ABSTRACT OF THE DISCLOSURE A system is disclosed for inserting and extracting a supplementary digital information signal into and from a Main digital information signal. Elements of the main signal corresponding to its extreme levels of quantization are indentified, and successive elements of the supplementary signal are inserted by selectively augmenting the elements so identified. Extraction of the supplementary signal in- volves identifying the same elements of the main signal and determining the selective augmentation applied thereto. The supplementary signal is arranged into a frame structure, and means are included to synchronize to this frame structure a receiver which extracts the supplementary signal.
