A method and system are provided in which a device can determine, for a current block of pixels, a first intra-prediction based on reconstructed neighboring pixels and a second intra-prediction based on a pattern match with a reconstructed block of pixels. One of the two intra-predictions may be selected to generate a compressed bit stream comprising information of the current block of pixels. The intra-prediction selection may be performed on a block-by-block basis. An indication may be generated as to which of the two intra-predictions was selected for a particular block of pixels. When pattern matching is selected, a positional relationship of the reconstructed block of pixels with the matching pattern may be encoded and embedded into the compressed bit stream. The same device or another device may be operable to receive a compressed bit stream comprising intra-prediction selection and/or positional relationship information to reconstruct a current block of pixels.
