This paper introduces the world’s first ultrahigh-definition (UHD)-2/8K 120-Hz high-efficiency video coding (HEVC)/H.265 realtime video codec that complies with 8K broadcasting standards in Japan. The validation results of the processing performanc

8K video parameters were designed to provide an immersive experience; meanwhile, special considerations are necessary to assess the entire screen subjectively. This paper studies the video bit-rate required for 8K 119.88-Hz (120-Hz) and 59.94-Hz (60-

We developed an 8K 119.88-Hz (120-Hz) the high efficiency video coding (HEVC)/H.265 encoder to transmit smoother videos. To ensure backward compatibility with 59.94-Hz (60-Hz) video decoders, the encoder supports temporal scalable coding to partially

Inter-frame prediction in video coding can be difficult if an object is sharped or blurred between inter frames. We therefore propose a video coding method for inter-frame prediction using super-resolved and blurred decoded pictures. In the joint exp

This paper studies the video bit-rate required for 8K 119.88 Hz (120 Hz) high efficiency video coding (HEVC)/H.265 temporal scalable coding that can partially decode 59.94 Hz (60 Hz) video frames from compressed 120 Hz bit-streams. We compress 8K 120
