This paper describes a hardware implementation of HEVC (High Efficiency Video Coding) video encoder for exploring performance of HEVC in real-time applications. By optimizing hardware architecture and developing fast mode decision algorithms, our FPGA-based prototype can encode 1080p, 10-bit video at 60fps in real-time. Both objective and subjective(More)
This paper describes the world's first HEVC (High Efficiency Video Coding) hardware encoder for SHV (Super Hi-Vision). SHV is an 8K UHDTV (Ultra-High Definition Television) system that has a 7,680 × 4,320 pixel resolution. The developed encoder compresses SHV pictures in real-time using 17 encoding units. The coded picture provides acceptable level(More)
This paper introduces the world’s first video and audio codec system that complies with 8K broadcasting standards and describes transmission experiments via a broadcasting satellite using this system. 8K Super Hi-Vision (8K) is a broadcasting system capable of highly realistic 8K Ultra High Definition Television (UHDTV) video and 22.2 multichannel audio.
