NEW YORK (AP) - Every Olympic event will be streamed live. But to watch online, you'll still need to pay for a cable or satellite subscription.

If you've already given up on cable or satellite TV, you can sign up for an online TV service such as PlayStation Vue or YouTube TV. Otherwise, your video will cut out after a half-hour grace period.

The subscription requirement also applies to coverage of 30 events on virtual-reality headsets. That includes 18 live events, or 55 hours.

More than 1,800 hours of online coverage begins Wednesday evening in the U.S. with preliminary curling matches. Friday's opening ceremony will be shown live online starting at 6 a.m. ET, and on NBC's prime-time broadcast on a delayed basis at 8 p.m.
