Description

  The present invention relates to a communication system, an information processing apparatus, a control device, a controlled device, an information processing method, and a program, and in particular, transmits a message transmitted from the controlled device to the control device in a form enriched. The present invention relates to a communication system, an information processing apparatus, a control device, a controlled device, an information processing method, and a program.

  In recent years, various technologies have been proposed for controlling a recording device at home via a network from a place where the user is away, using a mobile device such as a mobile phone. For example, the user can select a program from an EPG (Electronic Program Guide) displayed on the mobile phone, and set the recording reservation of the selected program over the network.

  In addition, the user can delete a recorded program over the network in response to checking the message transmitted from the recording device by e-mail or the like on the mobile phone.

  Sending a message from a recording device is, for example, when there is not enough free space on the hard disk built in the recording device, so that recording cannot be performed according to the set reservation, or multiple recording reservations are made at the same time zone. This is done when there is a program that cannot be recorded because it is set.

  The user confirms the message and deletes the recorded program (title) from the mobile phone to ensure free space on the hard disk, or delete one of the reservations so that the recording is performed as set. Can do.

Japanese Patent Application Laid-Open No. 2004-133620 discloses a technique that allows a list of reservation information set in a recording device at home to be confirmed over a network using a mobile phone.

  However, since the contents of the information related to the recorded program managed inside the recording device and the information related to the recording reservation program are limited, even if such information is included in the message and notified. It is difficult for the user to determine which title is to be deleted and which recording reservation is to be deleted.

  For example, since there is not enough free space on the hard disk, even if a title list consisting of the program name and recording date / time is included in the message, it is not possible to know the detailed contents of the program, so which title should be deleted It may not be possible to judge.

  In addition, since multiple recording reservations are set in the same time zone, even if the program name and scheduled broadcast date and time of each program for which recording reservations are set are notified, only from such information, It may not be possible to determine which recording reservation should be deleted.

  Some devices are equipped with an automatic recording function that automatically selects a program that suits the user's preference and sets a recording reservation, but in such a device, multiple programs that are broadcast in the same time zone are selected and recorded. When a message is transmitted because the reservation is batting, if a mistake is made in determining which recording reservation is to be deleted, a program that suits the taste will not be recorded.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram illustrating a configuration example of a communication system according to an embodiment of the present invention.

  1 includes a cellular phone 1-1 and a notebook personal computer 1-2 as control devices, service servers 2-1, 2-2, a DAP server 3, and a DVR (Digital Video Recorder) as a control device. It is composed of four.

  Each device is connected to a network. As indicated by arrows in FIG. 1, the control device and the service servers 2-1, 2-2, the service servers 2-1, 2-2, the DAP server 3, and the service server 2-1 and 2-2 and controlled devices, and each device can communicate with each other between the DAP (Direct Access Platform) server 3 and the controlled device.

  The cellular phone 1-1 is a device that is carried by the user, and is also used as a control device that controls the DVR 4 to be controlled over the network.

  In addition to the telephone function unit, the cellular phone 1-1 includes, for example, a CPU (Central Processing Unit) that executes various processes by executing programs, a communication unit that communicates with other devices via a network, an LCD ( A display made up of a liquid crystal display), an operation unit made up of a numeric keypad and a decision button, a storage unit made up of a non-volatile memory, etc.

  In the storage unit of the mobile phone 1-1, various kinds of information such as user identification information assigned to the mobile phone 1-1, registration of the own device with respect to the DAP server 3 and remote recording reservation of a program executed by the CPU are stored. A program or the like for performing processing is stored.

  As the control device, a notebook personal computer 1-2 as shown in FIG. 1 may be used, or a PDA (Personal Digital Assistance) may be used. Hereinafter, although the case where a user uses the mobile telephone 1-1 is mainly demonstrated, it replaces with the mobile telephone 1-1 and the same process is performed also in the other apparatus used as a control apparatus.

  The service servers 2-1 and 2-2 are servers that provide a control device with a service for accessing the controlled device via a network. In the example of FIG. 1, two service servers 2-1 and 2-2 are shown, but for example, more service servers are prepared for each service to be provided. Hereinafter, a case where the service server 2-1 provides a service will be described. Similar processing is performed in the service server 2-2.

  The service server 2-1 is realized by, for example, a computer provided with an input unit such as a keyboard / mouse, a display, a CPU that executes various processes by executing a program, a communication unit, and a storage unit including a hard disk. The storage unit of the service server 2-1 includes a program executed by the CPU to provide a service, a service ID for identifying the service server 2-1 itself and the service provided by the service server 2-1. Remembered.

  The DAP server 3 is a server that centrally manages a correspondence relationship between a combination of a control device and a service received by the control device (a service provided by the service server 2-1) and a controlled device to be controlled. In response to an inquiry from each service server, the DAP server 3 provides information such as an address necessary for the service server making the inquiry to access the controlled device.

  That is, when using a service for controlling a controlled device over a network, the user can obtain information on the mobile phone 1-1 used as the control device and information on the DVR 4 to be controlled using the mobile phone 1-1. It is necessary to register with the DAP server 3 in advance. Details of registration will be described later.

  The DAP server 3 is realized by a computer in the same manner as the service server 2-1. The storage unit of the DAP server 3 stores a program executed by the CPU and information indicating the correspondence between each device.

  As shown in FIG. 1, the DAP server 3 includes a SOAP (Simple Object Access Protocol) server 3-1 and an XMPP (eXtensible Messaging and Presence Protocol) server 3-2.

  The SOAP server 3-1 communicates with the service server 2-1 and the DVR 4 that is the controlled device by SOAP communication, manages the correspondence between the devices, and is necessary for accessing the controlled device. Provide information such as addresses to the service server.

  In SOAP communication, a message with accompanying information called an envelope is exchanged in an XML (eXtensible Markup Language) document by a protocol such as HTTP (Hyper Text Transfer Protocol) and the process proceeds. Since both the client device and the server device have SOAP generation / interpretation engines, it is possible to call objects between different environments.

  The XMPP server 3-2 establishes a bidirectional always-on session with the DVR 4 that is the controlled device by communication using XMPP.

  XMPP is a protocol for realizing real-time communication, and is also used in an instant messenger (Instant Messenger (IM)) service and the like. In the instant messenger service, it is checked whether or not an IM client is online on the Internet, and chat and file exchange can be performed between IM clients that are online.

  The DVR 4 incorporates a recording medium such as a hard disk, and has a function of recording content such as a broadcast program on the recording medium and playing back a recorded program. The DVR 4 includes a CPU that executes programs to perform various processes, a communication unit that performs communication via a network, a storage unit that includes a nonvolatile memory, an infrared signal that is output from a remote controller or the mobile phone 1-1, and the like. Is provided.

  The storage unit of the DVR 4 stores a program executed by the CPU for performing processing such as registration of the own device with respect to the DAP server 3 and remote recording reservation of a program. In addition, device authentication information including an ID used for authentication of the DVR 4 is also stored.

  In the example of FIG. 1, the DVR 4 is shown as the controlled device. However, various devices such as a television receiver and a personal computer can be the controlled device.

  In a communication system composed of such devices, as will be described in detail later, the user of the mobile phone 1-1 selects a predetermined program from the EPG displayed on the display of the mobile phone 1-1. When it is instructed to set a recording reservation, the cellular phone 1-1 requests the service server 2-1 to set a recording reservation, and the address necessary for accessing the DVR 4 by the service server 2-1. Is acquired from the DAP server 3.

  In the service server 2-1, the DVR 4 is accessed via the network based on the information acquired from the DAP server 3, and the recording reservation of the program selected by the user of the mobile phone 1-1 is set. The service server 2-1 instructs the DVR 4 to do this.

  As described above, in the service server 2-1, after information such as an address necessary for accessing the DVR 4 is acquired from the DAP server 3, the service server 2-1 accesses the DVR 4 directly rather than via the DAP server 3. Is done. Hereinafter, access performed from the service server 2-1 to the DVR 4 as appropriate is referred to as direct access. The DAP server 3 can be said to be a server that provides a platform (Direct Access Platform) that realizes this direct access.

  In addition, the access performed from the service server 2-1 to the DVR 4 in response to a request from the user of the mobile phone 1-1 will be described as a forward access. A message transmitted from the DVR 4 is transmitted to the DAP server 3, or a message transmitted from the DVR 4 is transmitted to the mobile phone 1-1 via the DAP server 3 and the service server 2-1. Since the access is the starting point, the access is in the reverse direction.

  FIG. 2 is a diagram illustrating an example of reverse access.

  When an event occurs in the DVR 4, as shown in FIG. 2, the DVR 4 transmits a message indicating that to the DAP server 3.

  For example, because recording reservations are set for multiple programs that are broadcast during the same time period, if it is detected that there is a program that cannot be recorded as scheduled, that is recognized as an event. Then, a message including information such as the program name, broadcast date and time, and channel of the program that cannot be recorded is transmitted from the DVR 4 to the DAP server 3.

  In addition, if there is a title to be deleted because the free space of the hard disk built in DVR4 has decreased, this is recognized as an event, and the program name, recording date and time, and data volume of the program to be deleted A message including information such as the above is transmitted from the DVR 4 to the DAP server 3.

  The message transmitted from the DVR 4 also includes information for designating a service server as a message transmission destination. The DAP server 3 that has received the message transmitted from the DVR 4 transmits the message to the service server designated as the transmission destination according to the information included in the message.

  For example, the service server that is the transmission destination is different for each type of event that has occurred in the DVR 4, and in the DVR 4, the event type and the service server that is the message transmission destination are managed in association with each other.

  The association between the event type and the service server to which the message is sent can be changed according to a request from the service server. Access to the DVR 4 from the service server for the change is also performed based on information such as an address managed by the DAP server 3 as appropriate.

  In the communication system of FIG. 1, not only the controlled device is controlled from the control device by the forward access, but also the backward access is performed.

  FIG. 3 is a diagram illustrating an example of an application using reverse access. The case where the transmission destination of the message transmitted from the DVR 4 is the service server 2-1 will be described.

  When an event occurs, the DVR 4 transmits a message to the DAP server 3 as indicated by an arrow # 1 in FIG. The message transmitted from the DVR 4 is transmitted from the DAP server 3 to the service server 2-1, as indicated by arrow # 2.

  The service server 2-1 that has received the message transmitted from the DAP server 3 edits (processes) the message as indicated by arrow # 3. As message editing, for example, different information is added depending on the content of the message. The edited message is richer in content than the pre-edit message sent from the DVR 4.

  For example, when a message including information such as the program name, broadcast date and time, and channel of a program that cannot be recorded is transmitted from the DVR 4, the detailed information of the program, the program rebroadcast schedule Is added. The information added to the message is acquired by the service server 2-1 by performing an Internet search using the program name as a keyword or by selecting from information registered in advance. By performing the search using the program name as a keyword, the information added to the message differs depending on the content of the message.

  The service server 2-1 transmits the edited message to the mobile phone 1-1 as the control device, as indicated by arrow # 4.

  As indicated by arrow # 5, the mobile phone 1-1 displays the edited message transmitted from the service server 2-1, and allows the user to confirm the content of the message.

  Since the user can check the detailed information such as detailed information of programs that cannot be recorded and information on the scheduled rebroadcast of the program, the program name and broadcast date and time managed inside the DVR 4 It is possible to select a program to be recorded easily and accurately compared to the case where only simple information such as is notified.

  For example, if it is learned from a message after editing that a program that has been notified that recording cannot be performed is a program that will be rebroadcast in the near future, it is not necessary to record this time. Or choose not to record the program.

  When an action such as selecting a program not to be recorded is performed by the user, the mobile phone 1-1 requests the service server 2-1 to execute the action selected by the user, as indicated by arrow # 6. .

  The service server 2-1 records information on the action requested from the mobile phone 1-1 as indicated by an arrow # 7 as a history, and after recording the history, the service server 2-1 indicates a DVR 4 as indicated by an arrow # 8. Is directly accessed, and the execution of the action selected by the user is instructed. Information such as an address necessary for performing direct access is acquired by an inquiry to the DAP server 3 as appropriate.

  In the DVR 4, processing corresponding to an instruction from the service server 2-1, that is, an action selected by the user is performed.

  In the communication system of FIG. 1, reverse access is used to realize the above-described application.

  Thereby, the service server 2-1 transmits the message transmitted from the DVR 4 that is the controlled device to the mobile phone 1-1 that is the control device in a form enriched, and notifies the user of the content. Can do.

  Further, the user can respond to the notification from the DVR 4 easily and accurately.

  A series of processes such as editing a message transmitted from the DVR 4 and notifying the user of the edited message will be described later with reference to a flowchart.

  4 is a diagram illustrating an example of an interface of each device constituting the communication system of FIG. In FIG. 4, [IF-**] indicates an interface number.

  The cellular phone 1-1 has an interface [IF-21] that receives access from the service server 2-1. The edited message is notified to the cellular phone device 1-1 through the interface [IF-21].

  The service server 2-1 has an interface [IF-01] that receives access from the mobile phone 1-1 and an interface [IF-05] that receives access from the DAP server 3. For example, the interface [IF-01] notifies the service server 2-1 of a request for action by the user who confirmed the edited message. Further, the interface [IF-05] notifies the service server 2-1 of the pre-edit message transmitted from the DVR 4, information necessary for performing direct access, and the like.

  The service server 2-1 also has an interface [IF-31] that directly receives access from the DVR 4.

  The SOAP server 3-1 of the DAP server 3 has an interface [IF-00] that receives access from the DVR 4 and an interface [IF-02] that receives access from the service server 2-1. A message indicating that an event has occurred is notified from the DVR 4 through the interface [IF-00]. Further, the interface [IF-02] notifies the service server 2-1 of an inquiry about information necessary for direct access.

  The SOAP server 3-1 also includes a SOAP client function. The SOAP client function accesses the interface [IF-05] of the service server 2-1.

  The XMPP server 3-2 of the DAP server 3 has an interface [IF-06] that receives access when establishing an XMPP session from the DVR 4 that is also an XMPP client. After the XMPP session is established, messages can be exchanged bidirectionally between the XMPP server 3-2 and the DVR 4 by using the interface [IF-06].

  The DVR 4 receives an interface [IF-03] for receiving data directly from the cellular phone 1-1 and an access from the XMPP server 3-2 by infrared communication or USB (Universal Serial Bus) standard communication. It has an interface [IF-07] and an interface [IF-09] that receives access from the service server 2-1. A password necessary for device registration is notified from the cellular phone 1-1 through the interface [IF-03], and various information is notified from the DAP server 3 after the XMPP session is established through the interface [IF-07]. Various requests by direct access are notified from the service server 2-1 through the interface [IF-09].

  Similarly to the DVR 4, the router 5 installed in the user's home has an interface [IF-08] that receives access from the DVR 4 as an IGD (Internet Gateway Device).

  In the example of FIG. 4, the storage unit 1-1A provided in the mobile phone 1-1 and stored with the user identification information, and the storage unit 2 provided with the service ID and stored in the service server 2-1. 1A is shown. Also, a storage unit provided in the DAP server 3 and stored in the storage unit 3A and the DVR 4 in which information indicating the correspondence between the combination of user identification information and service ID and device authentication information is stored, and in which the device authentication information is stored. 4A is also shown.

  Here, initial registration performed as a pre-process for forward access and reverse access will be described.

  In order to perform forward access and reverse access, it is necessary for each device to specify which of the devices connected to the network is the device to be communicated with. Information necessary for the identification is registered in the DAP server 3.

  FIG. 5 is a diagram showing the overall flow of initial registration. Details will be described later with reference to a flowchart.

  Initial registration is started when the user instructs to perform initial registration from a menu screen or the like displayed on the display of the mobile phone 1-1 as a control device.

  The initial registration basically includes a process of registering a combination of a control device and a service in the DAP server 3 and a process of registering a combination of the control device and a service and a correspondence between controlled devices in the DAP server 3. The former process is started in response to a request from the mobile phone 1-1.

  When instructed to perform initial registration, the mobile phone 1-1 transmits a registration request to the service server 2-1, as indicated by an arrow # 1 in FIG. The registration request transmitted from the mobile phone 1-1 includes user identification information of the mobile phone 1-1.

  When receiving a request from the mobile phone 1-1, the service server 2-1 transmits a registration request to the DAP server 3 as indicated by arrow # 2. The registration request transmitted from the service server 2-1 includes the service ID of the service server 2-1.

  The DAP server 3 that has received the request from the service server 2-1 generates a registration password, and also represents an ID that represents a combination of the service provided by the service server 2-1 and the mobile phone 1-1 that uses the service (described later). DAP-ID) to be generated, and the generated registration password and ID are registered in association with each other.

  The DAP server 3 transmits and issues the generated registration password to the service server 2-1 as indicated by arrow # 3.

  The registration password issued by the DAP server 3 is transmitted from the service server 2-1 to the mobile phone 1-1 as indicated by arrow # 4 and stored in the storage unit 1-1A of the mobile phone 1-1. The

  By transmitting the registration password to the DVR 4, the user can register the DVR 4 in the DAP server 3 as a controlled device.

  For example, when the user is at home, the output unit of the infrared signal of the mobile phone 1-1 is pointed to the DVR 4 and the transmission of the registration password is instructed, as indicated by arrow # 5, the mobile phone 1-1. Sends the registration password to the DVR 4. At this time, the latter process described above for registering the combination of the control device and the service and the association of the controlled device with the DAP server 3 is started.

  As indicated by arrow # 6, the DVR 4 transmits the ID (device authentication continuation ID described later) assigned by the DAP server 3 together with the registration password to the DAP server 3, and registers itself as a controlled device. Request that.

  When the registration password issued to the service server 2-1 matches the registration password transmitted from the DVR 4, the DAP server 3 uses the service provided by the service server 2-1 and the mobile phone 1- The ID registered as representing one combination and the ID of the DVR 4 are registered in association with each other.

  When the registration of the ID of the DVR 4 is completed, the DAP server 3 transmits a response command to the reception of the registration password to the DVR 4 as indicated by an arrow # 7.

  As a result, the correspondence between the cellular phone 1-1 used by the user as the control device and the service received by the cellular phone 1-1 and the correspondence relationship between the controlled device DVR 4 is registered in the DAP server 3.

  Next, processing of each device at the time of initial registration will be described with reference to the flowchart of FIG.

  Before the request for initial registration is transmitted from the cellular phone device 1-1 to the service server 2-1, device authentication for authenticating the validity of the DVR 4 is performed between the SOAP server 3-1 and the DVR 4.

  That is, in step S31, the DVR 4 transmits a device authentication request including device authentication information stored in the storage unit 4A (FIG. 4) to the SOAP server 3-1. The device authentication information includes the ID of the DVR 4 and the like.

  In step S21, the SOAP server 3-1 receives the device authentication request, and determines whether or not the DVR 4 that has transmitted the device authentication request is a valid device based on the ID included in the device authentication information. For example, whether the ID assigned to the legitimate device is notified to the SOAP server 3-1 in advance, and whether the ID included in the transmitted device authentication information matches the ID notified in advance. Determined.

  If it is determined that the DVR 4 is a valid device, the SOAP server 3-1 generates a device authentication continuation ID to be assigned to the DVR 4, and stores the generated device authentication continuation ID and device authentication information in association with each other in the storage unit 3A. At the same time, in step S22, the device authentication continuation ID and its expiration date information are transmitted to the DVR 4.

  In step S32, the DVR 4 receives the information transmitted from the SOAP server 3-1, and stores the device authentication continuation ID and the expiration date information in the storage unit 4A. Having the device authentication continuation ID indicates that the DVR 4 is a device that has been successfully authenticated by the DAP server 3 (SOAP server 3-1). The DAP server 3 appropriately confirms the authentication status of the DVR 4 that is the controlled device, using the device authentication continuation ID.

  On the other hand, when the user instructs to start the initial registration, in step S1, the mobile phone 1-1 transmits a registration request to the service server 2-1.

  In step S11, the service server 2-1 receives the registration request transmitted from the mobile phone 1-1, and registers the user identification information included in the received request in the storage unit 2-1A.

  In step S12, the service server 2-1 transmits a DAP-ID acquisition request including the service ID stored in the storage unit 2-1A to the SOAP server 3-1. The DAP-ID is an ID uniquely assigned to a combination of a service provided by each service server and a control device receiving the service.

  In step S23, the SOAP server 3-1 receives the DAP-ID acquisition request transmitted from the service server 2-1, and newly generates a DAP-ID. The SOAP server 3-1 registers the generated DAP-ID and the service ID included in the DAP-ID acquisition request transmitted from the service server 2-1 in the storage unit 3 </ b> A in association with each other.

  In step S24, the SOAP server 3-1 transmits the DAP-ID to the service server 2-1.

  In step S13, the service server 2-1 receives the DAP-ID transmitted from the SOAP server 3-1, and associates the received DAP-ID with the user identification information of the mobile phone 1-1 to store the data. Store in 2-1A.

  By storing the DAP-ID in association with the user identification information, the service server 2-1 responds to the user identification information of the cellular phone 1-1 when receiving access from the cellular phone 1-1 thereafter. By requesting the DAP server 3 to perform processing using the DAP-ID, the DAP server 3 can identify the combination of the service of the mobile phone 1-1 that is the control device and the service server 2-1. .

  With the above processing, the DAP-ID for identifying the combination of the service of the mobile phone 1-1 and the service server 2-1 and the service ID of the service server 2-1 are associated with each other and registered in the DAP server 3 become.

  In step S14, the service server 2-1 transmits a registration password issue request to the SOAP server 3-1. The registration password issue request transmitted from the service server 2-1 includes a DAP-ID and a service ID.

  In step S25, the SOAP server 3-1 receives the request transmitted from the service server 2-1.

  When the combination of the DAP-ID and the service ID included in the request from the service server 2-1 is already stored in the storage unit 3A, the SOAP server 3-1 newly generates a registration password, and in step S26 The registration password and the expiration date information are transmitted to the service server 2-1, and the registration password is stored in the storage unit 3A in association with the DAP-ID and the service ID.

  In step S15, the service server 2-1 receives the registration password and the expiration date information transmitted from the SOAP server 3-1.

  In step S <b> 16, the service server 2-1 transmits the registration password and the expiration date information to the mobile phone 1-1.

  In step S2, the cellular phone device 1-1 receives the registration password and expiration date information transmitted from the service server 2-1, and stores the received registration password and expiration date information in the storage unit 1-1A. Remember.

  For example, when the user directs the output unit of the infrared signal of the cellular phone device 1-1 to the DVR 4 and instructs the transmission of the registration password, the cellular phone device 1-1 issues the registration certificate issued from the DAP server 3 in step S3. The password is transmitted to the DVR 4 by infrared communication. In addition to infrared communication, the registration password may be transmitted to the DVR 4 by communication via a USB cable, communication by a wireless local area network (LAN), communication between a contactless IC card and a reader / writer.

  In step S33, the DVR 4 receives the registration password transmitted from the mobile phone 1-1.

  In step S34, the DVR 4 transmits a registration request including the device authentication continuation ID issued when the device authentication is successful and the registration password transmitted from the mobile phone 1-1 to the SOAP server 3-1.

  In step S27, the SOAP server 3-1 receives the request from the DVR 4, and checks whether or not the device authentication continuation ID included in the received request matches that registered in the storage unit 3A; Check the expiration date of the authentication continuation ID. As described above, an expiration date is set for the device authentication continuation ID, and information representing the expiration date is stored in the storage unit 3A at the time of issuance in association with the device authentication continuation ID.

  When it is confirmed that the device authentication continuation ID matches that stored in the storage unit 3A and the expiration date has not expired, the SOAP server 3-1 registers the request included in the request transmitted from the DVR 4 A check is made as to whether or not the registration password matches that registered in the storage unit 3A, and the expiration date of the registration password is checked. As described above, an expiration date is also set for the registration password, and information indicating the expiration date is stored in the storage unit 3A at the time of issuance in association with the registration password.

  When it is confirmed that the registration password matches that registered in the storage unit 3A and the registration password has not expired, the SOAP server 3-1 receives the registration password transmitted from the DVR 4 The DAP-ID and service ID registered in association with the password are associated with the controlled device management ID newly issued as corresponding to the device authentication continuation ID transmitted from the DVR 4. The controlled device management ID is identification information uniquely assigned to each controlled device in the DAP server 3.

  Thereby, the combination of the DAP-ID and the service ID is associated with the controlled device management ID assigned to the DVR 4. The SOAP server 3-1 can identify the controlled device to be controlled based on the DAP-ID, or identify the combination of the controlled device and service used for control based on the controlled device management ID. You can also

  A plurality of controlled device management IDs may be associated with one DAP-ID, or a plurality of DAP-IDs may be associated with one controlled device management ID.

  In step S28, the SOAP server 3-1 transmits a response command to the DVR 4 in response to receiving the registration password. The response command transmitted from the SOAP server 3-1 to the DVR 4 includes information such as the DAP-ID associated with the controlled device management ID of the DVR 4.

  In step S35, the DVR 4 receives the notification from the SOAP server 3-1.

  In step S29, the SOAP server 3-1 notifies the service server 2-1 that the initial registration has been completed.

  In step S17, the service server 2-1 receives the notification from the SOAP server 3-1, and in step S18, transmits a response command to the SOAP server 3-1.

  In step S30, the SOAP server 3-1 receives the response command transmitted from the service server 2-1, and ends the initial registration process.

  With the above processing, the user can register the control device information in the DAP server 3 only by instructing the start of registration from the device to be used as the control device, and receive the registration password. Can do. Further, the user can register the device as a controlled device in the DAP server 3 only by transmitting a registration password to the device to be controlled.

  Next, processing for establishing a constant session between the DAP server 3 and the DVR 4 registered as the controlled device will be described with reference to the flowchart of FIG.

  This process is started at a predetermined timing such as when the power of the DVR 4 changes from the off state to the on state after the DVR 4 is registered in the DAP server 3 as the controlled device.

  In step S41, the DVR 4 requests the SOAP server 3-1 to acquire XMPP login information used for login. The request transmitted from the DVR 4 includes the device authentication continuation ID.

  In step S61, the SOAP server 3-1 receives the request transmitted from the DVR 4, and checks the device authentication continuation ID and the expiration date included in the received request.

  If the device authentication continuation ID matches that registered in the storage unit 3A and the device authentication continuation ID has not expired, the SOAP server 3-1 The control device management ID and device authentication information are searched from the information stored in the storage unit 3A.

  Also, the SOAP server 3-1 uses the XMPP login password used by the DVR 4 to log in to the XMPP server 3-2, information on the expiration date of the XMPP login password, based on the searched controlled device management ID and device authentication information. Information such as an XMPP login destination address and port is generated, and the generated information is stored in the storage unit 3A.

  In step S 62, the SOAP server 3-1 transmits the generated information such as the XMPP login password to the DVR 4.

  In step S42, the DVR 4 receives the information transmitted from the SOAP server 3-1. In step S43, the DVR 4 transmits an XMPP login authentication request including the XMPP login password to the XMPP server 3-2.

  In step S51, the XMPP server 3-2 receives the request from the DVR 4, and checks the XMPP login password and the expiration date of the XMPP login password. The XMPP login password issued to the DVR 4 and information on the expiration date are stored in the storage unit 3A by the SOAP server 3-1.

  If the XMPP login password matches that stored in the storage unit 3A and the expiration date has not expired, the XMPP server 3-2 notifies the DVR 4 that XMPP login is permitted in step S52.

  In step S44, the DVR 4 receives the notification from the XMPP server 3-2. As a result, a session is always established between the DAP server 3 (XMPP server 3-2) and the DVR 4.

  Next, remote recording reservation that is performed using forward access when a session is always established between the DAP server 3 and the DVR 4 will be described.

  FIG. 8 is a diagram showing an overall flow of remote recording reservation. Details will be described later with reference to a flowchart.

  The remote recording reservation is started, for example, when the user selects a predetermined program from the EPG displayed on the display of the mobile phone 1-1 and instructs the DVR 4 to set the recording reservation.

  Next, a process in which the service server 2-1 edits the message transmitted from the DVR 4 and transmits the edited message to the mobile phone 1-1 will be described with reference to the flowchart of FIG.

  When an event occurs in step S251, in step S252, the DVR 4 transmits a device authentication request including device authentication information to the SOAP server 3-1.

  In step S261, the SOAP server 3-1 receives the device authentication request and determines whether or not the DVR 4 that has transmitted the device authentication request is a valid device based on the ID included in the device authentication information.

  If it is determined that the DVR 4 is a valid device, in step S262, the SOAP server 3-1 generates a device authentication continuation ID to be assigned to the DVR 4, and transmits the generated device authentication continuation ID and information on its expiration date to the DVR 4. To do.

  In step S253, the DVR 4 receives the information transmitted from the SOAP server 3-1, and stores the device authentication continuation ID and the expiration date information in the storage unit 4A.

  In step S254, the DVR 4 transmits a message notifying that an event has occurred to the SOAP server 3-1. This message includes, for example, information representing the content of the event, a DAP-ID representing the destination of the message, and a message ID which is the ID of the message itself.

  In step S263, the SOAP server 3-1 receives the message transmitted from the DVR 4, and transmits it to the service server 2-1 in step S264. The fact that the message destination is the service server 2-1 is specified based on the DAP-ID included in the message sent from the DVR 4, for example. The message transmitted from the SOAP server 3-1 to the service server 2-1 includes the number of the DVR 4 that is the transmission source of the message in addition to the information transmitted from the DVR 4.

  In step S271, the service server 2-1 receives the message transmitted from the SOAP server 3-1, and in step S272, edits the message. A specific example of message editing will be described later.

  In step S273, the service server 2-1 transmits the edited message to the mobile phone 1-1.

  In step S281, the cellular phone device 1-1 receives the edited message transmitted from the service server 2-1, and displays it on the display. Thereby, the user can confirm the content of the message edited by the service server 2-1, and can control the DVR 4.

  Next, with reference to the flowchart of FIG. 13, the processing of each device when an operation related to control of the DVR 4 is performed by the user who has confirmed the content of the message will be described. The process of FIG. 13 is the same as the process at the time of the remote recording reservation described with reference to FIG. 9 except that the process of selecting the controlled device is not performed.

  In step S291, the mobile phone 1-1 transmits an action request including information for specifying processing to be performed by the DVR 4 and user identification information to the service server 2-1.

  In step S301, the service server 2-1 receives the action request transmitted from the mobile phone 1-1.

  In step S302, the service server 2-1 transmits an XMPP login request including the service ID, DAP-ID, and DVR4 number to the SOAP server 3-1.

  In step S311, the SOAP server 3-1 receives the request from the service server 2-1, and in step S312, transmits a request for XMPP login to the XMPP server 3-2. The XMPP login request transmitted from the SOAP server 3-1 also includes the service ID, DAP-ID, and DVR 4 number transmitted from the service server 2-1.

  In step S321, the XMPP server 3-2 receives the request from the SOAP server 3-1, and generates an XMPP session ID.

  In step S322, the XMPP server 3-2 stores the generated XMPP session ID in the storage unit 3A in association with the service ID, DAP-ID, and DVR4 number, and transmits the XMPP session ID to the SOAP server 3-1. .

  In step S313, the SOAP server 3-1 receives the XMPP session ID transmitted from the XMPP server 3-2, and transmits it to the service server 2-1 in step S314.

  In step S303, the service server 2-1 receives the XMPP session ID transmitted from the SOAP server 3-1.

  In step S304, the service server 2-1 sends a direct access start request including the service ID, the DAP-ID, the service URN that specifies the service for processing the action requested by the user, and the XMPP session ID to the SOAP server 3- 1 to send.

  In step S315, the SOAP server 3-1 receives the request from the service server 2-1.

  In step S316, the SOAP server 3-1 sends a direct access start request including the service URN transmitted from the service server 2-1 via the session established between the DVR 4 and the XMPP server 3-2. , To the DVR 4 that is the controlled device.

  In step S331, the DVR 4 receives the request transmitted from the SOAP server 3-1 via the XMPP server 3-2 and performs settings for receiving direct access.

  In step S332, the DVR 4 transmits a direct access URI including information such as local port information and a global IP address to the SOAP server 3-1.

  In step S317, the SOAP server 3-1 receives the direct access URI, and in step S318, transmits it to the service server 2-1.

  In step S305, the service server 2-1 receives the direct access URI transmitted from the SOAP server 3-1.

  In step S306, the service server 2-1 performs direct access to the DVR 4 based on the direct access URI, and transmits an action request.

  In step S333, the DVR 4 receives the request transmitted from the service server 2-1, and executes processing instructed by the user in response to the received request.

  When the processing instructed by the user is completed, in step S334, the DVR 4 notifies the processing result to the service server 2-1.

  In step S307, the service server 2-1 receives the notification from the DVR 4, and in step S308, notifies the mobile phone 1-1 that the processing has been completed.

  In step S292, the mobile phone 1-1 receives the notification transmitted from the service server 2-1, and displays the notification on the display to notify the user that the processing has been completed.

  Through the above processing, the user can check the edited message edited by the service server 2-1, and can control the DVR 4 over the network.

  14 and 15 are diagrams showing a specific example of editing a message and examples of actions that can be performed by a user who has confirmed the edited message.

  In the example of FIGS. 14 and 15, as a message transmitted from the DVR 4 when an event occurs, a message notifying that there is a recommended program, a message notifying that there is a newly recorded new title, A message notifying that there is a reservation that cannot be recorded, a message notifying the title to be erased, a message notifying that the hard disk has insufficient free space, and a message notifying that a failure has occurred are shown.

  A message notifying that there is a recommended program is displayed when the DVR 4 is equipped with a function for automatically selecting a program for which a recording reservation is to be set according to the user's preference from programs scheduled to be broadcast. It is transmitted from the DVR 4 at the timing before the reservation setting when the recommended program that matches the preference is selected. The message transmitted from the DVR 4 includes information such as the program name, genre, and performer name of each recommended program.

  When such a message is transmitted, as shown in FIG. 14, the service server 2-1 searches for another program in the same genre as the recommended program and the name of the performer of the recommended program as a keyword. The message is edited by selecting another program in which the same performer appears and adding information on the program so selected as recommended program information.

  The recommended program to be added may be selected from the recommended programs selected by the program provider when the service server 2-1 manages the recommended program selected by the program provider. However, when the service server 2-1 manages a recommended program selected by another user, the recommended program selected by another user may be selected. In addition, if the service server 2-1 or other server manages information about each user's preferences and what programs each user has set for recording reservation, the user of the DVR 4 Other users having similar preferences may be selected from programs set for recording reservation.

  The control unit 15 controls the service server communication unit 11 and transmits an action request according to a user instruction to the service server 2-1.

  FIG. 17 is a block diagram illustrating a configuration example of the service server 2-1.

  The DAP server communication unit 21 communicates with the DAP server 3 and receives, for example, a message transmitted from the DVR 4 and supplied via the DAP server 3. The DAP server communication unit 21 outputs the received message to the message editing processing unit 22.

  The message editing processing unit 22 edits the message transmitted from the DVR 4 as described with reference to FIGS. 14 and 15, and outputs the edited message to the control device communication unit 23.

  The control device communication unit 23 communicates with the mobile phone 1-1, transmits the edited message supplied from the message editing processing unit 22 to the mobile phone 1-1, and confirms the content of the edited message. In response to an instruction from the user, an action request transmitted from the mobile phone 1-1 is received. The control device communication unit 23 outputs the received action request to the device control unit 24.

  When an action request is supplied from the control device communication unit 23, the device control unit 24 controls the direct access processing unit 25 to perform direct access to the DVR 4 and causes the DVR 4 to perform processing according to an instruction from the user.

  When the direct access processing unit 25 is instructed to perform direct access to the DVR 4, the direct access processing unit 25 obtains information such as an address necessary for performing direct access by inquiring of the DAP server 3. The direct access processing unit 25 performs direct access to the DVR 4 based on the acquired information, and instructs the DVR 4 to perform processing according to an instruction from the user.

  FIG. 18 is a block diagram illustrating a configuration example of the DAP server 3. The configuration shown in FIG. 18 is realized by the SOAP server 3-1 and the XMPP server 3-2.

  The controlled device communication unit 31 establishes a constant session by XMPP with the DVR 4 and communicates with the DVR 4. The controlled device communication unit 31 receives the message transmitted from the DVR 4 and outputs the received message to the service server communication unit 33. Further, the controlled device communication unit 31 receives information such as a registration password transmitted from the DVR 4 at the time of initial registration, and outputs the received registration password to the information management unit 32.

  The information management unit 32 manages the storage (registration) of information in the storage unit 3A, and manages the information stored in the storage unit 3A. Information on the control device, information on the controlled device, and the like are managed by the information management unit 32.

  In addition, the information management unit 32 receives a request for information such as an address necessary for direct access from the service server 2-1 and supplies the request via the service server communication unit 33. 31 is controlled to access the DVR 4 to make various settings. The information management unit 32 outputs information, such as an address necessary for performing direct access, acquired by performing various settings to the service server communication unit 33 and causes the service server 2-1 to transmit the information.

Further, the service server communication unit 33 outputs the request to the information management unit 32 when information necessary for direct access is requested from the service server 2-1. The service server communication unit 33, when information necessary for performing direct access is acquired by the information management unit 32 and supplied from the information management unit 32, transmits the information to the service server 2-1.

  FIG. 19 is a block diagram illustrating a configuration example of the DVR 4.

  The control unit 41 controls the overall operation of the DVR 4. For example, when detecting that an event has occurred, the control unit 41 controls the DAP server communication unit 42 to cause the DAP server 3 to transmit a message notifying that. The control unit 41 performs direct access in response to an instruction from the user, and performs processing in response to the user instruction when an action request is transmitted from the service server 2-1.

  The DAP server communication unit 42 establishes a constant session with the DAP server 3 and communicates with the DAP server 3. The DAP server communication unit 42 transmits the message supplied from the control unit 41 to the DAP server 3.

  The direct access receiving unit 43 receives direct access from the service server 2-1, and receives an action request transmitted by direct access. The direct access receiving unit 43 outputs the received action request to the control unit 41.

  As described above, by adding the related information to the information transmitted from the DVR 4 based on the information in the device so that the message is delivered to the user in a form enriched, the user can This makes it possible to accurately determine the recording reservation setting, title deletion, and the like.

  In addition, users are notified of links to official websites of programs and links to websites that sell related products, so users can use the notified information as a trigger to purchase new products such as product purchases and remote recording reservations. Actions can be performed. For example, even if you see a message that contains only information within the range of information managed by DVR4, you can search the Internet to see more related information (related products, related VOD, etc.) Need to do it by themselves, but there is no such need.

  In the above description, the message transmitted from the DVR 4 is transmitted to the service server 2-1 via the DAP server 3, but may be transmitted directly to the service server 2-1. The message directly transmitted to the service server 2-1 is transmitted to the mobile phone 1-1 after being edited in the service server 2-1.

  Here, with reference to the flowchart of FIG. 20, a description will be given of a process in which the DVR 4 as the controlled device directly transmits a message to the service server 2-1 and the service server 2-1 edits the message. To do.

  When an event occurs in step S351, in step S352, the DVR 4 transmits a device authentication request including device authentication information to the SOAP server 3-1.

  In step S361, the SOAP server 3-1 receives the device authentication request and determines whether or not the DVR 4 that has transmitted the device authentication request is a valid device based on the ID included in the device authentication information.

  If it is determined that the DVR 4 is a valid device, in step S362, the SOAP server 3-1 generates a device authentication continuation ID to be assigned to the DVR 4, and transmits the generated device authentication continuation ID and information on its expiration date to the DVR 4. To do.

  In step S353, the DVR 4 receives the information transmitted from the SOAP server 3-1, and stores the device authentication continuation ID and the expiration date information in the storage unit 4A.

  When the device authentication is completed, in step S354, a message requesting acquisition of URI and OTP (One Time Password) is transmitted to the SOAP server 3-1. The message transmitted here includes a device authentication continuation ID, a DAP-ID representing the destination of the message, and a message ID that is the ID of the message itself. The URI is information indicating a transmission destination when the DVR 4 directly transmits a message to the service server 2-1, and the OTP is a password for authenticating the DVR 4.

  In step S363, the SOAP server 3-1 receives the message transmitted from the DVR 4, and in step S364, searches for the URI of the service server 2-1 that represents the transmission destination of the message. In the SOAP server 3-1, for example, the URI of each service server that is a transmission destination of a message from the controlled device is registered at a predetermined timing in association with the DAP-ID.

  In step S365, the SOAP server 3-1 transmits a message requesting acquisition of the URI and OTP to the service server 2-1 based on the URI acquired by the search. The message transmitted here includes the DAP-ID and the message ID which is the ID of the message itself, as well as the DVR 4 number.

  In step S371, the service server 2-1 receives the message transmitted from the SOAP server 3-1.

  In step S372, the service server 2-1 generates an OTP, and stores the generated OTP in association with information included in the message transmitted from the SOAP server 3-1. In addition, the service server 2-1 generates a URI (service server URI) indicating the transmission destination of the message.

  In step S373, the service server 2-1 transmits the generated service server URI and OTP to the SOAP server 3-1.

  In step S366, the SOAP server 3-1 receives the service server URI and OTP transmitted from the service server 2-1, and transmits the service server URI and OTP to the DVR 4 in step S367.

  In step S355, the DVR 4 receives the service server URI and OTP transmitted from the SOAP server 3-1, and in step S356, an event including the OTP is generated for the transmission destination specified by the service server URI. Send a message indicating that

  In step S374, the service server 2-1 receives the message transmitted from the DVR 4, and in step S375, whether or not the OTP included in the message matches the previously generated and stored OTP. To verify. When it is confirmed that the OTP included in the message transmitted from the DVR 4 matches the stored OTP, the service server 2-1 identifies the mobile phone 1-1 as the message transmission destination.

  In step S376, the service server 2-1 edits the message transmitted from the DVR 4 as described with reference to FIGS. 14 and 15, and in step S377, edits the edited message to the mobile phone 1-1. Send to.

  In step S381, the mobile phone 1-1 receives the edited message transmitted from the service server 2-1, and displays it on the display. Thereby, the user can confirm the message edited by the service server 2-1.

  For example, when an operation related to control of the DVR 4 is performed by the user who has confirmed the content of the message, the same processing as the processing described with reference to FIG. 13 is performed.

  As described above, a message notifying that an event has occurred can be directly transmitted from the DVR 4 to the service server 2-1.

  In the above, when a recommended program is selected, when there is a new title, when it is detected that there is a reservation that cannot be recorded, when there is a title to be deleted, it is detected that there is not enough free space on the hard disk When a failure occurs, a message notifying that an event has occurred is transmitted from the DVR 4. However, the event that triggers the transmission of the message is not limited to these.

  For example, when recording is being executed according to a reservation set by the user of the mobile phone 1-1, when an instruction to stop recording is given by another user near the DVR 4, it is recognized that an event has occurred. Then, a message notifying that the stop of the recording being executed is instructed may be transmitted to the mobile phone 1-1. The message transmitted here is also appropriately edited in the service server 2-1.

  FIG. 21 is a diagram illustrating an example of message transmission.

  When recording is stopped by another user while recording is being executed in accordance with the reservation set by the user of the mobile phone 1-1, the DVR 4 is indicated by an arrow # 1 in FIG. A message is transmitted to the DAP server 3.

  Further, as indicated by arrow # 2, the DVR 4 interrupts processing according to an instruction from another user. That is, even when the stop of recording is instructed, at this stage, recording is continued without being stopped.

  The message transmitted from the DVR 4 is transmitted from the DAP server 3 to the service server 2-1 designated as the transmission destination, as indicated by arrow # 3.

  The service server 2-1 that has received the message transmitted from the DAP server 3 edits the message as indicated by arrow # 4. For example, when the content of the message transmitted from the DVR 4 simply indicates that the stop of recording is instructed, the service server 2-1 determines whether or not to permit the stop of recording. The message is edited by adding information of buttons operated when one user selects.

  The service server 2-1 transmits the edited message to the mobile phone 1-1 as the control device as indicated by arrow # 5.

  As indicated by arrow # 6, the mobile phone 1-1 displays the edited message transmitted from the service server 2-1, and notifies the user of the content of the message.

  The user can select whether or not to stop recording by pressing a button displayed on the display of the mobile phone 1-1 based on the information added by the service server 2-1.

  For example, when it is selected not to allow the stop of the recording, as indicated by an arrow # 7, the cellular phone 1-1 requests the service server 2-1 to perform a process corresponding thereto.

  The service server 2-1 records information on the action requested from the mobile phone 1-1 as indicated by an arrow # 8 as a history, and after recording the history, the service server 2-1 indicates a DVR 4 as indicated by an arrow # 9. Is directly accessed, and the execution of the action selected by the user is instructed.

  The DVR 4 that has received the request from the service server 2-1 performs processing according to the requested action as indicated by arrow # 10. That is, when the user selects not to permit the stop of recording, the DVR 4 continues without stopping the recording.

  Thus, even when another user instructs to stop the recording that is being performed, the recording is not stopped until the user of the cellular phone device 1-1 that has set the recording reservation has permission. In other words, it is possible to prevent the recording from being stopped arbitrarily without the knowledge of the user of the cellular phone device 1-1 who has set the recording reservation.

  FIG. 22 is a diagram illustrating a message transmitted from the DVR 4 in the case of performing the above-described process and a process of the service server 2-1 that has received the message. When the stop of the recording that is being executed according to the reservation is instructed, a message notifying that is transmitted from the DVR 4, and the service server 2-1 that has received the message is permitted to stop by the user of the mobile phone 1-1. Until DVR4 is released, let DVR4 continue recording.

  The series of processes described above can be executed by hardware or can be executed by software. When a series of processing is executed by software, a program constituting the software executes various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a program recording medium in a general-purpose personal computer or the like.

  FIG. 23 is a block diagram illustrating a hardware configuration example of a computer that executes the above-described series of processing by a program.

  A CPU 101, a ROM (Read Only Memory) 102, and a RAM (Random Access Memory) 103 are connected to each other by a bus 104.

  An input / output interface 105 is further connected to the bus 104. The input / output interface 105 includes an input unit 106 including a keyboard, a mouse, and a microphone, an output unit 107 including a display and a speaker, a storage unit 108 including a hard disk and a non-volatile memory, and a communication unit 109 including a network interface.
