Abstract

A method is disclosed of recording an input signal 21 on an information carrier 12, comprising the steps of: - encoding the input signal so as to obtain a digital signal 10, with a level of resolution at an initial value, - storing the digital signal in a buffer 11, - recording the digital signal stored in the buffer on the information carrier, - temporarily suspending the recording, and - while the recording is temporarily suspended, having the level of resolution decreased to a lower value in encoding the input signal, wherein in decreasing the level of resolution to the lower value, said level of resolution is decreased gradually. In this way it is obtained that the decrease in the level of resolution is less perceptible during reproduction of the input signal.
