Abstract

The invention relates to a device (100) for intra-predicting pixel values ​​of pixels of a current video coding block of a frame of a video signal based on a plurality of reference pixel values ​​of a plurality of reference pixels. The apparatus (100) comprises an intra prediction unit (103) configured to perform intra prediction on a pixel value of a current pixel of the current video encoding block based on: a first reference pixel among the plurality of reference pixels A first reference pixel value of a pixel, wherein the first reference pixel is located in a first adjacent video coding block; a second reference pixel value of a second reference pixel among the plurality of reference pixels, wherein the second reference a pixel located in a second adjacent video coding block; a distance between the current pixel and the first reference pixel, and a distance between the current pixel and the second reference pixel.

Description

technical field [0001] The invention relates to the field of video coding and decoding. More particularly, the present invention relates to an apparatus and method for intra-prediction of a video encoding block, and an encoding apparatus and a decoding apparatus including such an intra-prediction apparatus. Background technique [0002] Digital video communication and storage applications are implemented by a wide variety of digital devices such as digital cameras, cellular radiotelephones, notebook computers, broadcast systems, video conferencing systems, and the like. One of the most important and challenging tasks faced by these applications is video compression. The task of video compression is complex and limited by two conflicting parameters: compression efficiency and computational complexity. Video coding standards such as ITU-T H.264 / AVC or ITU-T H.265 / HEVC better balance these parameters. For this reason, support for these video coding standards is almost a mand...
