Glossary A–ZLetter L
Live TV
Live TV means that a running television programme is shown on a digital signage screen, either on its own or in one area alongside other content.
The signal comes from a receiver for terrestrial, cable or satellite reception, or as a data stream over the network.
Typical locations are waiting areas, canteens, hotel lobbies, sports venues or restaurants and bars. The television picture is often placed in one area of the layout while the operator's own notices or a ticker run beside it. Some displays have a built-in receiver; with others, an external device feeds in the picture via HDMI, or the player plays a network stream.
Operators should clarify two things. Technically, live TV depends on a stable reception source and a player that can accept the signal; not every player can integrate an HDMI signal into a layout. Legally, the public playback of television programmes usually requires payment of fees, for example for the music they contain. Special conditions may apply to broadcasts of certain events, such as major sporting events. In addition, television carries third-party advertising that the operator does not control.
