Abstract

HTTP 스트리밍 전송 중에 표현 스위칭이 일어날 경우의 자연스러운 재생을 가능케 하는 처리 방법이 개시된다. 표현 스위칭이 일어나지 않는 경우의 세그먼트들에 대한 정보를 저장하고 있는 제 1 미디어 정보 파일과, 표현 스위칭이 일어나는 경우의 세그먼트들에 대한 정보를 저장하고 있는 제 2 미디어 정보 파일을 수신하고, 표현 스위칭이 일어나지 않는 경우는 상기 제 1 정보를 참조하여 상기 수신 대상 컨텐츠의 세그먼트들을 수신하여 재생하며, 표현 스위칭이 일어나는 경우는 상기 제 2 정보를 참조하여 상기 수신 대상 컨텐츠의 세그먼트들을 수신하여 재생한다. 따라서, 동적으로 변화하는 채널 환경에 따라 화면의 끊김 없이 멀티미디어 컨텐츠를 제공할 수 있다.
