Claim Text:
1. An apparatus, comprising: an encoder for encoding picture data for at least a portion of a picture, wherein said encoder derives an intra mode to apply to the portion from neighboring template data and abstains from explicitly signaling the intra mode for the portion, the neighboring template data corresponding to a neighboring template formed from neighboring pixels with respect to the portion, and wherein the intra mode for the portion is implicitly derived from a subset of a set of available intra modes, and not an entirety of the set, by using the neighboring template data to test a particular intra mode within the subset based upon a least distortion measure from among respective distortion measures, said least distortion measure being performed for a particular intra mode between predicted values and said neighboring template data, wherein the predicted values and said neighboring template data correspond to a candidate neighborhood with respect to the portion; and wherein said neighboring template comprises a neighboring patch with respect to said portion, and wherein said neighboring patch includes already decoded pixels.
