Abstract

The interest developed in the last years on the coded representations of video signals allowing independent manipulation of semantic picture elements has become one of the guidelines for the new ISO standard MPEG-4. The real-time generation of a bit-stream according to this new paradigm, which can be described as the multiplexing of a set of independently coded, arbitrarily shaped video objects, poses new requirements regarding the transmission through either fixed of variable-rate channels. In particular, adequate control algorithms should support the encoding of objects with different quality requirements and be robust with respect to rapid changes in size and shape of the objects. After formalizing this new rate-control problem in terms consistent with the previous requirements, this paper focuses on the design of the corresponding rate-control algorithms in the real-time case, introducing and evaluating an approach relying on the modelization of the source and the application of optimization criteria based on rate-distortion concepts for the tuning of the different object qualities. The experimental work presented, which corresponds to the recent MPEG-4 Video Verification Model coder especification, appart from making apparent the superiority of the global control over the individual control of the coding of each object, allows for a comparison of the advantages and inconveniences of the different optimization objectives.
