Abstract: We developed a JPEG-XS codec-based video transmission system corresponding to 8K UHDTV (Fig. 1). JPEG XS has attracted attention as a mezzanine compression technology for IP interfaces such as SMPTE ST 2110-22. JPEG-XS is known for its high compression efficiency, picture quality, and very low latency, but there have not been any products adapted to 8K formats to date. — In contrast, migration of interfaces from SDI to IP in program production facilities such as TV studios or OB vans is accelerating. It is important to define a network design starting with its bitrate per stream, especially in large-scale production systems, because the quantity of network switches and bandwidth in a backbone network design greatly affects development costs, system complexity, and feasibility. — We developed an 8K JPEG-XS software-based codec prototype using only a CPU and not GPU, with which we were able to confirm 8K/60p video quality in real time at various compression ratios. For higher flexibility, the decoder can decode an 8K resolution image by using the full bit stream, or a 4K resolution image by decoding only parts of the bit stream. In terms of efficient system design, we gave it a scalable decoding function, which can also achieve 4K-resolution video, by partially using an 8K code stream. — In this paper, we will introduce the results of the quality evaluations and propose an appropriate bitrate for the 8K JPEG-XS case. Furthermore, we will refer to an example of network design, where it is used in a large-scale, multi-resolution production system for which we are doing such evaluations.
