A display control server device for controlling the displaying of video content on a display screen of a reception device together with additional information associated with the video content by using a fingerprint, the display control server device comprising: a content receiver that receives the video content; a fingerprint creator comprising a region specification section that specifies, in each of a plurality of frames included in the video content, a first region and a second region included in a region excluding the first region in each of the frames; a region-of-interest estimation section that specifies, in each of the plurality of frames, either one of the first region and the second region as a region of interest and the other region as a region of non-interest based on a positional relationship between the first region and the second region; a position decision section that defines, as a position at which the additional information is to be displayed, a position included commonly in the respective regions of non-interest of the plurality of frames such that the position is a fixed position in the screen that does not move in the screen during displaying the plurality of frames; and wherein the fingerprint creator creates the fingerprint corresponding to the video content; and a collator that collates the fingerprint, which is created by the fingerprint creator, with a fingerprint received from the reception device; wherein the collator transmits, when the fingerprint, which is created by the fingerprint creator, coincides with the fingerprint received from the reception device, to the reception device the position at which the additional information is to be displayed. a content receiver that receives the video content; a fingerprint creator comprising a region specification section that specifies, in each of a plurality of frames included in the video content, a first region and a second region included in a region excluding the first region in each of the frames; a region-of-interest estimation section that specifies, in each of the plurality of frames, either one of the first region and the second region as a region of interest and the other region as a region of non-interest based on a positional relationship between the first region and the second region; a position decision section that defines, as a position at which the additional information is to be displayed, a position included commonly in the respective regions of non-interest of the plurality of frames such that the position is a fixed position in the screen that does not move in the screen during displaying the plurality of frames; and a region specification section that specifies, in each of a plurality of frames included in the video content, a first region and a second region included in a region excluding the first region in each of the frames; a region-of-interest estimation section that specifies, in each of the plurality of frames, either one of the first region and the second region as a region of interest and the other region as a region of non-interest based on a positional relationship between the first region and the second region; a position decision section that defines, as a position at which the additional information is to be displayed, a position included commonly in the respective regions of non-interest of the plurality of frames such that the position is a fixed position in the screen that does not move in the screen during displaying the plurality of frames; and wherein the fingerprint creator creates the fingerprint corresponding to the video content; and a collator that collates the fingerprint, which is created by the fingerprint creator, with a fingerprint received from the reception device; wherein the collator transmits, when the fingerprint, which is created by the fingerprint creator, coincides with the fingerprint received from the reception device, to the reception device the position at which the additional information is to be displayed.
