본 논문에서는 SVC 의 계층 부호화 구조를 고려하여 layered FEC와 ARQ를 오류강인 기법으로 선택하며 보다 효과적인 오류강인 성능을 확보하기 위하여 이들 기법을 복합적인 형태로 동작시킬 수 있는 복합형 (hybrid) 오류제어 방법에 대해 제안하고, 제안된 방법들의 성능을 비교 분석한다. 또한, 제안하는 오류 강인 기법이 실용적으로 구현될 수 있도록 SVC NAL 단위를 일정 단위의 오류 강인 패킷으로 만들어 주는 패킷화 방법을 제안한다. 제안된 오류 강인 기법의 성능을 검증하기 위하여 패킷 손실 네트워크 환경을 NIST-NET을 활용하여 구축하며, 실험 결과를 통해 복합적 오류제어 기법의 성능이 우수함을 보인다.
