Abstract: Binary tree split mode coding is performed while encoding digital video image blocks using a quad tree plus binary tree coding. The quadtree split can be represented by some combinations of horizontal and vertical binary tree split. Blocks are constrained to be split down to a minimum block size and with certain split constraints such that some redundant tree structures are avoided. Redundant syntax in coding the binary tree split mode syntax element is removed to provide coding efficiency.

Abstract: A method of performing intra prediction for encoding or decoding uses multiple layers of reference samples. The layers are formed into reference arrays that are used by a function, such as a weighted combination, to form a final prediction. The prediction is used in encoding or decoding a block of video data. The weights can be determined in a number of ways, and for a given prediction mode, the same weights, or different weights can be used for all pixels in a target block. If the weights are varied, they can depend on the distance of the target pixel from reference arrays.

Abstract: An apparatus (20) and method (10) for rendering a tree structure in a GUI depending on a position of a pointing cursor relative to the rendered tree use the cursor position with respect to the tree to control which tree branches to expand/collapse automatically. They reconfigure the tree view for compact presentation without need for explicit expand/collapse operations. A tree view is generated (11). A cursor position relative to the view is determined (14), consisting of first and second position values according to first and second directions. The branch the cursor position is aligned with according to the first direction is automatically selected as active branch (15). Sub-levels of that branch to be expanded are determined (16), depending on the second position value relative to indentations of the sub-levels, and the tree view is automatically updated by expanding the determined sub-levels of the active branch and collapsing other branches (17).

Abstract: An improved method of performing intra prediction for encoding or decoding uses interpolation such that substitute samples are found for samples to be used in the interpolation calculation that lie outside a normal reference range. The substitute samples can be repeated end samples from the bottom of a reference portion to the left of the target block, or right samples of a reference portion above the target block. An encoder can signal to a decoder whether to use intra prediction or interpolation prediction.

Abstract: In omnidirectional videos, a straight line in the rendering space may no longer appear as a straight line in the frame to be encoded, due to the projection between the encoding space and the rendering space. To adapt to the geometry of omnidirectional videos, intra prediction is performed along non-straight curves. In particular, references samples in neighboring reconstructed blocks of a current block are copied along non-straight curves to form a predicted block for the current block. The non-straight curves may be computed online based on a single intra prediction directional mode for the current block. The parameters of non-straight curves may be based on the mapping used in forming the omnidirectional videos, and the location/size of the current block. The non-straight curves may be obtained using a look-up table or an analytical function that is dependent on the location and size of the current block.
