# DVR and sliding windows for live streams
Use the seekable window to rewind a live stream or jump back to the live edge.
Tip: open your browser's developer console and use the `player` and `THEOplayer` variables to interact with this demo.

A live stream can have `duration === Infinity`. The `seekable` ranges show the part of the live stream that is available for seeking. Open Video UI uses a live button to return to the end of the window.
```js
const lastRange = player.seekable.length - 1;
const liveEdge = player.seekable.end(lastRange);
player.currentTime = liveEdge - 30;
