N2 - High definition video over IP based networks (IPTV) has become a mainstay in today's consumer environment. In most applications, encoders conforming to the H.264/AVC standard are used. But even within one standard, often a wide range of coding tools are available that can deliver a vastly different visual quality. Therefore we evaluate in this contribution different coding technologies, using different encoder settings of H.264/AVC, but also a completely different encoder like Dirac. We cover a wide range of different bitrates from ADSL to VDSL and different content, with low and high demand on the encoders. As PSNR is not well suited to describe the perceived visual quality, we conducted extensive subject tests to determine the visual quality. Our results show that for currently common bitrates, the visual quality can be more than doubled, if the same coding technology, but different coding tools are used.
