Google Cast and Apple TV boxes offer you the possibility of streaming the Digital Concert Hall on your TV. You do not need a Smart TV for this. Both devices are connected to your TV via HDMI. You can now connect your smartphone or tablet to Google Cast or the Apple TV box via a Wi-Fi connection and enjoy the Digital Concert Hall on your TV.
