abstract = "Multiple reference line (MRL) intra prediction allows to use reference lines not necessarily immediately adjacent neighboring line or column in generating intra predictor. Compared to MRL already existing in the versatile video coding (VVC) standard which can use a total of three reference lines including the adjacent one, the MRL under discussion now in enhanced compression beyond VVC is extended to use a total of six reference lines. However, its MRL candidates are listed in a fixed order for all blocks without considering non-identical effectiveness of each reference line in intra prediction. In this paper, we propose a reordering scheme of the MRL candidate lines in the MRL list considering similarities between predictors generated by available reference lines. According to our experimental results, the proposed method is shown to achieve an overall coding gain of -0.02\% in luma channel over the enhanced compression model (ECM) 5.0 under the all intra (AI) configuration of the common test condition (CTC).",
