MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of a technology to be disclosed herewith will be described with reference to the drawings.

FIG. 1 s a diagram illustrating a configuration example of a cooperative processing system according to an embodiment of the present technology. In this example, devices 21 to 25 are connected to a LAN (Local Area Network) 10 to configure a cooperative processing system. Note that the LAN 10 is connected to a WAN (Wide Area Network) 11 through a router (not illustrated) and the like.

The device 21 is configured as a television receiver, for example. FIG. 2 is a block diagram illustrating a configuration example of the device 21 of FIG. 1.

A CPU 71 is a main controller that controls an operation of the whole device 21, and controls a tuner 79, a demodulation unit 80, a decoder 81, an HDD 78, and the like based on an input signal supplied from an input unit 76 to execute recording or reproducing of a TV program.

A RAM 73 is a writable volatile memory used for loading an execution program of the CPU 71, and for writing work data of the execution program. A ROM 72 is a read-only memory that stores a self-diagnosis/initialization program executed at power on of the device 21, a control code for hardware operation, and the like.

The input unit 76 is configured from, for example, a remote commander (remote controller), a button, a switch, a keyboard, and the like, and outputs an input signal corresponding to an operation to the CPU 71 through an input/output interface 75 and a bus 74.

A communication unit 77 communicates with another information processing apparatus as necessary, for example, through a network.

The HDD 78 is a randomly accessible storage device capable of accumulating a program, data, and the like in a file type having a predetermined format. The HDD 78 is connected to the bus 74 through the input/output interface 75, receives data for data broadcasting such as a broadcast program and EPG data from the decoder 81 and the communication unit 77, records the information, and outputs the recorded data, as necessary.

A broadcast wave received by an antenna (not illustrated) is supplied to the tuner 79. The broadcast wave is based on a predetermined format, and may include the EPG data. Differences of a satellite broadcasting wave, a ground wave, a wired or wireless wave are not especially considered for the broadcast wave.

The tuner 79 performs tuning of the broadcast wave of a predetermined channel, that is, channel selection, based on the control of the CPU 71, and outputs received data to the demodulation unit 80. Note that the configuration of the tuner 79 can be appropriately changed or extended according to whether the transmitted broadcast wave is analog data or digital data. The demodulation unit 80 demodulates the digitally modulated received data, and outputs the demodulated data so the decoder 81.

For example, in the case of digital broadcasting, the digital data received by the tuner 79 and demodulated by the demodulation unit 80 is AV data compressed in a predetermined system such as MPEG2 (Moving Picture Experts Group 2) system, and is a transport stream in which the data for data broadcasting is multiplexed. The former AV data is video data and audio data that configure the main body of the broadcast program, and the latter data for data broadcasting includes data accompanying the main body of the broadcast program (for example, the EPG data.

The decoder 81 separates the transport stream supplied from the demodulation unit 80 into, for example, the AV data compressed in the MPEG system and the data for data broadcasting. The separated data for data broadcasting is supplied to the HDD 78 through the bus 74 and the input/output interface 75, and is recorded in the HDD 78.

When it is instructed that a received TV program is output as is, the decoder 81 further separates the AV data into compressed video data and compressed audio data. The separated audio data is decoded, and is them output no a speaker of the television receiver 12 through a mixer 83. Further, the separated video data is expanded, and is then output to a monitor of the television receiver 12 through a composer 82.

When it is instructed that the received TV program be recorded in the HDD 78, the decoder 81 outputs the AV data before separation to the HDD 78 through the bus 74 and the input/output interface 75. When it is instructed that the TV program recorded in the HDD 78 is reproduced, the decoder 81 receives an input of the AV data from the HDD 78 through the input/output interface 75 and the bus 74, separates the data into compressed video data and compressed audio data, and outputs the data to the composer 82 and the mixer 83, respectively.

The composer 82 composes the video data input from the decoder 81 and a GUI (graphic user interface) screen, as necessary, and outputs the composed data to the monitor of the television receiver 12.

The devices 22 to 25 of FIG. 1 are configured from mobile terminals, such as so-called smart phones. FIG. 3 is a block diagram illustrating a configuration example of the device 22 of FIG. 1.

In FIG. 3, a CPU (Central Processing Unit) 101 executes various types of processing according to a program stored in a ROM (Read Only Memory) 102 or a program loaded into a RAM (Random Access Memory) 103 from a storage unit 108. Further, data and the like necessary for the CPU 101 to execute various types of processing are also appropriately stored in the RAM 103.

For example, the FishView is executed in the device 21, so that images of the sea and the fish are displayed on the display, and communication with other devices is performed, so that the images are successively updated.

In this way, the service of the fishing game is provided.

Other than the above-described games, services, such as a fighting game in which characters of the users fight with each other, a roll playing game, and the like, are provided.

FIG. 8 is a diagram describing an example in which a plurality of services is provided in the same LAN. In this example, a service of a car race game and a service of a fighting game are provided.

The CarApp is executed in the device 23, and the user of the device 23 participates in the car race game. Note that, while the CarApp is incorporated in the device 22, assume that the CarApp has not been executed.

The users of the devices 24 and 25 participate in a fighting game. FightApp is incorporated in the devices 24 and 25, and the users of the devices 24 and 25 play in the fighting game. Note that the FightApp is a program configured as the above-described RD-App, and in which various types of control concerning the mobile terminals operated by the users in the fighting game are described.

For example, when the device 22 is activated, the fact of the activation is notified so the device 23, and data for prompting initiation of the CarApp is transmitted to the device 22 by the application program (CarApp) of the device 23. Further, when the device 22 is activated, the fact of the activation is notified to the devices 24 and 25, and data for prompting installation and execution of the FightApp is transmitted to the device 22 by the application program (FightApp) of the device 24.

That is, a device that has already participated in some sort of service transmits data for prompting participation to the service to a device newly connected to the LAN. Note that, when a plurality of users participates in one service, a device of a predetermined representative user transmits the data of prompting participation to the service.

For example, as illustrated in FIG. 9, the device (device 23) having already initiated the application program in the LAN transmits the data for prompting execution (or installation) of the application program to the device 22.

For example, when the data for prompting execution (or installation) of the application program is transmitted from the devices 23 and 24 to the device 22, a screen like the one illustrated in FIG. 10 is displayed on the display of the device 22.

In the example of the screen of FIG. 10, a dialog of “participation-possible service” is displayed. In this screen (GUI), when the user presses (selects) a button 132, the FightApp is installed into the device 22 and is executed. That is, the user of the device 22 participates in the service of the fighting game.

Meanwhile, in the screen of FIG. 10, when the user presses (selects) a button 131, the FightApp is not installed into the device 22. That is, the user of the device 22 does not participate in the service of the fighting game.

In the screen of FIG. 10, when the user presses (selects) a button 142, the CarApp is executed in the device 22. That is, the user of the device 22 participates in the service of the car race game.

Meanwhile, in the screen of FIG. 10, when the user presses (selects) a button 141, the CarApp is not executed in the device 22. That is, the user of the device 22 does not participate in the service of the car race game.

Note that, here, an example has been described, in which a screen (GUI) as illustrated in FIG. 10 is displayed, and participation and non-participation to the service is selected. However, the participation or non-participation to the service may be selected by another system. For example, when each device has an audio recognition function, the participation or non-participation to the service may be selected by recognizing a voice of the user.

As described above, the devices 21 to 25 incorporates the RD-Agent therein, The RD-Agent is software that is a base for constructing a system, and is operated regardless of OS of the devices 21 to 25. The RD-Agent automatically performs communication with the RD-Agent incorporated in other devices, for example, provides various types of information to the RD-Agent of other services, and acquires various types of information from the RD-Agent of other devices.

The RD-App executed in the devices 21 to 25 is described using RD-Library. The RD-Library is a library for calling a function of the RD-Agent from the RD-App.

The RD-Library provides an API for executing the function of the RD-Agent as one like the following functions.

For example, the function “RD_init( )” is a function used when initializing information concerning service information and notifying the own service information to the RD-Agent of other devices. Note that the service information will be described below.

Further, the function “RD_getinfo( )” is a function used when acquiring RD device information of other services connected to the LAN. Note that the RD device information will be described below.

Further, the function “RD_getsvinfo( )” is a function used when acquiring service information of a service in which the other devices connected to the LAN participate.

Further, the function “RD_request( )” is a function used when requiring other devices to perform installation or execution of predetermined RD-App.

For example, as illustrated in FIG. 11, the RD-Agent and the RD-App are executed in each device, the RD-App is described using the RD-Library, and the function of the RD-Agent is called by the RD-Library. Then, for example, a service a is provided, to which a plurality of devices having RD-App_a1 and RD-App_a2 in execution participates, and a service b is provided, to which a plurality of devices having RD-App_b1 and RD-App_b2 in execution participates.

The RD-Agent provides the RD-Agent of other devices with information like the one illustrated in FIGS. 12 and 13.

FIG. 12 is a diagram illustrating an example of the RD device information. The RD device information is unique information concerning the devices 21 and 22, for example.

In the example of FIG. 12, an “IP address”, a “device name”, “platform information”, “hardware information”, and the like are included in the RD device information. The “platform information” includes, for example, OS of the device in which the RD-Agent is incorporated, a version of the OS, CPU architecture, and the like. Other than the above, information such as a Class name of Java (registered trademark) and a file pass of Windows (registered trademark) may be included in the “platform information”.

The “hardware information” of FIG. 12 includes, for example, a “screen size” of the device in which the RD-Agent is incorporated, “incorporated interface information”, and the like. The “incorporated interface information” includes information such as the number of hardware keys, an upper limit of multi touch of a touch panel, the existence of a GPS, the existence of a video camera, and the like.

FIG. 13 is a diagram illustrating an example of the service information. The service information is information concerning the RD-App executed in the device in which the RD-Agent is incorporated.

In the example of FIG. 13, a “service name (for example, a mah-jong game)”, a “service outline (in which game content and the like are described, for example)”, the “RD-App”, “RD-App information related to the service”, and the like are included, in the service information.

The “RD-App information related to the service” is, for example, a region in which information concerning various types of RD-App used for the service of the mah-jong game is described, and the name of the application (RD-App) is described. For example, in the case of the service of the mah-jong game, the MjApp_A and the MjApp_B are described as the names of the application. URL of each RD-App specified by the name of each application according to the platform information of the device is described.

For example, URL_A is described as URL for downloading the RD-App to be installed in a device of the version 1, having OS made by a company A. Further, URL_B is described as URL for downloading the RD-App to be installed in a device of the version 2, having OS made by a company A. In this way, the URL according to the platform information of each device is described in the “RD-App information related to the service”.

For example, in the example of FIG. 8, when the RD-Agent of the device 22 is executed, the RD-Agent of the device 22 transmits the own RD device information to the devices 21, 23 to 25. Accordingly, the RD-Agent of the device 21, 23 to 25 recognize the existence of the RD-Agent of the device 22. Further, the device information is transmitted from each RD-Agent of the devices 21, 23 to 25 to the device 22. Accordingly, the RD-Agent of the device 22 recognizes the existence of the RD-Agent of the devices 21, 23 to 25.

Then, the RD-Agent of the device 23 checks the device information of the device 22, and determines whether the device 22 can participate in the service of the car race game. When the device 22 can participate in the service of the car race game, the RD-Agent of the device 23 transmits the service information to the device 22. Similarly, the RD-Agent of the device 24 checks the device information of the device 22, and determines whether the device 22 can participate in the service of the fighting game. When the device 22 can participate in the service of the fighting game, the RD-Agent of the device 24 transmits the service information to the device 22.

Here, the service information transmitted from the devices 23 and 24 to the device 22 is, for example, configured as packet data in a predetermined format, and is transmitted as data for prompting the users of other devices to participate in the service (participation asking data).

Accordingly, a screen as described above with reference to FIG. 10 is displayed on the display of the device 22. For example, when the user of the device 22 presses the button 132 of FIG. 10, the RD-Agent of the device 22 checks the “RD-App information related to the service” in the service information, and acquires the URL according to the platform information of the device in which the RD-Agent itself is operated. Then, the RD-Agent of the device 22 downloads the RD-App based on the URL, and installs and executes the RD-App. In this way, the user of the device 22 can participate in the service of the fighting game by simply pressing the button 132.

As described above, according to the present technology, when there is a plurality of services (for example, online games) provided on the LAN, for example, the user can arbitrary select which service he/she' s going to participate.

Alternatively, assuming that, in the example of FIG. 8, the RD-Agent of the device 22 is executed, the screen of the FIG. 10 is displayed, and the buttons 131 and 141 are pressed. Note that, when the RD-Agent of the device 22 is executed, the RD-Agent of the device 22 transmits the own RD device information to the devices 21, 23 to 25, and the RD-Agent of the devices 21, 23 to 25 respectively transmit the own device information to the device 22.

Further, when the FishCtrl is executed in the device 22, the RD-Agent of the device 22 transmits the service information.

At this time, for example, the RD-Agent of the device 22 checks the device information of the devices, and determines whether the devices can participate in the service of the fishing game. For example, when the devices 24 and 25 can participate in the service of the fishing game, the RD-Agent of the device 22 transmits the service information to the devices 24 and 25. Here, the service information transmitted from the device 22 to the devices 24 and 25 is also configured as packet data in a predetermined format, for example, and is transmitted as data for prompting the users of other devices to participate in the service (participation asking data).

Accordingly, a GUI that prompts the participation to the service of the fishing game is displayed on the displays of the devices 24 and 25.

In this way, according to the present technology, a user of a device connected to the network later can invite a user who has already participated in some sort of service to participate service that the later connected user desires.

In addition, as described above, according to the present technology, the application program and the like required for various services can be easily installed and executed. For example, the time and effort such as the user checking the version of the application program and installing the program each time like the past technologies, can be omitted. Further, for example, the developer of the application program can easily design the processing performed in cooperation with the application programs executed in other devices.

Therefore, according to the present technology, a number of variations in functions can be realized using a plurality of devices connected to the network.

FIG. 14 is a flowchart describing processing of the RD-Agent. This processing is executed when the devices 21 to 25 are activated, and the RD-Agent is executed.

In step S21, the RD-Agent transmits the RD device information of the device in which the RD-Agent itself is incorporated to other devices connected to the LAN.

In step S22, the RD-Agent receives the RD device information of other devices connected to the LAN.

In step S23, the RD-Agent determines whether the service information has been received from other devices. In step S23, when it is determined that the service information has not been received from other devices, the processing proceeds to step S25.

That is, when no invitation of participation to a service has been given from the users of other devices, the RD-Agent prompts other devices to participate in a service that the RD-Agent itself desires (a service corresponding to the RD-App to be executed afterwards).

In step S25, the RD-Agent determines whether the RD-App has been executed in the device in which the RD-Agent itself is incorporated. In step S25, when it is determined that the RD-App has been executed, the processing proceeds to step S26.

In step S26, the RD-Agent identifies a device to which the service information is to be transmitted based on the RD device information of other devices received in the processing in step S22. At this time, for example, a device to which the service information is to be transmitted is identified based on the information on described in the “platform information” and the “hardware information” of FIG. 12.

Alternatively, a device to which the service information is to be transmitted may be identified based on a setting file. For example, whether participation to a service is prompted according to the transmitted RD device information and service information is described in the setting file previously stored in the device in which the RD-Agent is incorporated. For example, a device having the IP address of AAAA is set not to prompt participation to a OO service. In this case, a device to which the participation is prompted becomes identified according to the type of service.

In step S27, the RD-Agent transmits the service information to the device identified in the processing of step S26.

Note that the processing of steps S26 and S27 is executed by the RD-App controlling the function of the RD-Agent using the RD-Library.

Meanwhile, in step S23, when it is determined that the service information has been received from other devices, the processing proceeds to step S24. In step S24, the RD-Agent executes participation appropriateness determination processing described below with reference to FIG. 5.

Here, a detailed example of the participation appropriateness determination processing of step S24 of FIG. 14 will be described with reference to the flowchart of FIG. 15.

In step S51, the RD-Agent checks the service information that has been determined to be received in step S23.

In step S52, the RD-Agent determines whether the RD-App has been installed.

At this time, for example, the RD-App required for participating in the service is identified based on the “RD-App information related to the service” of FIG. 13, and whether the RD-App has been installed (whether already been incorporated) in the device in which the RD-Agent itself is incorporated is determined.

In step S52, when it is determined that the RD-App has not been installed, the processing proceeds to step S53.

In step S53, the RD-Agent acquires URL for downloading the RD-App. At this time, for example, the “RD-App information related to the service” in the service information is searched and the URL is identified based on the information described in the “platform information” and the “hardware information” of the RD device information of the device in which the RD-Agent itself is incorporated.

In step S54, the RD-Agent determines whether participation to a service corresponding to the service information that has been determined to be received in step S23 has been commanded. In step S54, when it is determined that the participation to the service has been commanded, the processing proceeds to step S55.

For example, a screen like the one illustrated, in FIG. 10 is displayed on the display of the device in which the RD-Agent is incorporated, and when the buttons 132 and 142 are selected, it is determined that the participation to the service has been commanded. Meanwhile, when the screen like the one illustrated in FIG. 10 is displayed and the buttons 131 and 141 are selected, it is determined that the participation to the service has not been commanded.

Alternatively, whether the participation so the service has been commanded may be determined based on a setting file. For example, appropriateness of the participation is described in the setting file previously stored in the device in which the RD-Agent is incorporated according so the transmitted RD device information, service information, and the like.

For example, when an invitation to a service of a car race game is given, it is set that the invitation is always rejected. When an invitation to a service of a fighting gage is given, and it is set to always participate in the service. In this case, participation to the service of a fighting game is commanded without displaying a screen like the one illustrated in FIG. 10. In the example of FIG. 3, the FightApp is installed and executed in the device 22, and the user of the device 22 participates in the service of the fighting game.

Further, for example, when an invitation of participation to a service is given by the device having the IP address of AAAA, it is set to always participate in the service, and when an invitation of participation to a service is given by the device having the IP address of BBBB, it is set that the invitation is always rejected. For example, when an invitation of participation to a service is given by the device 23, it is set that the invitation is always rejected, and when an invitation of participation to a service is given by the device 24, it is set to always participate in the service. In this case, for example, the participation to the service to a fighting game is commanded without displaying a screen like the one illustrated in FIG. 10. In the example of FIG. 8, the FightApp is installed and executed in the device 22, and the user of the device 22 participate in the service of the fighting game.

In step S55, the RD-Agent downloads the RD-App based on the URL acquired in the processing in step S53.

In step S56, the RD-Agent installs the RD-App downloaded in the processing in step S55 to the device in which the RD-Agent itself is incorporated.

In step S57, the RD-Agent executes the RD-App installed in step S56.

Meanwhile, in step S54, it is determined that the participation to the service has not been commanded, the processing of steps S55 to S57 is skipped.

Further, in step S52, it is determined that the RD-App has been installed, the processing proceeds to step S58.

In step S58, the RD-Agent determines whether participation to a service corresponding to the service reformation that has been determined to be received in step S23 has been commanded.

For example, when a screen like the one illustrated in FIG. 10 is displayed on the display of the device in which the RD-Agent is incorporated, and the buttons 132 and 142 are selected, it is determined that the participation to the service has been commanded. Meanwhile, when a screen like the one illustrated in FIG. 10 is displayed, and the buttons 131 and 141 are selected, it is determined that the participation to the service has not been commanded.

Alternatively, whether the participation to the service has been commanded may be determined based on a setting file. For example, appropriateness of participation may be described in the setting file previously stored in the device in which the RD-Agent is incorporated according to the transmitted RD device information, service information, and the like.

In step S58, when it is determined that the participation to the service has been commanded, the processing proceeds to step S59.

In step S59, the RD-Agent executes the RD-App installed in advance.

Meanwhile, in step S58, when it is determined that the participation to the service has not been commanded, the processing of step S59 is skipped.

After the processing of step S57 or S59, the participation appropriateness determination processing ends. Accordingly, the processing of the RD-Agent of FIG. 14 ends.

Note that, when it is determined that the participation to the service has not been commanded in step S54, or when it is determined the participation to the service has not been commanded in step S58, the processing may proceeds to step S25 of FIG. 14.

That is, when all of the participation to the services from the users of other devices are rejected, participation to a service may be prompted from the RD-Agent itself to the users of other devices.

In this way, the processing of the RD-Agent is executed.

In the above description, an example has been described, in which devices incorporates the RD-Agent therein are connected on the LAN. However, for example, the devices may be connected through a WAN, so that a VLAN (Virtual LAN) may be configured.
