More technical details at

Brief explanation

Add support for 3G Serial digital interface for the HDMI2USB.

This project will let us push and pull lots of data over a wider range of protocols / cables / system.

Detailed Explanation

SDI interface is used by a large number of high end devices. It would be good for the HDMI2USB firmware to support the standards and protocols.

This will probably require development of a TOFE expansion board which has SDI connectors, otherwise some way to adapt the DisplayPort connector to SDI.

I am interested in paying somebody who can bring this extension board to finished PCB.
The goal is to get Video, Audio and KLV data out from SDI. Please ping me if you are interested.
