20130128961 | METHOD OF DECODING MOVING PICTURES IN INTRA PREDICTION - A video coding method for encoding a video signal at a low data rate with high video quality is disclosed. To minimize the number of bits required for a residual signal, invalid reference pixels adjacent to a current block are generated using at least one reconstructed valid reference pixel adjacent to the current block. After valid reference pixels adjacent to the current block and the generated reference pixels are filtered, the intra-prediction mode of the current block is determined. Therefore, since a reference block most approximate to the current block is generated, the amount of data needed for the residual block of the current block can be minimized. | 05-23-2013 |
20130128982 | METHOD FOR GENERATING PREDICTION BLOCK IN AMVP MODE - A method for generating a prediction block in Advanced Motion Vector Prediction (AMVP) mode to reconstruct a prediction-coded video signal using a motion vector approximate to original motion information. An AMVP candidate list is generated using effective spatial and temporal AMVP candidates for a current Prediction Unit (PU). If the number of the effective AMVP candidates is smaller than a predetermined value, a motion vector having a predetermined value as a candidate to the AMVP candidate list. Then a motion vector corresponding to an AMVP index of the current PU from among motion vectors included in the AMVP candidate list is determined to be a motion vector predictor of the current PU. | 05-23-2013 |
20130136183 | APPARATUS FOR DECODING MOTION INFORMATION IN MERGE MODE - Disclosed is an apparatus for decoding motion information in merge mode for reconstructing a moving picture signal coded at a low data rate while maintaining a high quality of an image.
