    摘要: In one example, an apparatus is disclosed for coding coefficients associated with a block of video data during a video coding process, the apparatus comprising a video coder configured to code information that identifies a scanning order associated with the block, wherein to code the information that identifies the scanning order associated with the block, the video coder is configured to determine a most probable scanning order for the block, and code an indication of whether the scanning order associated with the block is the most probable scanning order. In another example, to code the information that identifies the scanning order associated with the block, the video coder is further configured to, in the event the scanning order associated with the block is not the most probable scanning order, code an indication of the scanning order associated with the block.

    摘要: An apparatus is disclosed for coding coefficients associated with a block of video data, including a video coder configured to code information that identifies a first scanning order associated with the block if a position of any of one or more of the coefficients within the block, starting with a first coefficient within the block and ending with a last non-zero coefficient within the block according to the first scanning order, and proceeding according to the first scanning order, according to the first scanning order is different than a position of the respective coefficient within the block according to a second scanning order, and avoid coding the information if the position of each of the one or more of the coefficients within the block according to the first scanning order is the same as the position of the respective coefficient within the block according to the second scanning order.

    摘要: A video encoder may transform residual data by using a transform selected from a group of transforms. The transform is applied to the residual data to create a two-dimensional array of transform coefficients. A scanning mode is selected to scan the transform coefficients in the two-dimensional array into a one-dimensional array of transform coefficients. The combination of transform and scanning mode may be selected from a subset of combinations that is based on an intra-prediction mode. The scanning mode may also be selected based on the transform used to create the two-dimensional array. The transforms and/or scanning modes used may be signaled to a video decoder.
