What is HDMI?
High-Definition Multimedia Interface (HDMI) is a new type of plug connection between digital receivers, DVD players, game machines and TVs. It's fast becoming standard in most new devices and beats similar analogue devices like scart and component connections because of its quality and simplicity. It also has the ability to work with new and developing software protection methods required by programme content owners.
You'll need an HDMI cable to get a High Definition picture if you're wanting to watch selected programmes broadcast in HD with FreeviewPlus, Freeview|HD and MyFreeview|HD.
