Versatile Video Coding (VVC) is going to be the successor of High Efficiency Video Coding (HEVC). The new standard (currently under development) requires the adoption of tools that provide a good trade-off between gain and implementation complexity. In previous work we proposed a Line-Based Intra Prediction (LIP) algorithm to improve the coding performance of the upcoming standard. However, that contribution did not sufficiently take into account the hardware-related complexity of the method. For this reason, this publication addresses these problems and proposes several modifications of the algorithm to solve them. Experimental results show an average gain of 1.0% and 0.5% for the All Intra (AI) and Random Access (RA) configurations, respectively.
