The new Versatile Video Coding Standard (VVC) was finalized in July 2020. This new international standard is able to provide a higher compression efficiency by up to 50% for the same subjective quality compared to its predecessor HEVC but at the cost of an increased computational load. This paper investigates the complexity of VVC decoder processing blocks and presents a highly optimized decoder implementation that can achieve 4K 60fps VVC real-time decoding on an x86 based CPU using SIMD instruction extensions of the processor and additional parallel processing including data and task-level parallelism.
