- the pairing management unit 22 determines whether a device is included in the generated home device list (S5).
- the pairing management unit 22 determines a pairing cancellation candidate from the home device list based on the information indicating the stay time in the home (S6). .
- the pairing management unit 22 sorts the home device list in descending order using the home residence time as a key, and determines the first device, that is, the device with the longest home residence time, as a pairing release candidate. Then, the pairing management unit 22 presents the determined pairing cancellation candidates to the user, for example, by displaying them on the display unit 5 (S7).
- the pairing management unit 22 selects the cancellation candidate from the non-home device list based on the information indicating the content acquisition frequency from outside the home. (S8). Specifically, the pairing management unit 22 selects the first device that sorts the non-home device list in ascending order using the frequency as a key, that is, the device with the lowest frequency.
- the pairing management unit 22 determines whether content is being viewed on the selected device (S9). Specifically, when the device that is transmitting the content matches the device selected in S8, the distribution unit 21 determines that the device is currently viewing the content.
- the process proceeds to S7, and the cancellation candidate selected in S8 is presented to the user.
- the pairing management unit 22 determines the next candidate as a cancellation candidate (S10), proceeds to the processing of S7, and presents the cancellation candidate to the user.
- next candidate is a device having the second lowest frequency among the devices included in the non-home device list.
- the number of devices that can receive content distribution from the server 1 from outside the home is limited to one, even in the device with the second lowest frequency, The content distributed from the server 1 cannot be viewed.
- the determination in S9 may be performed until devices with no content viewing are found in order for devices with the second and subsequent frequencies.
- the pairing management unit 22 determines whether the user has agreed to cancel the pairing of the cancellation candidate (S11). For example, an option for whether or not to cancel can be displayed on the display unit 5 and the above determination can be made according to the content selected by the user.
- the pairing management unit 22 performs an exception process (S12) and ends the pairing process.
- the next cancellation candidate for example, the device with the longest residence time next to the cancellation candidate for which consent has not been obtained, or the frequency of content acquisition from outside the house next to the cancellation candidate for which consent has not been obtained is low.
- the process of presenting the device to the user may be repeated until the user's consent is obtained.
- the registered devices are displayed in a list (FIG. 5A) together with information for each device such as presence / absence in the home, residence time, frequency, etc., and the user is allowed to select a device to be paired. The user may be prompted to select a device to cancel pairing, or the pairing may not be canceled and the requested pairing may not be performed.
- the pairing management unit 22 deletes the cancellation candidate device from the paired device management information, and Pairing is canceled (S13). Then, the pairing management unit 22 instructs the pairing unit 23 to execute pairing with the client device (S14), updates the pair device management information (S15), and ends the pairing process.
- FIG. 5 is a diagram illustrating an example of an image presented to the user.
- the number of devices that can be paired has already reached the upper limit, and it is necessary to select a device to cancel pairing for a new pairing.
- a message indicating is included.
- the device ID of the device that has made the pairing request is included.
- the client device information is not deleted from the paired device management information, but information indicating that pairing is cancelled is added and left in the paired device management information.
- the residence time and the like can be presented as in the illustrated example. Of course, presentation of information such as residence time is not essential.
- the image of (a) in the figure includes an option for selecting whether or not pairing can be executed and a list of paired devices.
- cancellation candidates determined by the server 1 are focused (highlighted), and a cursor (arrow) for the user to select a device to be canceled is placed on the cancellation candidates.
- the user can easily select an appropriate release candidate. You can choose. Although only the cancellation candidates determined by the server 1 may be presented to the user, it is preferable to display other devices in a selectable manner because the range of selection by the user is widened. In the illustrated example, one cancellation candidate determined by the server 1 is highlighted. However, a plurality of cancellation candidates may be highlighted and presented in a similar manner, and it is considered more appropriate as a cancellation candidate. A plurality of release candidates may be presented in order.
- an image as shown in (b) of the figure is displayed, and the user can confirm whether or not pairing with the selected device can be canceled.
- the image of (b) in the figure shows the ID of the device selected by the user, information indicating that the device is a pairing cancellation candidate, and the judgment criteria for selecting the device as a cancellation candidate.
- the residence time of the device is shown.
- the image includes a message inquiring whether or not pairing of the device can be canceled and an option for selecting whether or not the device can be paired.
- the user By displaying such an image, the user has a long residence time at home, and is unlikely to be used for viewing content outside the home, or even when pairing is canceled, It is possible to recognize that a device that is easily paired again is a release candidate. Based on such recognition, it is possible to make a final determination as to whether or not to cancel pairing with the device.
- FIGS. 5A and 5B may be displayed on the client device, and the server 1 uses the input content of the user input to the client device based on this image as the client device. May be received and the determination of S11 may be made.
- registered client devices existing in the home are set as release candidates in preference to client devices that have not been confirmed to exist in the home. This is because a client device connected to the home LAN can receive desired content from the server 1 even if the pairing is canceled. Further, as described above, it is assumed here that pairing is possible only when connected to the home LAN. For this reason, even if it is a case where the pairing of the client apparatus contrary to a user's will is cancelled
- all the client devices determined to be present in the home in (1) may be set as cancellation candidates.
- the cancellation candidate may be determined by using only the criterion (2) or (3) or a combination of these criteria without using the criterion (1).
- cancellation candidates may be determined by combinations of all the criteria (1) to (3).
- the selection criteria for cancellation candidates are not limited to the above examples (1) to (3).
- a client device having a long period of time during which no viewing (reception of content from the server 1) has been performed may be given priority as a cancellation candidate. This is because client devices that have not been used for viewing outside the home for a long period of time are often less affected even when pairing is canceled.
- the server 1 may be provided with a non-reception period specifying unit (non-reception period specifying unit) that acquires non-reception period information indicating a period during which the client device does not receive content from the server 1 outside the home LAN. . Then, based on the non-reception period information, the pairing management unit 11 may preferentially select a client device having a longer period of not receiving content as a cancellation candidate.
- the timing at which the content is last received may be the timing at which the content transmission request is received, the timing at which the content transmission is started, or the timing at which the content transmission is terminated. Also good. Further, this timing may be indicated by a date and time, or may be indicated by a date. Furthermore, instead of such a recent non-reception period, a cumulative non-reception period may be used.
- the priority of pairing may be set for the client device, and the client device with a lower priority may be given priority as a release candidate.
- the priority may be set based on this information by registering information about the paired client device at the time of the first pairing, for example. Specifically, for example, a parent-child relationship, age, and the like may be registered for a user of a client device, and it may be determined that a parent has a higher priority than a child and an older person has a higher priority than a younger person.
- the priority may be set by the user, and a client device with a low priority may be given priority as a cancellation candidate.
- the server 1 may be provided with a priority determination unit (priority determination unit) that determines the priority of the client device based on information about the client device registered in advance. And the pairing management part 11 should just select a cancellation
- a priority determination unit priority determination unit
- a client device with a shorter usage time or a lower usage frequency may be given priority as a cancellation candidate. This is because a client device having a high usage frequency is considered to have a larger influence when pairing is canceled than a client device having a low usage frequency.
- the server 1 may be provided with a usage status specifying unit (usage status specifying unit) that specifies the accumulated usage time or usage frequency of the client device. Then, the pairing management unit 11 may prioritize the client device with the shorter cumulative usage time specified by the usage status specifying unit or the client device with a lower usage frequency as a cancellation candidate.
- the accumulated usage time may be obtained by measuring the time that the device is used (for example, the time when the power is on and not in the sleep state) in the client device, and acquiring the measured time from the device. Good.
- the frequency of use for example, in a client device, counts the number of times that the device has been used (number of times of use) (for example, the number of times the power is turned on or the sleep state is canceled). You may acquire from this apparatus. And it is good also considering the frequency
- the number and frequency of use in a predetermined manner for example, usage for viewing content, use of a specific application, etc. are not limited to the number and frequency acquired from the server 1) may be used. .
- Appropriate cancellation candidates can be selected by combining various criteria as described above alone or appropriately.
- the pairing requesting device has a lower priority for pairing, and it is determined that the pairing is canceled rather than the pairing cancellation based on the above criteria. It may be more appropriate to cancel a ring request. In such a case, a message to that effect may be presented to the user to select whether to cancel the pairing request. Thereby, in order to pair with a low priority apparatus, it can prevent releasing a pairing of a high priority apparatus.
- the priority determination unit (priority determination unit) that determines whether the server 1 has a lower registration priority than the paired client device according to a predetermined criterion. May be provided. Then, when the priority determination unit determines that the device that is the source of the pairing request has a lower registration priority than the paired client device, the pairing management unit 11 displays the determination result. Notify the user and select whether or not to accept a pairing request.
- the above criterion may be the same as the criterion for selecting a cancellation candidate.
- the cancellation candidate may be selected from all paired client devices and devices that have requested pairing.
- the priority level may be determined between the cancellation candidate and a device requesting pairing. In any of these configurations, it is possible to prevent pairing of a client device having a high priority from being canceled.
- the pairing management unit 11 selects one cancellation candidate according to the above criteria, cancels the pairing of the selected cancellation candidate, and instead performs pairing with the transmission source device of the pairing request. .
- pairing cancellation may be automatically performed when a client device that is a cancellation candidate satisfies requirements such as not acquiring content from outside the home for a predetermined period (for example, one year). .
- the control block (especially the control unit 2) of the server 1 may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or realized by software using a CPU (Central Processing Unit). May be.
- a logic circuit hardware
- IC chip integrated circuit
- CPU Central Processing Unit
- the server 1 includes a CPU that executes instructions of a program that is software that implements each function, a ROM (Read Only Memory) or storage in which the above-described program and various data are recorded so as to be readable by a computer (or CPU).
- a device (these are referred to as “recording media”), a RAM (Random Access Memory) for expanding the program, and the like are provided.

- Reference Example 1-1 A reference example of the present invention will be described with reference to FIGS. In this reference example, a configuration will be described in which a user of a certain client device can easily recognize that there is a viewing request (content transmission request) from another client device.
- Figure 7 shows an overview of the content transmission system according to this reference example. 7 shows four client devices 100a to 100d, it is assumed that the server 20 is paired with six client devices including the four client devices.
- the client device may be a device dedicated to the server 20 (slave device) or a general-purpose device such as a mobile phone or a smartphone.
- the server 20 according to the reference example 1-1 has the same configuration as the server 1 described in the first and second embodiments. That is, the server 20 includes a control unit 2, a storage unit 3, a communication unit 4, a display unit 5, an input unit 6, and a content memory 7 (see FIG. 1). However, as described below, the function of the control unit 2 is different from that of the above embodiment.
- the information processing apparatus (server 20) according to Reference Example 1-1 is a content transmission system that transmits content to a registered device in response to a viewing request from a registered device (client devices 100a to 100d) registered in advance.
- An information processing apparatus that limits the number of registered devices that simultaneously receive content, and when content viewing requests are received when the number of registered devices that simultaneously receive content has reached the upper limit,
- the control unit (2) includes a notification unit that notifies the registered device that has received the notification that the content viewing request has been received from another registered device.
- a certain client device is receiving content from the server 20 (that is, a user of the client device is viewing the content, and a user of another client device cannot view the content).
- the client device is expressed as “viewing right”.
- the user of the second client device wants to view the content immediately, it is necessary to search for the user of the first client device having the viewing right and request to stop viewing the content. Also, the user of the first client device cannot recognize that there is a viewing request from the second client device even if he / she thinks that viewing of the content may be stopped if there is a viewing request of another user.

Description
以下、本発明の実施の形態について、詳細に説明する。まず、図2に基づいて、本実施形態に係るコンテンツ送信システムの概要を説明する。図2は、コンテンツ送信システムの概要を示す図である。
次に、サーバ1の構成を図1に基づいて説明する。図1は、サーバ1の要部構成を示すブロック図である。図示のように、サーバ1は、制御部2、記憶部3、通信部4、表示部5、入力部6、およびコンテンツメモリ7を備えている。
続いて、ペア機器管理情報の詳細を図3に基づいて説明する。図3は、ペア機器管理情報の一例を示す図である。図示のペア機器管理情報は、機器IDと、通信アドレスと、宅内存否を示す情報と、宅内滞留時間を示す情報と、宅外からのコンテンツ取得頻度を示す情報とが対応付けられたテーブル形式の情報である。
次に、サーバ1が実行するペアリング処理の流れを図6に基づいて説明する。図6は、ペアリング処理の一例を示すフローチャートである。なお、同図の処理は、クライアント機器からのペアリング要求の受信を契機として開始される。また、サーバ1は、ペアリング要求と共に、クライアント機器の機器IDを受信しているとする。
上記実施形態では、下記(1)の基準で宅内に存在すると判定されたクライアント機器のうち、下記(2)の宅内滞留時間が最も長いクライアント機器を解除候補とする例を説明した。また、下記(1)の基準で宅内には存在しないと判定されたクライアント機器のうち、下記(3)の宅外からのコンテンツ取得頻度が最も低いクライアント機器を解除候補とする例を説明した。
(1)宅内存否(宅内のクライアント機器を優先して解除候補とする)
(2)宅内滞留時間(宅内滞留時間の長いクライアント機器を優先して解除候補とする)
(3)宅外取得頻度(宅外からのコンテンツ取得頻度が低いクライアント機器を優先して解除候補とする)
しかしながら、解除候補の選択は、必ずしも上記のような組み合わせで行う必要はない。例えば、(1)で宅内に存在すると判定されたクライアント機器を全て解除候補としてもよい。また、(1)の基準は用いずに、(2)または(3)の基準のみ、あるいはこれらの基準の組み合わせにより、解除候補を決定してもよい。さらに、(1)~(3)の全ての基準の組み合わせにより、解除候補を決定してもよい。
以上のようにして選択した解除候補ではあっても、ペアリング要求している機器の方がペアリングの優先度が低く、上記のような基準から判断して、ペアリング解除するよりも、ペアリング要求をキャンセルする方が妥当な場合がある。このような場合には、その旨をユーザに提示して、ペアリング要求のキャンセルの可否を選択させてもよい。これにより、優先度の低い機器とペアリングするために、優先度の高い機器のペアリングを解除してしまうことを防ぐことができる。
上記実施形態では、解除候補をユーザに提示して、最終的な解除の可否はユーザに選択させる例を説明したが、ユーザを介することなく、自動で解除候補のペアリングを解除してもよい。この場合、ペアリング管理部11は、上記のような基準に従って1つの解除候補を選択し、選択した解除候補のペアリングを解除して、代わりにペアリング要求の送信元の機器とペアリングさせる。
上記実施形態では、サーバ1がコンテンツの送信と、ペアリングの管理との両方を行う例を示したが、これらを個別の装置で行うようにしてもよい。例えば、コンテンツ要求を受信し、該要求に応じてコンテンツを送信するコンテンツ送信装置と、ペアリング要求を受信し、該要求に応じてペアリングする情報処理装置とを含むシステムであっても、サーバ1と同様の機能を実現できる。このようなシステムでは、解除候補の決定および提示のための処理を上記情報処理装置で行ってもよいし、コンテンツ送信装置で行ってもよい。
