Broadcasters need a simple but highly effective quality control for media files,both for their archives and for their production. Quality control concerns the conformity to certain standards (such as file compression formats) and the evaluation of audiovisual quality. The specialized products that already exist, provide a report that is very difficult to interprete by a non-expert.
This project intends to address this problem by developing an algorithm that analyzes these reports and automatically interpretes them thus giving the operator a simple decision in the form of a red, green or orange light. It is particularly important that erroneous files do not result in a green light. Normally there are much more good than bad files. Restricting the visual check to only the files that have resulted in a red or orange light could mean a significant time saving.
The project consists of three phases. Firstly media files that contain both good and bad files undergo testing by a number of quality tools. As many as possible reports should be generated this way. Secondly research is needed on how the automatically generated test reports can be interpreted so that an operator immediately knows if something is seriously wrong with a particular file. This will require investigation of machine learning techniques. Finally, the developed algorithms are evaluated in an existing workflow (cf. the project Vlaanderen in Beeld)).
