Abstract

Verfahren zur Übertragung von Szene-Daten in einem unidirektionalen Datenübertragungssystem Die Erfindung betrifft ein Verfahren zur Übertragung einer Mehrzahl mindestens eine Szene beschreibenden Szene-Datenfiles (SF1-SF4) mittels eines Datenkarussells von einem Sender (2) zu wenigstens einem Empfänger (3) eines unidirektionalen Daten- übertragungssystems (1), bei welchem durch das Datenkarussell ein Indexfile (IF) an den Empfänger (3) übertragen wird, in welchem eine zeitliche Anordnung der Szene-Datenfiles (SF1-SF4) für eine graphische Darstellung und/oder Dekodierung der Szene datentechnisch kodiert ist.
