Title:
ビデオコーディングのためのサンプルアクセスを伴う線形モデル予測モード
Document Type and Number:
Japanese Patent JP7069171
Kind Code:
B2
Abstract:
Techniques are described of linear model (LM) prediction mode. In one or examples, a video encoder or video decoder may limit the number of neighboring luma samples that are fetched for downsampling thereby increasing the speed at which the video encoder or video decoder is able to complete the LM prediction encoding or decoding.
