Patent ID: 8452802

Claim:
A content directory management system, comprising: a first media server, storing first audio visual (AV) contents, wherein the first media server includes a first content directory management unit (CDMU) and a first query content information (QCI) and the first CDMU includes a first synchronizer module and a first content information maintainer (CIM) module; and a second media server, storing second AV contents, wherein the second media server includes a second CDMU and a second QCI and the second CDMU includes a second synchronizer module and a second CIM module, wherein the first CIM module records first content information related to the first AV contents and the first synchronizer module transmits the first content information to the second synchronizer module, wherein the second CIM module records second content information related to the second AV contents and the second synchronizer module transmits the second content information to the first synchronizer module, wherein the first CIM module records a first synchronized content information in the first media server according to the first content information and the second content information and updates a first integrated content directory list in the first media server based on the first synchronized content information, wherein the second CIM module records a second synchronized content information in the second media server according to the first content information and the second content information and updates a second integrated content directory list in the second media server based on the second synchronized content information, wherein the first synchronized content information in the first media server is the same as the second synchronized content information in the second media server, wherein the first QCI queries the first integrated content directory list and the second QCI queries the second integrated content directory list, wherein the first media server and the second server are connected via a peer-to-peer network, wherein the first CDMU further comprises a first categorizer module for categorizing the first synchronized content information according to the file types of the first AV contents and the second AV contents, wherein the second CDMU further comprises a second categorizer module for categorizing the second synchronized content information according to the file types of the first AV contents and the second AV contents.
