When these first started appearing on the back of such equipment there was no real use for them.
Recently, however, software upgrades have made many of these network connections useful. It is possible to connect your TV or set-top box to an internet connection and access content, such as BBC iPlayer, ITV Player and so on, directly from your TV or set-top box rather than a computer.
If your internet connection is not within easy reach of your TV or set-top box then Cable Guys can install a cheap and easy network cable to connect the two giving you access to this and any other online content that becomes available. This will usually only cost £45 and will unlock the full potential of your television.
