A data converting unit that executes format conversion from an MPEG-2TS format to an MP4 format sorts out TS packets storing video data from MPEG-2TS format data, selects a TS packet having a start code (SC) at the top of a payload on the basis of header information of the sorted out TS packets, and extracts payload configuration data other than the start code (SC) and sets the payload configuration data as configuration data of MP4 format data. The data converting unit determines, on the basis of, for example, a value of a transport priority set in a header of the TS packet, whether or not the TS packet is a TS packet in which a start code (SC) is set in a top region of a payload.
