<p><P>PROBLEM TO BE SOLVED: To accurately manage an intellectual property of media data by surely synchronizing, at regeneration, a coded media data with a coded intellectual property management data for managing the intellectual property of the media data. <P>SOLUTION: A first coding part (701) encodes the media data. A second coding part (703) encodes an intellectual property management of media data. A transmission part (710) packets (707) a coded media data, a first timing information for controlling decoding timing to the media data, a coded intellectual property management data, a second timing information for controlling decoding timing of the coded intellectual property management data, and a synchronizing information for synchronizing with the media data, for transmission. <P>COPYRIGHT: (C)2004,JPO</p> |
