摘要: The present invention relates to a method and apparatus for encoding or decoding a video signal. The method for processing a video signal according to the present invention determines the type of a block in accordance with the information which indicates whether to partition or merge the current block, acquires predicted values of each sub-block using restored peripheral pixels for each sub-block, and restores the current block using the acquired values. Here, pixels used for acquiring predicted values may include restored pixels for other sub-blocks contained in the current block, and the type of sub-blocks can be taken into account in a prediction mode for acquiring predicted values.

摘要: New intra angular prediction modes and methods for decoding are offered for providing greater accuracy when processing predictions of digital video data blocks. One new method considers predicting a current prediction sample by taking the linear interpolation of two previously reconstructed reference samples that lay along a common angular line. Another new method offers a method for making previously unavailable samples from a neighboring block available as reference samples when predicting a current prediction sample. Another new method considers a new combined intra prediction mode that utilizes a local mean to predict a current prediction sample. And a new decoding method offers to rearrange the order in which video data blocks are predicted based on the intra prediction mode used for predicting the video data blocks.
