A server (1) transmitting content of an MPEG-DASH standard to a client (2), includes a throughput measurement section (23) that measures a throughput of the server (1), an event information addition section (24) that generates obtainment destination switching instruction information instructing to switch an obtainment destination of the content to another content transmission device when the throughput is a predetermined value or more, and a content transmission section (22) that transmits segment data together with the obtainment destination switching instruction information. Hereby, the most suitable adaptive streaming is executed in real time.
