Abstract: An encoding parameter deriving apparatus for improving video delivery quality is provided. The encoding parameter deriving includes: a relationship deriving unit that calculates a value of an index indicating a quality of experience of a viewer for each of a plurality of encoded videos generated by encoding an original video by a plurality of combinations of values of encoding parameters, and derives a relationship between the values of the encoding parameters and the values of the index; and a possibility deriving unit that derives a plurality of possibilities for a combination of values of the encoding parameters to be used for encoding the original video, based on the relationship.

Abstract: An engagement estimation apparatus includes an acquisition unit configured to acquire, for each measurement section after an instruction of a start of a view of an video delivered through a network, any of a parameter related to a coding quality of the video in the measurement section and a parameter related to a viewing state of the video in the measurement section, and an estimation unit configured to calculate an estimation value of an index for evaluation of engagement for each measurement section based on a parameter acquired by the acquisition unit in the measurement section. Thus, it is possible to estimate engagement based on parameters that can be observed in a terminal.

Abstract: A viewing completion rate estimation apparatus includes a processor configured to calculate an estimated value of a viewing completion rate per unit time based on an estimated value of video quality and a characteristic that the viewing completion rate decreases with a decrease in the video quality; and estimate a viewing completion rate for a video content length based on the estimated value of the viewing completion rate per unit time.

Abstract: An engagement estimation device includes an engagement estimation unit which calculates an estimated value of an index for assessing engagement of a viewer of a video at a certain elapsed time from a start of playback of the video distributed via a network, and the engagement estimation unit calculates the estimated value such that, in the case where the playback of the video is stopped at the certain elapsed time, the stop of the playback influences the estimated value more significantly than in the case where the playback of the video is not stopped at the certain elapsed time.

Abstract: Injectable compositions and methods of treating skin can help improve hydration, elasticity and/or texture of the skin. The compositions can be based on crosslinked hyaluronic acid matrices made with low molecular weight hyaluronic acids.

Abstract: An engagement estimation apparatus includes an acquisition unit configured to acquire, when stalling of a video delivered through a network occurs, a stalling position at occurrence of the stalling and a duration of the stalling, and an estimation unit configured to calculate an estimation value of an index for evaluation of engagement based on a property that the number of exited viewers increases as the stalling position is lengthened and as the duration increases. Thus, engagement can be estimated based on a parameter that can be observed in a terminal.
