What is HDMI and why do I need it?

A single HDMI cable is the latest innovation to carry multiple-channel audio and high definition digital video signals from your Blu-ray player to your HDTV or HD projector. Connection is simple and only takes a moment. Because the HDMI cable eliminates the analog cable and is capable of transferring digital sources, the Blu-ray disc's source material remains in its original digital form and transfers without conversion directly to the HDTV for the best possible audio/visual experience directly from the disc.
