The invention concerns the adaptation of a transmission chain to transmission conditions. A device designed to optimise a transmitter comprises at least an element for evaluating, on the basis of received quality indicator(s), the optimisation to be brought to at least one parameter of said transmitter, in particular of at least an element of its transmission chain. In addition, the broadcasting system comprises at least: a transmitter receiving the optimised parameters adjusting the parameters of at least an element of its transmission chain and transmitting a signal comprising at least an audio programme and the parametering of its transmission chain, a reference receiver receiving the signal transmitted by said transmitter delivering a signal containing at least a quality indicator, and an optimising device receiving said signal with quality indicator and delivering adjusting parameters to said transmitter.

L'invention concerne l'adaptation d'une chaîne d'émission aux conditions de transmission. Un dispositif destiné à optimiser un émetteur comporte au moins un élément permettant d'évaluer, en fonction du ou des indicateurs de qualité reçus, l'optimisation à apporter à au moins un paramètre dudit émetteur, en particulier d'au moins un élément de sa chaîne d'émission. En outre, le système de diffusion comporte au moins: un émetteur recevant des paramètres optimisés venant régler les paramètres d'un moins un élément de sa chaîne d'émission et émettant un signal comportant au moins un programme audio et le paramétrage de sa chaîne d'émission, un récepteur de référence recevant le signal émis par ledit émetteur et délivrant un signal contenant au moins un indicateur de qualité, et un dispositif d'optimisation recevant ledit signal avec indicateur de qualité et délivrant les paramètres de réglage audit émetteur.
