Abstract: The present disclosure discloses an apparatus and method for providing compensation information, which compress the compensation information for demura and a display driving apparatus for solving a defect in a screen by using compressed compensation information. The apparatus for providing compensation information includes a compensation value provision unit configured to provide compensation values of pixels and a compression unit configured to perform compression on the compensation values for each block of a screen.

Abstract: In one embodiment, a method includes the steps of receiving, from a client device, a first viewpoint from which to view a virtual object, the virtual object having a shape defined by multiple geometric primitives, identifying, relative to the first viewpoint, visible geometric primitives from multiple geometric primitives, allocating a region in a texture atlas for each of the visible geometric primitives, generating shading information for each of the visible geometric primitives, storing the shading information of each of the visible geometric primitives in a portion of the allocated region smaller than the allocated region to create a buffer around the portion of the allocated region where the shading information is stored, and sending, to the client device, the texture atlas and a list identifying the visible geometric primitives, the texture atlas being configured for rendering images of the visible geometric primitives from different viewpoints.

Abstract: According to an embodiment, an encoding device includes an index setting unit and an encoding unit. The index setting unit generates a common index in which reference indices of one or more reference images included in a first index and a second index are sorted in a combination so as not to include a same reference image in accordance with a predetermined scanning order. The first index representing a combination of the one or more reference images referred to by a first reference image. The second index representing a combination of the one or more reference images referred to by a second reference image. The encoding unit encodes the common index.

Abstract: A method for encoding pictures within a groups of pictures using prediction, where a first reference picture from a group of pictures and a second reference pictures from the subsequent group of pictures are used in predicting pictures in the group of pictures associated with the first reference picture. A plurality of anchor pictures in the group of pictures associated with the first reference picture may be predicted using both the first and second reference pictures to ensure a smooth transition between different groups of pictures within a video frame.
