패킷 손실 및 지연은 IP 네트워크를 통한 실시간 음성 전송의 주요 네트워크 장애입니다. 제안 시스템에서는 패킷 경로의 다양성을 활용하기 위해 음성에 대한 다중 설명이 사용됩니다. 다중 스트림 음성 전송의 인지된 품질을 예측하기 위한 새로운 객관적인 방법이 제시됩니다. 또한 적응형 매개변수 조정 방식과 함께 지연 손실 거래를 통해 인식된 음성 품질을 최대화하는 멀티 스트림 재생 버퍼 알고리즘도 제안됩니다. 실험 결과, 제안된 다중 스트림 전송 방식은 FEC로 보호되는 단일 경로 전송과 비교하여 지연 및 패킷 손실률이 크게 감소하고 음성 품질이 향상되는 것으로 나타났습니다.

Abstract: Packet loss and delay are the major network impairments for transporting real-time voice over IP networks. In the proposed system, multiple descriptions of the speech are used to take advantage of the packet path diversity. A new objective method is presented for predicting the perceived quality of multi-stream voice transmission. Also proposed is a multi-stream playout buffer algorithm, together with an adaptive parameter adjustment scheme, that maximizes the perceived speech quality via delay-loss trading. Experimental results showed that, compared to FEC-protected single-path transmission, the proposed multi-stream transmission scheme achieves significant reductions in delay and packet loss rates as well as improved speech quality.
