Abstract
A quantization level is selected for the current video frame in accordance with a plurality of mappings, wherein each mapping correlates an activity measure with a bits per frame measure and each mapping corresponds to a quantization level of a plurality of quantization levels. The current video frame is encoded in accordance with the selected quantization level.
