Abstract (en)
[origin: WO9908449A1] A method of signal coding comprising the step of decomposing the signal into transform coefficients, further comprising the step of generating mask data indicating for which, of said transform coefficients, transform data will not be sent. The mask data may indicate the depth (in bit-planes) at which data will start to be sent for each coefficient.
