The Joint Video Exploration Team (JVET) has been developing an emerging standard Versatile Video Coding (VVC), which includes screen contents as one of its requirements. Intra block copy (IBC) and palette coding are the two powerful coding tools for screen content coding. In this paper, a compound palette mode is proposed to exploit the advantages of both IBC and palette coding, which allows samples to be reconstructed by either IBC predictions or palette entries. The proposed method is evaluated with VVC reference software VTM4 on typical sequences containing "text and graphics with motion". Experimental results report significant coding gain that the proposed scheme can achieve 7.80% and 1.03% BD-rate savings under AI conditions on average when compared with VTM4 and the existing palette scheme.
