More and higher quality ultrahigh-definition (UHD) content is arriving in the production environment, requiring additional bandwidth for data transmission and exchange. In parallel, a more flexible infrastructure based on the well-known Internet Protocol (IP) stack is very desirable. Adding mezzanine compression in the production workflow can reduce the necessary data transmission capacities or even enable the usage of existing infrastructure designed for previous HD production lines for higher resolution and higher quality content. A low complexity of a mezzanine codec with ultralow latency, and preserving the highest quality, is one of the biggest challenges for such a new codec design. With this in mind, the Joint Photographic Experts Group (JPEG) committee started a New Work Item, called JPEG-XS, addressing the need for an interoperable video-over-IP codec. This paper presents the specific requirements for such a codec, shows the results of the call for proposals, and the advances during the core experiment phase, and provides some insight into the selected technology.
