  • METHOD AND AN APPARATUS FOR PROCESSING A VIDEO SIGNAL
    Publication number: 20220060736
    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.
