Theory of HDMI • The High-Definition Multimedia Interface (HDMI) is an all-digital audio/video interface capable of transmitting uncompressed streams. HDMI also incorporates Digital Rights Management technology. HDMI provides an interface between any compatible digital audio/video source, such as a set-top box, a DVD player, a PC, a video game system, or an AV receiver and a compatible digital audio and/or video monitor, such as a digital television (DTV). • • It is a modern replacement for older analogue standards such as SCART or the RCA connector.

Why we need a HDMI Mux Switch? • Most of the existing Digital TV may only have one or two HDMI Inputs (平面 電視現在只有 1 或 2 個 HDMI 輸入口) • • More and more AV products such as (PS3, Blue-Ray Disc Player, HD DVD Player, HD STB, etc) will provide HDMI outputs (更多的產品有 HDMI 輸出) How do we connect them together using the HDMI link?
