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.
Claims12
An engagement estimation apparatus comprising:
- an acquisition unit, including one or more processors, configured to acquire, for each of measurement sections 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, wherein the acquisition unit is configured to acquire an initial loading delay;
- and
- an estimation unit, including one or more processors, configured to calculate an estimation value of an index for evaluation of engagement for each of the measurement sections based on a parameter acquired by the acquisition unit in the measurement section, wherein the estimation unit is configured to calculate the estimation value based on a mathematical model with a property that a number of existed viewers increases as the initial loading delay increases.
An engagement estimation method including, at a computer:
- an acquisition procedure of acquiring, for each of measurement sections 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, wherein the acquisition procedure comprises acquiring an initial loading delay;
- and
- an estimation procedure of calculating an estimation value of an index for evaluation of engagement for each of the measurement sections based on a parameter acquired by the acquiring in the measurement section, wherein the estimation procedure comprises calculating the estimation value based on a mathematical model with a property that a number of exited viewers increases as the initial loading delay increases.
A non-transitory computer readable medium storing one or more instructions configured to cause a computer to execute:
- an acquisition procedure of acquiring, for each of measurement sections 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, wherein the acquisition procedure comprises acquiring an initial loading delay;
- and
- an estimation procedure of calculating an estimation value of an index for evaluation of engagement for each of the measurement sections based on a parameter acquired by the acquiring in the measurement section, wherein the estimation procedure comprises calculating the estimation value based on a mathematical model with a property that a number of exited viewers increases as the initial loading delay increases.
