METADATA SHARING SYSTEM, SERVER DEVICE, CLIENT DEVICE, AND METADATA SHARING METHOD

摘要

PPROBLEM TO BE SOLVED: To correctly specify a target content when requesting metadata, in a metadata sharing system in which a metadata is shared by a plurality of users. PSOLUTION: A client 1 includes a metadata generating part 113 for generating metadata, and a metadata requesting part 118 which requests a wanted metadata from a server 2. The server 2 includes a metadata managing part 212 which manages the metadata received from the client 1, and a metadata distribution part 217 which distributes the metadata requested from the client 1. The metadata generating part 113 describes EPG information as the information of the content which the metadata belongs to. The metadata managing part 212 discriminates content based on the EPG information to manage the metadata for each content. PCOPYRIGHT: (C)2009,JPO&INPIT
