Abstract

Within the scope of the EU-funded project porTiVity (portable interactivity), an application has been developed, that automatically modifies SDTV (Standard Definition Television) sports productions for viewing on mobile TV displays by means of intelligent cropping and scaling. It crops regions of interest of sports productions based on a smart combination of production metadata and systematic video analysis methods. This approach allows a context-based composition for cropped images. It provides a differentiation between the original SD-version of the production and the processed one adapted to the requirements for mobile TV. Envisaged is the integration of the tool in post-production and live workflows.
