Provided are a method and apparatus for controlling a plurality of data processing modules that process data independently and output the processed data. A method of controlling a first data processing module and a second data processing module that process data independently and synchronize and output the processed data, the method including acquiring first data output rate information representing a current data output rate of the first data processing module, acquiring second data output rate information representing a current data output rate of the second data processing module, and adjusting a data output rate of at least one of the first data processing module and the second data processing module, on the basis of the first data output rate information and the second data output rate information.
