Claim 18:
19. A method for controlling a bit rate for encoding a signal, wherein the signal is encoded using at least two distinct encoding algorithms, the method comprising:
decomposing an uncompressed frame of a signal into at least two components, wherein the uncompressed frame is a single frame, and wherein decomposing the single frame into the at least two components is performed via a predetermined filter operation involving a filter, said filter being applied to the single frame;
allocating an overall bit rate to the at least two components of the signal, wherein:
a first component of the signal is to be encoded using a first encoding algorithm implemented by a first encoder,
the first component is an unfiltered version of the single frame,
a second component of the signal is to be encoded using a second encoding algorithm implemented by a second encoder, and
the second component is a filtered version of the single frame;

causing a first feedback signal to be directly provided from the first encoder to a selection unit;
selecting, using the selection unit, the first and second encoding algorithms;
causing a second feedback signal to be directly provided from the second encoder to the selection unit; and
determining, by the selection unit and based on the first and second feedback signals, which portion of the overall bitrate is to be allocated to the first component and to the second component.
