After having split each of the samples of the picture into at least two sub-samples, each of the at least two sub-samples being of a predetermined bit-depth, the bit-depth of the samples being higher than the bit-depth of each of the at least two sub-samples, the at least two sub-samples of each of the samples are stored into at least two different components of at least one picture. | 2015-01-08 |

20150010070 | METHOD AND APPARATUS FOR DECIDING A VIDEO PREDICTION MODE - A method and an apparatus for deciding a video prediction mode are provided. The method includes providing n prediction modes, where n is a positive integer, selecting first prediction modes among the n prediction modes using a first cost function, and selecting a final prediction mode among the first prediction modes using a second cost function different from the first cost function. The first cost function includes a sum of absolute transformed difference (SATD) operation, and the second cost function includes a sum of squared difference (SSD) operation. | 2015-01-08 |
20150010071 | BASE COLOR MERGING FOR MULTI-STAGE BASE COLOR AND INDEX MAP (MBCIM) FOR REXT - An enhancement for removing signaling redundancy of base color within multi-stage base color and index map (MBCIM) processing of HEVC for computer generated screen content is presented. Redundancy is removed in response to determining and setting merge flags when neighboring pixels are coded and available. During coding of pixels in the current CU, then color are copied from the neighboring blocks when a merge flag is set, or the pixel is coded as it was previously. | 2015-01-08 |
20150010072 | METHOD AND APPARATUS FOR UNIFICATION OF COEFFICIENT SCAN OF 8X8 TRANSFORM UNITS IN HEVC - A method and apparatus for processing 2N×2N transform units (TUs) are disclosed. In one embodiment, the method comprises determining a first-layer scanning order among four N×N sub-blocks of the 2N×2N TU; determining a second-layer scanning pattern for said four N×N sub-blocks; and providing scanned 2N×2N transform coefficients of the intra-coded or the inter-coded 2N×2N TU using double scanning based on the first-layer scanning order and the second-layer scanning pattern. In another embodiment, said determining the first-layer scanning order is dependent on the second-layer scanning pattern. The second-layer scanning pattern can be diagonal, horizontal or vertical. In an embodiment, the first-layer scanning order can be from an upper-left sub-block, to an upper-right sub-block, to a lower-left sub-block and to a lower-right sub-block for the second-layer horizontal scanning pattern and from an upper-left sub-block, to a lower-left sub-block, to an upper-right sub-block and to a lower-right sub-block for other second-layer scanning patterns. | 2015-01-08 |
