SUMMARY Beyond 5G is the next generation mobile communication system expected to be used from around 2030. Services in the 2030s will be composed of multiple systems provided by not only the conventional networking industry but also a wide range of industries. However, the current mobile communication system architecture is designed with a focus on networking performance and not oriented to accommodate and optimize potential systems including service management and applications, though total resource optimizations and service level performance enhancement among the systems are required. In this paper, a new concept of the Beyond 5G cross-industry service platform (B5G-XISP) is presented on which multiple systems from different industries are appropriately organized and optimized for service providers. Then, an architecture of the B5G-XISP is proposed based on requirements revealed from issues of current mobile communication systems. The proposed architecture is compared with other architectures along with use cases of an assumed future supply chain business.

SUMMARY This paper describes a novel 4K 120fps (frames per sec- ond) real-time HEVC (High E ffi ciency Video Coding) encoder for high-frame-rate video encoding and transmission. Motion portrayal problems such as motion blur and jerkiness may occur in video scenes containing fast-moving objects or quick camera panning. A high-frame-rate solves such problems and provides a more immersive viewing experience that can express even the fast-moving scenes without discomfort. It can also be used in remote operation for scenes with high motion, such as VAR (Video Assistant Referee) systems in sports. Real-time encoding of high-frame-rate videos with low latency and temporal scalability is required for providing such high-frame-rate video services. The proposed encoder achieves full 4K / 120fps real-time encoding, which is twice the current 4K service frame rate of 60fps, by multichip configuration with two encoder LSI. Exchange of reference picture data near a spatially divided slice boundary provides cross-chip motion estimation, and maintains the coding e ffi ciency. The en- coder supports temporal-scalable coding mode, in which it output stream with temporal scalability transmitted over one or two transmission paths. The encoder also supports the other mode, low-delay coding mode, in which it achieves 21.8msec low-latency processing through motion vector restriction. Evaluation of the proposed encoder’s multichip configuration shows that the BD-bitrate (the average rate of bitrate increase), compared to simple slice division without inter-chip transfer, is − 2 . 86% at minimum and − 2 . 41% on average in temporal-scalable coding mode. The proposed encoder system will open the door
本文介绍了一种用于高帧率视频编码和传输的新型4K 120fps(帧每秒)实时HEVC (High E efficient Video Coding)编码器。在包含快速移动物体或快速摄像机平移的视频场景中，可能会出现运动模糊和抖动等运动描绘问题。高帧率解决了这些问题，并提供了一种更加身临其境的观看体验，即使是快速移动的场景也可以毫无不适地表达出来。它还可以用于高动作场景的远程操作，例如体育比赛中的VAR(视频助理裁判)系统。提供高帧率视频服务需要对高帧率视频进行实时编码，具有低延迟和时间可扩展性。该编码器通过多芯片配置两个编码器LSI，实现了4K / 120fps的全实时编码，是目前4K服务帧率60fps的两倍。在空间分割的切片边界附近交换参考图像数据提供了跨片运动估计，并保持了编码效率。该编码器支持时间可伸缩的编码模式，其输出流具有时间可伸缩性，可以通过一条或两条传输路径传输。编码器还支持另一种模式，即低延迟编码模式，通过运动矢量限制实现21.8msec的低延迟处理。对所提出的编码器的多芯片配置的评估表明，与没有芯片间传输的简单切片分割相比，bd比特率(比特率增加的平均速率)为−2。最小为86%，最小为- 2。在时间可伸缩的编码模式下平均为41%。提出的编码器系统将打开这扇门
