Abstract
Successive frames in a video sequence are encoded by a video encoder. The bits are apportioned among successive frames to maximize overall perceived video quality when the encoded video sequence is decoded and displayed. The ongoing allocation process is constrained by the need to avoid decoder buffer exception, i.e., buffer underflow and overflow conditions, at the decoder.
