Abstract:
Method and apparatus for intra prediction in video encoding and decoding A method and an apparatus for video encoding and decoding, and more particularly, a method and an apparatus for performing intra prediction using reference sample portion having a thickness of at least two pixels and intra prediction modes based on such reference sample portion The intra-prediction mode may specify a direction and a propagation model for determining the manner of propagating samples in the prediction block. Using a reference sample portion having a thickness of at least two pixels allows the variations in the pixel values to be used in propagating the samples in the prediction block.

Claim (Index 9):
An apparatus, comprising:\n a memory configured to store a picture to be decoded; a processor, coupled to the memory, and configured to: access a prediction block in the picture to be decoded and data indicative of an intra-prediction mode associated with the prediction block; access a reference sample layer around the prediction block in the picture to be decoded, the reference sample layer comprising at least two adjacent columns or rows in the causal neighborhood of the prediction block; and generate a predicted value for each pixel within the prediction block based the values of at least 2 pixels in the reference sample layer along a direction of prediction specified by the intra-prediction mode associated with the prediction block.
