VIERA Link Now you can enjoy the beautiful sounds and pictures of highquality AV equipment without all the messy, unsightly cables. With HDMI, a single cable* carries the video, audio and control signals between two digital components. By using VIERA Link (= HDAVI-Control) compatible components, you can turn on the power for your entire home theater with a single remote control button, and begin playback immediately. Operating your DIGA recorder is easier and smarter too.
