    Abstract: The present invention relates to a method for decoding a video signal, comprising the steps of: acquiring a transform size flag of the current macroblock from a video signal; checking the number of non-zero transform coefficients at each pixel position in a first transform block which corresponds to the transform size flag; changing a scan order of the first transform block by prioritizing the position of the pixel having the greatest number of the nonzero transform coefficients in the first transform block; determining the number of the non-zero transform coefficients at each pixel position in a second transform block, and setting the changed scan order of the first transform block as an initialized scan order of the second transform block; adding the number of the non-zero transform coefficients at each pixel position in the first transform block and the number of the non-zero transform coefficients at each pixel position in the second transform block, and changing the scan order of the second transform block by prioritizing the position of the pixel having the greatest number of the nonzero transform coefficients; and decoding the transform coefficients arranged in the scan order changed in the previous step, wherein the first transform block and the second transform block have sizes corresponding to the transform size flag, and are contained in the current macroblock.

    Abstract: A method and a device used in an optical wireless communication (OWC) system are provided. A transmitting terminal transmits a plurality of reference signals to a receiving terminal through each of a plurality of beams. Each of the plurality of beams may have an inhomogeneous polarization beam pattern. The receiving terminal measures signal strength and polarization with respect to the plurality of reference signals. When the receiving terminal transmits feedback information including the measured signal strength information and polarization information to the transmitting terminal, the transmitting terminal may select at least one beam among the plurality of beams on the basis of the feedback information. Alternatively, the receiving terminal may select at least one beam from among the plurality of beams, which corresponds to at least one inhomogeneous polarization beam pattern among a plurality of inhomogeneous polarization beam patterns, on the basis of the measured signal strength and polarization.

    Abstract: A video decoding method according to the present document comprises the steps of: configuring an MPM list by deriving candidate intra prediction modes on the basis of a first neighboring block located on the left side and a second neighboring block located on the upper side with respect to the current block; deriving an intra prediction mode for the current block on the basis of the MPM list; generating prediction samples for the current block on the basis of the intra prediction mode; and generating a reconstructed picture for the current block on the basis of the prediction samples, wherein a first intra prediction mode of the first neighboring block and a second intra prediction mode of the second neighboring block are the same, wherein the candidate intra prediction modes including a DC mode are derived on the basis of a case where both the first intra prediction mode and the second intra prediction mode are the DC mode.

    Abstract: According to embodiments described herein, sub-pictures and/or virtual boundaries can be used for coding an image. For example, sub-pictures in the current picture can be used for predicting, reconstructing, and/or filtering the current picture. Virtual boundaries can be used for filtering reconstructed samples of the current picture. Through image coding based on the subpictures and/or virtual boundaries according to embodiments described herein, the subjective/objective quality of an image can be improved, and the consumption of hardware resources necessary for the coding can be reduced.
