Abstract
The invention concerns scaling color difference components prior to encoding in order to extend the dynamic range. In one embodiment the color difference components are encoded prior to quantization. In another embodiment the color difference components are encoded after quantization. A decoder is configured to process data representative of the gain factor for a decoding process.
