Media processing in software enables consumer terminals to become open and flexible. Because consumer products are heavily resource constrained, this processing is required to be cost-effective. Our QoS approach aims at cost-effective media processing in software. QoS resource management is based on multilevel control, corresponding to different time-horizons, and resource allocation below worst-case using periodic budgets provided by a budget scheduler.Multilevel control combined with budgets below worst-case gives rise to a problem related to user focus. Upon a sudden increase in load of an application with user focus, its output will have a quality dip. To resolve this user focus problem, we present the novel concept of a conditionally guaranteed budget (CGB). A feasible extension of our budget scheduler with CGBs is briefly described.
