Abstract: The availability of different HDTV image formats such as 720p/50 or 1080i/25 and 1080p/50 as a potential future format poses the question for many users on what HDTV format to use with which compression algorithm and at what bit rate. Subjective testing according to the well-know standards of the ITU-R BT.500–11 only provides the failure characteristic of each individual HDTV format. The European Broadcast Union (EBU) has developed a new subjective testing method called the triple stimulus continuous evaluation scale (TSCES) for HDTV formats and has used this method with over 300 assessors to investigate the various HDTV formats on different flat panel displays. H.264/AVC was used as a compression system at broadcast bit rates. Thus, comparative graphs between the different HDTV formats were possible and have shown that progressive scanning formats outperform HDTV with 1080i/25. Although the results have also proven that 720p/50 is currently the favorable emission format, there are also indicators for the potential of 1080p/50.

bio
Hans Hoffmann was born in Munich, Germany. He holds a diploma in telecommunication engineering from the University of Applied Sciences in Munich. In 2007, he completed his Ph.D. studies at Brunel University West London, at the School of Engineering and Design. From 1993 to 2000, Hoffmann worked at the Insitut fuer Rundfunktechnik in research and development for new television production technologies. In 2000, he joined EBU as a senior engineer in the technical department. Hoffmann has chaired the EBU project groups P/BRRTV and P/PITV, which were both involved in standardization activities such SDTI and file formats. Hoffmann actively participates in SMPTE engineering meetings; he chaired the SMPTE technology committee on Networks and File Management and was appointed as Engineering Director, Television. For the past four years, he has been involved in EBU activities on high-definition television production and emission and set up the HDTV testing laboratory at the EBU. Hoffmann is a fellow of SMPTE and a member of the Institute of Electrical and Electronics Engineers (IEEE), FKT (Germany), and the Society for Information Display (SID).

bio
Takebumi Itagaki received a B.E. in applied physics from Waseda University (Japan) in 1990, a postgraduate diploma in music information technology from City University (U.K.) in 1992, and a Ph.D. in engineering from the University of Durham (U.K.) in 1998. Since 2000, he has been a lecturer at the School of Engineering & Design, Brunel University (U.K.). At Brunel, Itagaki served as a coordinator and a manager of EU-IST projects; Savant ( www.savant.tv/ ) and Instinct ( www.ist-instinct.org/ ), and contributed to several EU-IST projects. His research interests include digital signal processing, realtime systems, parallel and distributed systems, interactive digital TV systems, and HDTV. Itagaki is a member of IEEE, the Audio Engineering Society (AES) and the Institution of Engineering and Technology (IET).
D. Wood
bio
David Wood is head of new media at the EBU. He has chaired new media coordination activities for the EU-IST program for many years, and chaired several Working Groups in the International Telecommunications Union (ITU). He is particularly interested in the future success of radio as a media form in the new media environment, and in the evolution of audio components of television. Wood was educated at Southampton University in the U.K., the UNIIRT in Odessa, and the Harvard Business School in the U.S. He worked at the British Broadcasting Corp. (BBC) and the IBA in the U.K. before joining the EBU.
