CA 2100476
The effects of perturbations in a decoder responsive to a signal encoded in a predictive coding schema are reduced by shortening the time needed to converge the decoder's prediction signal to that of the encoder. This is accomplished by temporarily altering the leak factor when it is known that a perturbation is about to manifest itself and by, in some situations, altering the incoming encoded signalitself.
On atténue les effets des perturbations dans un décodeur qui réagit à la réception d'un signal à codage prédictif en réduisant le temps nécessaire pour faire converger le signal de prédiction du décodeur et le signal du codeur. Ceci se fait en modifiant temporairement le facteur de perte à l'approche d'une perturbation et, dans certaines situations, en modifiant le signal codé incident lui-même.
