Verizon has lit up 4K FiOS Fox Sports programming, in something of a test, on channel 1498 and 1499. NASCAR was first to air on FS1 4K a few weeks back and now we’ve got a month of the World Cup. As far as I can tell, any FiOS package that includes Fox Sports and running capable hardware should do the trick.
Of course, Verizon isn’t the only television provider dabbling in ultra HD. But this is the first 4K-on-TiVo mention I’m aware of. I can’t recall if linear 4K capabilities were present at Bolt launch, but dormant until content became available, or if it had been implemented over the intervening months. In any event, the stars have aligned and it’s all here now — both viewing and recording, clocking in a reasonable but rich ~21-23mbps according to one viewer.
