This paper provides an overview of MPEG-5 Part 2 Low Complexity Enhancement Video Coding (LCEVC), a novel video coding standard from the MPEG ISO Working Group. The codec is designed for use in conjunction with existing video codecs, leveraging specific tools for encoding "residuals", i.e. the difference between the original video and its compressed representation. LCEVC can improve compression efficiency and reduce the overall computational complexity using a small number of specialized enhancement tools. This paper provides an outline of the coding structure of encoder and decoder, coding tools, and an overview of the performance of LCEVC with regard to both compression efficiency and processing complexity.
