The distribution control unit 14 uses the viewing history information and the viewing request information from the user management unit 13 to control the distribution unit 16 to distribute the content requested to be viewed to the corresponding HMDs 40A and 40B. At this time, if the viewing history information includes information that the content requested to be viewed is partially viewed, the distribution control unit 14 controls the distribution unit 16 so that the content is viewed from the position where viewing was interrupted. Deliver to resume.

Note that the first server 10 may be configured to be able to distribute content supplied in real time from a distributor terminal (not shown). In that case, the first server 10 receives an acquisition unit (not shown) that acquires the content data supplied from the distributor terminal, and the content data and input information such as comments input from the HMDs 40A and 40B, for example. and a generation unit (not shown) that generates the used display content data, so that the display content data can be distributed to the HMDs 40A and 40B. Also, the second server 20 and the first server 10 may be configured to be able to distribute common content supplied in real time from a distributor terminal (not shown). In that case, the second server 20 and the first server 10 may share input information from the distributor terminal, input information from the viewer terminals 30A and 30B, and input information from the HMDs 40A and 40B.

FIG. 6 is a timing chart for explaining an example of the operation of the content distribution system equipped with the content distribution server of the first embodiment.
Here, a first viewer, who is a common user of the viewer terminal 30A and the HMD 40A, requests a change of the viewing device while using the video distribution service provided by the second server 20, and changes the viewing device to the viewer terminal. An example of the operation of the content distribution system when switching from 30A to HMD 40A will be described.

First, the first viewer transmits login request information from the viewer terminal 30A to the second server 20 (step SA1).
The second server 20 performs login processing for the first viewer based on the login request information received from the viewer terminal 30A, and notifies the viewer terminal 30A that the login has been completed (step SA2).

Subsequently, the first viewer operates the viewer terminal 30A to select content that he or she wishes to view, and transmits viewing request information to the second server 20 (step SA3).
The second server 20 acquires content data corresponding to the content selected by the first viewer from the content information storage unit DB2 based on the viewing request information received from the viewer terminal 30A, and distributes it to the viewer terminal 30A. (step SA4).

The first viewer transmits viewing switching request information to the second server 20 (selects the content for which the viewing device is to be changed) while viewing the content on the viewer terminal 30A (or when starting viewing). (Step SA5). At this time, if there are a plurality of options that the first viewer can select as the viewing device after switching, the first viewer may specify the viewing device and request the viewing switching.

When the second server 20 receives the switching request information from the viewer terminal 30A, for example, the display unit 35 of the viewer terminal 30A sends a confirmation message as to whether or not to stop distribution for switching to the viewer terminal 30A. After the display is made and a response to the effect of switching is obtained from the viewer terminal 30A, content distribution to the viewer terminal 30A is stopped based on the information included in the viewing switching request information (step SA6).

The second server 20 associates the time when the viewing switching request information was received and the viewing history of the content in which the first viewer changed the viewing device with the user identification information, records the viewing history in the user information storage unit DB3, and views the content. Using the user identification information included in the switching request information, at least part of the user information (second user information) stored in the user information storage unit DB3 (the user identification information, the time when the viewing switching request information was received, the viewing (including the identification information and the viewing history of the content for which the device has been changed) is acquired, and transmitted to the first server 10 together with the viewing switching request information (step SA7).

When the first server 10 acquires the viewing switching request information and at least part of the user information (second user information) of the second server 20 from the second server 20, the first server 10 accesses the user information storage unit DB1 and accesses the user information storage unit DB1. , the information associated with the user identification information included in the user information (second user information) of the second server 20 is updated (step SA8).

The first viewer activates the HMD 40A, for example, after making a viewing switching request at the viewer terminal 30A (step SA9). The timing at which the first viewer activates the HMD 40A is not limited to after the viewer terminal 30A makes a viewing switching request, and the HMD 40A may already be activated when the viewer terminal 30A requests viewing switching. No.

When the first viewer wears the HMD 40</b>A, the HMD 40</b>A transmits login information to the first server 10 . The HMD 40A determines whether or not the HMD 40A is worn by the first viewer using, for example, information acquired from the sensor 46. After determining that the viewer has worn the HMD 40A, the HMD 40A sends login request information to the first server 10. may be transmitted (step SA10).

When the first server 10 receives the login request information from the HMD 40A, the first server 10 compares the user identification information included in the login request information with the information stored in the user information storage unit DB1 to perform login processing. As a result of matching the information stored in the user information storage unit DB1 with the user identification information, when it is determined that it is the identification information of the first viewer registered as a user, the date and time of logging in to the user information storage unit DB1 is recorded. Then, a notification to the effect that the login is completed is transmitted to the HMD 40A (step SA11).

After the login of the first viewer of HMD 40A is completed, the first server 10 confirms the user information of the first viewer (including the first user information and the second user information) stored in the user information storage unit DB1. Then, when there is content for which the first viewer requests to change the viewing device at the viewer terminal 30A, the first viewer's login to the first server 10 starts from the time when the second server 20 receives the viewing switching request. is completed (or the time the login request information is received) is within a predetermined time (whether there is content selected by the first viewer in the second server 20) (step SA12).

When there is content selected by the first viewer on the second server 20, the first server 10 selects content (content selected by the first viewer on the second server 20) for which the viewing device is changed on the viewer terminal 30A. A message asking whether to continue viewing is displayed on the HMD 40A and presented to the first viewer (step SA13).

The first viewer operates the HMD 40A and transmits to the first server 10 a request to continue viewing the content for which the viewing device has been changed (step SA14).
When the first server 10 receives a request from the first viewer to continue viewing the content on which the viewing device has been changed by operating the HMD 40A, the first server 10 receives the user information of the second server 20 (the first 2 user information) (including the user identification information, the time when the viewing switching request information was received, the identification information of the content whose viewing was interrupted, and the viewing history), the first viewer uses the viewer terminal Distribution of the content for which the viewing device has been changed in 30A to HMD 40A is started from the position where viewing was interrupted (step SA15).

As described above, by switching the device on which the viewer views the content, the viewer does not need to reselect the content on the switched viewing device, and the viewer can continue viewing the content on a different viewing device. It can be done smoothly.

FIG. 7 is a timing chart for explaining another example of the operation of the content distribution system equipped with the content distribution server of the first embodiment.
Here, the operation of the content distribution system when the first viewer, who is a common user of the viewer terminal 30A and the HMD 40A, uses the video distribution service provided by the second server 20 and then switches the viewing device to the HMD 40A. An example of is explained.

In this example, steps SB1-SB4 are similar to steps SA1-SA4 described above.
When the first viewer suspends content viewing on the viewer terminal 30A (changes viewing equipment), for example, the first viewer operates the viewer terminal 30A to transmit stop request information to the second server 20 (step SB5 ).

When receiving the stop request information from the viewer terminal 30A, the second server 20 stops the content distribution to the viewer terminal 30A based on the information included in the stop request information (step SB6).
The second server 20 associates the time when the stop request information was received and the viewing history of the content interrupted by the first viewer with the user identification information, and records them in the user information storage unit DB1.

The first viewer activates the HMD 40A, for example, after making a viewing stop request using the viewer terminal 30A (step SB7). It should be noted that the timing at which the first viewer activates the HMD 40A is not limited to after the viewer terminal 30A makes a viewing stop request, and the HMD 40A may already be activated when the viewer terminal 30A requests viewing stop. No.

When the first viewer wears the HMD 40</b>A, the HMD 40</b>A transmits login information to the first server 10 . The HMD 40A determines whether or not the HMD 40A is worn by the first viewer using, for example, information acquired from the sensor 46. After determining that the viewer has worn the HMD 40A, the HMD 40A sends login request information to the first server 10. may be transmitted (step SB8).

When the first server 10 receives the login request information from the HMD 40A, the first server 10 compares the user identification information included in the login request information with the information stored in the user information storage unit DB1 to perform login processing. As a result of matching the information stored in the user information storage unit DB1 with the user identification information, when it is determined that the information is the identification information of the first viewer registered as a user, the date and time of login to the user information storage unit DB1 is recorded. , to the HMD 40A to notify that the login has been completed (step SB9).

After the login of the first viewer is completed, the first server 10 transmits request information for user information to the second server 20 (step SB10).
The second server 20 uses the user identification information included in the user information request information to store at least part of the user information (second user information) stored in the user information storage unit DB3 (user identification information and the stop request). (including the time when the information was received, the identification information of the content whose viewing was interrupted, and the viewing history) are acquired and transmitted to the first server 10 (step SB11).

When the first server 10 acquires at least part of the user information (second user information) of the second server 20 from the second server 20, the first server 10 accesses the user information storage unit DB1 to Information associated with the user identification information included in the information (second user information) is updated (step SB12).

The first server 10 confirms the user information of the first viewer (including the first user information and the second user information) stored in the user information storage unit DB1, and the first viewer views and listens on the viewer terminal 30A. is interrupted, the elapsed time from the time the second server 20 receives the stop request to the time the first server 10 completes the login of the first viewer (or the time the login request information is received) is within a predetermined time (whether there is content selected by the first viewer in the second server 20) (step SB13).

When there is content selected by the first viewer on the second server 20, the first server 10 reproduces the content (content selected by the first viewer on the second server 20) whose viewing was interrupted on the viewer terminal 30A. A message asking whether to continue viewing is displayed on the HMD 40A and presented to the first viewer (step SB14).

The first viewer operates the HMD 40A to transmit a request to continue viewing the interrupted content to the first server 10 (step SB15).
When the first server 10 receives a request from the first viewer to continue viewing the content for which viewing was interrupted, the first server 10 receives at least one of the user information (second user information) of the second server 20 stored in the user information storage unit DB1. (including the user identification information, the time when the stop request information was received, the identification information of the content whose viewing was interrupted, and the viewing history), the first viewer interrupted the viewing on the viewer terminal 30A (stop (requested) is started to be delivered to HMD 40A from the position where viewing was interrupted (step SB16).

When the viewer switches the device on which the content is viewed as described above, the viewer does not need to reselect the content that was interrupted to view on the switched viewing device, and continues viewing the content on a different viewing device. operation can be performed smoothly.

That is, according to the present embodiment, it is possible to provide a content distribution server, a content distribution method, a content distribution program, and a recording medium that enable a viewer to smoothly switch devices for viewing content. can.

Next, the viewer terminal, the viewer terminal control method, and the viewer terminal control program of the second embodiment will be described in detail with reference to the drawings. In the following description, the same reference numerals are given to the same configurations as in the above-described first embodiment, and the description thereof is omitted.
In this embodiment, the configurations of the first server 10, the second server 20, the viewer terminals 30A and 30B, and the HMDs 40A and 40B are different from the above-described first embodiment in the operation when switching the content viewing device. there is

FIG. 8 is a diagram schematically showing one configuration example of a viewer terminal according to the second embodiment.
In this embodiment, the HMDs 40A and 40B differ from the above-described first embodiment in the configuration of the control section 44. FIG.
The control unit 44 includes an information acquisition unit 44A and a judgment unit 44B.
The information acquisition unit 44A can start an operation for viewing content based on determination that the viewer has worn the HMDs 40A and 40B. For example, the information acquisition unit 44A may transmit login request information of the viewer from the communication unit 42 to the first server 10 based on determination that the viewer has worn the HMDs 40A and 40B.

Further, the information acquisition unit 44A can request predetermined information from the first server 10 via the network and acquire predetermined information transmitted from the first server 10 to the HMDs 40A and 40B. For example, the information acquisition unit 44A receives a notification from the first server 10 indicating that the login has been completed, or in response to the operation of the operation unit 43 by the viewer. At least part of the user information (second user information) is requested from the first server 10, and at least part of the viewer's user information (second user information) from the first server 10 to the second server 20 can be obtained.

At least part of the second user information is request information received from the viewer by the second server 20 (content viewing switching request information, content viewing request information, content distribution stop request information) and the reception time of these request information. information (at least one of information on the time when the content viewing switching request information is received, information on the time when the content viewing request information is received, and information on the time when the content stop request information is received), these requests It may include historical information for a predetermined period of time, including identification of content included in the information.

The determination unit 44B can determine whether or not the HMDs 40A and 40B are worn by the viewer, using information acquired from the sensor 46, for example.
Further, the determination unit 44B can determine whether or not there is content selected by the viewer in the second server 20 based on at least part of the second user information acquired by the information acquisition unit 44A.

For example, when at least part of the second user information includes information on the reception time of any one of the content viewing switching request information, the content viewing request information, and the content stop request information, the determining unit 44B When the elapsed time from the reception time to the time when the viewer logs in to the first server 10 (login completion time) is within a predetermined time, it is determined that there is content selected by the viewer at the second server 20. be able to.

For example, when the determination unit 44B determines that there is content selected by the viewer on the second server 20, or in response to the operation of the operation unit 43 by the viewer, the content is viewed from the communication unit 42 to the first server 10. Requests can be sent.
The control unit 44 receives content data such as video data and sound data from the first server 10 via the communication unit 42, and uses the received content data to present the content to the viewer through the display unit 45, the speaker 47, and the like. It is possible to

FIG. 9 is a timing chart for explaining an example of the operation of the content delivery system using the viewer terminal of the second embodiment.
Here, after the first viewer who is a common user of the viewer terminal 30A and the HMD 40A selects content to be viewed by the viewer terminal 30A, the first viewer wears the HMD 40A, logs in to the first server 10, and selects the content. An example of the operation of the content delivery system when content is viewed on the HMD 40A will be described.

First, the first viewer transmits login request information from the viewer terminal 30A to the second server 20 (step SC1).
The second server 20 performs a login process for the first viewer based on the login request information received from the viewer terminal 30A, and notifies the viewer terminal 30A that the login has been completed (step SC2).

Subsequently, the first viewer operates the viewer terminal 30A to select content that he or she wishes to view, and transmits viewing request information to the second server 20 (step SC3).
The second server 20 acquires content data corresponding to the content selected by the first viewer from the content information storage unit DB2 based on the viewing request information received from the viewer terminal 30A, and distributes it to the viewer terminal 30A. (step SC4).

The first viewer transmits viewing switching request information (viewing switching request information) to the second server 20 when viewing the content on the viewer terminal 30A (or when starting viewing or when stopping viewing). You can select the content to change the device). At this time, if there are a plurality of options that the first viewer can select as the viewing device after switching, the first viewer may specify the viewing device and request the viewing switching.
If the viewing request information from the viewer terminal 30A to the second server 20 includes information (viewing switching request information) designating the viewing device to the HMD 40A, the second server 20 omits step SC4. be able to.

The second server 20 associates the time when the viewing request information is received (or the time when the viewing switching request information is received), the identification information and viewing history of the content selected by the first viewer with the user identification information, At least part of the user information (second user information) stored in the user information storage unit DB3 (user identification information, (including the time when the viewing request information (or the viewing switching request information) was received, the identification information of the selected content, and the viewing history) are obtained and transmitted to the first server 10 (step SC5).

Note that the second server 20 may transmit at least part of the second user information to the first server 10 at a predetermined cycle, and may transmit at least part of the second user information to the first server 10 based on a predetermined operation. 10 , or at least part of the second user information may be transmitted to the first server 10 in response to a request from the first server 10 .

When the first server 10 acquires at least a part of the second user information from the second server 20, the first server 10 accesses the user information storage unit DB1 to obtain information included in the user information of the second server 20 (second user information). update the information associated with the received user identification information (step SC6).

The first viewer may activate the HMD 40A, for example, after making a viewing request or a viewing switching request on the viewer terminal 30A. It should be noted that the timing at which the first viewer activates the HMD 40A is not limited to after the viewer terminal 30A makes a viewing request or a viewing switching request, but rather when the viewer terminal 30A issues a viewing request or a viewing switching request. It doesn't matter if it is running.

When the first viewer wears the HMD 40</b>A, the HMD 40</b>A transmits login request information to the first server 10 . The HMD 40A determines whether or not the HMD 40A is worn by the first viewer using, for example, information acquired from the sensor 46. After determining that the viewer has worn the HMD 40A, the HMD 40A sends login request information to the first server 10. may be transmitted (step SC7).

When the first server 10 receives the login request information from the HMD 40A, the first server 10 compares the user identification information included in the login request information with the information stored in the user information storage unit DB1 to perform login processing. As a result of matching the information stored in the user information storage unit DB1 with the user identification information, when it is determined that it is the identification information of the first viewer registered as a user, the date and time of logging in to the user information storage unit DB1 is recorded. Then, a notification to the effect that the login is completed is transmitted to the HMD 40A (step SC8).

Upon receiving the login completion notification from the first server 10, the HMD 40A requests at least part of the second user information of the first viewer from the first server 10 (step SC9).
In response to the request from HMD 40A, first server 10 transmits at least part of the second user information of the first viewer stored in user information storage DB1 to HMD 40A (step SC10).

The HMD 40A can confirm at least part of the second user information of the first viewer received from the first server 10 and determine whether or not there is content selected by the first viewer on the viewer terminal 30A. . The HMD 40A, for example, from the time when the second server 20 receives the viewing request (or the viewing switching request) to the time when the login of the first viewer to the first server 10 is completed (or the time when the login request information is received). It is determined whether the elapsed time until is within a predetermined time, and when the elapsed time is within the predetermined time, the content for which the viewing request (or viewing switching request) is made is selected by the first viewer in the second server 20. It can be determined that the content is the content that has been created (step SC11).

Here, when there is content selected by the first viewer on the second server 20, the HMD 40A displays on the HMD 40A a message asking whether to continue viewing the content selected by the first viewer on the second server 20. may be presented to the first viewer.
In this case, the first viewer can operate the HMD 40A to transmit to the first server 10 a request to continue viewing the selected content.

Based on the determination that there is selected content (or by the operation of the first viewer), HMD 40A transmits viewing request information for the content selected by the first viewer to first server 10 (step SC12).
The first server 10 distributes the content selected by the first viewer with the viewer terminal 30A to the HMD 40A based on the viewing request information (including the content identification information) from the HMD 40A (step SC13).

Subsequently, the first server 10 may notify the second server 20 that the switching of viewing has been completed (step SC14). The second server 20 can stop distribution of the selected content to the viewer terminal 30A based on receiving the viewing switching completion notification from the first server 10 (step SC15). Note that if step SC4 described above is omitted, steps SC14 and SC15 may be omitted.

By selecting the content to be viewed by the viewer as described above, the viewer can select the content to be viewed on the HMD 40A by operating the viewer terminal 30A. You can smoothly perform the operation when viewing the content with.

FIG. 10 is a timing chart for explaining another example of the operation of the content delivery system using the viewer terminal of the second embodiment.
Here, a first viewer who is a common user of the viewer terminal 30A and the HMD 40A wears the HMD 40A and logs into the first server 10, selects content to be viewed with the viewer terminal 30A, and uses the HMD 40A. An example of the operation of the content delivery system when viewing the content selected by the operation on the HMD 40A will be described.

When the first viewer wears the HMD 40</b>A, the HMD 40</b>A transmits login request information to the first server 10 . The HMD 40A determines whether or not the HMD 40A is worn by the first viewer using, for example, information acquired from the sensor 46. After determining that the viewer has worn the HMD 40A, the HMD 40A sends login request information to the first server 10. may be transmitted (step SD1).

When the first server 10 receives the login request information from the HMD 40A, the first server 10 compares the user identification information included in the login request information with the information stored in the user information storage unit DB1 to perform login processing. As a result of matching the information stored in the user information storage unit DB1 with the user identification information, when it is determined that it is the identification information of the first viewer registered as a user, the date and time of logging in to the user information storage unit DB1 is recorded. Then, a notification to the effect that the login is completed is transmitted to the HMD 40A (step SD2).

Upon receiving the login completion notification from the first server 10, the HMD 40A requests at least part of the second user information of the first viewer from the first server 10 (step SD3).
In response to the request from HMD 40A, first server 10 transmits at least part of the second user information of the first viewer stored in user information storage DB1 to HMD 40A (step SD4).

The HMD 40A can confirm at least part of the second user information of the first viewer received from the first server 10 and determine whether or not there is content selected by the first viewer on the viewer terminal 30A. . The HMD 40A, for example, from the time when the second server 20 receives the viewing request (or the viewing switching request) to the time when the login of the first viewer to the first server 10 is completed (or the time when the login request information is received). It is determined whether or not the elapsed time is within a predetermined time, and when the time is within the predetermined time, the content for which the viewing request (or viewing switching request) is made is the content selected by the first viewer in the second server 20. It can be determined that there is (step SD5).

In this example, the HMD 40A determines that there is no content selected by the first viewer on the second server 20 . When there is no content selected by the first viewer on the second server 20, the HMD 40A may, for example, notify the first server 10 that there is no selected content, and the normal menu screen is displayed on the first viewer. may be presented.

Later, the first viewer transmits login request information from the viewer terminal 30A to the second server 20 (step SD6).
The second server 20 performs login processing for the first viewer based on the login request information received from the viewer terminal 30A, and notifies the viewer terminal 30A that the login has been completed (step SD7).

Subsequently, the first viewer operates the viewer terminal 30A to select content that he or she wishes to view, and transmits viewing request information to the second server 20 (step SD8).
The second server 20 acquires content data corresponding to the content selected by the first viewer from the content information storage unit DB2 based on the viewing request information received from the viewer terminal 30A, and distributes it to the viewer terminal 30A. (step SD9).

Note that the first viewer sends viewing switching request information to the second server 20 when viewing the content on the viewer terminal 30A (or when starting viewing or when stopping viewing of the content). You can send (select content that changes the viewing device). At this time, if there are a plurality of options that the first viewer can select as the viewing device after switching, the first viewer may specify the viewing device and request the viewing switching.
If the content viewing request information from the viewer terminal 30A to the second server 20 includes information (viewing switching request information) designating the viewing device to the HMD 40A, the second server 20 performs step SD9. can be omitted.

The second server 20 associates the time when the viewing request information is received (or the time when the viewing switching request information is received), the identification information and viewing history of the content selected by the first viewer with the user identification information, At least part of the user information (second user information) stored in the user information storage unit DB3 (user identification information, (including the time when the viewing request information (or the viewing switching request information) was received, the identification information of the selected content, and the viewing history) are acquired and transmitted to the first server 10 (step SD10).

Note that the second server 20 may transmit at least part of the second user information to the first server 10 at a predetermined cycle, and may transmit at least part of the second user information to the first server 10 based on a predetermined operation. 10 , or at least part of the second user information may be transmitted to the first server 10 in response to a request from the first server 10 .

When the first server 10 acquires at least a part of the second user information from the second server 20, the first server 10 accesses the user information storage unit DB1 to obtain information included in the user information of the second server 20 (second user information). The information associated with the received user identification information is updated (step SD11).

The first viewer can request user information from the first server 10 by operating the HMD 40A, for example, after making a viewing request or a viewing switching request on the viewer terminal 30A.
The HMD 40A requests at least part of the second user information of the first viewer from the first server 10 according to the operation of the first viewer (step SD12).
In response to the request from HMD 40A, first server 10 transmits at least part of the second user information of the first viewer stored in user information storage DB1 to HMD 40A (step SD13).

The HMD 40A can confirm at least part of the second user information of the first viewer received from the first server 10 and determine whether or not there is content selected by the first viewer on the viewer terminal 30A. . The HMD 40A, for example, from the time when the second server 20 receives the viewing request (or the viewing switching request) to the time when the login of the first viewer to the first server 10 is completed (or the time when the login request information is received). It is determined whether the time until is within a predetermined time, and when the time is within the predetermined time, the content for which the viewing request (or viewing switching request) is made is the content selected by the first viewer in the second server 20. can be determined (step SD14).

Here, when there is content selected by the first viewer on the second server 20, the HMD 40A displays on the HMD 40A a message asking whether to continue viewing the content selected by the first viewer on the second server 20. may be presented to the first viewer.
In this case, the first viewer can operate the HMD 40A to transmit to the first server 10 a request to continue viewing the selected content.

The HMD 40A transmits viewing request information for the content selected by the first viewer to the first server 10 based on the judgment that there is the selected content (or by the operation of the first viewer) (step SD15).
The first server 10 distributes the content selected by the first viewer with the viewer terminal 30A to the HMD 40A based on the viewing request information (including the content identification information) from the HMD 40A (step SD16).

Subsequently, the first server 10 may notify the second server 20 that the switching of viewing has been completed (step SD17). The second server 20 can stop distribution of the selected content to the viewer terminal 30A based on receiving the viewing switching completion notification from the first server 10 (step SD18). Note that if step SD9 described above is omitted, steps SD17 and SD18 may be omitted.

By selecting the content to be viewed by the viewer as described above, the viewer can select the content to be viewed on the HMD 40A by operating the viewer terminal 30A. You can smoothly perform the operation when viewing the content with.
