1. A signal processing system, comprising:
one or more processors configured to
apply a first optical-optical transfer function (OOTF) conversion corresponding to a first signal interface to an input linear video signal, wherein the input linear video signal is a high dynamic range (HDR) signal, and the first signal interface is one of Hybrid Log-Gamma (HLG), Perceptual Quantizer (PQ), and S-Log 3, and
apply a grayscale compression process corresponding to a second signal interface, the second signal interface being one of HLG, PQ, and S-Log 3 but different from the first signal interface.
