For an open and flexible system that is robust and cost-effective, it is proposed to use scalable video algorithms (106, 109, 110, 112, 113, 114, 306, 308, 406, 408). Scalable video algorithms (106, 109, 110, 112, 113, 114, 306, 308, 406, 408) can dynamically trade resource usage with visual output quality. In such a system both the visual output quality and the resource usage may change at run-time leading to unpredictable behaviour of the system. A novel approach that assists in the predictability of an open and flexible system is proposed. The idea is that by knowing the parameters that influence the output quality and load of some video algorithms (106, 109, 110, 112, 113, 114, 306, 308, 406, 408), by appropriately measuring them and by providing the necessary information (316, 320, 416, 420, 426, 427) to the system control (321, 421), the system control (321, 421) can react sooner and do the appropriate changes (317, 322, 323, 417, 422, 423), leading to a predictable system.
