HDMI (High-Definition Multimedia Interface) is the brand new A/V solution that brings a whole new entourage of features to your home theater. You do not have to worry about cables getting tangled, since a HDMI cable is compacted of audio and video interface that is transmitted within one cable.

It transmits high-definition video signals up to 1080p resolution, and 5.1 surround sound audio including the high-definition audio formats available on Blu-ray.

HDTV - High definition television. HD television is any signal that conforms to the HD standards. That means any signal of 720 lines, 1080 lines or (now obsolete) 1035 lines. There are a number of different frame rates associated with each resolution so there are about 25 separate HD formats worldwide.

HDMI - High definition multi-media interface. This is the accepted standard for domestic HD signal connections between receivers and televisions. The single cable carries video and audio signals as well as other data. It also supports encrypted signals using HDCP (high definition copy protection) which prevents unauthorized users extracting and copying the signal. HDMI also supports standard definition signals and many digital computer display signals (it is compatible with DVI digital signals).
