Abstract: A compilation system (101) includes: a plurality of viewing terminals (104) with which a plurality of viewers respectively views a video; and a compilation server (105). Each terminal (104) of the viewing terminals, using at least one processor of one or more processors in the terminal (104), enables a viewer using the terminal (104) to view one of one or more contents associated with the video in advance while the video is being played in the terminal (104). The compilation server (105), using at least one processor of one or more processors in the compilation server (105), collects whether either one of one or more contents is being browsed while the video is being played in each terminal (104) of the viewing terminals. The compilation server (105) compiles a trend in the numbers of viewers, among the viewers, who have been browsing respective content of one or more contents at certain playback times of the video.

Abstract: A generator (251) generates a viewer video in which an object is synthesized at a predetermined synthesis position in a live video captured by an imager (210). Additionally, the generator (251) generates a streamer video that is a video obtained by synthesizing the object in a mirror image video in which the live video is inverted, and in which the object is synthesized at a mirror image position relative to the synthesis position. A streaming unit (252) sends the viewer video generated by the generator (251) to a streaming server for streaming to the viewer terminal. A display 260) displays the streamer video generated by the generator (251).

Abstract: A distribution management system (101) plays, on a screen, a video (A) in which a plurality of topics (a1, a2, . . . ) is sequentially covered, determines a topic (a1) currently being covered on the screen on which the video (A) is being played, identifies a list (L1) of recommendation videos (X1) in which a topic related to the determined topic (a1) is covered, and provides the identified list (L1) via the screen.

Abstract: The generator (141) generates a group (for example, a group chat) for viewers of a video introducing a product to interact with each other on social media (for example, a messenger service). The detector (142) detects a viewer who has viewed the video introducing the product and purchased the product. The registrar (145) then registers the viewer detected by the detector (142) to the group generated by the generator (141).

Abstract: A receiver (120) receives, from each of a plurality of terminals being playing a distributed live video, a piece of access information sent in response to an operation on one of a plurality of objects respectively associated with a plurality of products presented in the live video. A collector (142) collects video identification information identifying the live video, product identification information identifying a product associated with the operated object, and time information indicating a playback time of the live video at a point of time at which the operation is performed, the video identification information, the product identification information, and the time information being included in each of the received pieces of access information. An estimator (143) estimates, based on the collected video identification information, product identification information, and time information, a time period during which each of the plurality of products was presented in the live video.

Abstract: A collector (101) collects behaviors of a plurality of viewers viewing a live streaming video from a plurality of viewer terminals (300) respectively used by the plurality of viewers. The allocator (103) allocates, to each viewer of the plurality of viewers, another viewer specified as a referent from among the plurality of viewers based on the collected behaviors. The generator (104) generates display control information for each viewer based on a behavior of the viewer and a behavior of the referent allocated to the viewer among the collected behaviors. The transmitter (105) transmits the generated display control information to a viewer terminal (300) used by each viewer.

Abstract: A distribution controller (141) distributes a live video provided from a streamer to a viewer terminal having a comment area, the comment area allowing a predetermined number of comments to be displayed. A receiver (120) receives a comment posted from the viewer terminal during distribution of the live video. A sender (110) sends a comment that the receiver (120) received to the viewer terminal to cause the comment to be added to the comment area in a last-in-first-out manner. An identifier (144) identifies a comment to which the streamer reacted in the live video being distributed by, every time the streamer speaks, comparing a speech text, the speech text being acquired by subjecting speech of the streamer to speech recognition, with respective comments currently being displayed in the comment area. A display controller (145) controls display of the identified comment.

Abstract: A distribution controller (141) distributes a live video provided from a streamer to a plurality of terminals each of which has a comment area, the comment area allowing a predetermined number of comments to be displayed. A receiver (120) receives a comment posted from, among the plurality of terminals, a viewer terminal used by a viewer during distribution of the live video. A sender (110) sends a comment that the receiver (120) received to the plurality of terminals to cause the comment to be added to the comment areas in a last-in-first-out manner. An identifier (144) identifies, among respective comments currently being displayed in the comment area, a comment to which the streamer reacted. A setter (541) sets a chapter to divide the live video, based on a relative time in the live video corresponding to a time at which the identified comment is received.

Abstract: A display (101) displays a foreground window in which a video is played on a screen and so as to hide a portion of a background window in which content including a user-operable interactive element is provided. A detector (102) detects hiding of the interactive element by the foreground window. When the hiding is detected, a changer (103) changes at least either a position or a size of the foreground window so that a portion or an entirety of a hidden portion of the interactive element is no longer hidden.

Abstract: A distribution management system (101) plays, on a screen, a video (A) in which a plurality of topics (a1, a2, . . . ) is sequentially covered, determines a topic (a1) currently being covered on the screen on which the video (A) is being played, identifies a list (L1) of recommendation videos (X1) in which a topic related to the determined topic (a1) is covered, and provides the identified list (L1) via the screen.

Abstract: A streamer terminal (102) makes (122), upon receiving text, the text appear in a screen, determines (123) whether a streamer pays attention to the text, until the text exits from the screen, and executes (124) a predetermined attention process on text-of-attention that the streamer is determined to pay attention to. Each terminal (103) of viewer terminals classified into any one of groups transmits (132) text accepted from a viewer using each terminal to the streamer terminal (102) and another viewing terminals (103) belonging to an identical group, receives (133) text transmitted from another viewer terminal belonging to the identical group, and makes (134) the text appear in a screen. The streamer terminal (102) transmits (124) the text-of-attention to viewer terminals (103) classified in another group, and each terminal of the viewer terminals (103), upon receiving the text-of-attention, makes the text-of-attention appear in the screen.

Abstract: In an information processing device to streaming-distribute a video, based on a distance image in which a streamer is captured, an acquirer (101) acquires a depth distribution in the distance image. A determiner (102) determines a threshold value, based on the acquired depth distribution. An specifier (103) specifies, in the distance image, a distant region where depth is greater than the threshold value and a near region where depth is less than the threshold value. A provider (104) provides, in conjunction with the video, to a viewer terminal (300) to which the video is to be streaming-distributed, control information to set the distant region as a background, set the near region as a foreground, superimpose provided information over the background, and superimpose the foreground over the background over which the provided information is superimposed.
