The related information storage unit 210 associates and stores the parameter set applied to the content when the content receiver received the content and the receiver related information of the receiver. The related information storage unit 210 stores the recipient-related information acquired by the related information acquisition unit 208 while the content to which the parameter set is applied by the output control unit 206 is being output by the content output device 300, in correspondence with the parameter set. You can attach it and store it.

The characteristic identification unit 212 identifies the characteristics of the receiver corresponding to each of the parameter sets based on the plurality of receiver-related information stored in association with the related information storage unit 210 for each of the parameter sets. . For example, when content to which a certain parameter set is applied attracts more attention from women in their 40s, the feature identification unit 212 identifies women in their 40s as the features of the recipient corresponding to the parameter set. The feature identification unit 212 may determine that the degree of attention is higher as the number of recipients to which attention is paid increases. Also, the feature identification unit 212 may determine that the longer the browsing time is, the higher the degree of attention is.

The feature identification unit 212 may determine the degree of attention in two stages. For example, the feature identifying unit 212 determines the degree of attention from the viewpoint of eye-catching (sometimes referred to as a first degree of attention) and the degree of attention from the viewpoint of whether to look closely (a second degree of attention). It may be described as the degree of attention.) is determined. The feature identifying unit 212 determines a first degree of attention based on the number of persons 20 who paid attention to the content, and determines a second degree of attention based on the browsing time of the content. For example, for a certain parameter set, a man in his 20s has a high first degree of attention and a low second degree of attention, and a woman in her 40s has a high first degree of attention and a low second degree of attention. If both degrees are high, it can be determined that the parameter set is more suitable for women in their 40s than for men in their 20s.

It may be determined whether the degree of attention given by the target is increasing or decreasing. Then, when the degree of attention by the target is increasing, the output control unit 206 changes other parameters while maintaining the change of the parameter. When the degree of attention by the target is decreasing, the output control unit 206 undoes the parameter change and changes other parameters. By repeating this, it is possible to optimize the parameter set determined by the parameter set determination unit 222 so as to better match the target.

If the content is audio content, the parameter set may include volume parameters. A parameter set may include an interval parameter. The parameter set may include timbre parameters. A parameter set may include speaker parameters.
