Abstract
A method and system for sample mapping in image and video coding using Low Dynamic Range (LDR) samples are provided. For example, mapping functions are implemented for conversion of samples from an original bit depth to an LDR bit depth during an encoding and decoding process of videos or images. Such mapping functions are signaled or indicated in a bitstream of the videos or images.
