APPARATUS AND METHOD OF FLEXIBLE AND COMMON IPMP SYSTEM FOR PROVIDING AND PROTECTING CONTENT
摘要
An apparatus of a flexible and common IPMP (intellectual property management and protection) system gives acquiring and mutual operability to the system by fetching a complete IPMP tool list held by a content stream or downloaded from the URL position. The apparatus provides an IPMP tool manager of a conforming IPMP terminal functioning as a pre−processing module, syntactically analyzes the IPMP tool list, and acquires an IPMP tool according to the IPMP tool ID, a position identifier related to it, and the IPMP tool format ID. By pre−compiling the IPMP tool into a binary format, the IPMP tool can be transferred or downloaded to the IPMP terminal, and a different binary format is prepared by a content provider for an object on a different platform of the IPMP terminal.
