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.

Abstract translation: 一种用于包括单独数字样本序列的数字信号数据流的前向错误隐藏编码的方法包括根据从多个预定编码模式中选择的编码模式来编码一个或多个单独的数字样本， 相应的数字样本，其中编码包括根据所选择的编码模式将编码的数字样本确定为相应数字样本的比特的组合和布置到编码数字样本的预定比特位置的预定数量的前向错误隐藏比特。 提供了一种包括编码的单独数字样本序列的数字信号数据流的前向错误隐藏解码的方法，包括根据从多个编码样本中选择的解码模式将一个或多个单独编码样本解码为各个解码的数字样本 预定解码。
