BBC to Trial Worldwide Multicast Streaming?
An anonymous reader writes "There are tantalizing hints, via The Inquirer, and other tech news sites, that the BBC may extend its multicast streaming services to non-UK citizens, for material where rights allows. There's details about how ISPs may peer to join the multicast trial network on an official BBC page." We previously covered the BBC's multicast streaming of the Olympics, unfortunately not available in the U.S.
You can find out about what multicast is and what it means by checking out this Cisco page that explains what it actually is.
As always, Google is your friend...
I have no problem with your religion until you decide it's reason to deprive others of the truth.
Hi, I'm one of the BBC R+D engineers working on the multicast project.
:-)
We restrict the Olympics streaming to UK ISPs who multicast peer with us, and the participating ISPs have to make sure that they don't let this multicast down non-UK routes.
Sounds crude, but it's an incredibly effective way of doing it, and it avoids the need for intrusive things like credit card verification (which also doesn't work as well).
Sadly we need to be really careful about how our Olmpics coverage is allowed out, since it's a big deal for the IOC to allow us to stream it at all, and they have only granted us rights for the UK. The IOC tend to notice when people overstep their agreed rights too, so people absolutely must play nicely (you can understand that, it's their event, after all).
As an aside, the material itself is a really interesting test for the coders, and we hope to be able to supplement the real10 stuff with an H.264 stream (H.264 is the mpeg-4 advanced video codec) at some point. The tough part is finding distributable players which can handle this newish standard. VLC is a wonderful multi-platform player, but sadly only copes with H.263 at the moment, the 264 support isn't there *yet*. Quicktime won't know 264 until Tiger comes out, and Windows Media needs special plugins for it.
MPlayer depends on ffmpeg etc in the same way as VLC, too, so that's not an option- shame, I am too used to MPlayer playing anything I throw at it- the BBC's "Blue Planet" looked great in ascii art
Anyway, it has been a really interesting project so far, and we hope to be able to keep going with it, the results are very promising. Thanks for the slashdot writeup too, it's nice to have your efforts noticed, sometimes you feel a bit invisible in the techie bits of a media organisation.
