1. A content supply apparatus for multicasting a stream of fragments of a content using a file over unidirectional transport F L UTE protocol, comprising:

  • a clip stream generation unit configured to sequentially generate the clip stream including a group of pictures, GOP, unit that can be randomly accessed, each of the GOPs being randomly accessible, based on source data of the content captured in real time; and

    a transmission unit configured to subdivide the sequentially generated clip stream into second data units having a period shorter than the GOP units, thereby sequentially generating file transmission units transmitted in F L UTE in units of the second data units, GOP being subdivided into a plurality of the file transmission units transmitted in F L UTE, and sequentially transmitting the sequentially generated file transmission units via F L UTE,wherein the file transfer unit contains a decoding timing for a first sample in the file transfer unit,wherein the transfer unit generates the file transfer unit including moof in which a version attribute is added to the second data unit of the GOP unit of the clip stream and mdat in which data of the second data unit is stored.
