멀티미디어 컨텐츠의 수요와 공급이 증가함에 따라 전 세계의 인터넷 트래픽이 증가하는 가운데 이를 완화하기 위해 여러 표준화 그룹에서는 더 효율적인 압축 표준을 제정하는데 노력을 기울이고 있다. 이러한 노력 중 압축 표준에 딥러닝 기술을 도입하고자 하는 연구들이 활발히 진행되고 있다. 그러나 딥러닝 기반 압축 기술은 학습 데이터와 특성이 다른 영상을 압축할 때 압축 효율이 저하되는 문제를 갖는다. 이를 해결하기 위해 컨텐츠에 적응적으로 딥러닝 기술을 도입하는 시도들이 있었다. 본 논문에서는 이들을 크게 코덱 정보 사용, 모델 선택, 추가 정보 전송의 세 가지로 나누어 살펴보고자 한다.
