Abstract

In this paper, we propose a media processor to provide interactive services in mobile multimedia broadcasting environments. The proposed system Is designed to support various functionalities, such as generation of MPEG-4 IOD (Initial Object Descriptor)/OD(Object Descriptor)/BIFS (Binary Format for Scene) data, encapsulation of MPEG-4 AVC (Advanced Video Coding)/BSAC (Bit Sliced Arithmetic Coding) stream and generated IOD/OD/BIFS data into SL (Sync Layer) packet, packetization of SL packet into TS (Transport Stream) packet and multiplexing. The proposed media processor can provide MPEG-4 based interactive services for users.

본 논문에서는 이동 멀티미디어 방송 환경에서 대화형 서비스를 제공하기 위한 이동 멀티미디어 방송 미디어 처리기를 제안한다. 제안한 미디어 처리기는 오디오/비디오 부호화기로 MPEG-4 AVC(Advanced Video Coding) 및 MPEG-4 BSAC(Bit Sliced Arithmetic Coding) 부호화기를 사용하여, MPEG-4 IOD(Initial Object Descriptor)/OD(Object Descriptor)/BIFS(Binary Format for Scene) 데이터를 생성하는 기능, MPEG-4 AVC/BSAC 및 생성된 MPEG-4 OD/BIFS 데이터를 SL(Sync Layer) 패킷으로 캡슐화하는 기능, SL 패킷을 MPEG-2 TS(Transport Stream)로 패킷화하는 기능 및 다중화하는 기능을 지원할 수 있도록 설계하였다. 본 논문에서 제안한 이동 멀티미디어 방송 미디어 처리기는 사용자에게 MPEG-4 시스템 규격을 기반으로 대화형 서비스를 지원할 수 있다.
