Abstract
There is provided a method for processing an input signal (700). The input signal (700) is processed at least by converting the input signal (700) from a first colour space to a second colour space, to produce a first processed signal. The processed signal is encoded by a first encoding module (703) to generate a first encoded signal (710). A decoded signal is generated by decoding the first encoded signal (710). The decoded signal is processed at least by converting the decoded signal from the second colour space to the first colour space to produce a second processed signal. The second processed signal and the input signal (700) are processed by a second encoding module (707) to generate a second encoded signal (720).
