Abstract
Pre-encoding a picture to be encoded by a coding process includes transformation and/or quantization, the picture including a plurality of samples of a predetermined bit-depth. After having split each of the samples of the picture into at least two sub-samples, each of the at least two sub-samples being of a predetermined bit-depth, the bit-depth of the samples being higher than the bit-depth of each of the at least two sub-samples, the at least two sub-samples of each of the samples are stored into at least two different components of at least one picture.
