As a partner in the Centre for Digital Video Processing, the Visual Media Processing Group at Dublin City University conducts research and development in the area of digital video management. The current stage of development is demonstrated on our Web-based digital video system called Físchlár [1,2], which provides for efficient recording,
analyzing, browsing and viewing of digitally captured television programmes. In order to make the browsing of
programme material more efficient, users have requested the option of automatically deleting advertisement breaks.
Our initial work on this task focused on locating ad-breaks by detecting patterns of silent black frames which separate
