Description

  The present invention relates to a remote application technique for displaying or operating an application that runs on a server device on a terminal connected via a network.

  With the spread of home networks, it has become common to connect PCs and digital AV devices to mutually use still images, moving images, music data, and the like. There is a Digital Living Network Alliance (DLNA) as a guideline for such digital device cooperation, and media servers and media players that comply with the DLNA guideline have been commercialized. The media player is client software that connects to a media server to acquire and reproduce video and audio.

  As a media player mounting method, there is a remote desktop or a remote application. In this case, display and operation of an application running on a PC are performed on a remote display device via a network. As technologies related to such remote applications, there are Media Center (R) and Media Center Extender (R) of Microsoft (R). For example, when watching a continuation of a movie that was watched in one room in another room or watching a continuation of a movie being watched on a large-screen TV on a small-screen mobile device, etc. It is assumed that it will be used.

  Patent Documents 1 and 2 are examples relating to the transition of such display terminals and operation terminals. Japanese Patent Application Laid-Open No. 2004-151561 confirms an ID of a notebook PC stored in the docked PC at the time of connection in a docked PC that can use the resources of the notebook PC by connecting the notebook PC, and permits the use.

  On the other hand, Patent Document 2 reads software resources that were operating on a notebook PC before connection into a docked PC, so that the software on the notebook PC can be operated on the docked PC after connection. At that time, the system resources are reconfigured so that the software that was running on the PC with the dog also runs simultaneously.

Furthermore, in a digital camera that is widely used in general, a list of captured images can be confirmed using a display on the back. In addition, once an image is collectively transmitted by connecting to a PC via a USB (Universal Serial Bus), the image can be continuously confirmed on the screen of the PC. Furthermore, there is a known technique for performing direct printing without using a PC by connecting a digital camera and a printer via USB. As described above, Patent Documents 3 and 4 disclose examples of changing the operation mode of the digital camera or changing the display on the rear display when the USB connection is made.

  The techniques disclosed in Patent Documents 3 and 4 can be considered as a technique for transferring a content browsing terminal from a camera to a PC by connecting the camera to a PC via USB. However, the content browsing software running on the camera and PC is completely different. For this reason, the display state and operation state of the browsing software are not inherited before and after the transition.

  On the other hand, in the techniques disclosed in Patent Documents 1 and 2, since the resource is handed over to the migration destination PC, the user also takes over the usage state of the application software (hereinafter simply referred to as an application). Can continue to use. Further, by registering connectable notebook PCs, unlimited use can be prevented.

  However, in the case of a system in which the application execution environment and the display environment are connected via a network, the configuration is different from Patent Documents 1 and 2, and thus the same method cannot be used.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings.

<First Embodiment>
In the present embodiment, a technique will be described in which, in a remote application (hereinafter simply referred to as “remote app”) environment, the display / operation terminal is simply shifted while maintaining the state of the remote app. The remote application environment is an environment in which an application software execution device and a display / operation device are connected via a network. In this embodiment, at the time of migration, the migration source display device is connected to the migration destination display device using short-distance communication means such as USB, and network setting information and authentication setting information of the migration destination display device are acquired. . Then, by transmitting these pieces of information to the remote application execution device via the migration source display device, connection / authentication processing is automatically performed between the remote application execution device and the migration destination display device.

  FIG. 1 is a configuration diagram of an information processing system according to the first embodiment of the present invention. The information processing system includes display devices 130 and 140 and a remote application execution device 200. The display device 130 is a large-screen display device such as a digital television, for example, and functions as a first information processing device. The display device 140 is a portable display device such as a mobile phone or a small game machine, and functions as a second information processing device.

  The remote application execution device 200 is a general-purpose personal computer, and includes a network interface (not shown) that can be connected to a network to which the display devices 130 and 140 are connected. The remote application execution device 200 functions as a server device, and the network interface functions as a fifth interface. Further, it is assumed that the remote application is a media player that browses moving images, photos, and the like, and the remote application that operates on the remote application execution device 200 is displayed on the display device 130.

  Here, it is assumed that display / operation of a remote application is transferred from the display device 130 to the display device 140. When migrating, authentication information (for example, network setting information or authentication setting information) including information indicating the location of the display device 140 on the network is required. The network setting information uniquely identifies a position on the network, and is information such as a URI (Uniform Resource Identifier). The authentication setting information is necessary for establishing a trust relationship with the display device 140, and refers to, for example, information such as an authentication key of several bytes. Normally, these pieces of information need to be manually input to the remote application execution device 200. In this embodiment, as will be described later, transfer of these pieces of information is automated using a short-range communication connection.

  As a result of the shift, the display on the display device 130 is stopped and the display on the display device 140 is started. At this time, the display screen of the media player executed by the remote application execution device 200 is updated for a small display terminal which is the display device 140. For example, the display device 130 displays a list of moving images 134, photos 135, and programs 136, but the display device 140 displays only photos. However, in both display devices 130 and 140, the focus 136 and 146 are located in the same photograph, and the application state is maintained before and after the transition.

  FIG. 2 is a diagram illustrating a configuration of the display device 100 according to the first embodiment. The display device 100 can employ a configuration logically similar to the display device 130 and the display device 140. The display device 100 includes a CPU 101, a GPU (Graphic Processing Unit) 102, a ROM 103, a RAM 104, a memory control unit 105, and an I / F control unit 106, each connected to a memory bus 107. The memory control unit 105 controls the memory bus 107. The I / F control unit 106 is connected to an I / F bus 108 for performing input / output with the outside.

  A display I / F 110, an operation I / F 112, an external storage I / F 114, a USB I / F 116, and a network I / F 117 are connected to the I / F bus 108. These external interfaces are performed by the I / F control unit 106 as described above.

  A display device 111 such as a display is connected to the display I / F 110, and an operation device 113 such as a mouse, a keyboard, and various dedicated controllers is connected to the operation I / F 112. In addition, an external storage device 115 such as an HDD or a DVD player is connected to the external storage I / F 114. The network I / F 117 is connected to a network such as a LAN or a WAN. The network I / F 117 functions as a first interface or a third interface, and the USB I / F 116 functions as a second interface or a fourth interface.

  Such a display device can be realized by using a technique similar to that of already commercialized PCs and game machines. Further, the hardware configuration of the remote application execution device 200 is almost the same as that of the display device, and can be easily realized using a commercially available PC, and thus description thereof is omitted.

  3 and 4 are diagrams conceptually showing an operation procedure between the devices constituting the information processing system.

  The display device 130 includes software modules of an overall control unit 131, a remote application display unit 132, and a USB communication unit 133. In addition, the display device 140 includes software modules of an overall control unit 141, a remote application display unit 142, and a USB communication unit 143.

  The remote application execution device 200 includes an overall control unit 201 and a remote application execution unit 202. Remote application execution device 200, display device 130, and display device 140 are each connected by a long-distance communication method such as a LAN. Here, as in FIG. 1, a case is assumed in which display and input operations are transferred from the display device 130 to the display device 140 with respect to a remote application operating on the remote application execution device 200.

  First, in step S301, the display device 130 is USB-connected to the display device 140. Here, the USB communication unit 143 of the display device 140 operates as a USB host, and the USB communication unit 133 of the display device 130 operates as a USB device to detect connection.

  Next, the information of the display device 140 is transmitted to the display device 130 in step S302. The transmitted information includes a URI (Uniform Resource Identifier) of the display device 140 and an authentication key. The URI is a character string indicating the position on the network of a file in which device information of the display device 140 is described, for example. The authentication key is, for example, a character string consisting of a multibyte alphanumeric symbol.

  Here, unlike a long-distance communication method such as a LAN, a short-distance communication method such as a USB can directly specify a communication partner, and therefore it is preferable to transmit information via a USB. For this reason, for example, a USB connection is made between two devices via a cable or a connector.

  However, in the case of a LAN, since the connection target is wide, it may be difficult to associate the logical device searched on the network with the actual device. If you are connected to the Internet in the first place, the search range of the device is unclear, so there is a risk of mishandling. On the other hand, according to the short-distance communication method such as USB, since it is connected to a device at hand, it can be designated as a remote application migration destination safely and securely.

  In the present embodiment, the description has been made centering on USB, which is a short-range communication method. However, the short-distance communication method is not limited to USB. For example, a communication method such as IEEE 1394, RS-232C, IrDA, Bluetooth, Wireless USB, or the like can be adopted. Further, it is possible to mount by communication via a memory medium such as a Compact Flash or an SD card.

  Next, in step S303, information on the display device 140 is transmitted from the display device 130 to the remote application execution device 200 via the LAN. This communication is transmitted from the overall control unit 131 of the display device 130 to the overall control unit 201 of the remote application execution device 200. On the other hand, the remote application execution apparatus 200 acquires device information of the display apparatus 140 from the specified URI in step S304. The acquired device information is a state variable list such as the screen size and processing capability of the display device 140, and the remote application execution device 200 can receive changes in these state variables as events after connection. Such a device capability acquisition and control mechanism can be implemented using UPnP (Universal Plug and Play).

  When the device information is thus acquired and confirmed to be a display device, the remote application execution device 200 performs an authentication process with the display device 140. This is processing for permitting display of a remote application, which is executed by the display device 140 by the remote application execution device 200. For example, the authentication key acquired via the display device 130 is transmitted to the display device 140. On the other hand, in step S306, the display device 140 determines whether or not the authentication key is the same as the authentication key transmitted to the display device 130 in advance.

  If the authentication is successful, the remote application execution device 200 performs a process of switching the display destination of the remote application from the display device 130 to the display device 140 in step S307. Prior to the actual processing, in step S308, the display device 130 is notified of the end of display. In step S309, display of the remote application on the display device 130 is stopped, and display of the remote application on the display device 140 is started in step S310. At this time, the remote application execution unit 202 changes the screen according to the resolution of the display screen of the display device 140.

  The procedure described above will be described in detail with reference to FIG. First, in step S401, the display device 130 makes a USB connection to the display device 140. In step S402, the display device 140 detects the USB connection, and establishes the USB connection in step S403. In the description here, the display device 130 is a USB device and the display device 140 is a USB host. However, the display device 140 may be a USB device and the display device 130 may be a USB host.

  When the display devices 130 and 140 are connected by USB, the display device 130 requests device information from the display device 140 in step S404. The device information is the URI or authentication key of the display device 140 as described with reference to FIG. In step S <b> 405, the display device 140 transmits device information to the display device 130.

  Next, in step S406, the display device 130 transmits device information regarding the display device 140, which is a display and operation transfer destination, to the remote application execution device 200. Next, the remote application execution device 200 acquires detailed device information from the URI of the display device 140 in steps S410 and S411. As described above, detailed device information describes the resolution and display capability of the display screen of the display device 140, controllable variables, and the like.

  When the remote application execution device 200 receives the device information, the remote application execution device 200 performs an authentication process for displaying the remote application running on the remote application execution device 200 on the display device 140. First, in step S412, the remote application execution device 200 requests the display device 140 to start connection. In step S413, the display device 140 requests the remote application execution device 200 for an authentication key. On the other hand, the remote application execution device 200 transmits an authentication key to the display device 140 in step S414. The authentication key is obtained via the display device 130. After confirming the authentication key, the display device 140 sends a connection permission notification to the remote application execution device 200 in step S415.

  Thus far, the preparation for performing display output of the remote application on the display device 140 is completed. In step S416, the remote application execution device 200 notifies the display device 130 that the remote application is to be transferred. In response to this, in step S417, the display device 140 returns a message indicating that it has been received. Finally, in step S418, the execution device ends the remote application session for the display device 130, and starts a remote application session for the display device 140 in step S419.

  FIG. 5 is a diagram illustrating an operation procedure of the display device 130. 5 illustrates the operation procedure of the display device 130, the display device 140 can be described in the same operation procedure. For simplification, FIG. 5 shows an operation procedure centering on a part related to event processing of the overall control unit 131. In the display device and the execution device, other software modules also operate in parallel.

  First, in step S501, it is detected whether a USB connection event has been detected. The USB connection event is notified from the USB communication units 133 and 143. When a USB connection event is detected in step S501, it is determined in step S502 whether the remote application is a migration destination or a migration source. That is, it is determined whether or not the remote application is being executed. If it is determined in step S502 that it is the migration source, device information is acquired from the USB connection partner in step S503. Then, the device information acquired in step S504 is transmitted to the remote application execution apparatus 200, and the series of processes is terminated.

  On the other hand, if it is determined in step S502 that the destination is the remote application migration destination, the device information is then requested from the connection partner, so the device information is transmitted to the connection partner in step S505, and the series of processing ends. To do.

  If it is determined in step S501 that a USB connection event has not been detected, it is determined in step S506 whether the event is a remote application display start event. This is a request from the remote application execution device 200 to start displaying an application. If it is determined in step S506 that the event is a remote application display start event, authentication processing is performed in step S507. This requests an authentication key from the remote application execution device 200, and the remote application execution device 200 returns this, so it is determined whether or not an authentication key has been issued. This corresponds to steps S413 to S415 in FIG. Then, the success or failure of the authentication is returned to the remote application execution device 200, and the series of processes is terminated.

  If it is determined in step S506 that the event is not a remote application display start event, it is determined in step S508 whether the event is a remote application display end event. If it is determined in step S508 that the event is a remote application display end event, connection end processing is performed in step S509, and a series of processing ends. This is, for example, a process of displaying that the execution of the application has ended in a dialog on the display device side, and once ending the display after confirmation. If it is determined in step S508 that the event is not a remote application display end event, other event processing is performed in step S510, and the series of processing ends.

  FIG. 6 is a diagram illustrating an operation procedure of the remote application execution device 200. Here, for the sake of simplification, the operation procedure will be described with a focus on the event processing of the overall control unit 201.

  First, in step S601, it is determined whether it is a remote application migration request event. This event occurs when requested by the display device 130 via the network. If it is determined in step S601 that the event is a migration request event, in step S602, information regarding the display device 140 that is the migration destination is acquired from the display device 130 that is the migration source of the remote application. In step S603, device information is acquired with reference to the URI of the display device 140.

  Thereafter, a remote application display session start request is sent to the display device 140 in step S604. On the other hand, since authentication information is required from the display device 140, an authentication key is transmitted in step S605. Next, in step S606, it is determined whether authentication is successful. If it is determined in step S606 that the authentication is successful, in step S607, the display device 130 that is the transfer source is notified of the transfer success. On the other hand, if it is determined in step S606 that the authentication has failed, the series of processing ends.

  Thereafter, the display of the remote application on the display device 130 is stopped in step S608, and the display of the remote application is started on the display device 140 in step S609. Here, the display format is changed as shown in FIG. 1 in accordance with the screen size, resolution, and input means of the transfer destination display device. A user interface of application software is provided from the display device 140 to the remote application execution device 200 via a network. When all the processes are completed, the next event is waited for. By such processing, it is possible to display the remote application and transfer the operation terminal from the display device 130 to the display device 140.

  As described above, according to the present embodiment, display / operation can be transferred to a different display terminal while maintaining the display and operation state of the application in the remote application execution / display environment. At that time, the migration source terminal is connected to the migration destination terminal via USB, and information on the migration destination terminal acquired via USB is transmitted to the remote application execution device via the migration source terminal. Thereby, it is not necessary to manually input the network connection setting and authentication key of the transfer destination, and the transfer process can be performed automatically. Also, by designating via USB, it is possible to prevent the display from shifting to an unexpected device.

<Second Embodiment>
In the first embodiment described above, the remote application display destination automatically shifts. In this embodiment, the convenience of the user is improved by inquiring the user whether or not to perform the shift. Different. In addition, about the structure similar to 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  That is, when a connection is detected, a dialog for confirming whether or not to move is displayed on the screen of the display device to confirm the user's intention. This dialog is normally displayed on the display device 130 that is the migration source, but may be displayed on the display device that is the migration destination.

  This is particularly effective when a connection is made automatically in a short-range communication system using radio. The short-range communication method using wireless assumes wireless connection within a distance range of several meters to 10 meters, such as Bluetooth and Wireless USB. Since any means can automatically detect a device, communication is possible only by being close to each other.

  FIG. 7 is a diagram illustrating an operation procedure of the display device 130 according to the second embodiment. 7 illustrates the operation procedure of the display device 130, the display device 140 can be described in the same operation procedure. For simplification, FIG. 7 shows an operation procedure centering on a part related to event processing of the overall control unit 131.

  First, in step S701, it is determined whether it is a short-range wireless connection establishment event. If it is determined in step S701 that the event is not a short-range wireless connection establishment event, other event processing is performed in step S710, and the series of processing ends. On the other hand, if it is determined in step S701 that the event is a short-range wireless connection establishment event, it is determined in step S702 whether or not it is the migration source. Here, it is assumed that the determination as to the migration source or the migration destination is performed in the same manner as in the first embodiment.

  If it is determined in step S702 that it is the migration source, a migration confirmation dialog is displayed in step S703. The character string displayed in this dialog is, for example, “Another display terminal B has been detected. Do you want to transfer the remote application operation to the display terminal B?”. The user presses a button such as “Yes”, “No”, or “Cancel”.

  Thereafter, in step S704, it is determined whether or not the user has instructed migration. If it is determined in step S704 that an instruction to shift is issued, terminal information is acquired by short-range wireless communication in step S705. In step S706, device information is transmitted to the remote application execution apparatus 200.

  On the other hand, if it is determined in step S704 that it has not been instructed to move, a series of processing is terminated and the next event is awaited. Step S705 is the same processing as step S503, and step S706 is the same processing as step S504.

  If it is determined in step S702 that it is not the migration source (that is, the migration destination), a migration confirmation dialog is displayed in step S707. In this case, “Another display terminal A has been detected. Do you want to allow transfer of remote application operation from the display terminal A?” Or the like. The user again presses one of the buttons “Yes”, “No”, “Cancel”, and the like. Next, in step S708, it is determined whether or not the user has instructed migration. If it is determined in step S708 that a shift instruction has been issued, terminal information is transmitted via short-range wireless communication in step S709. Step S708 is the same processing as step S505. On the other hand, if it is determined in step S708 that the transfer has not been instructed, the series of processes is terminated and the next event is awaited.

  As described above, according to the present embodiment, since the permission of the migration is confirmed on the terminal screen at the time of migration, it is possible to prevent the remote application display terminal from automatically migrating only by detecting the connection. it can.

<Third Embodiment>
In the second embodiment described above, an application transfer is prevented from being performed on an unexpected display terminal by inquiring the user whether or not to perform the transfer. However, in this embodiment, the automatic transfer is performed without inquiring the user. It is different in that it is determined whether or not to shift automatically. In addition, about the structure similar to 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  That is, in this embodiment, a list of terminals that are allowed to be connected is registered in advance in the display device. Then, at the time of short-range communication connection, the registration list is referred to to determine whether to permit or reject the connection.

  Here, the terminal information that is permitted to be migrated includes, for example, a device name and URI information. The connection permission list may be held by the display device 130 that is the migration source, or may be held by the display device 140 that is the migration destination. Also, as a method for performing registration, in the present embodiment, a terminal that has performed display transition of the remote application once in the past is automatically registered. Note that a terminal that the user permits to migrate may be registered in advance.

  FIG. 8 is a diagram illustrating an operation procedure of the display device 130 according to the third embodiment. In this embodiment, the migration permission list is referred to instead of displaying the migration confirmation dialog in steps S703 and S707.

  First, in step S702, it is determined whether or not it is a migration source. If it is determined in step S702 that it is the migration source, the migration permission list is referred to in step S801, and it is determined whether or not it is registered in the migration permission list in step S704. If it is determined in step S704 that it is registered in the migration permission list, the process proceeds to step S705. On the other hand, if it is determined in step S704 that it is not registered in the migration permission list, the series of processing ends.

  On the other hand, if it is determined in step S702 that it is not the migration source (that is, the migration destination), the migration permission list is referenced in step S802, and it is determined whether or not it is registered in the migration permission list in step S708. To do. If it is determined in step S708 that it is registered in the migration permission list, the process proceeds to step S709. On the other hand, if it is determined in step S708 that it is not registered in the migration permission list, the series of processing ends.

  As described above, according to the present embodiment, since it is possible to automatically determine whether or not to allow application migration, it is possible to improve user convenience. Moreover, it is possible to prevent information from leaking due to an application being displayed on an unexpected display device.

  Whether the migration permission list is referred to immediately before step S703 and step S707 in the second embodiment, and a migration confirmation dialog is displayed to allow the user to migrate when there is a display device in the migration permission list. You may make an inquiry about whether or not. In this case, since the check is doubled by the computer and the user, it is possible to more reliably prevent an unexpected display from being displayed.
