A Freeview box connects to your TV and receives free-to-air freeview channels, no subscription or monthly payment needed. Simply purchase a Freeview set top box or Freeview HD set top box and plug it in to your TV and your TV aerial. A Freeview box can be used with any TV, it doesn't need to be a digital TV. A HD Freeview set top box however would require a HD TV to enjoy high definition channels. A Freeview box when used with a non digital TV means that your TV would now receive Freeview TV.
