Abstract

An MXF parser thread 43 parses data MXF_D, being, mixed together, a plurality of video data PIC, a plurality of audio data SOU, and system data SYS. Then, it generates video file attribute data VFPD concerning the video based on the parsed system data and metadata META and generates video file data VF including the video file attribute data VFPD and the parsed plurality of video data PIC (VIDEO). Further, the audio file data AF is generated too in the same way.
