N2 - In this paper, a novel screen content (SC) transcoding framework is presented to efficiently bridge High Efficiency Video Coding (HEVC) and its Screen Content Coding (SCC) extension and support the bitstream backward-compatibility over legacy HEVC devices. Based on the side information analysis of SCC bit-stream, fast mode and partition heuristics are designed to accurately determine the mapping between novel SCC modes and conventional HEVC modes. Compared with the trivial SCC-HEVC transcoding solution, the proposed framework achieves a 42% re-encoding complexity reduction over standard JCT-VC screen content sequences with only 0.52% negligible BD-Rate loss under All-Intra (AI) configuration.
