50Mb/s would be pretty low for HD with the T-VIPS. I recall needing 80Mb+ to get a decent HD image. The ultra-low latency and image quality is awesome, though, given sufficient bandwidth.

For sub-50Mb/s links, you could consider an MPEG2 or MPEG4 codec from Tandberg or Fujitsu. They're  higher latency, but good quality at those bit rates.

I've never tried any of these on public Internet links, only private WAN, so I haven't a clue how well they'd perform on the Internet.

+1 for T-Vips.

Marshall makes an H.264 streaming box which you can have with HD-SDI input:

Only does 1080/59.94i for now, although we've been promised support
for 1080/23.98psf.

Fairly low bitrate, 6-8 mbps I think?
