Abstract

A broadcasting system comprises a transmission apparatus, which multiplexes stream-format data based on a stream transmission protocol and file-format data based on a file transmission protocol with each other and sends them as a single stream, and receiving apparatuses which receive and temporarily accumulate stream-format data and file-format data which are sent as they are multiplexed with each other, and stream-format data and file-format data are temporarily accumulated as they directly are in the form of a single stream, all or some of file-format data are reproduced later at predetermined timing and accumulated once again as a file.
