摘要

A device for synchronizing video data to be played back, has a client-side electronic data processing device (10) and a content representation unit (30). A content identification unit (60) has a device for extracting and forming identification data and as a reaction to a control signal, a control unit activates the content of the identification unit. On the server-side, associated content-related additional data is prepared for the identification data and/or the signature data. The additional data in the content representation unit (30) is then outputted.
