1-1. Real-time video transmission between locations using JPEG XS compression @IP Pavilion

At IP Pavilion, three locations in Osaka, Tokyo, and Makuhari were connected via a next-generation network to verify the practicality of real-time transmission of high-quality, low-latency video.

In particular, when communicating between base stations, using uncompressed video using the conventional ST 2110-20 standard has the drawback that the communication bandwidth required for even a single video transmission becomes enormous.

Therefore, we attempted to transmit video using ST 2110-22, using JPEG XS video compression technology, which can significantly reduce communication bandwidth.

Our product, MEP100 *1, was used as a converter to compress four uncompressed video streams on ST 2110-20 broadcasted within the Tokyo base (Sky Perfect JSAT Toyocho) using the JPEG XS method, and transmit the video to Makuhari via ST 2110-22.

*1: MEP100 is a SmartNIC that supports major SMPTE and NMOS standards, and has the functionality to perform protocol processing and JPEG XS encoding/decoding within the FPGA.

　

The diagram above shows the overall system configuration of IP Pavilion.

Macnica is located in the A-sub of SKY Perfect JSAT Toyocho, and compresses the video in the A-sub using JPEG XS and transmits the video to Makuhari Messe in real time.

　

The diagram below shows an overview of video transmission around the MEP100.

SMPTE protocol analysis and JPEG XS encoding/decoding are processed within the FPGA, reducing the load on the server's CPU and GPU.

In addition, by compressing using JPEG XS, it is possible to reduce communication bandwidth while transmitting high-quality video to the point where the difference in image quality is visually indistinguishable.

　

1-2. Video transmission between bases

By performing compression using JPEG XS within the MEP100, we were able to successfully compress the data volume without making the image quality perceptible between before and after compression.

​The four generated ST 2110-22 streams were also transmitted stably to Makuhari Messe.

These results demonstrate that by using the MEP100 as a gateway, broadcast-quality remote production is possible even in a network environment that does not guarantee high bandwidth, such as a dedicated line.

These images and videos show the actual footage transmitted from SKY Perfect JSAT Toyocho to Makuhari Messe.

The video at the point indicated by the arrow is compressed to JPEG XS and transmitted.

2-1. Individual booth exhibition concept

At the IP Pavilion exhibit, real-time video transmission between locations was demonstrated using JPEG XS.

In the individual booth, under the theme of "Macnica Total Solutions that Realize Low-Cost and Flexible Equipment Configuration," we exhibited video transmission and multi-view display using white Box switches, optical transceivers, and MEP100.

The following is an overview of the equipment used in this exhibition and its role.

2-2. Multi-view video

　

The MEP100 has an internal FPGA, so SMPTE standard protocol processing is performed within the FPGA without placing a load on the CPU.

In addition, the CPU and GPU resources used to create a multi-view of the four videos can be selected, allowing for flexible customization of the server's internal configuration.

In this demonstration, four different video streams received from ST 2110 output compatible cameras and file sources were synthesized into a single video within the MEP100, converted into multiview, and output in real time.

This demonstrates that it is possible to build a flexible system using low-cost, general-purpose equipment when transmitting video according to the SMPTE standard, without using expensive dedicated equipment.
