Telefonica shows off streaming 4K video, won't make it fit your ISDN line

The future of TV is supposed to involve streaming video, and it's also supposed to involve 4K TVs -- but melding the two has been difficult. Telefonica wants to show that the feat is at least possible with mere mortal connections: it's been using Mobile World Congress to show 4K video streaming on a 100Mbps fiber-to-the-home link. As our Spanish teammates can attest, the (admittedly very local) demo works as well as you'd hope, providing all the fine details without buffering or other hiccups. There's no estimated timeframe for a commercial service, but we wouldn't hold out hope of a version that would fit on cable or DSL when there's a raw 40Mbps bitrate.
