Title
(EN) SYSTEM AND METHOD FOR SYNCHRONIZING AN APPLICATION WITH AUDIO CONTENT
(FR) SYSTÈME ET PROCÉDÉ DE SYNCHRONISATION D'UNE APPLICATION AVEC UN CONTENU AUDIO
Abstract
(EN)
According to the invention, an application is to be synchronized with audio content designed to be consumed via a consumer terminal. The content is provided in the form of a stream of audio data time-stamped according to a first timing reference. The application is executed according to a second timing reference. Synchronizing the application with the audio content comprises the steps of: obtaining (6.4) audio data of said time-stamped content, on the basis of the second timing reference, in order to indicate respective instants at which said audio data is consumed via said consumer terminal; determining (6.6) information on the correlation between the audio data; determining (6.7) information on the time offset between the first and second timing references on the basis of the determined correlation information and of the data time-stamping information; and synchronizing the application with said content on the basis of said time-offset information.
