The storage unit 13 may set the priority of the program introduction video higher than other introduction data. The storage unit 13 may set a priority for each program introduction video so that the stored program introduction video is distributed with priority over general introduction data distributed to viewers of the content in a similar manner. For example, a program introduction video related to a live broadcast that is desired to attract many viewers for some reason, such as a program that needs promotion because it is an important live broadcast, may be set to a high priority.

[0039] The clock unit 14 is composed of an oscillator circuit and a variable PLL (Phase Locked Loop) for generating a clock signal, a counter circuit for counting the number of pulses of the clock signal, etc. The clock unit 14 measures the time based on the number of pulses counted. The control unit 11 executes various controls at timings based on the number of pulses counted by the clock unit 14. The control unit 11 also counts the elapsed time from the start of the content and determines whether a predetermined time has elapsed based on the time measured by the clock unit 14.

[0040] The following describes the functional configuration of the control unit 11. The control unit 11 functions as a content acquisition unit 110, a content distribution unit 111, an introduction video processing unit 112, an introduction video distribution unit 113, and a user information acquisition unit 114. Each unit can be read as the control unit 11 or a processor.

[0041] The content acquisition unit 110 acquires live broadcast content data from the distributor terminal 2 via the communication unit 12. The content acquisition unit 110 acquires video content data for time-shift distribution from the distributor terminal 2 via the communication unit 12. The content acquisition unit 110 stores the content data in the storage unit 13. In the following description, "acquire" may be read as "receive." Live broadcast content data is also referred to as live broadcast content.

[0042] The content distribution unit 111 distributes content data to the viewer terminal 3 via the communication unit 12. For example, the content distribution unit 111 acquires a distribution request from the viewer terminal 3 via a network. In response to the distribution request received from the viewer terminal 3, the content distribution unit 111 acquires the content data for which the distribution request has been received from the storage unit 13, and distributes the content data to the viewer terminal 3. The distribution request from the viewer terminal 3 may include user identification information and content identification information. The user identification information is information that identifies the user who inputs the distribution request. The content data for which the distribution request has been received is also referred to as viewing content. The viewing content is also referred to as selected content selected by the viewer of the viewer terminal 3.

[0043] The content distribution unit 111 may manage the start and end of content data distribution based on, for example, time information obtained from the clock unit 14 and the distribution time of the content data. Note that the content distribution unit 111 may manage the start and end of real-time distribution so that the content distribution starts in real time when live broadcast content data is received, and the content distribution ends when the live broadcast content data ends.

[0044] The content distribution unit 111 distributes live broadcast content related to the program introduction video to the viewer terminal 3 via the communication unit 12. The content distribution unit 111 determines whether or not a selection operation of the program introduction video has been performed by the viewer of the viewer terminal 3. The content distribution unit 111 distributes live broadcast content related to the program introduction video to the viewer terminal 3 based on the selection operation of the program introduction video by the viewer of the viewer terminal 3. The selection operation of the program introduction video is an example of a selection operation of information for distributing live broadcast content. The selection operation of the program introduction video includes an input operation of selecting the program introduction video by the viewer of the viewer terminal 3. The content distribution unit 111 determines whether or not a selection operation of the program introduction video has been performed based on the input operation of selecting the program introduction video. The input operation of selecting the program introduction video includes, for example, an operation of selecting link information that can access the live broadcast content related to the program introduction video. The input operation of selecting the program introduction video includes, for example, an operation of selecting a button or the like that can access the live broadcast content related to the program introduction video. The content distribution unit 111 distributes live broadcast content related to the program introduction video to the viewer terminal 3 based on the determination that a selection operation of the program introduction video has been performed. The content distribution unit 111 distributes live broadcast content related to the program introduction video to the viewer terminal 3 in real time based on an input operation to select the program introduction video. For example, if the time when the viewer of the viewer terminal 3 performs an input operation to select the program introduction video is 10 minutes after the start of distribution of the live broadcast content, the content distribution unit 111 distributes the content from 10 minutes after the start of distribution of the live broadcast content to the viewer terminal 3. The content distribution unit 111 may distribute the live broadcast content related to the program introduction video to the viewer terminal 3 from the beginning of the content based on an input operation to select the program introduction video. In this case, the content distribution unit 111 distributes the live broadcast content to the viewer terminal 3 by time shift distribution. The content distribution unit 111 may distribute the live broadcast content related to the program introduction video instead of the viewing content based on an input operation to select the program introduction video.

[0045] The content distribution unit 111 determines whether the program introduction video has ended. The content distribution unit 111 distributes viewing content based on the end of the program introduction video. The content distribution unit 111 may distribute viewing content instead of the program introduction video. The end of the program introduction video includes the end of the playback time of the program introduction video and being forced to terminate by the viewer of the viewer terminal 3. Being forced to terminate includes a skip operation by the viewer of the viewer terminal 3. The skip operation is an operation for skipping the program introduction video. The skip operation includes an operation to request the distribution of viewing content. The skip operation includes an input operation of a skip button or the like by the viewer of the viewer terminal 3.

[0046] The content distribution unit 111 may immediately discard the distributed content data, or may buffer the data for a predetermined period of time to enable replay or slow-motion playback, for example.

[0047] The introduction video processing unit 112 creates a program introduction video based on the live broadcast content. The introduction video processing unit 112 creates a program introduction video at a predetermined timing. The predetermined timing includes the start time of the live broadcast content, a predetermined time after the start of the live broadcast content, a predetermined time interval after the start of the live broadcast content, etc. The predetermined time is, for example, 5 minutes, etc. The predetermined time interval is, for example, every 10 minutes, etc. The introduction video processing unit 112 determines whether or not the predetermined timing is satisfied based on the progress of the live broadcast content. For example, the introduction video processing unit 112 may create a program introduction video based on the start of distribution of the live broadcast content. The introduction video processing unit 112 may create a program introduction video 5 minutes after distribution of the live broadcast content starts. The introduction video processing unit 112 may create a program introduction video every 10 minutes after distribution of the live broadcast content starts.

[0048] The introduction video processing unit 112 cuts out a predetermined amount of content data from the live broadcast content. The predetermined amount of time is, for example, 30 seconds. For example, the introduction video processing unit 112 cuts out 30 seconds of content data from the start of the distribution of the live broadcast content. The introduction video processing unit 112 may cut out a predetermined amount of content data at a predetermined time interval from the start of the distribution of the live broadcast content. For example, the introduction video processing unit 112 cuts out 30 seconds of content data every 10 minutes from the start of the distribution of the live broadcast content.

[0049] The introduction video processing unit 112 may create a program introduction video based on a predetermined condition in the live broadcast content. The predetermined condition may be, for example, a break in the audio of the live broadcast content, a break in the scene, or other break in the content. By extracting the content data based on the break in the content, a program introduction video that is easy to watch can be created. The predetermined condition may be, for example, the excitement of the live broadcast content. The introduction video processing unit 112 may determine the excitement of the live broadcast content based on the number of comments from viewers on the live broadcast content, the volume, or the like. By extracting the content data based on the excitement of the content, a program introduction video that is likely to interest viewers can be created.

[0050] The introduction video processing unit 112 creates a program introduction video based on the cut-out content data. For example, the introduction video processing unit 112 adds information that enables the cut-out content data to be recognized as a program introduction video. The introduction video processing unit 112 may combine a jingle, text information, an image, an icon, or the like, indicating that the content data is a program introduction video, with the cut-out content data. The jingle may be, for example, a sound effect indicating that the program introduction video is about to start. The text information may include information for introducing live broadcast content, such as "This program is on." When the introduction video processing unit 112 cuts out multiple pieces of content data, it may combine the multiple pieces of cut content data to create a program introduction video.

[0051] The introduction video processing unit 112 stores the created program introduction video in the storage unit 13. The introduction video processing unit 112 may store the program introduction video in the storage unit 13 every time the introduction video is created. The introduction video processing unit 112 may update the program introduction video every time the introduction video is created. The introduction video processing unit 112 may store time information when the program introduction video was created in association with the program introduction video.

[0052] The introduction video distribution unit 113 distributes the program introduction video to the viewer terminal 3 of the viewer who is viewing selected content different from the live broadcast content introduced in the program introduction video. The introduction video distribution unit 113 distributes the program introduction video to the viewer terminal 3 who is viewing, for example, video content of time shift distribution. The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 who is viewing selected live broadcast content different from the live broadcast content introduced in the program introduction video. The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 who is viewing still image content. The viewer terminal 3 acquires the program introduction video. The processor of the viewer terminal 3 realizes an acquisition unit that acquires the program introduction video. The viewer terminal 3 displays the acquired program introduction video on a display device not shown. The processor of the viewer terminal 3 realizes a display control unit that displays the program introduction video.

[0053] The introduction video distribution unit 113 distributes to the viewer terminal 3 a program introduction video based on live broadcast content related to the content requested for distribution by the viewer of the viewer terminal 3. The content requested for distribution by the viewer of the viewer terminal 3 is also called viewing content. The live broadcast content related to the viewing content is also called related live broadcast content. The introduction video distribution unit 113 may determine the related live broadcast content based on genre information. For example, the introduction video distribution unit 113 may determine live broadcast content that has a common genre with the viewing content as the related live broadcast content. Specifically, when the viewer of the viewer terminal 3 is going to watch an anime, the introduction video distribution unit 113 may determine live broadcast content related to the anime as the related live broadcast content. The introduction video distribution unit 113 may determine the related live broadcast content based on keyword information. For example, the introduction video distribution unit 113 may determine live broadcast content that includes a keyword common to the viewing content as the related live broadcast content. Specifically, when a viewer of the viewer terminal 3 is about to view a content having “Pomeranian” as keyword information, the introduction video distribution unit 113 may set a live broadcast content having “Pomeranian” as keyword information as a related live broadcast content. The viewed content may be associated with at least one related live broadcast content.

[0054] The introduction video distribution unit 113 may determine the related live broadcast content based on the user information of the viewer of the viewer terminal 3. For example, the introduction video distribution unit 113 may determine live broadcast content related to previously viewed content as the related live broadcast content based on the viewing history of the viewer of the viewer terminal 3. Specifically, if the viewer of the viewer terminal 3 has viewed content related to animals in the past, the introduction video distribution unit 113 may determine live broadcast content related to animals as the related live broadcast content. The introduction video distribution unit 113 may determine the related live broadcast content based on the user's preference information. For example, if the viewer of the viewer terminal 3 has set "cats" as preference information, the introduction video distribution unit 113 may determine live broadcast content related to "cats" as the related live broadcast content. The introduction video distribution unit 113 distributes the program introduction video created based on the related live broadcast content to the viewer terminal 3.

[0055] The introduction video distribution unit 113 judges whether or not a predetermined timing is satisfied. Based on the judgment result, the introduction video distribution unit 113 distributes the program introduction video to the viewer terminal 3 when the predetermined timing is satisfied. The predetermined timing includes, for example, before the start of distribution of the viewing content, after a predetermined time has elapsed since the start of distribution of the viewing content, and every certain time. Before the start of distribution of the viewing content is also called before the start of the viewing content. The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 before the start of the viewing content. The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 15 minutes after the start of the viewing content. The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 every 10 minutes after the start of the viewing content.

[0056] The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that the program introduction video can be displayed on the viewer terminal 3 while the viewer is viewing the viewing content. For example, the introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that the program introduction video can be displayed in a display area different from the area in which the viewing content is displayed on the viewer terminal 3. The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that the program introduction video can be displayed in a Picture-in-Picture (PinP) format. The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that the program introduction video can be displayed as a banner display on the display screen of the viewing content.

[0057] The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that the plurality of program introduction videos can be displayed on the viewer terminal 3. For example, the introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that the plurality of program introduction videos can be sequentially displayed on the viewer terminal 3. The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that each of the plurality of program introduction videos can be displayed in a different area of ​​the display screen. The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that each of the plurality of program introduction videos can be displayed in a PinP format. The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that each of the plurality of program introduction videos can be displayed as a thumbnail image. The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that the plurality of program introduction videos can be displayed on a screen such as a list display for selecting video content to be viewed on the viewer terminal 3. In this case, the program introduction video may be a program introduction video based on live broadcast content that is not related to the viewing content. The introduction video distribution unit 113 may distribute to the viewer terminal 3 so that multiple program introduction videos based on the user information of the viewer of the viewer terminal 3 can be displayed. According to this example, the introduction video distribution unit 113 can distribute a program introduction video based on live broadcast content before the viewer of the viewer terminal 3 selects viewing content. When selecting content, the viewer can watch the live broadcast content that he or she is interested in based on the program introduction video. Therefore, the video distribution device 1 can efficiently appeal the live broadcast content to the viewer of the viewer terminal 3.

[0058] When a program introduction video of a live broadcast content related to the viewing content has not been created, the introduction video distribution unit 113 may distribute normal introduction data to the viewer terminal 3. When a program introduction video of a live broadcast content has not been created, this includes when no program introduction video is stored in the storage unit 13. The normal introduction data includes product introduction data and content introduction data based on video content of time-shift distribution.

[0059] The user information acquisition unit 114 acquires user information of the viewer from the viewer terminal 3 via the communication unit 12. The user information acquisition unit 114 acquires user information of the distributor from the distributor terminal 2 via the communication unit 12.

[0060] The moving image delivery image in which the program introduction moving image is displayed will now be described. Fig. 3 is a diagram showing an example of a moving image delivery image displayed on the viewer terminal 3.

The time information may include a countdown display indicating the remaining time of the program introduction video. The time information may include a display indicating the elapsed time of the program introduction video. Area A2 may be displayed in any display manner, such as text display, icon display, symbol display, etc., as long as the display indicates that the program introduction video is a program introduction video.

[0062] The input key B1 includes information for distributing live broadcast content related to the program introduction video. The input key B1 may include link information that allows access to the live broadcast content related to the program introduction video. The input key B1 may be a button for inputting a distribution instruction for distributing the live broadcast content related to the program introduction video. In FIG. 3, the input key B1 is a "details" button. The input key B1 may be displayed in any display mode such as text display, icon display, symbol display, etc. The distribution instruction for distributing the live broadcast content related to the program introduction video is an example of a selection operation of the program introduction video. For example, the user can view the live broadcast content related to the program introduction video by selecting the input key B1. Based on the selection operation of the input key B1 by the user, the video distribution device 1 may distribute the live broadcast content related to the program introduction video to the viewer terminal 3.

[0063] The input key B2 may display text information such as "Skip introduction". The input key B2 may be displayed in any display mode such as text display, icon display, symbol display, etc. The input key B2 may be a button for inputting a distribution instruction for distributing viewing content. For example, a user can force-terminate the program introduction video by selecting the input key B2. A user can view viewing content by selecting the input key B2. Based on the user's selection operation of the input key B2, the video distribution device 1 may terminate the distribution of the program introduction video. Based on the user's selection operation of the input key B2, the video distribution device 1 may distribute viewing content to the viewer terminal 3. The input key B2 may include a countdown display indicating the remaining time of the program introduction video. The video distribution device 1 may display the input key B2 at a predetermined timing. The predetermined timing is, for example, a timing at which the program introduction video can be forced to terminate. The predetermined timing is, for example, a predetermined time after the start of the program introduction video.

[0064] Although a display example on the viewer terminal 3 based on the program introduction video provided from the video distribution device 1 has been described with reference to FIG. 3, the display example on the viewer terminal 3 is not limited to this.

[0065] The operation of video distribution device 1 will now be described. The process procedure described below is merely an example, and each process may be changed as much as possible. Each process may be omitted or replaced depending on the embodiment, and new processes may be added.

[0066] FIG. 4 is a flowchart for explaining an example of an information processing operation for creating a program introduction video in the video distribution device 1 according to the embodiment. The following process is executed based on the start of distribution of live broadcast content.

[0067] The introductory video processing unit 112 judges whether or not a predetermined timing is satisfied (step S1). In one example, the predetermined timing is the start of distribution of live broadcast content. In another example, the predetermined timing is a predetermined time after the start of the live broadcast content. For example, the predetermined timing is 5 minutes after the start of the distribution of the live broadcast content. In yet another example, the predetermined timing is a predetermined time interval after the start of the live broadcast content. For example, the predetermined timing is every 10 minutes after the start of the distribution of the live broadcast content. In the following description, it is assumed that the predetermined timing is every 10 minutes after the start of the distribution of the live broadcast content. If the introductory video processing unit 112 judges that the predetermined timing is satisfied (step S1: YES), the process transitions from step S1 to step S2. If the introductory video processing unit 112 judges that the predetermined timing is not satisfied (step S1: NO), the process repeats step S1.

[0068] The introductory moving image processing unit 112 extracts content data from the live broadcast content when a predetermined timing is met (step S2). In one example, the introductory video processing unit 112 cuts out a predetermined amount of content data from the live broadcast content. For example, the introductory video processing unit 112 cuts out 30 seconds of content data from the live broadcast content every 10 minutes after the start of distribution of the live broadcast content. According to this example, the introductory video processing unit 112 can create a program introductory video in accordance with the progress of the live broadcast content. In another example, the introduction video processing unit 112 cuts out content data from the live broadcast content based on a predetermined condition. For example, the predetermined condition is a break in the sound of the live broadcast content, a break in a scene, or the like. In this case, the introduction video processing unit 112 cuts out content data from the live broadcast content based on the sound of the live broadcast content or the break in a scene. For example, the introduction video processing unit 112 may cut out content data from the live broadcast content at the timing when the sound of the live broadcast content switches. The timing when the sound switches includes the stopping of a speaker's speech, the interruption of speech, the end of speech, the start of speech by a different speaker, the insertion of sound effects, and the like. The introduction video processing unit 112 may cut out content data from the live broadcast content at the timing when a scene switches. The predetermined condition may be the excitement of the live broadcast content. The excitement of the live broadcast content may be, for example, the number of comments from viewers exceeding a predetermined number. The excitement of the live broadcast content may be the volume of the live broadcast content exceeding a predetermined value. The introductory moving image processing unit 112 may extract content data of the exciting part from the live broadcast content.

[0069] The introduction video processing unit 112 may extract content data including comments input from the viewer terminal 3 for the live broadcast content. The comments input from the viewer terminal 3 may be synthesized or superimposed on the live broadcast content by known technology. In this case, the introduction video processing unit 112 may extract content data in which the comments are synthesized or superimposed on the live broadcast content, or may synthesize or superimpose the comments on the extracted content data to create a program introduction video.

[0070] The introduction video processing unit 112 creates a program introduction video based on the cut-out content data (step S3). In step S3, for example, the introduction video processing unit 112 may edit the cut-out content data to create the program introduction video. The introduction video processing unit 112 adds information that allows the cut-out content data to be recognized as a program introduction video. For example, the introduction video processing unit 112 synthesizes a jingle or the like with the cut-out content data. The introduction video processing unit 112 may add information related to live broadcast content to the cut-out content data. The information related to the live broadcast content includes, for example, link information for distributing the live broadcast content. The information related to the live broadcast content may be information introducing the live broadcast content. The information introducing the live broadcast content includes, for example, "This kind of program is on," "This program is about XX," and the like.

[0071] The introductory video processing unit 112 stores the created program introduction video in the storage unit 13 (step S4). In step S4, for example, the introductory video processing unit 112 may store the program introduction video in the storage unit 13 every time the introductory video is created. The introductory video processing unit 112 may store a plurality of program introduction videos for the live broadcast content in the storage unit 13. The introductory video processing unit 112 may update the program introduction video every time the introductory video is created. The introductory video processing unit 112 may store the sequentially updated program introduction videos for the live broadcast content in the storage unit 13. The introductory video processing unit 112 may store time information when the program introduction video was created in association with the program introduction video.

[0072] FIG. 5 is a flowchart illustrating an example of an information processing operation for distributing a program introduction video in the video distribution device 1 according to the embodiment.

[0073] In the following process, it is assumed that a viewer at the viewer terminal 3 is viewing time-shifted video content. The following process is also applicable to live video content, still image data, etc. The viewer at the viewer terminal 3 selects the desired content as viewing content and starts viewing.

[0074] The content delivery unit 111 delivers content data to the viewer terminal 3 via the communication unit 12 (step S11). In step S11, for example, the content delivery unit 111 acquires a delivery request for viewing content from the viewer terminal 3. In response to the delivery request, the content delivery unit 111 delivers content data of the viewing content to the viewer terminal 3. The content data of the viewing content is also simply referred to as viewing content.

[0075] The introduction video distribution unit 113 judges whether the predetermined timing is satisfied (step S12). In a first example, the predetermined timing is before the start of distribution of the viewing content. Before the start of distribution of the viewing content, the distribution time of the viewing content or the elapsed time from the distribution of the viewing content is "0:00". In a second example, the predetermined timing is after a predetermined time has elapsed since the start of distribution of the viewing content. For example, the predetermined timing is 15 minutes after the start of distribution of the viewing content. In a third example, the predetermined timing is every fixed time after the start of distribution of the viewing content. For example, the predetermined timing is every 10 minutes after the start of distribution of the viewing content. In a fourth example, the predetermined timing is after the end of distribution of the viewing content. In the following example, the predetermined timing is every 10 minutes after the start of distribution of the viewing content.

[0076] If the introductory video distribution unit 113 determines that the predetermined timing is met (step S12: YES), the process transitions from step S12 to step S13. If the introductory video distribution unit 113 determines that the predetermined timing is not met (step S12: NO), the process ends.

[0077] The introduction video distribution unit 113 acquires a program introduction video based on live broadcast content related to the viewing content from the storage unit 13 at a predetermined timing (step S13). In step S13, for example, the introduction video distribution unit 113 acquires the latest program introduction video of the program introduction video based on live broadcast content related to the viewing content from the storage unit 13. Note that the introduction video distribution unit 113 may acquire all program introduction videos based on live broadcast content related to the viewing content. In this case, the introduction video distribution unit 113 may determine the program introduction video to be distributed based on time information, etc. Based on the time information, etc., the introduction video distribution unit 113 may determine the program introduction video having time information closest to the current time as the program introduction video to be distributed.

[0078] The introduction video distribution unit 113 distributes the acquired program introduction video to the viewer terminal 3 (step S14). In step S14, for example, the introduction video distribution unit 113 distributes the program introduction video to the viewer terminal 3 separately from the viewing content. Note that the introduction video distribution unit 113 may synthesize the program introduction video with the viewing content and distribute it to the viewer terminal 3. While the program introduction video is being distributed by the introduction video distribution unit 113, the content distribution unit 111 may stop distributing the viewing content. For example, the introduction video distribution unit 113 distributes the program introduction video created every 10 minutes after the start of distribution of the live broadcast content to the viewer terminal 3 every 10 minutes after the start of distribution of the viewing content, thereby sequentially distributing the program introduction video according to the progress of the live broadcast content to the viewer. According to this example, the video distribution device can distribute the live broadcast content to the viewer as the program introduction video in almost real time. Since the viewer can check the progress of the live broadcast content in the program introduction video, the viewer can decide whether or not to view the live broadcast content based on the progress of the live broadcast content.

[0079] The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that the program introduction video can be displayed on the viewer terminal 3 instead of the viewing content. The introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that the program introduction video can be displayed in switching with the display of the viewing content on the viewer terminal 3. The viewer terminal 3 displays the program introduction video instead of the viewing content.

[0080] In addition, when the live broadcast content related to the viewed content is not stored in the memory unit 13, the introduction video distribution unit 113 may distribute normal introduction data to the viewer terminal 3. When the live broadcast content related to the viewed content is not stored in the memory unit 13, this includes a case where the distribution of the live broadcast content related to the viewed content has not started. When the live broadcast content related to the viewed content is not stored in the memory unit 13, this includes a case where the distribution of the live broadcast content related to the viewed content has ended. When the live broadcast content related to the viewed content and normal introduction data are stored in the memory unit 13, the introduction video distribution unit 113 may distribute a program introduction video related to the live broadcast content to the viewer terminal 3 in priority to the normal introduction data.

[0081] In addition, when there are multiple live broadcast contents related to the viewing content, the introduction video distribution unit 113 may sequentially distribute program introduction videos related to the multiple live broadcast contents to the viewer terminal 3. For example, the introduction video distribution unit 113 may distribute a first program introduction video related to a first live broadcast content to the viewer terminal 3, and distribute a second program introduction video related to a second live broadcast content to the viewer terminal 3 following the first program introduction video. The introduction video distribution unit 113 may distribute program introduction videos related to multiple live broadcast contents to the viewer terminal 3 in parallel. For example, the introduction video distribution unit 113 may distribute the first program introduction video so that it can be displayed in a first display area of ​​the display area of ​​the viewer terminal 3, and distribute the second program introduction video so that it can be displayed in a second display area of ​​the display area of ​​the viewer terminal 3. The first display area and the second display area may be different display areas provided in the display area of ​​the viewer terminal 3. The first display area and the second display area may be areas in which an image can be displayed in PinP format. The first program introduction video and the second program introduction video may be displayed in the display area of ​​the viewer terminal 3 as thumbnail images.

[0082] The content distribution unit 111 determines whether or not a program introduction video selection operation has been performed by the viewer of the viewer terminal 3 (step S15). In step S15, for example, the content distribution unit 111 determines that a program introduction video selection operation has been performed when the viewer of the viewer terminal 3 selects information for distributing live broadcast content. For example, the content distribution unit 111 determines that a program introduction video selection operation has been performed when the user selects link information that allows access to live broadcast content that is to be displayed by being synthesized or superimposed on the program introduction video. In the example of FIG. 3, when the user wants to view live broadcast content related to the program introduction video, the user selects the "Details" button. In response to the user selecting the "Details" button, the content distribution unit 111 determines that a program introduction video selection operation has been performed.

[0083] If the content distribution unit 111 determines that a program introduction video selection operation has been performed (step S15: YES), the process transitions from step S15 to step S16. If the content distribution unit 111 determines that a program introduction video selection operation has not been performed (step S15: NO), the process transitions from step S15 to step S17. The determination as to whether a program introduction video selection operation has been performed may be performed by the introduction video distribution unit 113. In this case, the introduction video distribution unit 113 may output the determination result to the content distribution unit 111. The determination result may include an instruction to distribute the program introduction video. The determination as to whether a program introduction video selection operation has been performed may be performed by the viewer terminal 3. In this case, the viewer terminal 3 may output the determination result to the video distribution device 1. The determination result may include an instruction to distribute the program introduction video.

[0084] The content distribution unit 111 distributes live broadcast content related to the program introduction video to the viewer terminal 3 based on the selection operation of the program introduction video by the viewer of the viewer terminal 3 (step S16). In step S16, for example, the content distribution unit 111 distributes the live broadcast content to the viewer terminal 3 in real time according to the progress of the live broadcast content. The content distribution unit 111 may distribute the live broadcast content to the viewer terminal 3 as a time-shift distribution in which the live broadcast content is distributed from the beginning of the content. According to this example, the viewer can view the live broadcast content from the beginning regardless of the timing at which the viewer started viewing. If the predetermined timing in step S12 is before the start of the distribution of the viewing content, based on the selection operation of the program introduction video, the content distribution unit 111 distributes the live broadcast content to the viewer terminal 3 without distributing the viewing content.

[0085] The content distribution unit 111 determines whether the program introduction video has ended (step S17). In one example, the content distribution unit 111 determines that the program introduction video has ended based on the end of the playback time of the program introduction video. In another example, the content distribution unit 111 determines that the program introduction video has ended based on the viewer of the viewer terminal 3 forcibly terminating the playback of the program introduction video. In addition, when the playback time of the program introduction video has ended, the content distribution unit 111 may count up the number of views of the live broadcast content related to the program introduction video. For example, when the viewer of the viewer terminal 3 watches the program introduction video until the playback ends, the content distribution unit 111 increments the number of views of the live broadcast content related to the program introduction video by "1". In addition, the content distribution unit 111 may count up the number of views of the live broadcast content related to the program introduction video when the program introduction video is viewed by the viewer of the viewer terminal 3. For example, when the viewer of the viewer terminal 3 starts watching the program introduction video, the content distribution unit 111 increments the number of views of the live broadcast content related to the program introduction video by "1".

[0086] If the content distribution unit 111 determines that the program introduction video has ended (step S17: YES), the process ends. If the content distribution unit 111 determines that the program introduction video has not ended (step S17: NO), the process transitions from step S17 to step S15.

[0087] In addition, based on the fact that the program introduction video has ended, the content distribution unit 111 distributes the viewing content to the viewer terminal 3 in place of the program introduction video. The content distribution unit 111 may resume the distribution of the viewing content to the viewer terminal 3.

[0088] In addition, if the predetermined timing is every 10 minutes after the start of the viewing content distribution, the introduction video distribution unit 113 may distribute different program introduction videos of the same live broadcast content to the viewer terminal 3 at a timing (first timing) 10 minutes after the start of the viewing content distribution and a timing (second timing) 10 minutes after that. In this case, the program introduction video distributed at the first timing and the program introduction video distributed at the second timing include content data cut out at different timings of the live broadcast content. Therefore, the viewer of the viewer terminal 3 can watch the program introduction video cut out of the content at different timings of the same live broadcast content. For example, at the first timing, the introduction video distribution unit 113 distributes to the viewer terminal 3 a program introduction video including 30 seconds of content from the start of the same live broadcast content. At the second timing, the introduction video distribution unit 113 distributes to the viewer terminal 3 a program introduction video including 30 seconds of content 10 minutes after the start of the same live broadcast content. Therefore, the viewer of the viewer terminal 3 can watch different program introduction videos according to the progress of the same live broadcast content, and can know the progress of the live broadcast content. Also, the viewer of the viewer terminal 3 can know the timing of excitement according to the progress of the live broadcast content, and is more likely to become interested in the live broadcast content. The viewer of the viewer terminal 3 can switch from viewing the viewing content to the live broadcast content when he or she becomes interested.

[0089] The introduction video distribution unit 113 may distribute program introduction videos related to different live broadcast contents to the viewer terminal 3 at the first timing and the second timing. In this case, the program introduction video distributed at the first timing and the program introduction video distributed at the second timing include content data cut out from different live broadcast contents. Therefore, the viewer of the viewer terminal 3 can view the program introduction video related to the different live broadcast contents while viewing the viewing content. For example, the introduction video distribution unit 113 distributes to the viewer terminal 3 at the first timing a program introduction video including a 30-second content from the start of the first live broadcast content associated with the viewing content. The introduction video distribution unit 113 distributes to the viewer terminal 3 at the second timing a program introduction video including a 30-second content from the start of the second live broadcast content associated with the viewing content. The introduction video distribution unit 113 may distribute to the viewer terminal 3 at the second timing a program introduction video including a 30-second content 10 minutes after the start of the second live broadcast content associated with the viewing content. Therefore, a viewer of the viewer terminal 3 can watch a program introduction video of a different live broadcast content while watching the same viewing content. Since the viewer of the viewer terminal 3 can watch program introduction videos of multiple live broadcast contents associated with the viewing content, the viewer is more likely to become interested in the live broadcast content. When the viewer of the viewer terminal 3 watches a program introduction video of the live broadcast content that interests him / her, he / she can switch from viewing the viewing content to the live broadcast content.

[0090] In addition, in step S14, the introduction video distribution unit 113 may distribute the program introduction video to the viewer terminal 3 so that the program introduction video can be displayed in PinP format or the like in parallel with the display of the viewing content. In this case, in step S14, the content distribution unit continues distribution of the viewing content to the viewer terminal 3.

[0091] In addition, the introduction video distribution unit 113 may distribute information about the live broadcast content related to the program introduction video to the viewer terminal 3 so as to display it as a banner on the display screen of the viewing content after the program introduction video ends. In this case, the information about the live broadcast content related to the program introduction video may be link information that enables access to the live broadcast content. According to this example, the introduction video distribution unit 113 can distribute information about the live broadcast content to the viewer terminal 3 so that the viewer can access the program introduction video at any timing while watching the viewing content. The viewer can start watching the live broadcast content at any timing.

[0092] In addition, when the introduction video distribution unit 113 determines the related live broadcast content based on the user information of the viewer of the viewer terminal 3, the program introduction video may be distributed to the viewer terminal 3 as follows. In one example, when the viewer of the viewer terminal 3 sequentially watches a plurality of different viewing contents, a program introduction video based on the same related live broadcast A may be distributed while the viewer is watching the plurality of viewing contents. In this example, the introduction video distribution unit 113 may sequentially distribute program introduction videos created based on content data of the same related live broadcast A at different timings. According to this example, the introduction video distribution unit 113 can view the progress of the related live broadcast A as a program introduction video while the viewer of the viewer terminal 3 is watching a plurality of different viewing contents. Therefore, even if the viewer is watching different viewing contents, the viewer can watch the related live broadcast A at the timing when he or she becomes interested in the related live broadcast A. In another example, while the viewer of the viewer terminal 3 sequentially watches a plurality of different viewing contents, program introduction videos based on different related live broadcasts A and B may be distributed. In this example, the introduction video distribution unit 113 may sequentially distribute a program introduction video based on the related live broadcast A and a program introduction video based on the related live broadcast B. The introduction video distribution unit 113 may distribute a program introduction video based on related live broadcast A while related live broadcast A is being distributed, and distribute a program introduction video based on related live broadcast B while related live broadcast B is being distributed after the distribution of related live broadcast A ends. According to this example, the introduction video distribution unit 113 allows a viewer of the viewer terminal 3 to watch multiple related live broadcasts as program introduction videos while watching multiple different viewing contents. Therefore, the viewer can watch program introduction videos of different related live broadcasts, making it easier to find a live broadcast that interests him / her.

[0093] In addition, when the introductory video distribution unit 113 distributes a program introductory video based on the same related live broadcast to the same viewer terminal 3 multiple times, the introductory video distribution unit 113 may add the past related live broadcast to the program introductory video created from the second time onward. A digest movie including the content data may also be distributed.

[0094] In addition, instead of the program introduction video, the introduction video distribution unit 113 may distribute live broadcast content for a predetermined time to the viewer terminal 3. In this case, the introduction video distribution unit 113 may distribute the live broadcast content to the viewer terminal 3 instead of the viewing content according to the progress of the live broadcast content.

[0095] As described above, according to this embodiment, the video distribution device acquires live broadcast content from a distributor terminal, and an introduction video processing unit creates a program introduction video based on the live broadcast content, and distributes the program introduction video to a viewer terminal of a viewer who is watching selected content different from the live broadcast content. This allows the video distribution device to introduce the contents of the live broadcast content currently being broadcast to viewers who are watching selected content different from the live broadcast content. In this way, the video distribution device can effectively appeal to viewers who are not watching the live broadcast content, such as viewers who are unaware of the live broadcast content, by using the live broadcast content currently being broadcast.

[0096] According to this embodiment, the video distribution device distributes a program introduction video based on live broadcast content related to the content to a viewer terminal. Therefore, the video distribution device can introduce the details of the live broadcast content related to the content in which the viewer is interested. This makes it easier for the viewer to become interested in the live broadcast content related to the program introduction video. In this way, the video distribution device can effectively appeal to the viewer the live broadcast content currently being broadcast.

[0097] According to this embodiment, the video distribution device transmits information for distributing live broadcast content to the viewer terminal. Therefore, viewers are given an opportunity to watch the live broadcast content based on the program introduction video. The video distribution device can induce viewers who have become interested in the live broadcast content through the program introduction video to watch the live broadcast content. In this way, the video distribution device can effectively appeal to viewers the live broadcast content that is currently being broadcast.

[0098] According to this embodiment, the video distribution device distributes live broadcast content based on the viewer's selection operation of information for distributing live broadcast content. Therefore, the viewer can easily watch live broadcast content that interests him / her. Furthermore, the viewer can check the live broadcast content before watching it by using the program introduction video. Therefore, the viewer can start watching the live broadcast content without being disappointed by the impression he / she got from the program introduction video. In this way, the video distribution device can effectively appeal to the viewer the live broadcast content that is currently being broadcast.

[0099] According to this embodiment, the video distribution device creates a program introduction video at a predetermined time interval. Therefore, the video distribution device can create a program introduction video according to the progress of the live broadcast content. This allows the video distribution device to distribute the live broadcast content to viewers as a program introduction video almost in real time. Since the viewers can check the progress of the live broadcast content in the program introduction video, they can decide whether or not to watch the live broadcast content based on the progress of the live broadcast content. In this way, the video distribution device can effectively appeal to viewers the live broadcast content that is currently being broadcast.

[0100] According to this embodiment, the video distribution device creates a program introduction video based on a predetermined condition for the live broadcast content. For example, the video distribution device can create a program introduction video that is easy for viewers to watch by creating the live broadcast content based on audio and scene breaks. Furthermore, the video distribution device can create a program introduction video that is more likely to interest viewers by creating the live broadcast content based on the excitement of the content, etc. This allows the video distribution device to more effectively appeal to viewers about the appeal of the live broadcast content.

[0101] According to the present embodiment, the video distribution device distributes a program introduction video to a viewer terminal at a predetermined timing. For example, the video distribution device can distribute the program introduction video before and after the distribution of the viewing content. Therefore, the video distribution device can distribute the program introduction video at a timing when the viewer can easily switch the viewing from the viewing content to the live broadcast content. This allows the video distribution device to more effectively appeal to the viewer the live broadcast content, and effectively encourage the viewer to watch the live broadcast content. Furthermore, the video distribution device can distribute the program introduction video at regular time intervals. Therefore, the video distribution device can sequentially distribute the program introduction video according to the progress of the live broadcast content to the viewer. This allows the video distribution device to distribute the live broadcast content to the viewer as the program introduction video in almost real time. Since the viewer can check the progress of the live broadcast content in the program introduction video, the viewer can decide whether or not to watch the live broadcast content based on the progress of the live broadcast content. In this way, the video distribution device can more effectively appeal to the viewer the live broadcast content being broadcast, and effectively encourage the viewer to watch the live broadcast content.

[0102] According to this embodiment, the video distribution device distributes live broadcast content to the viewer terminal from the beginning of the content. Therefore, the viewer can watch the live broadcast content from the beginning regardless of the timing at which the viewer started watching the content. In this way, the video distribution device can effectively encourage the viewer to watch the live broadcast content by delivering the live broadcast content according to the viewer's viewing needs.

[0103] According to this embodiment, the video distribution device distributes the program introduction video to the viewer terminal so that the program introduction video can be displayed on the viewer terminal while the viewer is viewing the content. Therefore, the viewer can check the progress of the live broadcast content in the program introduction video while viewing the viewing content. This allows the viewer to start viewing the live broadcast content at any timing. In this way, the video distribution device can more effectively appeal to the viewer the live broadcast content that is currently being broadcast, and can effectively encourage the viewer to view the live broadcast content.
