Abstract
Broadcasters are beginning to use the public cloud for live production, but unlike ground-based production, most of the media processing in the cloud operates on compressed media. One public cloud offers a solution for uncompressed transfer but that solution currently has some limitations that prevent widespread use between customers. We have had some success transporting uncompressed video on several clouds using a multiflow User Datagram Protocol (UDP) transport, which is described in this article. We also discuss the expected architecture of cloud services that process video, and some of the areas where standardization will be needed. There are many use cases for compressed media in the cloud, and many of them will remain for a long time. For the near future, due to business, technical, and standardization issues, we see uncompressed video transport relegated to an internal implementation detail of services that will continue to use standardized compressed formats for ingress and egress.
