• Management of IPR, conditional access, permissions, transactions, user authentication and addressibility;
• Audit trails and modification history;
• Integrity and authenticity of IPI Information, IPR Information, modification history information and payload;
• Real time issues and synchronization;
• Interfaces between MPEG-4 and external systems (e.g. CORBA, DCOM, COM, etc.);
• External security systems, watermarking and cryptography.
