To provide a media data processing system that can suppress a decrease in a request processing rate while suppressing an increase in response time in media data recognition processing where it is difficult to properly estimate the load. A first load estimation unitestimates range of processing load of media data recognition processing based on header information of media data. A determination unitdetermines whether to allow or disallow execution of the media data recognition processing, or to estimate the processing load, based on the range of the processing load. A second load estimation unitestimates the processing load of the media data recognition processing based on content of the media data when it is determined to estimate the processing load. The determination unitdetermines whether to allow or disallow the execution of the media data recognition processing based on the processing load.
