HomeTech: New Digital Media Interface: "Each HDMI cable can replace all the audio and video cables needed to display a high-definition image with Dolby Digital surround sound, simplifying installation and, once most devices become HDMI-compatible, putting an end to cable clutter. The connectors will also be able to send setup information between devices. For example, if a manufacturer includes the necessary software, the HDMI connection can send a signal from the DVD player to the digital television, telling it that the movie it is about to play is coming in on input 1 and will be in wide-screen format. The TV can then automatically change its settings. "
