UTILIZATION OF INTELLECTUAL PROPERTY MANAGEMENT AND PROTECTION DATA FOR INTELLECTUAL PROPERTY MANAGEMENT AND PROTECTION FOR MPEG-N

摘要

PROBLEM TO BE SOLVED: To provide an MPEG-n IPMP System with extensive interoperability.;SOLUTION: It is defined also about some IPMP datagrams currently extended from this base class, as well as defining about IPMP_Data_Base Class. The IPMP data, which is a data describing IPMP information, comprises IPMP_Opaque Data, IPMP_Selective Decryption Message, IPMP_Audio Watermarking In it, IPMP_Video Watermarking In it, and IPMP_Key Data. From the above-mentioned contents, IPMP tool from vendor A can understand IPMP data configured by a content creation person B. Therefore, interoperability is realized, that is, a content protected becomes available on a MPEG-nIPMP terminal of a different vendor.;COPYRIGHT: (C)2004,JPO
