Description
The IP Studio project at BBC R&D is investigating how we can produce live TV content using COTS servers and IP networks instead of specialised audio and video hardware. This could give us a flexible, cost-effective platform for creating both conventional TV programmes and new forms of immersive and interactive content for delivery over IP. This presentation will start with an overview of IP Studio and its architecture.
Summary
To preserve image quality and reduce delays, video in the studio is handled uncompressed or with only minimal compression. As we move to UHD (4K) resolution and higher frame rates, each of the cameras could be producing over 10 Gbit/s. We can buy the hardware to build 100 Gbit networks, but the challenge is to maintain this bandwidth all the way through the software stack and into user-space applications with no packet loss or re-ordering. Later in the presentation, we'll look at the techniques we're using that allow us to stream UHD raw video between servers at tens of gigabits per second.
