CES 2016: TV plays different audio to two viewers

A special speaker system that allows two people to sit side-by-side in front of a split-screen TV listening to different shows, is attracting attention at CES.

Holosonics says its sound-beaming technology means someone could also watch TV in bed without keeping their partner awake as only the watcher need hear the audio.

The catch is that it costs about $1,000 (£685), making it an expensive alternative to a pair of headphones.

Cristofer Osden, the firm's technical sales manager, explained how it works to the BBC's North America technology reporter Dave Lee.
