Only signals from a 3D capable device, such as a 3D Blu-ray player or a 3D Set-top box or game console will enable you to enjoy the 3D experience on your TV.
In the near future, an increasing number of TV broadcasters will start to provide 3D signals, which can be picked up with a Set-top box that is connected by a high-speed HDMI cable.
At present however, the only device that can deliver a truly immersive home cinema experience in the Full HD 3D format,
is a 3D Blu-ray player.
