Abstract
Virtual collaboration concept allows remotely located partners to meet in a virtual environment using the state of the art communication and digital multimedia technologies. A virtual collaboration system is being developed under VISNET II network of excellence of the IST FP6 programme. This paper elaborates on a virtual collaboration scenario and proposes content adaptation technologies to fulfil needs of all participants. The proposed content adaptation techniques are based on scalable video coding. The content adaptation based on user preferences, profiles for usage, terminal and network capabilities are discussed. Initial experimental results have been proved to be effective and productive for a virtual office environment.
