Abstract:
With the increased diffusion of MP3 Players, Podcasting, 3G and 3.5G Mobiles with inbuild audio and video players (DVB-H) and Triple-Play (featuring IPTV or Video-over-IP) a number of new ways of audio delivery to the consumer have become A reality. New devices enter into the living room, like WLAN-based Audio Servers, which—unlike classical HiFi equipment—are based on PC technology. This trend toward IP-based transmission of encoded voice, audio, and video, either stand-alone, or audio accompanying video presentations, challenges established "best practice" methods for audio quality measurement. Equipment manufacturers, content providers as well as audio professionals must face a variety of new hardware designs, new transmission artIfacts, and finally new ways of presentation. For example, flat panel displays (LCD, Plasma) apply significant video processing and, as such, introduce a source of delay for A/V presentation. IP-based transmission may even cause varying delay, which will amplify lip-sync problems when compared to conventional TV. How do we tackle these new challenges by appropriate audio quality measurements? This workshop will try to present state-of-the-art conventional and advanced testing methods and pinpoint attempts to monitor and improve perceived audio quality.
