Coding & Visual Communications Group

• Advanced error-correcting coding is useful for both core and access networks. Applications in radio and satellite communication have been the most important for many years. All present wireless systems apply error-correction and they would not be possible without. In optical communication, it is becoming a strategic discipline for high capacity long distance transmission 
• The image and video coding activities are directed towards multimedia applications where a variety of image and video data needs to be coded efficiently for optimal use of the available communication bandwidth or storage capacity. An example is MPEG for video. Examples of research activities within the group are: Improving video quality for flat panel displays, Video for satellite and space communication, the newest MPEG-4 (H.264) and applications for that. A new area is distributed video coding enabling small, but still efficient video encoders, e.g. for wireless communication.
