METHODS OF USE OF IPMP DATA FOR MPEG-N IPMP (INTELLECTUAL PROPERTY MANAGEMENT AND PROTECTION)

摘要

MPEG-n IPMP systems have the offer of extensive interoperability. For this purpose, IPMP_Data_BaseClass, defines several IPMP data and is also defined from the base class. IPMP data describe the data of IPMP message events, it includes: IPMP_OpaqueData; IPMP_SelectiveDecryptionMessage; IPMP_AudioWatermarkingInit; IPMP_VideoWatermarkingInit; And IPMP_KeyData. The place of the mode of IPMP data is also designated from IPMP_Data_BaseClass. Using above-mentioned work, the IPMP tools from supplier will be appreciated from the IPMP data of construction by content author B, therefore the ability that will realize collaboration aspect, same protected content will consume the MPEG-n IPMP terminals in different vendor.
