Devices connected to a network are caused to conduct transcoding including combination of various coding schemes. A transcoding system includes (information processing) apparatuses, such as STBs, each including a memory unit and a processing unit, and converts a coding scheme of digital contents. The memory unit stores management information acquired from different apparatuses. The management information concerns conversion functions of coding schemes of digital contents concerning the apparatuses, and is information concerning demultiplexing, decoding, encoding and multiplexing. The processing unit determines different apparatuses capable of transcoding digital contents by referring to the management information, and transfers contents data and information indicating processing contents to the different apparatuses, which includes a format conversion unit to execute transcoding according to processing contents sent from the processing unit in an apparatus. Contents subjected to code conversion in the format conversion unit are transmitted to a request source, such as a portable telephone.
