Device and process for the read-synchronization of video and ancillary data

摘要

The present invention relates to a device (1) and a process for the read-synchronization of video data and of ancillary data, these data being recorded in a storage space (15) in multiplexed and chronological form. <??>The synchronization device comprises modules for inputting (2) and demultiplexing (3) the recorded data, the video and ancillary data being respectively transmitted to video reading (20) and ancillary (30) assemblies, which read and communicate these data. It also comprises an apprising module (4) capable of obtaining information from the video reading assembly (20) as regards instants of communication of video data, and an adaptation module (5) designed to adjust instants of communication by the ancillary reading assembly (30) of the ancillary data, as a function of the information obtained by the apprising module (4). <??>Applications to subtitling and to interactivity. <IMAGE>
