ABSTRACT:
Methods and systems for encoding a video signal into a bit stream, and for reconstructing the video signal from the bit stream are disclosed. In an embodiment of an encoder, an object encoder (22) assigns a symbolic code to an object contained in at least one video frame, wherein the symbolic code identifies a corresponding generic object from a set of generic objects. A difference processor (32), coupled to the object encoder (22), computes a difference signal in dependence upon a difference between the object and the corresponding generic object. A multiplexer (30) provides the bit stream based upon the difference signal and the symbolic code. In an embodiment of a decoder, a demultiplexer (82) extracts a symbolic code and a difference signal from the encoded video signal. The symbolic code identifies a corresponding generic object from a set of generic objects, and the difference signal represents a difference between an object and the corresponding generic object. An object generator (84) forms the video signal by generating the corresponding generic object identified by the symbolic code, and modifying the corresponding one of the generic objects in dependence upon the difference signal.
