METHOD AND APPARATUS FOR GENERATING, PLAYING FILE

摘要

The present invention relates to a method and an apparatus for generating and playing files related to the media data which is suitable for the transmission and storage of media data and a streaming environment. The present invention relates to a method for describing continuous time information of a sample indicating one frame unit in a total structure of a new file format which is suitable for the transmission and storage of media data proposed in MPEG based on ISO base media file format and a streaming environment; a method for describing time scale information; a method for describing information such as a sample initial number, pattern offset, start time, continuous time, a data reference index, a coding type index; and a method for describing the list information of the corresponding groups by grouping tracks and items. [Reference numerals] (1610) Receiving a media segment file; (1620) Storing a media segment file in a storage unit; (1630) Parsing attribute information related to a media segment file; (1640) Existence or absence of group list information; (1650) Selectively parsing the item attribute information and track of a corresponding group provided through group list information among tracks and items within a media segment file; (1660) Parsing item attribute information and all tracks within a media segment file; (1670) Restoring or reproducing media data using parsed data; (AA) START; (BB) END
