摘要: The present invention relates to the encoding and decoding of image information. According to the present invention, the decoding method comprises the steps of: entropy-decoding received information; performing inter prediction on a current block based on the entropy-decoded information; and restoring images by using the prediction results, wherein, in the inter prediction step, a skip mode or merge mode is applied to the current block and movement information of the current block may be determined based on the movement information of a neighboring block of the current block.

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.

摘要: Disclosed are a method for partitioning a block and a decoding device. A method for decoding an image comprises the steps of: partitioning one prediction unit, in which an intra prediction is performed in a predetermined intra prediction mode, into a plurality of transform units; and performing the intra prediction for each of the plurality of the transform units on the basis of the predetermined intra prediction mode. Thus, the invention increases the image encoding efficiency.

摘要: New intra planar modes are introduced for predicting digital video data. As part of the new intra planar modes, various methods are offered for predicting a first sample within a prediction unit, where the first sample is needed for referencing to when processing the new intra planar modes. And once the first sample is successfully predicted, the new intra planar modes are able to predict a sample of video data within the prediction unit by processing a bi-linear interpolation of four previously reconstructed reference samples.
