높은 부호화 효율을 추구하는 것과는 별개로, 최근, 실 세계의 모습을 보다 충실히 재현하거나 또는 보다 풍부한 밝기 및 색채로 영상을 표시하는 것을 가능하게 하기 위한, 영상 신호 표현의 확장이 진행되고 있다. HDR(High Dynamic Range)는, 종래의 표준적인 다이나믹 레인지인 SDR(Standard Dynamic Range)보다 넓은 휘도 다이나믹 레인지로 화상 또는 영상을 표현하려고 하는 개념이다. 예를 들어, HLG(Hybrid Log-Gamma), ST2084 또는 S-Log3이라고 하는 전달 함수(톤 커브라고도 한다)로 광을 화상 신호로 변환(및, 화상 신호를 광으로 변환)함으로써, 100nit보다 높은 휘도를 가지는 실 세계의 광을 디스플레이 상에서 재현하는 것이 가능하게 됨이 알려져 있다(HLG에 대해서는 비특허문헌 3 참조). 다른 예로서, ITU-R에 의해 표준화된 BT.2020은, 지금까지 많은 어플리케이션에서 사용되어 온 BT.709의 색역과 비교하여, 보다 선명한 색채를 표현하는 것을 가능하게 하는 색역을 정의하고 있다.
