ABSTRACT:
Methods of adaptively encoding a sequence of frames of image information resenting multiple video objects in which the video object information is digitally encoded as to texture, motion and shape characteristics to produce code bits at a variable rate for transmission via a buffer having a fixed bit rate output, and a target number of bits is estimated for encoding video objects in a video object plane and the target is distributed and quantization parameters are adjusted according to header bits associated with a previous frame.
