Has anyone out there used Osprey for live streaming?

I am setting up a live streaming system for work and can't justify the cost of the stream genie (nor do I need the additional features it offers).

I am looking at the 220 and the 500. Has anyone used these cards? How well do they work in a Win2K environment? Initially there will only be up to 300 connections (though probably on average 50 - 100 simultaneous), but the intention is to roll it out across the whole company. We already offer on demand for resources/training etc.

Any thoughts gratefully received

We use Osprey 200 cards and they work very well. The picture quality is really good even though its using analogue composite input and depending of the sources the quality of the encoded video can be crystal clear, in fact I couldn't justify the cost of using the Osprey 500 firewire cards.

We are using Windows 2000 pro and I guess that would be the best choice if you are encoding in a Windows environment. It's too bad there are no drivers for Unix or Linux though, which would be interesting if encoding realvideo.

The only thing I don't like about the Osprey 200 is the audio control, it's a bit tacky. So maybe the Osprey 220 might be a good investment. The audio is good now but like I said the control is bad, having no volume meter display in the audio control panel.

Sometimes we still have encoding artifacts, the encoded video freezes for a while. Uninstalling/reinstalling the drivers helps in that case.

If you will do live broadcasting over you local intranet I would definitely suggest you set up some karaoke evenings with the network support department :)

Enabling multicast in your network will greatly improve the bandwdth consumption, 300 simultaneous users is quite a lot. What format/servers are you using?

Many thanks for your thoughts. We are using Dell servers and everything is running on 2K pro. I have been looking across the Cisco site as apparently there is loads of stuff there on Multicast and how to use Cisco routers and switchers to do a lot of the complicated stuff for you. I will post any links I find.

cheers for your thoughts though
