Abstract: The invention adjusts the quality level of applications (typically real time media such as video), in applications such as video conferencing and streaming. A model of the cognitive focus of user attention is fed information such as gaze/eye tracking, open and in focus application windows, presence in a room (see Fig. 3) and so forth in order to determine user attention 202. Actual quality of service (QoS) (e.g. data rate) is determined for programs 204. A perceived QoS (pQoS) is determined using the determined user attention 206 and thence the invention determines allowable adjustments to the actual QoS which will maintain the same perceived QoS 210 and applies them to the application. The invention allows efficient use of network bandwidth whilst maintaining a perceived quality of service for the user.
