Digital Video Recorder or sliding window lets your viewers pause or scrub back in time.
THEOplayer will automatically detect if an HLS live stream is a DVR stream so there is no need for any configuration. When a DVR stream is detected, the viewer can use the sliding window to seek back in time or catch up to the live section afterwards while the live event is in progress.
DVR is a feature that is enabled in some live streams. They allow you to go back in time.
