The bookmark management module manages a first type bookmark whose status is not changed by viewing of the video and a second type bookmark whose status is changeable after the viewing of the video. The control module generates screen data that enables one of the first type bookmark and the second type bookmark to be selected with regard to the video stored in the library, transmits the generated screen data to the one of the receiving terminals, and sets one of the first type bookmark and the second type bookmark, which is selected by a user using the one of the receiving terminals, for the video and record the one of the first type bookmark and the second type bookmark in the bookmark management module. ## Claims ### Claim 1 A video distribution system for distributing a video to a plurality of kinds of receiving terminals, the video distribution system comprising: a video distribution module for distributing video data stored in a library; a control module for generating screen data for displaying a list of the videos to be distributed to one of the receiving terminals; and a bookmark management module for managing information set for the video, wherein: the bookmark management module manages a first type bookmark whose status is not changed by viewing of the video and a second type bookmark whose status is changeable after the viewing of the video; and the control module is configured to: generate screen data that enables one of the first type bookmark and the second type bookmark to be selected with regard to the video stored in the library; transmit the generated screen data to the one of the receiving terminals; and set one of the first type bookmark and the second type bookmark, which is selected by a user using the one of the receiving terminals, for the video and record the one of the first type bookmark and the second type bookmark in the bookmark management module. ### Claim 2 (depends on 1) The video distribution system according to claim 1, wherein the control module is further configured to generate the screen data in which the information on the video for which the second type bookmark is set is positioned in a higher level than the information on the video for which the first type bookmark is set in a case where the user requests display of bookmarks on a first terminal that satisfies a predetermined condition among the plurality of kinds of the receiving terminals. ### Claim 3 (depends on 1) The video distribution system according to claim 1, wherein the control module is further configured to erase the second type bookmark set for the video after the user has viewed on a first terminal the video for which the second type bookmark is set. ### Claim 4 (depends on 3) The video distribution system according to claim 3, wherein the control module is further configured to: generate screen data that enables selection of one of erasing of the second type bookmark set for the video and changing of the second type bookmark to the first type bookmark after the user has viewed on the first terminal the video for which the second type bookmark is set; and erase the second type bookmark when the erasing of the second type bookmark is selected. ### Claim 5 An information providing device for providing information on a video to be distributed to a plurality of kinds of receiving terminals, the information providing device comprising: a video distribution module for distributing video data stored in a library; a control module for generating screen data for displaying a list of the videos to be distributed to one of the receiving terminals; and a bookmark management module for managing information set for the video, wherein: the bookmark management module manages a first type bookmark whose status is not changed by viewing of the video and a second type bookmark whose status is changeable after the viewing of the video; and the control module includes: a module for generating screen data that enables one of the first type bookmark and the second type bookmark to be selected with regard to the video stored in the library; a module for transmitting the generated screen data to the one of the receiving terminals; and a module for setting one of the first type bookmark and the second type bookmark, which is selected by a user using the one of the receiving terminals, for the video and recording the one of the first type bookmark and the second type bookmark in the bookmark management module. ### Claim 6 (depends on 5) The information providing device according to claim 5, wherein the control module further includes a module for generating the screen data in which the information on the video for which the second type bookmark is set is positioned in a higher level than the information on the video for which the first type bookmark is set in a case where the user requests display of bookmarks on a first terminal that satisfies a predetermined condition among the plurality of kinds of the receiving terminals. ### Claim 7 (depends on 5) The information providing device according to claim 5, wherein the control module further includes a module for erasing the second type bookmark set for the video after the user has viewed on a first terminal the video for which the second type bookmark is set. ### Claim 8 (depends on 7) The information providing device according to claim 7, wherein: the control module further includes a module for generating screen data that enables selection of one of erasing of the second type bookmark set for the video and changing of the second type bookmark to the first type bookmark after the user has viewed on the first terminal the video for which the second type bookmark is set; and the control module erases the second type bookmark when the erasing of the second type bookmark is selected. ### Claim 9 A video information providing method for use in a video distribution system for distributing a video to receiving terminals of a plurality of kinds, the video distribution system including a video distribution module for distributing video data stored in a library, a control module for generating screen data for displaying a list of the videos to be distributed to one of the receiving terminals, and a bookmark management module for retaining information set for the video, the bookmark management module managing a first type bookmark whose status is not changed by viewing of the video and a second type bookmark whose status is changeable after the viewing of the video, the video information providing method including the steps of: generating screen data that enables one of the first type bookmark and the second type bookmark to be selected with regard to the video stored in the library; transmitting the generated screen data to the one of the receiving terminals; and setting one of the first type bookmark and the second type bookmark, which is selected by a user using the one of the receiving terminals, for the video and recording the one of the first type bookmark and the second type bookmark in the bookmark management module. ### Claim 10 (depends on 9) The video information providing method according to claim 9, further including the step of generating the screen data in which the information on the video for which the second type bookmark is set is positioned in a higher level than the information on the video for which the first type bookmark is set in a case where the user requests display of bookmarks on a first terminal that satisfies a predetermined condition among the plurality of kinds of the receiving terminals. ### Claim 11 (depends on 9) The video information providing method according to claim 9, further including the step of erasing the second type bookmark set for the video after the user has viewed on a first terminal the video for which the second type bookmark is set. ### Claim 12 (depends on 11) The video information providing method according to claim 11, further including the steps of: generating screen data that enables selection of one of erasing of the second type bookmark set for the video and changing of the second type bookmark to the first type bookmark after the user has viewed on the first terminal the video for which the second type bookmark is set; and erasing the second type bookmark when the erasing of the second type bookmark is selected.
