FIELD: information technology.
SUBSTANCE: apparatus and method for highly scalable intraframe video coding are disclosed. Conventional macroblock discrete cosine transform (DCT) tools are integrated with the subband filter banks for improved efficiency of scalable compression. Enhancement layers are represented in a subband domain and coded by an inter-layer frame texture coder utilising an inter-layer prediction signal formed by the decoded previous layer. Each quality enhancement layer is additionally scalable in resolution.
EFFECT: improved efficiency of a combined coding system.
