An information processing device includes a characteristics information storing unit for storing analysis characteristics information representing performance of each analysis method, and media characteristics information representing performance of each method of input of media data. The device includes a QoS calculating unit for calculating response performance and analysis accuracy when executing an analysis process in the media analysis system by preset media data input method and analysis method, based on the stored analysis characteristics information and media characteristics information. The device includes a QoS controlling unit for, in a case that at least one of the calculated response performance and analysis accuracy does not satisfy a preset target value, changing at least one of the preset media data input method and analysis method, based on the stored analysis characteristics information and media characteristics information.
