Abstract
Systems, apparatuses and methods whereby a base coded video signal is provided to a decoder having a set of post-processing stages. The base coded video signal can be decoded to produce a base decoded video signal. Post-processing of the base decoded video signal can be used to produce an enhanced quality video output signal. Application of a post-processing stage can be implemented according to the capabilities of the decoder and/or the instantaneous operating parameters of the decoder and/or characteristics of a display. A control signal, communicated over a dedicated channel separate from the base coded video signal, can be used initiate and/or aid implementation of a post-processing stage. The control signal can also provide information to assist/manage the decoding of the base coded video signal. The use of additional post-processing stages increases the complexity of an overall decoding process while improving the quality of a resulting reproduced video sequence.
