Abstract
A method for forward error concealment encoding of a digital signal data stream including a sequence of individual digital samples, includes encoding one or more of the individual digital samples according to an encoding mode selected from a number of predetermined encoding modes in accordance with a value of the respective digital sample, wherein encoding includes determining an encoded digital sample as a combination of bits of the respective digital sample and a predetermined number of forward error concealment bits arranged into predetermined bit positions of the encoded digital sample in accordance with the selected encoding mode. A method for forward error concealment decoding of a digital signal data stream including a sequence of encoded individual digital samples is provided, and includes decoding one or more of the individual encoded samples into respective decoded digital samples according to a decoding mode selected from a number of predetermined decoding.
