  • Coding method and coding apparatus
    Patent number: 8331704
    Abstract: Provided are methods and apparatuses for coding a motion vector by a multimedia image codec. The method including: calculating and storing difference vectors which represent differences between adjacent motion vectors of image data; selecting a central axis of the stored difference vectors based on trend information of the difference vectors; transforming the difference vectors based on the central axis of the difference vectors; and performing bit coding using the axis-transformed difference vectors.

  • De-blocking filter and method for de-blocking filtering of video data
    Publication number: 20090180700
    Abstract: Disclosed is a method and apparatus for de-blocking filtering of video data. The method includes performing Integer Transform (IT) of an input data block, scaling the data block, which has been IT-ed and indicates a frequency domain, by applying a modified scaling matrix in which a high frequency area is set to 0, performing Inverse Integer Transform (IIT) on the scaled block.
