ABSTRACT:
Multi-layered motion or still video compression includes, in an encoder or encoding function aspect of the invention, separating the video signal into low-frequency and high-frequency components, processing the low-frequency components of the video signal to generate synthetic high-frequency components, the low-frequency components or a data reduced version of the low-frequency components comprising a main or base layer, and generating the difference between the synthetic high-frequency components and the actual high-frequency components, the difference comprising an error or enhancement layer signal. A decoder or decoding function aspect of the invention processes the main layer to generate synthetic high-frequency components and combines the synthetic high-frequency components, main layer and enhancement layer to provide a decoded output signal similar to the video signal applied to the encoder.
