Abrégé
(EN)
The invention relates to a method of receiving digital television services, which comprises a step (61) of receiving at least one information representative of the lag in the display of a new service, the information being inserted into control data which comprise at least one list of services. Thus, the invention allows the receiver to perform an action during the loading of a service as a function of this time. The invention also relates to the corresponding sending method.
(FR)
La présente invention concerne un procédé de réception de services de télévision numérique, qui comprend une étape (61) de réception d'au moins une information représentant le décalage dans l'affichage d'un nouveau service, l'information étant insérée dans des données de commande comprenant au moins une liste de services. L'invention permet donc au récepteur d'effectuer une action pendant le chargement d'un service en fonction de ce temps. L'invention concerne également un procédé d'émission correspondant.
