    • A process for distributing digital audio sequences according to a nominal flux format including a succession of fields, each of which includes at least one digital block clusterizing a selected number of coefficients corresponding to single audio elements that are digitally coded inside the flux and utilized by audio decoders that are able to play it to be able to decode it correctly, including a preparatory step including modifying at least one of the coefficients, and a transmission step including a primary flux in compliance with a nominal format including blocks that were modified during the preparatory step and by a route separated from the primary flux by an additional piece of digital information which allows reconstruction of the original flux starting with a calculation, on recipient equipment, as a function of the primary flux and of the additional information.
    • 根据包括一系列字段的标称通量格式来分配数字音频序列的过程,每个字段包括至少一个数字块,所述至少一个数字块将对应于通量内的数字编码的单个音频元素的选定数量的系数聚类并被音频利用 能够播放它以能够正确解码的解码器,包括准备步骤,包括修改系数中的至少一个,以及传输步骤,包括符合包括在准备期间被修改的块的标称格式的主要通量 通过附加的数字信息片段与主要通量分离的路线,其允许从接收设备开始的计算开始重建原始通量,作为主要通量和附加信息的函数。
