Raquel Navarro-Prieto Fundació Barcelona Media Universitat Pompeu Fabra Ocata 1, 08003 Barcelona, Spain [email protected] rg Converged technologies are seen as the new leap forward in integrating the latest advances on various digital mobile radio networks. Nevertheless, the new levels of flexibility that these new technologies could introduce increases further the complexity confronted by users, and potentially lowers the usability and ease of use of, especially for services like mobile TV. Our research goal was to understand which an acceptable quality is for mobile TV. We concluded that the methods proposed by the existing standards did not match our goals because of the conditions in which our content would be shown and the qualities to be implanted are very far from the existing standards. Next, we described an innovative methodology introduced last year based on psychophysics, for sport sequences. We have adapted that methodology and carried out a study were we tested two situations, mobile TV sequences on a mobile phone screen (MPEG 4 compression) and PDA screen (MPEG 2 compression). We tested three types of content: news, sport and music video clip. In the final paper we would include a brief summary of the results.
