摘要： At the time of transmitting content from a first apparatus holding the content through a specified transmission path to a second apparatus so that transmission of content can be controlled simply among a plurality of AV apparatus using a general purpose network, each content held by the first apparatus is added with the information of transfer protocol for outputting that content when the information of that content is disclosed to a controller existing on the transmission line. When transmission of content is started between the first and second apparatus, transmission is managed based on the information of transfer protocol added to that content.

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.
