Screen Content Coding (SCC) and HEVC‑SCC Tools: Principles and Performance Gains

Screen Content Coding (SCC) extends HEVC with four specialized tools—Intra Block Copy, Palette Mode, Adaptive Color Transform, and Adaptive Motion Vector Resolution—yielding typical BD‑Rate reductions of up to 19 % for screen‑rich video, though at increased encoder complexity, and is now widely used in cloud environments while mobile adoption remains limited.
