Abstract

In this paper, a method for transmitting layered SVC streams in differentiated MBSFN channels is presented. Scalable coded video streams are transmitted in modulation channels of different efficiency that it achieves reduced resource consumption compared to non-scalable AVC stream. When utilizing with Raptor FEC, the combined effect is enhanced service coverage with providing minimum video quality at the edge of the service area, than the case of AVC.

본 논문에서는 MBSFN (Multicast Broadcast Single Frequency Networks)영역에서 비디오 서비스 영역(coverage)을 SVC (Scalable Video Coding)와 계층 차별적 변조 방법을 이용하여 개선시킴을 보였다. 계층적으로 압축된 SVC 비디오 데이터의 각 계층에 따라 변조 방법을 다르게 적용하고, 또한 Raptor FEC (Forward Error Correction)를 이용함으로 기존의 단일계층 AVC (Advanced Video Coding)비디오를 이용하는 것 보다 최소 품질의 서비스 영역을 제공 할 수 있다는 것을 증명 하였다.
