Abstract
A method of scaling complexity of a video processing system including determining a power saving factor based on an operating parameter and adjusting processing of video information based on the power saving factor to reduce computation complexity. The operating parameter may include available power and/or available processing capacity. A method of complexity scalability for a video processing system using prioritized layered coding including determining a power saving factor based on one or more metrics, such as power capacity and/or available processing capacity, and reducing processing complexity of multiple prioritized coding functions in a predetermined order of priority based on the level of the power saving factor. A video processing system including a power management circuit which determines the power saving factor and a video encoder system which correspondingly adjusts computation complexity.
