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.
