Abstract audio codec willing to communicate a position; audio decoder to receive a given position by at least a first value and a second value; method for an audio decoder communicate a position; method for an audio decoder to receive a posi Tion given by at least a first value and a second value; audio bit stream; and the product of program withThe present invention putador refers to a receiver (603) which receives a position given by a first value representing a first parameter of position and a second value which represents a second measure of position. A comparison circuit (605) determines if the second value is Equal to a nominal value.If it is, then, an output circuit (609) generates output data that includes data representing the first value in a field of data output, but not include data representing the second value in the output data. Otherwise, the output circuit (609) includes, in the field, data representing a position value invalid for the first parameter position.A receiver determines whether data of a data field representing a position value valid for the first parameter of position. If the response is positive, it determines a position with the first value and the position value and the second value being valid for a nominal value The second parameter position.Otherwise, it determines the second value from a second field of the input data.
