  ADVANTAGE OF THE INVENTION According to this invention, the control method which controls the output of the image | video displayed on PC etc., and a control apparatus using the same are realizable.

  Before specifically describing the embodiment of the present invention, an outline of the embodiment of the present invention will be described first. A display control system according to an embodiment of the present invention includes an output device and a display control device installed in a house, and a VoD server installed outside the house.

  The user accesses the VoD server via the display control device, and outputs viewing data desired to view to the output device by downloading or streaming. However, the viewing data provided by the VoD service may include a video that should not be viewed by a specific user, for example, a video related to R18 designation that prohibits viewing by a user under 18 years old. It is preferable to limit the output of such images.

  Therefore, in the present embodiment, when the user who is the owner of the terminal device exists in the house, specifically, when the user is at home or when the user is in the vicinity of the house, the display control device The above-mentioned problem is solved by limiting the output devices for viewing data that should not be viewed by the user. Details will be described later.

  First, an FMC (Fixed / Mobile Convergence) communication system applied to the display control system of the present embodiment will be described. The FMC communication system is a combination of communication by a wired line (Fixed) via a server fixedly installed in a home or the like and mobile communication that can execute communication while moving outdoors (Convergence). Communication system.

  FIGS. 1A and 1B show first and second examples of the FMC communication system 400 applied to the embodiment of the present invention. 1A and 1B, an FMC communication system 400 is represented by a wireless LAN base station device 80, a mobile communication network 52 represented by a network 50, a fixed communication network 54, and a wireless terminal device 20. A first wireless terminal device 20a, a second wireless terminal device 20b, a first mobile communication base station device 70a represented by a mobile communication base station device 70, and a second mobile communication base station device 70b are included. The wireless terminal device 20 includes a mobile wireless antenna 92 for performing mobile communication with the mobile communication base station device 70, and a wireless LAN antenna 94 for performing communication with the wireless LAN base station device 80 via a wireless LAN. Have The FMC communication system 400 may include a control server (not shown) between the mobile communication network 52 and the fixed communication network 54.

  The mobile communication base station device 70 and the wireless LAN base station device 80 perform wireless communication with the wireless terminal device 20 existing in each communication area. In FIG. 1A, the first mobile communication base station apparatus 70a performs mobile communication with the first radio terminal apparatus 20a existing in the first communication area 410 indicated by the broken line, and performs the second mobile communication. The communication base station device 70b performs mobile communication with the second wireless terminal device 20b existing in the second communication area 420 indicated by a broken line. The first communication area 410 and the second communication area 420 may be outdoor communication areas. Moreover, the 1st communication area 410 and the 2nd communication area 420 are communication areas which have a wider range than the 3rd communication area 430 mentioned later.

  For example, when communication is performed between the first wireless terminal device 20a and the second wireless terminal device 20b, the first wireless terminal device 20a first performs wireless communication with the first mobile communication base station device 70a. Execute. Next, the first mobile communication base station device 70 a performs wired communication with the second mobile communication base station device 70 b via the network 50. Further, the second mobile communication base station device 70b performs wireless communication with the second wireless terminal device 20b, thereby communicating between the first wireless terminal device 20a and the second wireless terminal device 20b. Is possible. Note that the wireless communication between the wireless terminal device 20 and the mobile communication base station device 70 in FIG. 1 (a) may be performed by a known mobile communication method such as a CDMA (Code Division Multiple Access) communication. Good.

  FIG. 1B shows a case where the second wireless terminal device 20 b existing in the second communication area 420 in FIG. 1A moves into the third communication area 430. The third communication area 430 is a communication area centered on a residence where the wireless LAN base station device 80 is installed, and is an area where wireless communication by wireless LAN is possible. In FIG.1 (b), when performing communication between the 1st radio | wireless terminal apparatus 20a and the 2nd radio | wireless terminal apparatus 20b, the 1st radio | wireless terminal apparatus 20a is the 1st mobile communication base station apparatus 70a first. Wireless communication is performed with Next, the first mobile communication base station device 70 a performs wired communication with the wireless LAN base station device 80 via the mobile communication network 52 and the fixed communication network 54.

  Here, the wireless LAN base station device 80 executes a wireless communication method different from the wireless communication method between the wireless terminal device 20 and the mobile communication base station device 70 with the second wireless terminal device 20b. The communication between the first wireless terminal device 20a and the second wireless terminal device 20b is made possible. Note that the “different wireless communication method” includes a communication method such as a wireless LAN method, and may be a short-range wireless communication method in which a communication area is smaller than that of mobile communication. Here, a case of communication by the wireless LAN method will be described. In this case, the wireless LAN base station device 80 recognizes the second wireless terminal device 20b as a terminal device in a short-range wireless communication method such as a wireless LAN method, and thereby transmits a signal transmitted via the network 50 to the second. It can be relayed to the wireless terminal device 20b.

  The relay process is executed in the following order. First, when the second wireless terminal device 20b moves to the third communication area 430 of the wireless LAN base station device 80, the identification information of the second wireless terminal device 20b is registered in the wireless LAN base station device 80. Next, the wireless LAN base station device 80 registers the identification information related to the second wireless terminal device 20b in a control server (not shown). Here, when there is a communication request to the second wireless terminal device 20b, the control server sets the communication route to a route via the wireless LAN base station device 80. By such processing, the second wireless terminal device 20b can execute communication by the wireless LAN method via the wireless LAN base station device 80. The second wireless terminal device 20b may register the identification information in the control server instead of the wireless LAN base station device 80.

  In general, compared to a normal mobile communication system, a short-range wireless communication system often has a stable communication environment, and therefore has good communication quality and a high transmission rate. Therefore, according to such an aspect, the wireless terminal device 20 can execute communication in any communication area, and can execute communication in a more preferable communication environment. In addition, the wireless terminal device 20 can perform communication by a plurality of wireless communication methods using a single telephone number, thereby providing a flexible communication environment to the user.

  FIG. 2 is a diagram illustrating a configuration example of the first display control system 100 according to the embodiment of the present invention. The first display control system 100 includes a display control device 10, a wireless LAN base station device 80, a first wireless terminal device 20a and a second wireless terminal device 20b represented by the wireless terminal device 20, a display device 30, A VoD server 40 and a network 50 are included.

  The display control device 10 and the wireless LAN base station device 80 are fixedly installed at predetermined locations. Here, “fixed installation” includes installation at different positions on the same premises. As described above, the wireless LAN base station device 80 can perform wireless communication with the wireless terminal device 20 when the wireless terminal device 20 exists in the vicinity of the place where the wireless LAN base station device 80 is installed. The communication here may be a wireless LAN system defined by IEEE 802.11 or the like, or may be other short-range wireless communication.

  The display control device 10 accesses the VoD server 40 installed at a location different from the location where the display control device 10 is installed via the wireless LAN base station device 80 and the network 50, and acquires viewing data. Further, the display control device 10 outputs the viewing data acquired from the VoD server 40 to the display device 30 to the display device 30. Here, the network 50 may be a public or a dedicated network. Further, when accessing the VoD server 40, the display control device 10 may perform wireless communication with the wireless LAN base station device 80 or may perform wired communication. For convenience of explanation, only the first wireless terminal device 20a and the second wireless terminal device 20b are shown, but other wireless terminal devices 20 may exist.

  The display control device 10 is a wireless terminal device under its control and a wireless terminal device 20 of another user according to a predetermined user's operation, and the wireless terminal device to be accommodated in the wireless LAN base station device 80 20 identification information is registered. The user to be registered is a user who has an address or residence in the premises where the display control device 10 is installed. For example, in the home, when registering in the display control device 10 installed at home, the registered user includes a family including parents and children, and other users living with the family. May be included.

  Next, the display control device 10 acquires viewing data that can be viewed from the VoD server 40 via the wireless LAN base station device 80 and the network 50 according to an instruction from the user. Further, the display control device 10 displays the acquired list of viewing data on the display device 30. Based on the list displayed on the display device 30, the user registers a viewing allowance flag indicating whether or not to allow other users to view for each acquired viewing data.

  Further, the display control device 10 manages the user's entry / exit based on the identification information of the user's already registered wireless terminal device 20. Specifically, when the user who has gone out returns home with the wireless terminal device 20 owned by the user at the installation location of the wireless terminal device 20, for example, at home, the wireless terminal device 20 is Wireless communication with the station device 80 by wireless LAN is possible. When wireless communication becomes possible, the display control device 10 acquires the identification information of the wireless terminal device 20 via the wireless LAN base station device 80, and determines whether or not it matches the already registered identification information. Collate. If they match, the user is registered as a user who has returned home. This collation may be performed when the wireless terminal device 20 performs communication with the wireless LAN base station device 80.

  FIG. 3 is a diagram illustrating a configuration example of the display control apparatus 10 of FIG. The display control device 10 includes an authentication unit 14, a registration unit 16, a communication unit 18, a storage unit 22, an operation unit 24, and an output control unit 28.

  The operation unit 24 gives an instruction to the registration unit 16, the request unit 26, or the output control unit 28 according to a user operation. The user's operation may be executed by pressing a button arranged on a controller (not shown) or a keyboard of a PC connected to the display control device 10, or may be executed by voice recognition.

  First, in an initial state, a predetermined user, for example, a parent who manages a child, registers a terminal device under his / her control and identification information of another user, for example, a terminal device owned by the child. . Specifically, the operation unit 24 notifies the registration unit 16 of identification information related to registration, and the registration unit 16 registers the notified identification information in the storage unit 22. Next, the predetermined user acquires viewing data from the VoD server 40. Only a list of viewing data may be acquired. In this acquisition process, the management user operates the operation unit 24 to give an instruction to acquire desired viewing data, and the operation unit 24 sends the instruction to the communication unit 18 via the request unit 26 according to the instruction. Just tell.

  The communication unit 18 is an interface with the wireless LAN base station device 80. The communication unit 18 accesses the VoD server 40 via the wireless LAN base station device 80 and makes a transmission request for viewing data. If the viewing data exists in the VoD server 40 and is set so that the requested user can view, the communication unit 18 can acquire the viewing data from the VoD server 40. The acquired viewing data is sent to the registration unit 16. Further, the fact that it has been acquired is displayed on the display device 30 via the output control unit 28.

  The user who has confirmed that the data has been acquired operates the operation unit 24 to register a flag indicating whether or not the viewing data may be viewed for each user already registered in the storage unit 22. 16 is registered. This registration process may be executed every time viewing data is acquired, or may be executed collectively. The registration process is also executed when a new user is registered in the storage unit 22. The number of flags indicating whether or not the user should be allowed to view is represented by the product of the total number of users and the total number of viewing data. For this reason, for example, when two viewing data are acquired and three users are registered in the display control device 10, the user needs to set six flags. A specific example will be described later.

  When the viewing data does not exist in the VoD server 40 or when the viewing data is not set to be viewable by the requested user, the communication unit 18 receives a signal indicating that and displays it. The device 30 does not display the viewing data on the VoD server 40, or outputs a display indicating that the viewing data cannot be viewed.

  A wireless LAN base station device 80 (not shown) performs wireless communication with the wireless terminal device 20 existing in the vicinity of the place where the display control device 10 is installed. In addition, the wireless LAN base station device 80 acquires the identification information from the wireless terminal device 20 that is performing wireless communication, and sends the acquired identification information to the authentication unit 14 via the communication unit 18. Next, the authentication unit 14 accesses the storage unit 22 to determine whether or not the identification information transmitted from the wireless LAN base station device 80 is registered in the storage unit 22, and the result is registered in the registration unit 16. Notify

  When the registration unit 16 is notified that the identification information is registered in the storage unit 22, the registration unit 16 determines that the user having the wireless terminal device 20 corresponding to the identification information has come home, and the flag corresponding to the identification information Set to "Home". When the registration unit 16 is notified that the identification information is not registered in the storage unit 22, the registration unit 16 may transmit a signal to the wireless terminal device 20 to refuse communication.

  The communication unit 18 periodically acquires identification information with the wireless terminal device 20 authenticated by the authentication unit 14 and executes the same authentication process as described above. Here, when the wireless terminal device 20 of the user who is registered as “at home” cannot be recognized continuously for a predetermined number of times or more, the display control device 10 determines that the user has gone out, and the display control device 10 As a user who is out, the flag is set to “out”.

  Here, when viewing data is displayed on the display device 30 by the user, only viewing data registered as viewable can be displayed for all of the users who are registered as “at home” in the storage unit 22. On the other hand, when viewing data of any one user is registered as not viewable, the user cannot cause the display device 30 to output the viewing data. Specifically, a list including all viewing data is displayed on the display device 30, and viewing data for which viewing is restricted is set so that the user cannot select it. Note that the selection by the user may be restricted by displaying a list of viewing data on the display device 30 and removing viewing data registered as unviewable from the list. Therefore, the viewing data is not output to the display device 30 unless the user goes out or changes the contents of registration.

  This will be described using an example. FIGS. 4A to 4D are diagrams showing first and second registration examples in the storage unit 22 of FIG. 3 and first and second display examples in the display device 30. FIG. As illustrated in FIGS. 4A and 4C, the first and second registration examples include an ID column 500 indicating “ID of the wireless terminal device 20” and “information indicating availability of viewing for each viewing data”. And a home flag column 520 indicating “information indicating home / outing”. Here, four IDs are registered as the ID column 500. Further, N pieces of viewing data are registered, and for each ID, “O” is displayed in the viewing flag column 510 as “information indicating availability of viewing for each viewing data”, and “×” when viewing is impossible. Is registered. For each ID, “information indicating home / outing” is registered as “at home” or “outing”. If distance information is obtained during communication between the wireless LAN base station device 80 and the wireless terminal device 20, it indicates that the wireless terminal device 20 is close enough to view the FMC communication system 400 in addition to the home flag. An in-room flag representing “in-room” may be added.

  In the first registration example shown in FIG. 4A, “A” and “B” in the ID column 500 are registered as “◯” in the viewing flag column 510 for all the viewing data, In the home flag column 520, “at home” is registered. On the other hand, when the ID column 500 is “C”, the viewing data No. 2 and No. 3, the viewing flag column 510 is registered as “×”. 1 and No. For N, “O” is registered in the viewing flag column 510. The home flag column 520 is registered as “going out”. Note that “◯” registered in the viewing flag column 510 indicates that the corresponding user can view the viewing data, and “x” indicates that viewing cannot be performed. .

  Further, when the ID column 500 is “D”, the viewing data No. 2 and No. For N, the viewing flag column 510 is registered as “×”. Also, the home flag column 520 whose ID column 500 is “D” is registered as “at home”. For convenience of explanation, here, viewing data No. 4-No. As for (N-1), “×” is registered in the viewing flag column 510 for any ID.

  In the state of the first registration example shown in FIG. 4A, there are three users “A”, “B”, and “D” registered as “at home” in the home flag column 520. Here, among the three persons, “×” is registered in the viewing flag column 510 because the viewing data No. for the user “D” is registered. 2 and No. N viewing data. Therefore, in this state, even if the user associated with “A” and “B” is viewing data No. 2 or No. Even when N is desired to be viewed, these are viewing data that is not preferable for “D”, and “x” is registered in the viewing flag column 510 in advance, so that it is not output to the display device 30. Therefore, the user displays No. 1 on display device 30. 1 or No. Any one of the viewing data of 3 can be output. When the occupancy flag can be used, it may be determined whether or not “in-room” is used instead of “at-home”.

  FIG. 4B is a diagram showing a first display example of the display device 30 in the first registration example of FIG. The first display example includes “viewing data No.” and “viewing data name” for each viewing data. As described above, the viewing data that can be viewed in the case of the first registration example of FIG. 1 or No. As shown in the figure, as viewing data that can be viewed on the display device 30, as shown in FIG. 1 and No. 3 will be displayed.

  In the second registration example shown in FIG. 4C, “at home” is registered in the home flag column 520 of “C” in the ID column 500, compared to the first registration example shown in FIG. Is different. This indicates that the user who owns the wireless terminal device 20 related to “C” has returned home.

  In the state of the second registration example shown in FIG. 4C, all the users who are registered as “at home” in the home flag column 520 are all. Therefore, unlike the first registration example, each flag shown in the viewing flag column 510 for all members is considered. Therefore, in this state, the viewing data No. No. 1 was viewable, and No. 1 was viewable in the first registration example. Other viewing data including 3 cannot be viewed. According to such an aspect, since the restriction content of the output viewing data is changed according to the members who are at home including the user who has returned home, it is possible to prevent undesirable viewing data from being erroneously output.

  FIG. 4D is a diagram showing a second display example of the display device 30 in the second registration example of FIG. Similar to the first display example, the second display example includes “viewing data No.” and “viewing data name” for each viewing data. As described above, the viewing data that can be viewed in the case of the second registration example of FIG. No. 1 as viewing data, as shown in FIG. Only 1 will be displayed. Note that the first and second display examples illustrated in FIGS. 4B and 4D may be displayed on the display of the wireless terminal device 20.

  These configurations described above can be realized in hardware by a CPU, memory, or other LSI of an arbitrary computer, and in terms of software, it is realized by a program loaded in the memory. Describes functional blocks realized through collaboration. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  Next, the operation of the display control device 10 in FIG. 2 will be described. FIG. 5 is a flowchart showing an operation example of the display control apparatus 10 of FIG. This process may be executed periodically or may be executed by the user's specification. Prior to this process, it is assumed that registration of identification information for each user and information regarding whether or not viewing data can be viewed are registered by the management user.

  First, the display control apparatus 10 accesses the storage unit 22, selects predetermined viewing data, and determines whether the viewing data is viewable (S10). Here, when any one of the users who are “at home” cannot view the viewing data (N in S10), the display control device 10 restricts the output of the viewing data (S12). ). On the other hand, when all the users who are “at home” can view the viewing data (Y in S10), the display control device 10 determines whether there is other viewing data to be determined. Is confirmed (S14). If there is other viewing data to be determined (Y in S14), the process returns to S10. On the other hand, when all the viewing data has been determined (N in S14), the display control device 10 displays a list of limited viewing data on the display device 30 based on the already determined result (S16). .

  FIG. 6 is a sequence diagram illustrating an operation example of the first display control system 100 of FIG. First, the user registers the identification number for the wireless terminal device 20 of the user to be registered as initial registration with the display control device 10 (S100). Next, the user requests viewing data from the VoD server 40 via the wireless LAN base station device 80 (S102, S104). The VoD server 40 transmits the viewing data according to the request to the display control apparatus 10 via the wireless LAN base station apparatus 80 (S106, S108). Here, the user determines whether or not the received viewing data can be viewed for each user registered in the process of S100, and registers a flag in the display control apparatus 10 (S110).

  Here, when the user who owns the first wireless terminal device 20a returns home (S112), the first wireless terminal device 20a sends its identification information to the display control device 10 via the wireless LAN base station device 80. Transmit (S114, S116). Next, the display control apparatus 10 determines whether or not the received identification information matches the identification information registered in S100. If the identification information matches, the display control apparatus 10 authenticates the first wireless terminal device 20a (S118) and performs communication. to approve. Furthermore, the display control apparatus 10 checks the flag registered by the process of S110 and determines whether or not the viewing data acquired by the process of S108 or the like can be viewed by the user related to the first wireless terminal apparatus 20a. (S120). If it is determined that the user associated with the first wireless terminal device 20a may view, the output process is performed on the display device 30 (S122).

  Next, when the user who owns the second wireless terminal device 20b returns home (S124), the same processing as S114 to S120 is executed (S126 to S132). Here, when it is determined that the viewing data already displayed on the display device 30 should not be viewed by the user of the second wireless terminal device 20b, an output restriction process is performed on the display device 30 (S134). .

  According to the above-described aspect, by outputting the viewing data to the output device in accordance with the output permission information corresponding to the acquired identification information, it is possible to limit the output of the video that should not be viewed by a specific user. In addition, by causing the output device to output the viewing data selected according to the output permission information associated with each of the newly registered new identification information and the already registered identification information, the viewing data is newly returned home. Even if the video should not be viewed by the user, the output can be limited.

  Next, the modification of embodiment of this invention is shown. In addition, about the part which is common in embodiment mentioned above, the same code | symbol is attached | subjected and description is simplified. First, an outline will be described. This modification relates to the second display control system 200. The second display control system 200 has the same configuration as the first display control system 100 shown in FIG.

  In the second display control system 200, first, the wireless terminal device 20 presupposes that predetermined viewing data downloaded from a VoD server is stored in advance, and the user displays the viewing data on the display device 30. Is assumed. The request process may be executed by the user operating the display control device 10, or may be executed by operating the wireless terminal device 20.

  In general, when data stored in the wireless terminal device 20 is output to a large display device such as a television receiver, the data transfer speed is slow and the image quality is often deteriorated. It is desirable to do. Therefore, in the present modification, the display control device 10 first inquires of the VoD server 40 as to whether or not the requested viewing data can be viewed. If there is a reply from the VoD server 40 that viewing is not possible, the display control device 10 acquires viewing data from the wireless terminal device 20 and outputs the viewing data to the display device 30. On the other hand, when there is a reply that viewing is possible from the VoD server 40, the display device 30 acquires the viewing data from the VoD server 40 and outputs it to the display device 30.

  As described above, when the viewing data to be displayed also exists in the VoD server 40, the viewing data stored in the VoD server 40 is prioritized instead of acquiring the viewing data stored in the wireless terminal device 20. With such an aspect, by acquiring viewing data from the VoD server 40 preferentially instead of the wireless terminal device 20, the transfer speed and quality of the output viewing data can be further improved.

  FIG. 7 is a diagram illustrating a configuration example of the display control apparatus 10 according to a modification of the embodiment of the present invention. FIG. 7 includes a communication unit 18, an operation unit 24, an output control unit 28, and an inquiry unit 32. For convenience of explanation, in FIG. 7, the authentication unit 14, the registration unit 16, the storage unit 22, and the request unit 26 are omitted from the configuration illustrated in FIG. 3, but these are the second display control system 200. May be included. Hereinafter, a case where the user operates the wireless terminal device 20 in order to output predetermined viewing data to the display device 30 will be described. In this case, first, a request signal is transmitted from the wireless terminal device 20 to the display control device 10.

  The communication unit 18 receives a request signal for predetermined viewing data transmitted from the wireless terminal device 20 via a wireless LAN base station device 80 (not shown). The received request signal is transmitted to the inquiry unit 32. The inquiry unit 32 causes the VoD server 40 to transmit an inquiry signal to the communication unit 18 regarding the viewing data related to the request signal. Here, the inquiry signal is a signal indicating whether or not the desired viewing data stored in the VoD server 40 can be viewed. “Whether or not viewing is possible” includes “whether or not desired viewing data is stored in the VoD server 40” and includes “whether or not the requested user has authority to view”.

  Next, the inquiry unit 32 obtains an answer from the VoD server 40 via the wireless LAN base station device 80 and the communication unit 18. Here, when the answer indicates “viewing is possible”, the inquiry unit 32 acquires viewing data from the VoD server 40 and sends it to the output control unit 28. The output control unit 28 causes the display device 30 to display the transmitted viewing data. On the other hand, when the answer indicates “unviewable”, the inquiry unit 32 instructs the wireless LAN base station device 80 to acquire viewing data from the wireless terminal device 20 via the communication unit 18. The wireless LAN base station device 80 transmits a request signal for viewing data to the wireless terminal device 20. Further, the wireless LAN base station device 80 receives the viewing data transmitted from the wireless terminal device 20 and sends it to the output control unit 28. The output control unit 28 causes the display device 30 to display the transmitted viewing data.

  Next, the operation of the display control apparatus 10 according to the second display control system 200 of the present modification will be described. FIG. 8 is a flowchart showing an operation example of the display control apparatus 10 according to the modification of the embodiment of the present invention. This process may be started when a predetermined viewing data is selected by the user operating the wireless terminal device 20 or the display control device 10.

  The display control apparatus 10 inquires of the VoD server 40 as to whether or not the requested viewing data can be viewed (S20). When the answer from the VoD server 40 indicates “viewable” (Y in S22), the display control apparatus 10 acquires the viewing data from the VoD server 40 (S24). On the other hand, when the answer from the VoD server 40 indicates “unviewable” (N in S22), the display control device 10 acquires the viewing data from the wireless terminal device 20 (S26). Further, the display control device 10 outputs the acquired viewing data to the display device 30 (S28).

  FIG. 9 is a sequence diagram showing an operation example of the second display control system 200 according to the modification of the embodiment of the present invention. First, when the user operates the wireless terminal device 20 downloaded from the VoD server 40, the wireless terminal device 20 sends a request signal for outputting the viewing data to the display device 30 to the wireless LAN base station device 80. To the display control device 10 (S200, S202). Next, the display control apparatus 10 inquires of the VoD server 40 via the wireless LAN base station apparatus 80 whether or not the viewing data requested can be viewed (S204, S206).

  The VoD server 40 determines whether or not the user can view the requested viewing data. If viewing is possible, the VoD server 40 replies to that effect via the wireless LAN base station device 80 (S208, S210). In this case, the display control device 10 requests the viewing data, which is answered that viewing is possible, from the VoD server 40 via the wireless LAN base station device 80 (S212, S214). The VoD server 40 transmits the requested viewing data via the wireless LAN base station device 80 (S216, S218). The display control device 10 outputs the transmitted viewing data to the display device 30 (S220).

  By taking the above-mentioned mode, when there is a reply that the desired viewing data can be output from the server, high-speed output processing is realized by preferentially acquiring the viewing data from the server and outputting it to the output device In addition, the quality of the output viewing data can be improved. On the other hand, when there is a reply that the desired viewing data cannot be output from the server, the viewing data can be acquired from the wireless terminal device 20 and output to the output device. Thus, the flexibility of the system can be improved by switching the output source device according to the situation.

  Next, another modification of the embodiment of the present invention will be shown. In addition, about the part which is common in embodiment mentioned above, the same code | symbol is attached | subjected and description is simplified. First, an outline will be described. This modification relates to the third display control system 300. FIG. 10 is a diagram illustrating a configuration example of the third display control system 300 according to another modification of the embodiment of the present invention. The third display control system 300 further includes a current location acquisition device 60 and a third wireless terminal device 20c as compared to the configuration of the first display control system 100 shown in FIG. Here, the current location acquisition device 60 includes a configuration and a function as a base station device that can execute mobile communication with the third wireless terminal device 20c.

  Here, the 3rd radio | wireless terminal apparatus 20c includes the structure and function which perform communication with a GPS communication satellite, and acquire the information regarding a present location. The information regarding the current location includes so-called navigation messages received from a plurality of GPS communication satellites. The third wireless terminal device 20c notifies the current location acquisition device 60 of the acquired navigation message, and estimates the current location of the third wireless terminal device 20c based on the navigation message notified by the current location acquisition device 60. Further, the display control apparatus 10 in the present modification may have a configuration similar to that shown in FIG. Hereinafter, this modification will be described with reference to FIGS. 10 and 3.

  Generally, in a display system that displays the current location of a wireless terminal device, a user who confirms the current location grasps the current location of the wireless terminal device of a predetermined user by operating a PC or the like. However, since the present location that can be confirmed is the current location to the last, it could not be confirmed until the location changed over time. For example, when the user whose current location is confirmed is a child, a parent who confirms the location of the child needs to operate the PC regularly.

  Therefore, in the present embodiment, when a user whose current location is to be confirmed exists in the home and a user whose current location is to be confirmed does not exist in the home, the control device is owned by the user whose current location is to be confirmed. By regularly acquiring the current location of the wireless terminal device, the current location of the user is displayed on the display screen or the like.

  First, the display control apparatus 10 according to the present modification executes entry / exit management by registering / deleting identification information for each user and “information indicating home / outing” as in the above-described embodiment. In addition, the display control device 10 also manages a flag indicating “whether or not the user should check the current location” for each user. This flag is set by the management user. In the above state, the output control unit 28 first accesses the storage unit 22 and confirms the user registered as “going out”.

  Here, when the user registered as “going out” is “a user who should confirm the current location”, the output control unit 28 acquires the current location via the communication unit 18 and the wireless LAN base station device 80. The communication unit 18 accesses the current location acquisition device 60 to cause the third wireless terminal device 20c to acquire the current location. For example, when the “user who should confirm the current location” is the third wireless terminal device 20c shown in FIG. 10, the third wireless terminal device 20c acquires information on the current location from the GPS communication satellite, and uses the information as the current location acquisition device. Tell 60. The current location acquisition device 60 estimates the current location of the third wireless terminal device 20c based on the transmitted information on the current location, and notifies the display control device 10 of the estimated result via the wireless LAN base station device 80. . Note that the communication unit may access the third wireless terminal device 20c and notify the current location information obtained by the third wireless terminal device 20c through the exchange with the current location acquisition device 60.

  Next, the communication unit 18 notifies the output control unit 28 of information relating to the current location acquired from the current location acquisition device 60. The output control unit 28 displays the notified information on the current location on the display device 30. Further, when displaying the current location, the output control unit 28 may display the current location in association with the name of the user who has the current location, for example, the name of the user who owns the third wireless terminal device 20c. Even when there are a plurality of “users whose current location is to be confirmed”, the display control device 10 acquires the current location in the same manner as described above, and displays the current location for each user on the display device 30. The acquisition of the current location may be started by a user instruction or may be periodically executed. Thereby, the user who manages the user of the 3rd radio | wireless terminal apparatus 20c can recognize the location of the user of the 3rd radio | wireless terminal apparatus 20c regularly regularly.

  This will be described using a specific example. FIG. 11 is a diagram illustrating a memory registration example in the display control apparatus 10 of FIG. As illustrated, the registration example includes an ID column 500 indicating “ID of the wireless terminal device 20”, a current location display flag column 530 indicating “present location display flag”, and a home flag column indicating “information indicating home / outing”. 520. Here, four IDs are registered in the ID column 500. For each ID, a flag indicating “at home” or “going out” is registered in the home flag column 520.

  Here, in the current position display flag column 530, “unnecessary” is registered for “A” and “B” shown in the ID column 500, and “necessary” is registered for “C” and “D”. In the home flag column 520, “at home” is registered for “A” and “D” shown in the ID column 500, and “going out” is registered for “B” and “C”. In the case of the registration example as described above, the user who is registered as “going out” in the home flag column 520 and registered as “necessary” in the current location display flag column 530 is the user of the wireless terminal device 20 related to “C”. Become the owner. Therefore, the display control device 10 acquires the current location of the wireless terminal device 20 of the user C and displays the current location on the display device 30.

  Next, the operation of the display control apparatus 10 according to the third display control system 300 of this modification will be described. FIG. 12 is a flowchart showing an operation example of the display control apparatus 10 according to another modification of the embodiment of the present invention. This process may be executed by the user's specification or may be executed periodically.

  The display control apparatus 10 accesses the storage unit 22, selects a predetermined user, and determines whether or not the user is out (S30). Here, when the predetermined user is “going out” (Y in S30), the display control apparatus 10 checks the “current location display flag” of the predetermined user (S32). Here, when the “current location display flag” indicates “necessary” (Y in S32), the display control device 10 acquires the current location of the user from the current location acquisition device 60 (S34). Further, the display control device 10 outputs the acquired current location to the display device 30 (S36), and proceeds to the processing of S38. On the other hand, when the predetermined user is “at home” (N in S30) or when the “current location display flag” indicates “unnecessary” (N in S32), the process proceeds to S38. If there is another user to be determined (N in S38), the process returns to S30. On the other hand, if there is no other user to be determined (Y in S38), the process ends.

  FIG. 13 is a sequence diagram showing an operation example of the third display control system 300 according to another modification of the embodiment of the present invention. In the following, it is assumed that each user carrying the first wireless terminal device 20a and the second wireless terminal device 20b is registered as “at home”. First, the wireless LAN base station device 80 periodically performs communication between the first wireless terminal device 20a and the second wireless terminal device 20b (S301, S302). Here, it is assumed that the user carrying the second wireless terminal device 20b has gone out (S303). Then, as shown in the figure, even if the wireless LAN base station device 80 transmits a signal for confirming its existence to the second wireless terminal device 20b (S304), there is no response from the second wireless terminal device 20b. . Here, when there is no response continuously for a predetermined number of times or more, it is determined that the user carrying the second wireless terminal device 20b has gone out, and the wireless LAN base station device 80 notifies the display control device 10 to that effect. Is transmitted (S305). The display control apparatus 10 registers the home flag as “going out” with the user carrying the second wireless terminal device 20b as a user who is out (S306). Next, the display control device 10 determines whether or not the current location display flag corresponding to the identification information is registered as “necessary” for the second wireless terminal device 20b whose home flag is registered as “going out” ( S308).

  Here, for the identification information of the second wireless terminal device 20b, when the corresponding current location display flag is registered as “necessary”, the display control device 10 transmits the current location acquisition device 60 via the wireless LAN base station device 80. In response to this, a request signal for obtaining the current location of the second wireless terminal device 20b is transmitted (S310, S312). The current location acquisition device 60 transmits a request signal to the effect that the information on the current location is transmitted to the second wireless terminal device 20b when the request signal is received (S314). The second wireless terminal device 20b receives the request signal and executes GPS satellite communication and communication to acquire information on the current location (S316). Further, the second wireless terminal device 20b earns and transmits information on the current location to the current location acquisition device 60 (S318).

  The current location acquisition device 60 estimates the current location of the second wireless terminal device 20b based on the information on the current location received from the second wireless terminal device 20b (S320). Further, the current location acquisition device 60 transmits the estimated current location of the second wireless terminal device 20b to the display control device 10 via the wireless LAN base station device 80 (S322, S324). The display control device 10 outputs the acquired current location of the second wireless terminal device 20b to the display device 30 (S326).

  By taking the above-described aspect, when the wireless terminal device 20 from which identification information has not been acquired is the wireless terminal device 20 that should output the current location to the display device 30, the current location of the wireless terminal device 20 is acquired and acquired. The user can flexibly recognize the current location of the wireless terminal device 20 by causing the display device 30 to output the current location in correspondence with the display indicating the wireless terminal device 20. Further, by displaying the current location of the wireless terminal device 20 acquired periodically, the user can grasp the current location nearest to the user who owns the wireless terminal device 20 one by one. Further, since the current location of the user who owns the wireless terminal device 20 is displayed without the user's operation, the convenience of the user can be improved, and the security of the user who owns the wireless terminal device 20 can be enhanced. .

  The viewing data has been described as being acquired in advance. However, the present invention is not limited to this. First, the display control apparatus 10 acquires a list of viewing data, and viewing for each user registered in the display control apparatus 10 based on the list. The viewing data to be acquired may be selected based on the availability flag, and only the selected viewing data may be acquired from the VoD server 40. Moreover, this acquisition process may be performed by streaming. Thereby, communication cost can be reduced. Needless to say, the same effects as described above can be obtained.

  It has been described that the home / outing flag for the user is set when the wireless LAN base station device 80 and the wireless terminal device 20 perform communication. However, the present invention is not limited to this, and the home / outing flag is registered as “at home” when the wireless LAN base station device 80 recognizes the user's wireless terminal device 20 continuously for a predetermined period of time. The home / outing flag may be registered as “outing” when the LAN base station device 80 has not been able to recognize the wireless terminal device 20 of the user continuously for a predetermined period. When the wireless terminal device 20 of the user who is registered as “at home” cannot be recognized continuously for a predetermined number of times or more, the user can determine that the user has gone out, so the display control device 10 is leaving the user. Register as a user.
