摘要： An apparatus and method allowing for high-quality data acquisition and playback processing based on content information transmitted from a server to a client are provided. Property information constituting meta-information corresponding to content-associated attribute information stores data-scheme information on original content held by the server, such as file format information, codec information representing an encoded-data scheme, and resolution information. In response to a content information acquisition request from the client, content information including the data-scheme information on the original content is generated and is transmitted to the client. This structure allows the client to output a content transmission request in which the optimum data scheme is determined based on the data scheme of the original content. Therefore, high-quality data acquisition and playback can be achieved.

摘要： Apparatus and a method are provided, which efficiently and properly execute information update processing and content reproduction processing based on transmission processing of content information from a server to a client. The server owning content attribute information extracts metadata based on an information acquisition request from the client, to generate the content information based on property information which is a component of the metadata, and for each property, sets data editing information allowed by each piece of the property information to transmit to the client. Furthermore, the server generates the content information including data mode information by which processing capability in a device on the client side can be judged, such as record quality level information and codec information, as the data mode information of the contents.
