Huge public TV screens are becoming increasingly popular - whether outdoors or inside in venues such as shopping centres. The public love them and they enhance the atmosphere in parks and venues. In the UK, crowds have shared the experience of everything from royal weddings to the Olympics, major sporting events and even just big soap-opera moments.

Until now, the sound is more of a problem. Many screens run with subtitles. With LimeOnAir, anyone can hear the audio directly on their smartphone. You can even offer multiple languages if you wish.
