BBC Optimizing UHD Video Streaming Over IP (bbc.co.uk)

johnslater writes: A friend at the BBC has written a short description of his project to deliver UHD video over IP networks. The application bypasses the OS network stack, and constructs network packets directly in a buffer shared with the network hardware, achieving a ten-fold throughput improvement. He writes: "Using this technique, we can send or receive uncompressed UHD 2160p50 video (more than 8 Gbps) using a single CPU core, leaving all the rest of the server's cores free for video processing." This is part of a broader BBC project to develop an end-to-end IP-based studio system.

This isn't for you to watch UHD. It's for internal use in production, so they can shunt live UHD video around their studios. That way they keep full quality right up until the final stage before distribution, when it gets resized according to the end device. Your TV will get plain old 1080p as always - but they'll have UHD capability ready to go for transmitting to cinemas or sending to big public displays, and they can archive a UHD version for future use so they can zoom in tighter on the action in future highlights.
