The present invention relates to a device (1) and a process for thenread-synchronization of video data and of ancillary data, these data beingnrecorded in a storage space (15) in multiplexed and chronological form. n The synchronization device comprises modules for inputting (2)nand demultiplexing (3) the recorded data, the video and ancillary data beingnrespectively transmitted to video reading (20) and ancillary (30) assemblies,nwhich read and communicate these data. It also comprises an apprisingnmodule (4) capable of obtaining information from the video reading assemblyn(20) as regards instants of communication of video data, and an adaptationnmodule (5) designed to adjust instants of communication by the ancillarynreading assembly (30) of the ancillary data, as a function of the informationnobtained by the apprising module (4). n Applications to subtitling and to interactivity. |
