Abstract

This paper proposes the mechanism which improves the qualify of video on a limited network bandwidth by applying the ROI technique to an H.264 Scalable Extension technique. The network environment assumed in this parer is the next generation network convergence environment in which the mobile device has one or more network interfaces. Therefore, we allocate the priority to video packets as the hierarchy structure of H.264 SVC-encoded video stream and ROI information, and transmit those packets over appropriate network channel for using those multiple network interfaces. This paper shows two experiments first one is extracting and allocating the video stream on an appropriate network channel, second one is unequal packet transmission by allocated priorities (e.g. ROI). Performance evaluations show that this approach delivers an improved decoded video quality when compared with conventional transmission schemes, especially on device which has multiple network interfaces.

본 논문은 사용자의 주관적/객관적 화질 개선을 위해 ROI(Region Of Interest) 기법과 다중 채널 기법을 H.264 Scalable Extension에 적용하여 제한된 네트워크 대역폭에서 최적의 화질을 얻는 기법을 제안한다. 논문에서 가정하는 네트워크 환경은 모바일 디바이스가 하나 이상의 네트워크 인터페이스를 가지는 차세대 네트워크 컨버전스 환경이다. 따라서, H.264 SVC의 기초 계층 정보와 ROI 정보에 대해 우선 순위를 두어 다중 채널로 전송한다. 실험은 비디오 추출 및 채널 할당에 대한 실험과 ROI 영역에 대한 차별적 전송 실험으로 구성되었으며, 제안하는 기법이 기존 방식에 비해 PSNR 화질 비교에 있어서 더 나은 성능을 보임으로써 제안하는 기법의 우수성을 입증하고 있다.
