For 1080p/30 you could do 4:2:0 or 4:1:1 compression and it should then fit on a single Gigabit Ethernet. If you want to store this you'd need a dedicated RAID array. Then later you could do the time compression slowly, no supercomputer needed. I am assuming that doing the 4:2:0 or 4:1:1 compression is relatively simple. Note however, that dealing with Ethernet at these datarates takes a lot of CPU. There are Ethernet controllers that offload some of this, although I've read that some don't actually work properly. And you'd need a true real-time OS, you can't afford any latency in servicing the Ethernet. If the box has enough CPU/DSP to decode H.264, it might be enough to encode using a simpler codec, like mpeg2 ? _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
