While the ability to stream a DVR's content to an iPad of iPhone can be found on other devices, Tivo says that Tivo Stream is unique in that it will let you watch a recorded show on multiple devices without affecting what's being watched on the TV. Also, Tivo says that Tivo Stream will have support for transferring a recorded show to an iOS device "for viewing outside the home."
However, to use Tivo Stream, you'll need to have a box, which start at $150, plus a service plan that costs $15 per month (or you can pay a one-time $500 fee for the life of the box).
Tivo also announced a new product, the "IP set-top box," that will allow owners of the Tivo Premiere Q to view content on secondary TVs in the home.
Tivo did not release pricing and availability for Tivo Stream or the IP set-top box, but both products will be available through retailers and through TV service providers.
