Abstract
Methods and apparatus are provided to advantageously improve bit rate control in a video encoder, such as an MPEG video encoder. The targeted bit allocation for a picture to be encoded is advantageously varied based on an occupancy level of a buffer model, such as a video buffer verifier (VBV) buffer model.
