A multiplexing apparatus/method is characterized by inputting a plurality of data streams with which identification information of data is multiplexed, extracting the identification information multiplexed with the plurality of input data streams from the plurality of input data streams, detecting pieces of identification information, of the extracted identification information extracted, which are redundant among the respective data streams, replacing the detected identification information with new identification information, and multiplexing the plurality of data streams obtained by replacement.
