Shanghai Media Tech and Media Links Verify 4K UHD over IP for Remote Production

Shanghai Media Tech Co. and Media Links recently teamed up to evaluate a 4K UHD remote production application. To conduct the test, Media Links’ MDP3020 IP Media Gateways configured for 4K UHD video with JPEG-XS compression, and one of SMT’s largest OB production vehicles, which was previously deployed at the Summer Tokyo Olympics, were used.

SMT provides technical services for many major international events, including the Tokyo, Beijing, and PyeongChang Olympics, among many others. Media Links’ MDP3020 IP Media Gateways provide connectivity for multi-format video/audio signal transport as well as simultaneous data and control signal transfers between event venues and central operating and production centers. The MDP3020 also supports “hitless” or seamless protection switching of video, audio, and data services across two different network paths, allowing perfect signal reconstruction at the receiver should an intermittent disturbance or more permanent outage occur on any one network trunk path.

During the verification process, transmission delay and image quality of the transported content through the MDP3020 Media Gateways were closely evaluated using compression rates of 250Mbps, 500Mbps, 800Mbps and 2Gbps.

“In China, the impact of the Covid-19 pandemic is subsiding, and regular working conditions are returning,” comments SMT’s Technical Deputy Director. “In preparation for many anticipated sporting events and other remote production applications, we verified Media Links’ MDP3020 4K UHD (with JPEG-XS) IP Media Gateway. We paid particularly close attention to the low latency and high-quality transmission, which resulted in excellent verification measurements. We were impressed with the 3ms low latency along with the JPEG-XS compressed image quality that was almost equivalent to the original uncompressed image. We were also able to verify that encoded content can be produced, saved, and reprocessed, with no impact on post-transmission production work. Based on these results, the MDP3020 IP Media Gateway is an important candidate for consideration in upcoming projects.”

“With our extensive experience in high quality remote production applications, we are delighted that SMT turned to us to participate in this 4K UHD and JPEG-XS verification test,” adds Toshiyuki Naka, Media Links Senior Vice President of Asia Sales.“ We appreciate SMT’s discerning technical evaluation and look forward to furthering our partnership with them as they ramp up their technology and support services for more productions throughout the region.”
