Zusammenfassung:	Disclosed is a video transmission method based on multi-HTTP threads for reducing viewpoint change delay in a multi-view video service. The method provides rapid video conversion to a user by reducing the viewpoint change delay compared to an existing multi-view video service by using a video transmission method based on the multi-HTTP thread to solve an increase of the viewpoint change delay due to an idle time generated every RTT in a single HTTP thread transmission method. The present invention comprises: a multi-view video streaming server which transmits a segment requested from a client; and a multi-view video streaming client which controls the number of HTTP threads based on a buffer occupying ratio of a client by a module for determining the number of HTTP threads. 다시점 비디오 서비스의 시점변경 지연을 줄이기 위한 다중 HTTP 스레드 기반의 비디오 전송 방법이 개시된다. 상기 방법은 단일 HTTP 스레드 전송 방식에서 매 RTT 마다 발생하는 유휴 시간으로 인해 시점변경 지연이 증가하는 문제를 해결하기 위해 다중 HTTP 스레드를 이용하여 비디오를 전송하는 방식을 사용하여 기존 다시점 비디오 서비스보다 시점변경 지연을 감소시킴으로써 사용자에게 빠른 영상 전환을 제공한다.
