Abstract: ABSTRACT CROSS COMPONENT DETERMINATION OF CHROMA AND LUMA COMPONENTS OF VIDEO DATA This application is directed to decoding video data including a plurality of luma components of a plurality of pixels in a video frame. The plurality of pixels belong to a coding block (506), and include a boundary pixel that is inside the coding block (506), wherein the boundary pixel is immediately adjacent to a boundary of the coding block. One or more neighboring pixels of the boundary pixel are outside of the coding block and determined as being not available. A luma component corresponding to the boundary pixel is assigned to a respective luma component corresponding to each of the one or more neighboring pixels. A boundary luma component is determined based, at least, on the luma components of the one or more neighboring pixels and the boundary pixel according to a predefined luma interpolation scheme. A boundary chroma component is converted from the boundary luma component according to a linear mapping model.
