Abstract

The present invention relates to a method and an apparatus for generating a duplication management file. The present invention provides a method for generating a duplication management file, comprising the steps of: parsing a content packet contained in stream, and a program information packet related to the content packet; generating header information using the program information packet; and generating a duplication management file comprising the content packet and the header information, and thus it can prevent the illegal use and distribution of content of streamingly transmitted files due to illegal storage of the content.
