What is Raven?
From Raven Wiki
Raven is a multi-port broadcast video server, currently only available within the BBC, using Blackmagic SDI video cards.
The project was commissioned by BBC Newsgathering as a VTR replacement for their satellite trucks, but it has found many other applications.
The main advantage of Raven is its flexibility. It uses off-the-shelf consumer PC hardware, and can be configured in a variety of different ways:
- 1-4 ports of video input/output
- fast SSD or large SATA drives
- rackmount case or small form factor
- quad-core i7 processor for 4 port recording or ITX-motherboard and core i5 for mini form factor.
We recommend particular hardware combinations that have been tried and tested, but if you want to come up with your own spec, then go ahead. Make sure you test it fully before using it in for any serious use, though.
