摘要

A content receiving client device has a metadata obtaining unit, a message generating unit, and a message sending unit. The metadata obtaining unit obtains metadata including information used to generate an invite message for prompting establishment of a session for receiving content from a content distribution server. The message generating unit generates, based on the metadata, the invite message. The invite message includes a destination address field storing location information specifying a location of the content. The invite message further includes a body field storing information used to establish the session. The message sending unit sends the invite message to a session control server that controls the session.
