Abstract

Existing MPEG-4 players have limitation of screen blinks and drops of object rendering speed when user insert, delete, and replace objects on scenes. In this paper, an Object Priority Order Composition operated through the MPEG-4 player is proposed. This composition is the method for presentation user can insert, delete, and replace scene objects more efficiently. Therefore, this composition can show the MPEG-4 multimedia scenes without blinks and delays on MPR-4 player may seem random and natural.

기존에 개발된 MPEG-4 플레이어들을 살펴보면, 객체의 삽입, 삭제, 갱신과 같은 사용자 상호작용에 의한 시청각 장면 프리젠테이션시 전체 미디어 객체를 다시 프리젠테이션해야 하므로 화면이 껌뻑이거나 프리젠테이션 속도가 느렸다. 본 논문에서는 이를 개선하기 위해 객체 우선 순위 컴포지션 방법을 제안한다. 이는 복합 미디어 객체로 구성된 시청각 장면을 사용자 상호자용에 의해 실시간으로 객체가 삽입, 삭제, 갱신되는 장면 변화를 보다 효율적으로 프리젠테이션하는 방법이다. 제안된 방법으로 구현한 결과는 MPEG-4 스트림의 즉각적이고 자연스러운 프리젠테이션이 가능함을 보여준다
