All things related to multicast

["Rich Griffin (OSTN)" <>]

OSTN provides NASA-TV (and a few other free-to-air channels + OSTN, OSTN-Espanol, OSTN-UK) right now over our new platform IPTV system (Windows, Mac, Linux, STB).

Loughborough has an OSTN launch page now (http://www.ostn.tv/BrandedIPTV/OSTNVF/OSTNlboro.html) but they can watch it streamed from our data centers in Cleveland right now (although it is SD not HD - yet).

There is one NASA TV multicast that I know of, but it is not even 
640x480 and not sure which NASA channel it is.  The SAP announcement is 
LavaNet Video Test (NASA TV). I think the multicast IP is 233.25.35.4

I think it would be great if someone could deliver high quality stream 
of each of the NASA channels to I2.  I assume that if they are streaming 
them in low resolution from their website they would be happy to have 
them in high quality over i2 if someone else did all the work.
    

Once upon a time, NASA TV was the showcase because it was in MPEG1 and everything else was low-bandwidth window cams. Then NASA changed the satellite they were using, and the folks transcoding the signal into multicast lost the ability to see the bird. RIT has a downlink, but they are putting it into an admin-scoped group, and they won't even let me get it ;)

University of Alaska TV used to have NASA TV in between other programming, but it looks like they're now filling in time with ResearchChannel. You can try DVTS to 233.30.94.33/8000 and see what's on.

At one time, OSTN was providing a NASA TV channel that was accessible with a little bit of finagling. Their portal didn't work with my Mac, but I was able to convince it to give up the .nsc file for the feed, extract the group, and join it with VLC. That group no longer seems to work, and the portal is now locked down and won't let me connect. If you have OSTN access you might try to find it there. . .
