Since years the ORF is famous for its live broadcasts of classical concerts, operas and operettas from various worldwide known open-air stages (Salzburg, Bregenz, Mörbisch) or concert halls (Salzburg, Vienna). Due to the popularity of these events througout Europe, the demand for DVDs and in the future also for high definition Blu-Rays and HD DVDs is obvious. Because of the cooperation of the ORF with DVD production companies an intensive post-production work has to be carried out before the DVD is released. This was one of the reasons why the ORF has decided to build a High Definition linear edit suite in its facilities in Vienna.
