It's just a tech preview, but our favorite high end Media Center maker, Niveus, is showing off Project Snowbird at NAB this week. Niveus hopes its PC client will help cable and satellite providers bring more premium HD content to the PC. This version was copying and streaming content from a Dish Network DVR and works with Sling's protocol, DLNA and DTCP-IP -- you remember it right, the CableLabs certified DRM for IP transport? Also baked in is Microsoft's PlayReady so envisioning playing the content on a Zune HD or in Media Center aren't too unfounded either. Dish Network was involved to show its commitment to working towards this type of solution in the home, but Niveus hopes to get all the providers on board and is anxious to fill in the PC client no matter what protocol the provider wants to use. We're told that these goals are inline with those of the IP Gateway we've been talking about, so it'll be interesting to see how this all shakes out. But at this point there aren't any product announcements and so this might just be yet another tech preview that never makes it to our homes. More shots of what it might look like after the break.
