PCIe based 16 output DVB-ASI Streamer Card Development -- 2

We have a 4 output DVB-ASI Streamer PCIe card. For the PCIe function we use a PLX device which is now obsolete. We wish to use an Altera device for the PCIe function & increase the outputs to 8 independent outputs + 8 copies in the new version. Full development is ideal. But are also able to carry out some of the tasks.
