The Required Video Bitrate for 8K120-HZ Real-time Temporal Scalable Coding

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 decode 60-Hz video frames from compressed 120-Hz...

Summary: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 decode 60-Hz video frames from compressed 120-Hz bit-streams. To evaluate the image quality of our encoder, we conducted subjective evaluation experiments for 8K 60-Hz and 120-Hz videos. From the results, we find that the required bitrate for 8K 120-Hz videos is 85 Mbps.
