摘要

In a case where a request from a client (2) requests transmission of a segment, a content transmission portion (22) of a server (1) waits until the segment is in a deliverable state and transmits a response that contains the segment to the client (2) after the segment is in the deliverable state. This enables reduction in delay and execution of high quality and low-latency live streaming.
