Abstract: It is possible to accurately and securely execute conversion from an MPEG-2TS format to an MP4 format. 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.

Abstract: To enable MMT format data to be recorded as BDAV format data in a medium, and a list of video-recorded contents to be displayed and reproduced by an application for BDAV. Data to be recorded in a playlist or clip information file defined in a BDAV format is extracted from MMT format data input on a broadcast wave or the like thereby to generate a data file thereof. For example, data applied to display a list of video-recorded contents is extracted from MMT-SI or TLV-SI in the MMT format data and recorded in the playlist or clip information file.
