Caption timing

The Caption timing panel, with Caption sync set to 0.5s and Caption timeout set to 5s.
  • Caption sync holds the picture back, by up to a second, so it reaches the TV at the same time as its captions. The picture pauses for a moment when captions start. Choose Off to show the picture straight away. The blue button on the remote changes it too.
  • Caption timeout is how long a caption stays on screen after the speaking stops. With Off, captions stay until the next ones replace them.

Streams

With Stream mode set to Receive, XRAI TV lists the XRAI streams it finds on the network, such as the captions from a venue's XRAI Studio. Choose one to show its captions on the TV.
