What products does eXtenHD make? What do you do?

You'll see many of our current products are based on the HDMI format – High-Definition Multimedia Interface.

HDMI is a multi-pin connection used for passing standard – and high-definition digital video signals, as well as multi-channel digital audio, through a single cable. These connections are usually found on newer HDTV tuners, and a growing number of DVD players, HDTV-ready televisions, and home theater receivers. HDMI cable accommodates up to 5 Gbps bandwidth, so it can simultaneously transfer pure digital video and audio signals without compression (even HDTV video).

HDMI works especially well with a "fixed-pixel" display (like a plasma, LCD, or DLP TV), and is backwards-compatible with most DVI connections. Signals are encrypted with HDCP (High-Bandwidth Digital Content Protection) to prevent recording.

Although many 1st generation HDMI-equipped components only pass 2-channel audio signals, HDMI can carry up to 8 discrete audio channels, making it forward-compatible with 7.1 sound systems. That means you can pass digital video and multi-channel audio signals between newer HDMI-equipped components along a single cable.
