contents or an attribute included in a notification message may be set in advance.
By thus making filtering setting on the reception side, reception of an unnecessary notification message not desired by a user on the reception side can be suppressed.
(g4: Wireless LAN)
When wireless LAN under 802.11 standards is employed for radio communication unit 120 (
The action frame can be received as an event even when an information processing apparatus is in a low power consumption state (for example, in a sleep state or a stand-by state) so long as a physical layer and a data link layer of radio communication unit 120 which provides a wireless LAN interface are active. Even when an information processing apparatus is executing some kind of application, it can also receive an action frame in the background.
A frequency in a 2.4 GHz band and a 5 GHz band is currently allocated to wireless LAN under 802.11 standards, and the information processing apparatus according to the present embodiment can use both of these two frequency bands. There is a case that the 2.4 GHz band and the 5 GHz band cannot simultaneously be used because of hardware restrictions, and in such a case, a frequency band to be used is preferably switched as appropriate.
One example of processing for switching between frequency bands used for wireless LAN in the information processing apparatus according to the present embodiment will be described with reference to
Information processing apparatus 100 functioning as the master is configured to transmit an application image and a notification message in different frequency bands. In such a case, an information processing apparatus functioning as the client or the audience receives an application image and receives a notification message by sequentially switching between the frequency bands in which radio communication unit 120 effectively communicates.
More specifically, the information processing apparatuses functioning as the client and the audience mainly communicate in the 5 GHz band for reception of an application image, however, they receive a frame transmitted in the 2.4 GHz band every prescribed period or every prescribed event in order to check whether or not there is an action frame.
By communicating over wireless LAN while switching between such frequency bands is made, an action frame can also be searched for and received while an application image necessary for representation on a display is received.
Alternatively, two types of information can selectively be received through different channels included in the same frequency band. For example, an application image may be received through a communication channel 1 in a certain frequency band and an action frame may be received through a communication channel 2 in that frequency band. In this case, channels included in the same frequency band are alternately activated, so that an action frame can also be searched for and received while an application image necessary for representation on a display is received.
Since a dedicated instruction can be embedded in an action frame adapted to wireless LAN as described above, information processing apparatus 100 configuring information processing system 1 can perform more suitable processing.
(g5: Bluetooth™ Low Energy (BLE))
When Bluetooth™ is employed for the radio communication unit (
By employing BLE as described above, a beacon can be exchanged among a plurality of types of information processing apparatuses which are different in hardware.
When a certain information processing apparatus functions as the client or the audience in response to transmission and reception of a notification message over BLE, it receives an application image and audio data transmitted over wireless LAN. Though a scheme for communication of a notification message may be different depending on a type of an information processing apparatus, once connection is established, information processing apparatus 100 functioning as the master transmits an application image and audio data under the same communication scheme after the notification message is transmitted.
[H. Processing Procedure]
A procedure of processing in each information processing apparatus configuring information processing system 1 according to the present embodiment will now be described.
(h1: Information Processing Apparatus Functioning as Master)

Then, information processing apparatus 100 transmits an application image and audio data including a result of execution of game processing to the client and the audience (step S122).
Thereafter, information processing apparatus 100 determines whether or not end of game processing has been indicated (step S124). When end of game processing has not been indicated (NO in step S124), processing in step S118 and later is repeated. When end of game processing has been indicated (YES in step S124), the game processing ends.
When choice item 403 “3. search for game being played” is selected on menu screen 400 (“search for game in which you can participate” in step S102), processing shown in
(h2: Information Processing Apparatus Functioning as Client/Audience)
Referring to
When information processing apparatuses 200 and 300 have received a notification message (YES in step S200), information processing apparatuses 200 and 300 show status screen 440 shown in
When choice item 451 “1. participate” is selected on selection screen 450 (“participate” in step S206), information processing apparatus 200 directly transmits a message indicating participation in the game as the client to information processing apparatus 100 functioning as the master (step S208). Then, when the game is started, information processing apparatus 200 obtains operation information in accordance with an operation by the user which has been accepted by operation portion 116 and directly transmits the obtained operation information to information processing apparatus 100 functioning as the master (step S210). Information processing apparatus 200 outputs an application image and audio data received from information processing apparatus 100 functioning as the master (step S212). Thereafter, information processing apparatus 200 determines whether or not end of game processing has been indicated (step S214). When end of game processing has not been indicated (NO in step S214), processing in step S208 and later is repeated. When end of game processing has been indicated (YES in step S214), game processing ends.
When choice item 452 “2. watch” is selected on selection screen 450 (“watch” in step S202), information processing apparatus 300 outputs an application image and audio data received from information processing apparatus 100 functioning as the master after the game is started (step S222). Information processing apparatus 300 shows on display 114, selection screen 470 shown in
[I. Approval of Participation by User]
In information processing system 1 according to the present embodiment, information processing apparatus 100 functioning as the master invites participation in the game and users who desire participation in response thereto will participate in the game. Though the feature to invite many users to participate in the game is preferred from a point of view of a lower barrier to users who can participate in the game, it does not fulfill such needs as desire to enjoy a game only among specific members. In such a case, the master user may be able to determine whether or not to approve a user who desires participation.
Thus, information processing apparatus 100 functioning as the master determines whether or not to permit transmission of operation information to information processing apparatus 100 by a certain information processing apparatus in response to an operation by a user, that is, connection as the client.
By adopting such processing, such needs as desire to enjoy a game only among specific members can be fulfilled.
[J. Transmission of Application Image and Audio Data]
In information processing system 1 according to the present embodiment, an application image and audio data are transmitted from information processing apparatus 100 functioning as the master to one information processing apparatus or a plurality of information processing apparatuses. A form as below may be adopted for processing for transmitting an application image and audio data.
(j1: Batch Transmission of Multiple Screens)
When a plurality of users participate in a common game, depending on a type of a game, such a form as providing the same application image to all users may be adopted, or such a form as providing application images different for each user (information processing apparatus) may be adopted. Exemplary processing for providing application images different for each user (information processing apparatus) will be described below.
Application images different for each user (information processing apparatus) may include images generated for respective points of view of respective users arranged in a game space. Alternatively, even though a point of view is the same, representation in line with progress of a game such as a name of a character operated by each user or a power gauge is different for each user. A method of providing an application image specific for each user will be described.
A method of generating and transmitting an application image for each information processing apparatus in information processing system 1 according to the present embodiment will be described with reference to
As shown in
Information processing apparatuses 200-1 to 200-4 are provided in advance with respective pieces of identification information ID01 to ID04 each indicating which partial image included in application image 530 is to be shown. Each of information processing apparatuses 200-1 to 200-4 shows on the display, an image in a specific region (a partial image) of received application image 530, based on identification information provided in advance.
Thus, information processing apparatus 100 functioning as the master transmits an application image which is integration of application images generated for respective information processing apparatuses 200. Information processing apparatus 200 shows on display 114, an image corresponding to information processing apparatus 200 itself, of the integrated application image.
As shown in
(j2: Time Division Transmission)
Instead of a form of transmission of an application image including a plurality of partial images as described above, an application image may be transmitted for each information processing apparatus 200 functioning as the client.
A method of generating and transmitting an application image for each information processing apparatus in information processing system 1 according to the present embodiment will be described with reference to
Information processing apparatuses 200-1 to 200-4 are provided in advance with respective pieces of identification information ID01 to ID04 each indicating a position in one frame, of an application image to be extracted. Each of information processing apparatuses 200-1 to 200-4 extracts a specific application image in one received frame based on identification information provided in advance and shows the application image on the display.
By thus transmitting a plurality of application images in the prescribed order, each of the plurality of information processing apparatuses 200-1 to 200-4 can show an application image for each user. Versatility and zest of a game can thus be enhanced.
(j3: Optimization of Resolution)
Though an example in which information processing apparatuses substantially the same in hardware configuration function as clients has been described above, information processing apparatuses functioning as the clients may also be different in hardware specifications from one another. In this case, a resolution of an application image to be transmitted is preferably optimized.
A method of optimizing a resolution of an application image for each information processing apparatus in information processing system 1 according to the present embodiment will be described with reference to
For example, information processing apparatus 200-1 has a representation resolution D1 (W1×H1), information processing apparatus 200-2 has a representation resolution D2 (W2×H2), and information processing apparatus 200-3 has a representation resolution D3 (W3×H3). Information processing apparatus 200-3 is lowest in representation resolution D3 (lowest in specifications).
In such a case, information processing apparatus 100 functioning as the master may generate an application image so as to adapt to the lowest representation resolution. In this example, an application image having representation resolution D3 (W3×H3) is generated and transmitted to each client. Information processing apparatus 100 functioning as the master may convert an application image to a prescribed resolution and transmit the converted application image to information processing apparatus 200. Thus, regardless of a type of information processing apparatuses 200-1 to 200-3, an application image may be transmitted with a resolution being uniformly lowered. In contrast, application images having a plurality of types of resolutions may individually be generated in accordance with representation resolutions of information processing apparatuses 200-1 to 200-3.
As described above, since information processing apparatus 200 functioning as the client transmits operation information to information processing apparatus 100, it may transmit information on a maximal size of an image which can be shown on a mounted display, that is, a representation resolution, at the timing of transmission of the operation information.
Alternatively, information processing apparatus 200 functioning as the client may negotiate a representation resolution in a procedure for connection to information processing apparatus 100 functioning as the master.
By adopting such a configuration, even when a plurality of clients different in hardware specifications from one another participate in a game, a plurality of users can enjoy the game without awareness of differences in specifications.
To the contrary, information processing apparatus 100 functioning as the master may generate an application image in accordance with the highest representation resolution among a plurality of clients and transmit the application image. Each client reduces the received application image to a size of an image which can be shown and then shows the application image on the display.
By adopting such a configuration, a client higher in hardware specifications can enjoy video images in accordance with its specifications and even a client lower in hardware specifications can participate in a game.
(j4: Restriction of Destination of Application Image)
In information processing system 1 according to the present embodiment, information processing apparatus 100 functioning as the master transmits an application image in either broadcast or multicast. Therefore, basically, an apparatus capable of radio communication with information processing apparatus 100 functioning as the master can show an application image. Such a feature of ability to show an application image on any apparatus is preferred from a point of view of a lower barrier to users who can participate in a game, however, it does not fulfill such needs as desire to enjoy a game only among specific members. In such a case, such a scheme that only a specific information processing apparatus can show an application image may be adopted.
A method of restricting a destination of an application image in information processing system 1 according to the present embodiment will be described with reference to
In the configuration shown in
Any method can be adopted as the method of distributing a decryption key in advance. For example, a decryption key may be distributed over a community network among users such as a social network (SNS). In this case, a set of an encryption key and a decryption key under a public encryption scheme may be made use of.
Alternatively, a decryption key may be obtained by accessing a site from which various programs including an interface program described above are downloaded on a chargeable or free-of-charge basis. Alternatively, an encryption key is distributed through a radio signal to game distributors or convenience stores and the encryption key may be obtained at such a location.
By restricting an information processing apparatus which can show an application image by using such an encryption key, only users in a closed user community can share and enjoy a game. By prohibiting obtainment of an encryption key at locations other than a specific location, a kind of rareness can be produced.
[K. Use of General-Purpose Device as Client/Audience]
In information processing system 1 according to the present embodiment, so long as game program 140 (
A smart device such as a smartphone or a tablet or a general-purpose device such as a personal computer can be employed as the client or the audience. In this case, an interface program for functioning as the client or the audience should be installed in the general-purpose device. Such an interface program should only be distributed and installed with a known method.
For example, an interface program may be distributed as being stored in such a storage medium as an optical disc, or stored in a distribution server and downloaded by accessing the distribution server.
A method of installing an interface program in a general-purpose device in information processing system 1 according to the present embodiment will be described with reference to
When a user of information processing apparatus 200 indicates access to a URL included in the received notification message, information processing apparatus 200 accesses the designated download site and downloads and installs the designated interface program.
Through a series of such processes, even a user of a general-purpose device can readily participate in information processing system 1 in the present embodiment and a plurality of users can enjoy a game.
Alternatively, information processing apparatus 100 may serve as an NFC tag with a card emulation function and information processing apparatus 200 as a reader-writer may read information (URL) on a tag from information processing apparatus 100.
A known method such as infrared communication, wireless LAN, and Bluetooth™ can be adopted for transmission of an interface program from information processing apparatus 100 to information processing apparatus 200, without being limited to NFC.
Through such a procedure, a user of information processing apparatus 200 can participate in a game provided by information processing apparatus 100 without much awareness of presence of an interface program.
[L. Use of General-Purpose Device as Master]
Though an example in which a general-purpose device is made use of as the client or the audience has been exemplified in the description above, a general-purpose device may be employed as the master. Though game program 140 executed in a general-purpose device should be prepared in this case, any type of information processing apparatus may be employed as an information processing apparatus to serve as the client or the audience.
[M. Modification]
A modification as below may be adopted in the embodiment described above.
Information processing apparatus 100 functioning as the master may transmit a common application image to a plurality of information processing apparatuses 200 functioning as the clients (and information processing apparatus 300 functioning as the audience). In contrast, information processing apparatus 100 functioning as the master may transmit individual application images to a plurality of information processing apparatuses 200 functioning as the clients (and information processing apparatus 300 functioning as the audience), respectively.
Furthermore, the two transmission methods described above may be combined with each other. In this case, information processing apparatus 200 functioning as the client may show the received common application image and the individual application image as being combined with each other. In a more specific application example, an individual application image may be an image of a common game field and an individual application image may be an image of a name of a character associated with a user who operates each of a plurality of information processing apparatuses 200, a power gauge, and a group of items which are being held.
A common application image and individual application images may simultaneously be transmitted in broadcast (or multicast). Alternatively, a common application image may be transmitted in broadcast (or multicast), whereas an individual application images may individually be transmitted in unicast to target information processing apparatuses 200.
By adopting combination of such a common application image and an individual application image, in spite of restriction of throughput, a screen for each of the plurality of users can be provided while redundant data transmission is suppressed.
[N. Advantages]
In information processing system 1 according to the present embodiment, an information processing apparatus functioning as the master should only be able to use a game program and other information processing apparatuses should only be able to use a simple program for exchange with the information processing apparatus functioning as the master. In the present embodiment, restriction associated with hardware necessary for a plurality of users to enjoy the same game can be relaxed.
While certain example systems, methods, devices, and apparatuses have been described herein, it is to be understood that the appended claims are not to be limited to the systems, methods, devices, and apparatuses disclosed, but on the contrary, are intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
