The invention concerns a method (200) and system (100) for creating a subset of channels with programming from a plurality of channels and can include the steps of: receiving (210) a plurality of channels, wherein the plurality of channels comprises at least one channel with programming; encoding (212) at least a portion of predetermined number of channels from the plurality of channels to provide a corresponding encoded signal for each of the predetermined number of channels; processing (214) each of the corresponding emcoded signals to determine wich of the predetermined number of channels contain programming to provide the subset of channels with programming; and storing (216) the subset of channels into memory. the invention can also include the step of analyzing at least a portion of an audio signal in the predetermined channels to determine which of the predetermined channels to determine which of the predetermined channels contain programming.

L'invention concerne un procédé (200) et un système (100) de création d'une sous-série de canaux dotés d'une programmation à partir d'une pluralité de canaux, lesdits procédés et système comprenant les étapes de réception (210) d'une pluralité de canaux qui comporte au moins un canal avec programmation, de codage (21) d'au moins une partie du nombre prédéterminé de canaux parmi ladite pluralité pour produire un signal codé correspondant pour chaque canal de ce nombre prédéterminé de canaux, de traitement (214) de chacun des signaux codés correspondants afin de déterminer lequel des canaux dudit nombre prédéterminé contient une programmation de manière à fournir à la sous-série de canaux une programmation, et de stockage (216) de la sous-série de canaux dans la mémoire. Cette invention peut également comprendre l'étape d'analyse d'au moins une partie d'un signal audio dans les canaux prédéterminés, en vue de déterminer lequel des canaux prédéterminés contient la programmation.
