Abstract
A method of embedding copyright management information in AV (audio visual) content that is distributed in a downloadable file format. In a MP4 file format, which is a format for distributing downloadable files, content data is separated by code into a general stream and an IPMP (intellectual property management and protection) controlled media stream. A box for embedding data required for IPMP initialization and a box for embedding data required to interpret IPMP and related parameters are rendered in a first box that is rendered in a control data box.
