Broadcast service and technology provider Shanghai Media Tech (SMT) recently teamed up with Media Links to evaluate a 4K Ultra HD (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 outside broadcast (OB) production vehicles, which was previously deployed at the Summer Tokyo Olympics, were used.
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 preparation for many anticipated sporting events and other remote production applications, we verified Media Links’ MDP3020 4K UHD (with JPEG-XS) IP Media Gateway,” said a spokesman for SMT. “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.”
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 centres.
The MDP3020 also supports “hitless” protection switching of video, audio, and data services across two different network paths, allowing signal reconstruction at the receiver should an intermittent disturbance or more permanent outage occur on any one network trunk path.
