Distributed audio visual system and content directory management system and method thereof
First Claim
1. 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.

Abstract
A distributed audio visual (AV) system including a plurality of media servers, a media renderer, and a control point which are connected to each other via a peer-to-peer network is provided. Each of the media servers includes a content directory management unit (CDMU) and a query content information (QCI) module, wherein the CDMU includes a synchronizer module and a content information maintainer (CIM) module. The synchronizer module synchronizes content information of AV contents stored in all the media servers. The CIM module records the content information and establishes an integrated content directory list according to the content information. The QCI module queries the content information. The control point obtains the integrated content directory list from one of the media servers and queries the content information related to all the AV contents, so as to control the media renderer to play the AV contents.
