Blackmagic IP10 Video Codec

You can send uncompressed ST 2110 IP video over 10G Ethernet at frame rates up to 2160p50

Ultra HD, just like on an SDI video network. For the high frame rates, like 2160p59.94 and

2160p60, you’ll need to lower the data rate enough to fit down a 10G Ethernet port. This

is where Blackmagic IP10 comes in. It’s a simple ‘codec’ that changes from pixels being an

absolute quantizing level as used in normal uncompressed video to a difference number that

shows the difference between pixels. On hard edges in the image, it can also reduce the bit

depth of these pixels because it’s not visible.

The goal is to fit a 12G-SDI signal into a 10G Ethernet port, so only a little bit of image data

needs to be removed. The big advantage of using 10G Ethernet for high frame rate Ultra HD

video is a dramatically lower cost because products can be simple and use less power. This

makes IP mini converter type products possible and the cost of Ethernet switches is also

much lower as low cost 10G Ethernet switches are very common. You can also use simple 10G

Ethernet copper cables that are already installed in a lot of buildings and you even have the

option to remove power converters over PoE.
