  • METHOD AND AN APPARATUS FOR PROCESSING A VIDEO SIGNAL
    Publication number: 20160065986
    Abstract: A method of processing a video signal is disclosed. The present invention includes obtaining a current macroblock type, obtaining skip or direct mode indication information on a partition of the current macroblock according to the current macroblock type, deriving a motion vector of the partition according to the skip or direct mode indication information, and predicting a pixel value of the partition using the motion vector. Accordingly, the present invention obtains a pixel value of a reference block close to an original video using a motion vector, thereby enhancing a reconstruction ratio of the macroblock. As a macroblock uses skip or direct prediction indication information, it is unnecessary to separately code skip mode indication information and direct mode indication information on the macroblock, whereby an information size to be coded can be reduced.

  • Method and apparatus for processing video signals using boundary intra coding
    Patent number: 9196059
    Abstract: A boundary intra coding flag is obtained according to a current macroblock type. When the boundary intra coding flag indicates that the current macroblock is coded in an intra prediction mode using boundary intra coding, boundary coding information is obtained, and a boundary in the current macroblock is induced based on the boundary coding information. Therefore, the regions divided by the boundary can be coded in the intra prediction mode. The accuracy of a predicted pixel value can be improved by performing the intra prediction for regions divided by the boundary. Accordingly, the residual data transmitted to a decoder can be reduced.
