<p>In source coding use can be made of switching filter banks in order to adapt the filter bank to properties of the signal to be coded. If it is not allowed that the switching introduces transient phenomena in the reconstructed signal, so-called boundary filters have to be used. In the system according to the present invention, it is possible to dispose with the transition filters without introducing undesired transient phenomena. In order to obtain said property the new filter coefficients (after switching) have to be a linear combination of the original filter coefficients (before switching).</p> |
