Abstract
The invention is related to methods and apparatus that advantageously improve picture quality in a video encoder, such as an MPEG video encoder. Scene changes typically occur relatively frequently in picture sequences, such as movies. One embodiment of the invention detects a scene change within a group of pictures and allocates bits within the group of pictures in response to the detected scene change without changing a predetermined structure for the group of pictures.
