Abstract
Videoanwendungen, die auf einzelne Segmente eines kodierten Mediums zugreifen, benötigen Informationen über die Struktur der Daten. Um diese Strukturinformation zu erhalten, müssen kodierte Videodaten geparst werden. Diese Informationen werden üblicherweise nicht persistent gehalten, was bei einem wiederholten Zugriff ineffizient ist. Dieser Artikel beschreibt die Integration eines MPEG-Parsers in ein erweiterbares Datenbankmanagementsystem. Dadurch werden Funktionen für den Zugriff auf inhaltsbezogene Daten wie auch grundlegende Funktionen zum Extrahieren von Datenströmen oder Dekodieren einzelner Bilder als Datenbankfuntionalität zur Verfügung gestellt. Dieses sogenannte MPEG-DataBlade bildet die Grundlage für zukünftige Erweiterungen eines MM-DBMS
