Abstract

Die Erfindung betrifft ein Verfahren zur zeitlichen Synchronisierung von Datenpaketen wenigstens eines Mediendatenstroms (AS, VS) mit wenigstens eine Szene beschreibenden Szene- Datenfiles (A-E) und/oder deren Datenpaketen eines unidirektionalen Datenübertragungssystems (1), wobei die Datenpakete des Mediendatenstroms (AS, VS) jeweils mit einer auf eine erste Referenzzeit (ZSl, ZS2) bezogenen ersten Zeitmarke versehen sind und die Sezene-Datenf iles (A-E) und/oder deren Da- tenpakete jeweils mit einer auf eine zweite Referenzzeit (ZS3) bezogenen zweiten Zeitmarke versehen sind, wobei wenigstens ein Zeitmarkenzuordnungsdatenstrom (SRA, SRV, SRS) vom Sender (2) zum Empfänger (3) übertragen wird, in dem die ersten Zeitmarken des Mediendatenstroms (AS, VS) und die zweiten Zeitmarken der Szene-Datenfiles (A-E) und/oder deren Datenpakete jeweils einer auf eine dritte Referenzzeit (ZS*) bezogenen dritten Zeitmarke zugeordnet sind.
