This article describes a real-time HEVC (High Efficiency Video Coding) encoder operating at 120 frames per second (fps) that is designed to achieve higher frame rate video services. The encoder achieves 4K/120 fps video encoding in real time through the synchronized operation of multiple 2K/120 fps encoders working in parallel. This encoder also makes it possible to achieve temporal scalable coding and transmission with upward compatibility for existing 60 fps based systems. This temporal scalability is expected to contribute to rapid expansion of the high frame rate video service field. The proposed encoder systems will also open the door to next-generation high frame rate ultra-high definition television services.
