Abstract: front page image
(EN)A method of modifying the volume level of an audio signal output from a media device is disclosed. The media device includes a memory, the memory includes a master volume memory location storing a master volume level, and one or more differential volume memory locations each of the one or more differential volume memory locations storing a differential volume level. The method includes: determining a modified volume level for the audio signal by summing the master volume level and one differential volume level; and outputting the audio signal at the modified volume level. Related apparatus and methods are also disclosed.
(FR)L'invention porte sur un procédé de modification du niveau de volume d'un signal audio délivré par un dispositif multimédia. Le dispositif multimédia comprend une mémoire, la mémoire comprend un emplacement de mémoire de volume maître stockant un niveau de volume maître, et un ou plusieurs emplacements de mémoire de volume différentiel, chacun des emplacements de mémoire de volume différentiel stockant un niveau de volume différentiel. Le procédé comprend : la détermination d'un niveau de volume modifié pour le signal audio par addition du niveau de volume maître et d'un niveau de volume différentiel; et l'émission du signal audio au niveau de volume modifié. Un appareil et des procédés apparentés sont également décrits.
