1 SDI Plugin Module (1x slot)
The photonSDI system consists of:
1) a development test system with two off-the-shelf circuit boards: an evaluation board and an SDI interface board to handle electrical conversion.
2) A prototype implementation of a custom caseboard that plugs directly into the Axiom Camera and adds SDI connectivity.
1.1 How it works
- A description of a desired SDI connectivity is created using the LiteX framework (a fork of Migen).
- The framework generates a Hardare Description Language (HDL) reprensentation in Verilog.
- The HDL is passed to the tool chain, which generates a configuration for the chip on the evaluation SDI Extension Board.
- The configuration is loaded onto the chip on a base board that is plugged into the camera.
- Camera with chip has new functionality for connecting to professional SDI video equipment.
1.2 Technical Details
Implemented in:
- Hardware description language loaded into chips
- Litex, a Python framework for building custom hardware
Supported hardware platforms:
- Field programmable gate array (FPGA) evaluation board AC701 + SDI interface evaluation board TB-FMCH-12GSDI
- apertus AXIOM Beta + SDI plugin module
1.3 License
Source code is available on GitHub.
PhotonSDI is released under the very permissive two-clause BSD license. Under the terms of this license you are authorized to use PhotonSDI for closed-source proprietary designs. Even though we do not require you to do these things, we'd be grateful if you did:
- Tell us that you are using photonSDI.
- Cite photonSDI in publications related to research it has helped.
- Send us feedback and suggestions for improvements.
- Send us bug reports when something goes wrong.
- Send us the modifications and improvements you have done to photonSDI.
1.4 Notes
The initial development is sponsored by the German Federal Ministry of Education and Research (BMBF) via their Prototype Fund.
An industry standard serial digital interface (SDI) connection plugin module will provide a nominal data transfer rate of 3G/6G.
Projects using PhotonSDI: apertus AXIOM Beta, HDMI2USB, Numato Opsis.
