The title is misleading, when they say low-delay, really they mean over UDP instead of TCP. Their answer to video over UDP is a marginal efficiency gain in a forward error correction algorithm called RLNC.
I haven't looked at RLNC, but it does seem to have some gains over more traditional FEC schemes.
