YouTube TV is adding some big new features, including 4K video, unlimited concurrent streams and offline viewing.

YouTube TV is one of the premier TV streaming services. The service is often compared with Hulu + Live TV, with the two duking it out for the top spot. One of YouTube TV’s biggest advantages is the power of Google behind it. As a result, the service has features, such as unlimited DVR space, that other services struggle to compete with.

The service is preparing to add additional features that will widen the gap even more.

“After just a few years, YouTube TV now has more than 3 million paid subscribers, 85+ networks, and offers unlimited DVR,” writes Neal Mohan, Chief Product Officer, YouTube. “Sports fans can even enjoy their favorite games with the ability to view key plays, hide spoilers, and check out real-time stats. And there’s more to come, including a new add-on option that lets viewers watch available shows in 4K or download them to their DVR to watch later offline. Plus, this option will add unlimited concurrent streams at home, so the whole family can enjoy YouTube TV on different screens at once.

With a starting price of $64.99, one of the most expensive options on the market, it remains to be seen if customers will want to pay more for another add-on package. 4K content and unlimited streams, however, may be enough to get customers to bite.
