Elecard has implemented simple functionality for the SDI capturing/rendering and DVB-ASI connection.http://www.elecard.com/products/embedded/fpga-solutions/hdaccess.php
We are going to add the smart DVB streams remultiplexer for ASI side in the near future. In regard to SDI we are planning to implement Colour Space conversion and denoising functionality. If the present functionality not covers your requirements we will be glad to realize it.
Please, share with us your dearest hopes
