This invention provides a method for interleaving bits of a digital signal representative of data and/or audio in a digital audio broadcasting system, the method comprising the step of: writing a plurality of bits of the digital signal to a matrix (Fig.22); and reading the bits from the matrix, wherein at least one of the writing and reading steps follows a non-sequential addressing scheme. Apparatus for transmitting the interleaved bits, and apparatus for receiving and deinterleaving the bits are also provided.

La présente invention a trait à un procédé permettant l'entrelacement de bits d'un signal digital représentatif de données et/ou de sons dans un système de diffusion audio numérique, le procédé comprenant les étapes suivantes : l'écriture d'une pluralité de bits du signal numérique dans une matrice (Fig.22), la lecture des bits à partir de la matrice, dans lequel au moins une des étapes d'écriture et de lecture suit un schéma d'adressage non séquentiel. L'invention a également trait à un appareil pour la transmission des bits entrelacés, et un appareil pour la réception et le désentrelacement des bits.
